Answer:
18,0
Step-by-step explanation:
By useing desmos, the line has an x intercept of 18 making that the answer.
<h2>
y = 4x - 4</h2>
y = mx + c
First find the gradient.
6 - 2 = 4
Your gradient, m, is 4x.
Now find the constant, c.
y = mx + c
<u>if y = 4 and x = 2</u>
<u />
4 = 4 * 2 + c
4 = 8 + c
4 = 8 - 4
c = -4
<h2>
y = 4x - 4</h2><h2>
</h2>
You can check it's right by substituting the other values.
y = 4x - 4
E.G
36 = 4 * 10 - 4
36 = 40 - 4
The scale factor for area is the square of the scale factor for linear dimensions. If linear dimensions are scaled up by a factor of 10, the area is scaled up by a factor of 10² = 100.
The area of the larger box is 100×432 cm² = 43,200 cm².
If u are looking for x its 4 because if y=2 then u substitue it for y and you get -x+2=-2. to get x by its self you have to subtract 2 from both sides and u end up with -x=-4 and u have to divide -x by -1 to get rid of the negative and u get x=4
