Answer:
f(x)=5(2)^x
Step-by-step explanation:
So the 0 value is five it is going up by 2 to the power of x,
STEP 1:
Sale Price= Cost - (Cost * Discount %)
Sale Price= $80 - (80 * 10%)
=80 - 8
=$72 sale price
STEP 2:
use sale price from step 1 in this equation
Final Price= Cost + (Cost * Tax %)
Final Price= $72 + (72 * 7%)

Which is the Origin
Answer:
Step-by-step explanation:
The slope-intercept form of the equation of a line is:
Where m is the slope of the line and b is the intercept with the y axis.
So:
To find b we take the point (1970, 23.2) and introduce it in the previous equation.
Then the equation is:
Answer: y= 2x-8
Step-by-step explanation:
2y-4x=-16
2y=-16+4x
y=-8+2x
y= 2x-8
