Yes!
-5 - 2 = -7;
-12 - (-5) = -7;
-19 -(-12) = -7;
-26 -(-19) = -7.
Answer:
m=2
Step-by-step explanation:
We are given a line y=mx-7 and the point lying on the given line is (3,-1) in the standard {x,y} coordinate plane.
Therefore, substituting the values of x=3 and y=-1 in the given line, we have,
⇒
⇒
⇒
⇒
⇒
Hence,the value of m will be equal to two.
The revenue when the number of units is 18 is -135
<h3>How to determine the revenue?</h3>
The given parameters are:
Revenue function
R(x) = x *P(x)
Where
P(x) = 42/(4) − x
Substitute P(x) = 42/(4) − x in the equation R(x) = x *P(x)
R(x) = x * [42/(4) − x]
The number of units sold is 18.
So, we have:
R(18) = 18 * [42/(4) − 18]
Evaluate the expression
R(18) = -135
Hence, the revenue when the number of units is 18 is -135

Answer:
First, transform the given equation into the slope-intercept form, y = mx + b.
2x - 3y < 12
3y > 2x - 12
y >
x - 4
Since the equation is y >
x - 4, first draw the graph of y =
x - 4 with a dotted line (because it is >, not ≥) and shade the area above the dotted line.
