Answer:
700, 225, 25, -25
Step-by-step explanation:
In the question given, we have to fill the blanks in the situations to describe an opposite quantities which combines to make zero.
1. Nick returned home descending 700 feet later at the day because he climbed a hill that was 700 feet high.
2. Jack deposited an amount of $225 in his account but later that week, he bought a new TV by withdrawing the amount of $225 from his account.
3. Janine dove into the sea to look at the coral reefs to a depth of 25 feet, and then she swam back to the sea surface by swimming 25 feet upwards.
4. The final temperature at the end of the day was -25 degrees, as the morning temperature was -25 degrees and then at daytime, it rose for 5 degrees and then again dropped by 5 degrees.
Triangle ABC has coordinates A (0, 4), B (1, 3), and C (-2, 4). If triangle ABC is reflected over the x axis and then translated such that (x, y) → (x+3, y-1), what is the resulting image of point C?
The resulting image of point C is C''(x, y) = (1, - 5).
What are the coordinates of the image of a point by using a rigid transformation?
The triangle seen on the Cartesian plane is generated by three points on that plane. The image of the triangle is the result of reflecting the three vertices over the x axis and later translating them 3 units in the +x direction and a unit in the - y direction, two kinds of rigid transformations.
Now we proceed to show the entire procedure:
Reflection over the x-axis
C'(x, y) = C(x, y) + (0, - 2 · c)
C'(x, y) = (- 2, 4) + (0, - 8)
C'(x, y) = (- 2, - 4)
Translation
C''(x, y) = (- 2, - 4) + (3, - 1)
C''(x, y) = (1, - 5)
The resulting image of point C is C''(x, y) = (1, - 5).

After finding the fish you would like to take home to cook, you discover it cost $2 to wrap the fish and $4.50 per pound. Another vendor is selling another fish for a flat rate of $5 per pound. Explain how you could find the equivalent cost at each vendor.
The total cost of wrapping for both fishes are given by 4.5x + 2 and 5x respectively.
What is an equation?An equation is used to show the relationship between numbers and variables. An equation can be linear, quadratic depending on the degree.
Let x represent the number of pounds of the fish.
For the first fish, cost = 4.5x + 2
For the second fish, cost = 5x

At a carnival game, the chance of winning a prize is 0.45. Kylee plays the game 3 times. Using the table, what is the probability that she wins at most 2 prizes?
0.09
0.33
0.58
0.91
The probability of winning one prize in 3 attempts is P = 0.41.
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, the chance of winning a prize is 0.45, Kyle plays the game 3 times. we need to find the probability that she wins at most 2 prizes
Out of 3 attempts, the probability of winning one prize is:
P(1) = (0.45)x(0.55)²p
where p is the number of permutations, you can win on the first attempt, second attempt, or third attempt, so there are 3 permutations.
Then the probability is:
P(1) = (0.45)x(0.55)²x3 = 0.41
Hence, the probability of winning one prize in 3 attempts is P = 0.41,

On a coordinate plane, how are the locations of the points (-3 , -8) and (3 , -8) related? A. reflection across the x-axis B. reflection across both axes C. reflection across the y-axis D. locations unrelated
Given:
The locations of the two points are (-3 , -8) and (3 , -8).
To find:
The relation between two points.
Solution:
From the given points (-3 , -8) and (3 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.
If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,
[tex](x,y)\to (-x,y)[/tex]
For (3,-8),
[tex](3,-8)\to (-3,-8)[/tex]
So, it is reflection across the y-axis.
Therefore, the correct option is C.
Answer:
reflection across the x-axis

