What is the solution to the system of equations 2x-y=7
y=2x+3

a. (2,3)
b.(2,7)
c. no solution
d. infinite number of solutions

the answer is C. no solution

Step-by-step explanation:

2x-y=7

y=2x+3

2x-(2x+3)=7

no solution

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
