1) Graph this situation on
2) What does the graph tell you about the situation and how many solutions there are?
Answer:
ok so the graph tells you 24 seconds by 4 ounces
Step-by-step explanation:
The point where both lines meet is the point where they are both equal.
The point where both lines meet is (24,4)
Since the x-axis represents seconds the x-coordinate will represent the number of seconds it takes for them to be equal which is 24.
Since the y-axis represents ounces the y-coordinate will represent the number of ounces they have when they are equal which is 4.

Slove using substitution
Y= 2x + 1
3x + y = 11 Step by step explanation
Answer: x = 2 and y = 5
Step-by-step explanation:
y = 2x + 1
3x + y = 11
Substitute
3x + (2x + 1) = 11
5x + 1 = 11
Subtract both sides by 1
5x = 10
Divide both sides by 5
x = 2
y = 2x + 1
Substitute
y = 2 (2) + 1
y = 4 + 1
y = 5
In 2006, there were 141 Asiatic lions in India . In 2011, there were 252 Asiatic lions in India Work out the percentage increase in the number of Asiatic lions in India from 2006 to 2011
Answer:
The percentage increase is 78.72%
Step-by-step explanation:
Here, we want to calculate a percentage increase
We proceed to use the mathematical relation as follows;
Percentage increase = (new value - old value)/old value * 100%
new value is value in 2011 = 252
old value is value in 2006 = 141
Substituting these values, we have;
(252-141)/141 * 100%
= 111/141 * 100%
= 78.72%
please help me will mark brainliest!!! Evaluate √-72k where k= -2
Step-by-step explanation:
Given
k = - 2
Now evaluating
√- 72 * - 2
= √ 144
= √ ( 12)²
= 12
Hope it will help you :)❤
The evaluated solution of √-72k for k = -2 is 12.
What is an expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given expression as :
⇒ √-72k
And k= -2
To Evaluate the expression
Now Substitute the value of k= -2 in the expression
⇒ √- 72 × - 2
⇒ √ 144 [√ 144 = 12]
⇒ 12
Hence, the evaluated solution of √-72k for k = -2 is 12.

An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t. How fast is it flying? Be sure to include the units.
Answer:
v=0.15 miles per second
Step-by-step explanation:
The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15t.
We need to find how fast is it flying.
Differentiate the given equation wrt t.
[tex]\dfrac{dd}{dt}=\dfrac{d}{dt}(0.15t)\\\\\because \dfrac{dd}{dt}=\text{velocity(v)}\\\\v=0.15[/tex]
It means the velocity of the airplane is 0.15 miles per second.

y+1/4x+3
pls help solve for x and y
Answer:
x+y+3 or 1x+1y+3
Step-by-step explanation:
3/4x+1/4x+1y+3
3/4x+1/4x=1x
1x+1y+3
You can't do x+y+3 so it stays x+y+3. Hope this helps.
When a stepladder is placed as shown, is it possible for the lower ends of the ladder to be 12 feet apart? Explain
Answer:
No, with the guides in between the two ladders, it is not possible for the lower ends of the ladder to be up to 12 feet apart
Step-by-step explanation:
The given parameters are;
The length of two sides of the step ladder = 12 feet
The maximum value allowable for the included angle between the two 12 feet ladders = 58°
Therefore, the maximum value of the third side facing the included angle is given as follows;
let "a" represent the maximum value of the third side formed by the distance apart of the lower end of the ladder, by cosine rule, we have;
a² = 12² + 12² - 2 × 12 × 12 × cos(58°) = 135.383251901
∴ a = √(12² + 12² - 2 × 12 × 12 × cos(58°)) ≈ 11.64
The maximum value of the third side formed by the distance apart of the lower end of the ladder = a ≈ 11.64 feet < 12 feet
Therefore, it is not possible for the lower ends of the ladder to be up to 12 feet apart.

The value of the expression (x³+16) ÷4 is equal to 12. The correct option is B.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is (x³+16) ÷4. The value of x is equal to 2. The expression will be solved as below,
E = (x³+16) / 4
E = 2³ + 16 / 4
E = 8 + 16 / 4
E = 8 + 4
E = 12

Answer:
y=3x+10
Step-by-step explanation:
When two lines are parallel they are going to have the same slope which is 3x. The only thing we need to find is the y intercept based on the point they say the equation passes. to do this you take away the y intercept of the equation that we have and replace x with -2 and the subtract 4 to the side with the y.. now we have 4-y=-6 Then we solve for y and get y=10 which is the y intercept of the equation that is parallel to y=3x=1 and it passes (-2,4) Therefore the answer is y=3x+10
What is the distance between the points? Round to the nearest 10th if necessary
Answer:
5\sqrt(5) or about 11.2
Step-by-step explanation:
The change in x is 5, the change is y is 10.
Using the pythagorean theorem, the distance is
\sqrt(25+100) = \sqrt(125) = 5\sqrt(5) or 11.2

A submarine travels 6.6 km due West from its base and then turns and travels due South for 3.9
km.
How far away is the submarine from its base?
Give your answer rounded to 1 DP.
Answer:
[tex]7.7[/tex] km
Step-by-step explanation:
The submarine's path from its base forms a right triangle when its final position is "connected" to the base. We know that the right triangle has legs of [tex]6.6[/tex] km and [tex]3.9[/tex] km, and we need to find the length of its hypotenuse. To do so, we can use the Pythagorean Theorem, which states that in a right triangle, [tex]a^{2}+b^{2} =c^{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the lengths of the triangle's legs and [tex]c[/tex] is the length of the triangle's hypotenuse. In this case, we know what [tex]a[/tex] and [tex]b[/tex] are, and we need to solve for c, so after substituting the given values of [tex]a[/tex] and [tex]b[/tex] into [tex]a^{2}+b^{2} =c^{2}[/tex] to solve for c, we get:
[tex]a^{2}+b^{2} =c^{2}[/tex]
[tex]6.6^{2} +3.9^{2} =c^{2}[/tex] (Substitute [tex]a=6.6[/tex] and [tex]b=3.9[/tex] into the equation)
[tex]43.56+15.21=c^{2}[/tex] (Evaluate the squares on the LHS)
[tex]58.77=c^{2}[/tex] (Simplify the LHS)
[tex]c^{2}=58.77[/tex] (Symmetric Property of Equality)
[tex]\sqrt{c^{2} } =\sqrt{58.77}[/tex] (Take the square root of both sides of the equation)
[tex]c=7.7,c=-7.7[/tex] (Simplify)
[tex]c=-7.7[/tex] is an extraneous solution because you can't have negative distance, if that makes sense, so therefore, the submarine is approximately [tex]7.7[/tex] km away from its base. Hope this helps!
