Answer:
y=-2x+2
slope-intercept form --> y=mx+b
m= slope. the slope in the graph is down 2 over 1, -2/1 which is the same as -2.
b = <u>y-intercept</u><u>. </u><u> </u><u>the </u><u>y-intercept</u><u> </u><u>is </u><u>2</u><u>.</u>
It's D. Slopes are the same, because if you divide opposite and adjacent side of both triangles, you get the same result. Count the squares, for the smaller triangle it's 2/2=1 and for the bigger one it's 4/4=1.
It is B.Scale factor=New length/old length=8/2=4
Answer:
Step-by-step explanation:
Assuming that for each option, you play the same number of games,x
Let y represent the cost of playing x games using option A
Option A is to buy a membership card and pay $2 every time you go to the gym. The membership card costs $20. It means that
y = 20 + 2x
Let z represent the cost of playing x games using option B
Option B is to pay $4 each time you go. It means that
z = 4x
To determine how many games will be played before cost of option A equal to the cost of option B, we would equate y to z. It becomes
20 + 2x = 4x
4x - 2x = 20
2x = 20
x = 20/2 = 10
It will take 10 games for both to be the same
Answer:
5398
Step-by-step explanation:
7715-2212+10-(5x23)
7715-2212+10-115
