Answer:
-22/3 =x
Step-by-step explanation:
(4x-4) /(x+4) = 10
Multiply each side by (x+4)
(4x-4) /(x+4) * (x+4) = 10 * (x+4)
(4x-4) = 10 * (x+4)
Distribute
4x-4 = 10x+40
Subtract 4x from each side
4x-4-4x = 10-4x+40
-4 = 6x+40
subtract 40 from each side
-4 -40 = 6x+40-40
-44 = 6x
Divide each side by 6
-44/6 = -6x/6
-22/3 =x

If Gina has $90 and pays:
$20 for beginning
$5 per hour
Then 90 - 20 is 70. 70 divided by 5 is 14.

Answer:
Step-by-step explanation:
Given
Perpendicular to
Pass through
Required
Determine the line equation
First, we need to determine the slope of
An equation is of the form:
Where
In this case:
Next, we determine the slope of the second line.
Since both lines are perpendicular, the second line has a slope of:
Since this line passes through (-2,2); The equation is calculated as thus:
Where
This gives:
Add 2 to both sides
Answer:
The distance between the two points is
Step-by-step explanation:
The formula of the distance between two points (x1, y1) and (x2, y2) is
d =
∵ The points are (-1, 3) and (4, 2)
∴ x1 = -1 and x2 = 4
∴ y1 = 3 and y2 = 2
→ Substitute them in the formula of the distance above
∵ d =
∴ d =
∴ d =
∴ d =
∴ d =
∴ The distance between the two points is
