Answer:
A
Step-by-step explanation:
A. x = 25
Fill in the y of the bottom equation with the top equation because it gives you what Y equals. To answer the question it would be easier to input the top equation into the bottom one. Once you then get the equation for X go to the equation on top and fill in the x to get the y. X=0 Y=2
Answer:

Step-by-step explanation:
The reason is because you don't know the Inital amount she bought and because she visits two days in a row you would multiply
Answer:
y = 2x+1 (slope-intercept form)
Step-by-step explanation:
From line B, y = 2x -2 and comparing with the general equation of line, y = mx +c, we have
m1 = 2
Parallelism rule states that m1=m2
Therefore, m2 = 2
Hence, the equation passing through point A(1,3) is
y-y1 = m2(x-X1)
y - 3 = 2(x-1)
y-3 = 2x-2
y = 2x-2+3
y = 2x+1 (slope-intercept form)