A plane traveled 3355 miles with the wind in 5.5 hours and 2585 miles against the wind in the same amount of time. Find the speed of the plane in still air and the speed of the wind.
HELP QUICKKKKK
Answer:
Speed of the plane in still air is 540 mph,Speed of the wind is 70 mph
=======================
Let the speed of plane is x and speed of the wind is y.
The speed of the plane with the wind is x + y and speed of the plane against the wind is x - y.
Equation for speed:
speed = distance / timeSince the same amount of time spent in both cases, we can set equations:
x + y = 3355/5.5 ⇒ x + y = 610x - y = 2585/5.5 ⇒ x - y = 470Add up the two equations and solve for x:
x + y + x - y = 610 + 4702x = 1080x = 540Find y:
540 + y = 610y = 610 - 540y = 70
Translate (3, – 4) down 3 units.
Then reflect the result over the y-axis.
Answer:
Step-by-step explanation:
Best advice: make a sketch (which I can't do here).
When you reflect in the x axis, only the y value changes...so (3, -4) reflects to (3,4).
Translating down (i.e. in the negative direction) again means the x value (the abscissa) doesn't change, only the y value (the ordinate)...so the final value of the point is (3,1).

x=−10
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x−6)+2=6x−2
Step 1: Simplify both sides of the equation.
4(x−6)+2=6x−2
(4)(x)+(4)(−6)+2=6x+−2(Distribute)
4x+−24+2=6x+−2
(4x)+(−24+2)=6x−2(Combine Like Terms)
4x+−22=6x−2
4x−22=6x−2
Step 2: Subtract 6x from both sides.
4x−22−6x=6x−2−6x
−2x−22=−2
Step 3: Add 22 to both sides.
−2x−22+22=−2+22

Jordan is starting to save $150 to buy a new cell phone. In December, he saved $5. In January, he plans twice as much as he did in December, for a total savings of $15 ($5 + $10). If Jordan continues to save twice as much he saved from the previous month, in which month will his total savings will be enough to buy the phone.
9514 1404 393
Answer:
April
Step-by-step explanation:
The sequence of amounts saved is a geometric sequence. The sum of those amounts is given by the formula ...
Sn = a1·(r^n -1)/(r -1)
where a1 is the amount saved in month 1, r is the common ratio, and n is the number of months. We want to find n such that ...
150 ≤ 5(2^n -1)/(2 -1)
30 ≤ 2^n -1
31 ≤ 2^n
We can solve this using logarithms, or we can make use of our knowledge of powers of 2: 2^5 = 32. That is, n = 5 will be the first month when Jordan's total savings exceeds $150.
The fifth month will be April. Jordan's total savings will be enough in April.

The attached shows a spreadsheet that computes Jordan's amount of savings each month, and his running total. Once the formulas are written, they can be copied down as far as required to see where the total savings is enough.
Does 12cm, 7cm, 5cm, make a triangle
Answer:
No, it doesn't.
Step-by-step explanation:
In order to find what makes a triangle, lets use the Triangle Inequality Theorem!
This theorem can help us show whether the sum of two side lengths of a triangle is greater than the third side or not
Here is our formula(s):
1.) a + b > c
2.) a + c > b
3.) b + c > a.
Lets make a=12, b=7, & c=5
1.) 12 + 7 > 5
19 > 5
2.) 12 + 5 > 7
17 > 7
3.) 7 + 5 > 12
10 > 12
As you can see, both numbers 1 and 2 shows to be correct but 3 is not. Therefore it doesn't make a triangle. Remember, if all the two side lengths of a triangle is greater than the third side, then it makes a triangle.
The difference of two integers is 5. Twice the smaller integer is 8 more than the larger integer. What are the two integers?
Answer:
18 and 13
Step-by-step explanation:
The two numbers are 13 and 18 respectively.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the difference of two integers is 5. Twice the smaller integer is 8 more than the larger integer.
Assume the number to be [x] and [y]. We can write -
x - y = 5
2y = x + 8
2y = 5 + y + 8
y = 13
Then -
x = 13 + 5
x = 18
Therefore, the two numbers are 13 and 18 respectively.

Considering the roots of function f(x), the correct statement is given by:
D. f has exactly two zeros of [0,4].
What are the roots of a function?The roots of a function are the values of x for which f(x) = 0.
In this problem, we have that:
f(2) = 0, hence x = 2 is a root.f(3) < 0 and f(4) > 0, meaning that between x = 3 and x = 4, there is a root of a function, as to go from negative to positive, it has to pass through f(x) = 0.For values of x less than 2 on the interval, the function is never negative nor zero, hence there are no roots in that interval and option D is correct.
