<u>ANSWER</u>
C) 4x-3y=-12
<u>EXPLANATION</u>
The intercept form of a straight line is given by:
From the the x-intercept is -3 and the y-intercept is 4.
This is because each box is one unit each.
We substitute the intercepts to get:
We now multiply through by -12 to get
The correct choice is C.
The graph that best corresponds to the situation is graph 4; option C
<h3>Time graph</h3>
- Assume, the first hour, Ernie read just 2 pages
- Second hour, 5 pages
- Third hour, 7 pages
- Fourth hour, 10 pages
Number of pages read is on the y - axis
Time taken is on the x - axis
Therefore, graph 4 represent the situation

Answer: 73.50
Step-by-step explanation:
I am assuming that the new price is 36.75
50% is 1/2
36.75·2=original price
original price=73.50
Answer:
Simplest form = 4<em>z </em>+ 21
Case 1: True, Case II: false and Case III: true
Step-by-step explanation:
18<em>z </em>- 7( -3 + 2z)
= 18<em>z</em> + 21 - 14z
= 18<em>z</em> -14z + 21
= 4<em>z </em>+ 21
So, in the above expression we have two terms. First term is 4z and second term is 21.
So the first case is true. As the expression has two terms.
The coefficient of <em>z </em>is a number which is multiplied by <em>z</em>. Therefore, Second case is false as the coefficient of <em>z</em> is 4.
The constant is a number which is not multiplied by any variable. Therefore, third case is true as the constant number in above expression is 21.
