To model 32%, you would just color in 32 out of 100 blocks. It represents the ratio because out of 100 blocks, 32 are shaded.
Answer:
C
Step-by-step explanation:
Plug in -3 for x: y = -(-3)²+3 = -9+3 = -6 (-3,-6)
plug in 0 for x: y = =(0)² + 3 = 3 (0,3)
plug in 3 for x: y = -(3)² + 3 = -9+3 = -3 (3, -6)
Answer:
y = - 3x + 17
Step-by-step explanation:
Note that slope is a measure of the rate of change of a linear function.
Express the function in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (5, 2) into the partial function
2 = - 15 + c ⇒ c = 2 + 15 = 17
y = - 3x + 17 ← is the linear function
Answer:
8 dollars
Step-by-step explanation:
if "x" is his weekly allowance:
x-0.5x+8=12
Dan make x dollars, then he spend 0.5x dollars and he earned 8 dollars, and that is 12 dollars.
0.5x=12-8
x=8 dollars
