Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 2 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = , thus
y = x + c ← is the partial equation of the perpendicular line
To find c substitute (- 12, 7) into the partial equation
7 = - 16 + c ⇒ c = 7 + 16 = 23
y = x + 23 → D
Answer:
5/2y - 8
Step-by-step explanation:
Step 1: Add -7 to both sides.
2x+7+−7=5y−9+−72x=5y−16
Step 2: Divide both sides by 2.
2x2=5y−162x=52y−8
Answer:
<em>Maya needs 33 bags</em>
Step-by-step explanation:
Let's call x the number of bags of soil. If each bag contains 1.5 cubic feet, then "x" bags do not contain a volume of:
1.5x.
As a volume of 4.5 cubic feet has been published.
We need 54 cubic feet.
Then
Now we must solve the equation for x.
