Answer:
4.46
Step-by-step explanation:
(11.5 + x) + 5% = 16.8
11.5 + x = 16.8 - 5%
x = (16.8 - 5% ) - 11.5
x = 15.96 - 11.5
x = 4.46
Answer:
y-1 = 5(x+8)
Step-by-step explanation:
The standard equation of a line in point slope form is expressed as;
y-y0 = m(x-x0)
m is the slope
(x0, y0) is the point
Given
Slope m = 5 (assumed value)
Point (-8,1)
Substitute the given data's into the formula
y -1 = 5(x-(-8))
y-1 = 5(x+8)
Hence the required equation is y-1 = 5(x+8)
