Answer:
603
Step-by-step explanation:
First divide to get unit rate:
737/11= 67
Then multiply:
67*9= 603
Hope this helps! :)
Answer:
Scott would drive 603 miles in 9 hours
Step-by-step explanation:
First to find the rate we need to see how many miles Scott can drive per hour.
737/11=67
67/1 or 67 mph is our unit rate.
so if we want to know how many miles he can drive per 9 miles we just multiply (the unite rate by how many miles) 67 x 9, which equals, 603.

Gracie has six dollars to buy a gallon of milk and some apples. The gallon of milk cost $3.59 and the apples cost $.60 each. Which any inequality could she use to find out how many apples she can buy?
Answers
Answer: 4
Step-by-step explanation:
Let the number of gallon milk cartons be M and the number of apples be N. The total cost would be 3.59M + 0.60N <= 6.00. If M = 1, then
3.59 + 0.60N <= 6.00
0.60N <= 2.41
N <= 4 [2.40, with 0.01 left over]

Which equation represents the line that passes through the points (-3;7) and (9,-1)
Answers
Answer:
[tex]y = - \frac{2}{3} x + 5[/tex]
Step-by-step explanation:
[tex]y = mx + b[/tex]
finding the slope m of the line using the above points
[tex] m = \frac{y2 - y1}{x2 - x1} = \\ \frac{ - 1 - 7}{9 - - 3} = \frac{ - 8}{9 + 3} = - \frac{8}{12} = - \frac{2}{3} [/tex]
substitute the slope and one of the points into the y-intercept form to solve for b
[tex]y = mx + b \\ 7 = - \frac{2}{3} ( - 3) + b \\ 7 = \frac{6}{3} + b \\ 7 - 2 = b \\ b = 5[/tex]
therefore the answer to the question is
[tex]y = - \frac{2}{3} x + 5[/tex]

Step-by-step explanation:
In order to find the answer to this question you need to input the values in a slope formula and solve using KCF (Keep, Change, Flip) if needed.
[tex]m = \frac{y^2-y^1}{x^2-x^1}[/tex]
[tex](-3,-1),(2,-1)[/tex]
[tex](x^1,y^1)=(-3,-1)[/tex]
[tex](x^2,y^2)=(2,-1)[/tex]
Substitute:
[tex]m=\frac{-1--1}{2--3}[/tex]
Solve using KCF:
[tex]-1+1=0[/tex]
[tex]2+3=5[/tex]

. Let g(x) = 3x2 + 4X – 36. What is g(2)?
Answers
Answer:
Step-by-step explanation:
The notation means that wherever you see an x on the right, you let it equal 2.
g(x) = 3x^2 + 4x - 36
x = 2
g(2) = 3*2^2 + 4*2 - 36
g(2) = 3*4 + 8 - 36
g(2) = 12 + 8 - 36
g(2) = 20 - 36
g(2) = - 16
