Answer:
5(7 - x).
Step-by-step explanation:
That is 5 multiplied by 7 - x where x is the number.
Slope intercept form
y=mx+b
m=slope
b=yintercept
slope for the line passing through the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(2,-2) and (2,-3)
slope=(-3-(-2))/(2-2)=(-1)/0=undefined
y=undefinedx
this means that the equation is x=something
we see
(x,y)
(2,-2)
(2,-3)
x=2 is the equation
we cannot write it in slope intercept form
-8x - 46 = -6x - 8
-8x + 6x = -8 + 46
-2x = 38
x = -19
The equation:
-8x - 46 = -6x - 8
The solution:
x = -19
Answer:
He can go 10.78 miles
Step-by-step explanation:
This problem can be solve by creating a proportion, knowing that 15.4 miles is to one gallon the same as "x" miles (our unknown) is to 0.7 gallons. This can be set in math terms as the equation that relates these two ratios of miles per gallon:
and to solve for the unknown number of mile, we multiply both sides of the equation by "0.7 gallon" in order to isolate our unknown:
