Answer:
C, A, A
Step-by-step explanation:
In general, you ...
identify the coefficients of one of the variablesswap them, and negate one of themmultiply the corresponding equations by the "adjusted" coefficients.__
In problem 1, the x-coefficients are 8 and 2. A common factor of 2 can be removed so that we're dealing with the numbers 4 and 1. Assuming we want to multiply one of the equations by 1, leaving it unchanged, the value we want to multiply by will be -4. After we swap the coefficients, that multiplier is associated with equation 2:
multiply equation 2 by -4 . . . (eliminates x)
Likewise, the y-coefficients in problem 1 are -1 and 3. Again, if we want to multiply one of the equations by 1, leaving it unchanged, the coefficient we will change the sign of is -1 (becomes 1). After we swap the coefficients, the multiplier 3 is associated with equation 1:
multiply equation 1 by 3 . . . (eliminates y)
These two choices are B and A, respectively, so the one that does NOT work for problem 1 is choice C, as indicated below.

The other problems are worked in a similar fashion.
can anyone help me create the equation of the given parabola . is it x^2-x-3?
Answer:
The function of this parabola is is equal to [tex]f(x) = (x-1)^{2} - 4[/tex]
Step-by-step explanation:
If we look at this picture we cans see that the most bottom point of this parabola is located 4 units below and 1 unit tot he right of the origin point. From here we know tha tthe function will lokk something like this....
[tex]f(x) = (x^-1)^{2} + bx - 4[/tex]
But in our case b is equal to zero and so we get that the following parabola is represented by the following function....
[tex]f(x) = (x-1)^{2} - 4\\[/tex]
(If you don't believe me you can check this function on a graphing site called Desmos)
the cost per month of making n number of wooden toys is 3n + 30. the income from selling n toys is 6n. how many toys must the company make to make a profit
Answer:
3×6=18+30=48. so company needs to make 48 toys
Answer:
n > 10, or n = 11. Not sure which answer fits your hw better.
Step-by-step explanation:
6n > 3n + 30
6n-3n > 30
(3n > 30)/3
n > 10
So, you need to sell 10 toys in order to break even, which means you need to make and sell 11 toys at least to make a profit.

Sneakers at Mr. Lou's garage sale cost the same price. Alexander paid $90.52 for four pairs. How many pairs of sneakers did Justin buy if he paid $135.78? Write a proportion and use cross products to solve for d, the number of sneakers that David bought
Answer:
6 pairs
Step-by-step explanation:
Since we are given a ratio/proportion problem and 3 values and 1 variable then we can use the Rule of three to solve this problem. We simply multiply the diagonal values available and divide by the 3 value to find the variable of the ratio like so...
4 pairs <======> $90.52
d pairs <======> $135.78
(4 * 135.78) / 90.52 = 6 pairs
Finally, we can see that Justin ended up buying a total of 6 pairs of sneakers.

Answer:
The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}
Step-by-step explanation:
The domain is the set of values of the input (x)
The range is the set of values of the output (y)
In the given figure
∵ x is the input
∴ The set of the values of x is the domain
∵ Y is the output
∴ The set of the values of y is the range
∵ The smallest value of y is -6
∵ The greatest value of y is 8
→ That means values of y of the graph are from -6 to 8
∴ -6 ≤ y ≤ 8
∴ The range = {y : y ∈ R, -6 ≤ y ≤ 8}
∴ The range of the graph is {y: y ∈ R, -6 ≤ y ≤ 8}

Hal is downloading a file from the internet. So far he has downloaded 25% of the file.
If 10 minutes have passed since he started, how long will it take to download the rest of the file?
Answer:
30 minutes
Step-by-step explanation:
If it takes 10 minutes to download 25%, and there is 75% left to reach 100%.
25% + 25% +25% = 75% there are 3 25% left thus,
10min + 10min + 10min = 30 minutes left to complete download.
The amount of time in minutes it will take to download the rest of the file
is 30 minutes.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Let, 'x' be the number of minutes required to download the complete movie.
Therefore,
25% of 'x' is 10 minutes, This can be numerically expressed as,
(25/100)×x = 10.
0.25x = 10.
x = 10/0.25.
x = 40 minutes.
So, it would take 40 10 = 30 minutes.

a ball is launched upward from the ground with an initial velocity of 20 ft/s. The height of the ball at time t is represented by the function h(t). h(t)=-16t^2+20t, where t is measured in seconds and h(t) is measured in feet. drag the values to the lines to complete each sentence.
1. The ball reaches its maximum height when t is ____ seconds.
2. The maximum height of the ball is ____ feet.
3. The balls hits the ground when t is ____ seconds.
OPTIONS: 0.4 0.625 0.8 1.25 5.44 6.25 12.5 25
Answer:
1.-t₁ = 0,625 s
2.-h(max) = 6,25 f
3.-t = 1,25 s
Step-by-step explanation:
V₀ = 20 f/s
h(t) = - 16*t² + 20*t
h(max) = ??
h´(t) = - 32*t + 20
h(max) will occurs when V = 0 dh/dt = 0 then
- 32*t + 20 = 0
- 32*t = -20
t = 20/32
t₁ = 0,625 s
h(max) = h(0,625) = - 16*(0,625)² + 20*0,625
h(max) = - 6,25 + 12,5
h(max) = 6,25 f
c) The ball will hit the ground
t = 2*t₁
t = 2*0,625
t = 1,25 s

Step-by-step explanation:
Lily, Juliet, and Willow are baking muffins. Lily has 1 1/2 cups of flour, Juliet has 3/4 cup of flour, and Willow has 1 2/6 cups of flour. How many cups of flour do they have altogether?
Answer: 3 7/12
Step-by-step explanation:
From the question, we are given the information that Lily has 1 1/2 cups of flour, Juliet has 3/4 cup of flour, and Willow has 1 2/6 cups of flour.
The number of cups of flour that they have altogether would be the addition of all the fractions of each girl. This would be:
= 1 1/2 + 3/4 + 1 2/6
The lowest common multiple is 12, therefore we make them have a common denominator
= 1 6/12 + 9/12 + 1 4/12
= 2 19/12
= 2 + 1 7/12
= 3 7/12 cups
independent practice: tangents of circles
Find the value of x in each of the following:
(see picture)
Answer:
Step-by-step explanation:
9). "Tangent is perpendicular to the radius of a circle"
By applying Pythagoras theorem in the given triangle,
x² = 15² + 20²
x = √625 = 25
10). By applying Pythagoras theorem in the given triangle,
(r + x)² = r² + 15²
(8 + x)² = 8² + 225
8² + x² + 16x = 8² + 225
x² + 16x = 225
x² + 16x - 225 = 0
x² + 25x - 9x - 225 = 0
x(x + 25) - 9(x + 25) = 0
(x + 25)(x - 9) = 0
x = -25, 9
But x > 0
Therefore, x = 9 is the answer.
11). By the property of the tangents drawn to the circle from a point,
"Tangents drawn from a point lying outside the circle are equal in measure"
AC = BC
3x + 4 = 40
3x = 36
x = 12
12). By the same property used in question (11)
DE = DC = 4 units
BA = BC = 3 units
x = 4 + 3 = 7 units
