The equation of the line of best fit is an illustration of a linear function
The teenager would spend $9 on food if he or she is at the mall for three hours.
How to determine the amount spent on food?
The equation of the line of best fit is given as:
y = 2x + 3
When the teenager spends 3 hours in the mall, it means that:
x = 3
So, we have:
y = 2 * 3 + 3
Evaluate the product
y = 6 + 3
Evaluate the sum
y = 9
Hence, the teenager would spend $9 on food if he or she is at the mall for three hours.

Sasha’s daily tips this work week were $43, $32, $65, $88, $50, and $72. Is Sasha correct in thinking that the mean accurately represents how much money she makes in daily tips? Yes, Sasha is correct. The mean amount she makes is $58. 33 in a day. Yes, Sasha is correct. The mean amount she makes is $65. 33 in a day. No, Sasha is not correct. The median amount she makes is $53. 00 in a day. No, Sasha is not correct. The median amount she makes is $60. 00 in a day.
Answer: Yes Sasha is correct she makes $58.33 a day
Step-by-step explanation: First add all the tips
[43 + 32 + 65 + 88 +50 + 72 =350]
Then divide by how many tips there are
[350 ÷ 6]
therefore your answer is $58.33

Find the value of r.
Note: Write your answer as a decimal.
Answer:
[tex]\huge\boxed{\sf r = 10.5}[/tex]
Step-by-step explanation:
Since it is a right-angled triangle, it has base, perpendicular and hypotenuse.
Base = r
Perpendicular = 14
Hypotenuse = r + 7
Using Pythagoras theorem:
[tex](Hypotenuse)^2 = (Base)^2+(Perp)^2[/tex]
Put the values
(r + 7)² = (r)² + (14)²
Using formula a² + 2ab + b² = (a + b)²
r² + 14r + 49 = r² + 196
Subtract r² to both sides
14r + 49 = 196
Subtract 49 to both sides
14r = 196 - 49
14r = 147
Divide 14 to both sides
r = 147 / 14
r = 10.5

Determine the intercepts of the line.
Do not round your answers.
y = 4x + 7
X-intercept: ( __ , __ )
Y-intercept: ( __ , __ )
Answer:
y intercept is (0,7) & x is (7/4,0)
Step-by-step explanation:
you put 0 for y or x and solve to get the intercept. for y int, you put 0 where the x is. for x int, put 0 at y.
y intercept is (0,7).
y = 4(0) + 7
y = 0 + 7
y = 7
x intercept is (7/4,0)
0 = 4x + 7
7 = 4x
7/4 = 4x/4
7/4 = x

Which sum is rational?
A. 1 + 18
B. 25 + 1.75
C. V3 + 5.5
D. I+V2
Answer: B. √25 + 1.75.
Step-by-step explanation: Rational Numbers are numbers that terminate or don't need to be terminated. For example, 1/3 is a repeating number, but we can terminate the value, whereas pi is never ending, and there is no terminating with that value. Numbers like 5.56 and 7/8 are rational because they don't need to be terminated to be rational. √25 is 5, no decimals to terminate or anything, and that makes the value rational. 1.75 is also rational, and that's why equation c is fully rational. √3 and √2 can't terminate, because both are 1.73205080757 and 1.41421356237, which means that they still can't terminate. Pi cannot terminate, so that's why the answer choices with pi aren't rational.

Write an equation for a line that passes through (1,-4) and (3,-5)
Answer:
y = -3/4x - 1/2
Step-by-step explanation:
Given:
Point 1: (1, -4)
Point 2: (3, -5)
Find:
The equation for the line that passes through Point 1 & Point 2
Solution:
y = mx + b
Will be the equation to arrive to at the very end, but we need m & b, the slope and the y-intercept
m = ( y2 - y1 ) / ( x2 - x1 ) = ( -5 - (-4) ) / ( 3 - 1 ) = -1 / 2
∴ m = - 1/2
Using either P1 or P2, plug in one of their respective x- and y-values into:
y = -1/2 x + b
I'll do (3, -5):
-5 = -1/2 ( 3 ) + b
-2 = -3/2 + b
-4 = -3 + 2b
-1 = 2b
∴ b = -1/2
∴ y = -3/4x - 1/2 is the equation of the line that passes thru both points (-5, 4) and (3, -2)

x= -5y + 36
5x + 5y = 0
The substitution method. Also please help me I’m so confused
Answer:
x = -9
y = 9
Step-by-step explanation:
If we know that x = -5y + 36
The second line says that
5x + 5y = 0
We can substiute the value of x from the first line into the second line.
So it becomes
5 ( -5y+36) + 5y = 0
Distribute the 5 over the parentheses
-25y + 180 +5y = 0
Then we can add things that are alike; so that means we can add the y values
-20y + 180 = 0
Then add 20y to both sides of the equation
180 = 20y
Then you divide by 20.
You get 9 = y!
Now that you have the value of y, you can put it back into the intial question.
5x+5y = 0
5x + 5(9) = 0
5x + 45 = 0
5x = -45
x = -9
Answer:
x=-9 y=9
Step-by-step explanation:
Substitute x:
5(-5y+36)+5y=0
Use Distributive property
-25y+180+5y=0
Add Like terms
-20y+180=0
Subtract 180 from both sides
-20y=-180
divide -20 from both sides
y=9
Solve for x by substituting the value of y into the equation x= -5y + 36
to get x=-9
what is w + 4 1/4 = 13 19/20
Answer:
w = 9 7/10
Step-by-step explanation:
w + 4 1/4 = 13 19/20
Subtract 4 1/4 from each side
w = 13 19/20 - 4 1/4
Get a common denominator of 20
w = 13 19/ 20 - 4 1/4*5/5
w = 13 19/ 20 - 4 5/20
w = 9 14/20
We can simplify
w = 9 7/10
Rewrite the fractions to have the same denominator:
1/4 can be rewritten as 5/20
now you have w + 4 5/20 = 13 19/20
Solve for w by subtracting 4 5/20 from both sides:
W = 9 14/20 which can be rewritten as 9 7/10
answer: 9 7/10
