If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.
Answer:
| 4x - 6 | = - 6
Step-by-step explanation:
The absolute value function always produces a positive value.
| 4x - 6 | = - 6 ← negative value is not possible
X + 367 = 860
x = 860 - 367
x = 493
The dog had 493 bones to start with.
If Lopez's mailing bill continues to deduct 19$ from his bank account every month for a year, then in total, the deductions total for the year would be $228.00.
Why?
$19.00 is being taken away each month. There are 12 months in a year.
$19.00 x 12 months = the total of $228.00 a year.
Answer:
The cost of renting will be the same for 200 miles.
Step-by-step explanation:
Let n the number of miles and C be the cost. We can represent the cost equations for each companies:
A: C = 12 + 0.09n
B: C = 8 + 0.11n
They want to know when the cost will be the same, so we can set the above 2 equations equal to each other and solve for n:
12 + 0.09n = 8 + 0.11n
0.02n = 4
n = 200
