Answer:
Yes
Step-by-step explanation:
<h3>Hank</h3>
Hank paid $2,000 upfront when he bought his car, and he pays $200 each month.
<u>
This relation is: </u>
This is proportional but not directly proportional.
<h3>Lynn</h3>
Lynn did not pay any money upfront when she bought her car, and she pays $275 each month.
<u> This relation is: </u>
This is directly proportional.
<u>So the answer is:</u>
Yes, the relationship between the number of months and the total amount paid is proportional for both Hank's and Lynn's loans.
Multiply it again so it equals that 310 number
Answer:
(2, 7 )
Step-by-step explanation:
Given the 2 equations
y = 2x + 3 → (1)
y = 3x + 1 → (2)
Substitute y = 3x + 1 into (1)
3x + 1 = 2x + 3 ( subtract 2x from both sides )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting x = 2 into (1)
y = 2(2) + 3 = 4 + 3 = 7
Solution is (2, 7 )
We have 200 calculators and x are scientific. That means (200-x) are financial.
Total cost = 89x + 599(200-x)
-3x+9y =18
add 3x to each side
9y = 3x+18
divide by 9
y = 3/9 x +18/9
y = 1/3 x+2
the slope is 1/3
the y intercept is 2
-3x+9y =18
let y=0 to find the x intercept
-3x=18
divide by -3
x=-6
the x intercept is -6
