Answer:
x = 2
y = -3
Step-by-step explanation:
y = x - 5 -------------------(I)
x + y = -1 ----------------(II)
Substitute y = x -5 in equation (II)
x + (x - 5) = -1
x + x - 5 = -1 {Combine like terms}
2x - 5 = -1 {Add 5 to both sides}
2x = -1 + 5
2x = 4 {Divide both sides by 2}
x = 4/2
x = 2
Substitute x = 2 in equation (I)
y = 2 - 5
y = -3
Answer:
4240 inches²
Step-by-step explanation:
In order to find the amount of film needed, we have to find the surface area of this cuboid.
- Formula to Find Surface Area of Cuboid:
, where w = width, l = length, and h = height.
Now, let's solve!
Therefore, the answer is 4240 inches².
ANSWER:
4th option: y = cosine (x + pi)
STEP-BY-STEP EXPLANATION:
For the function y = cosine (x), when x = 0, y = 1 and when x = , y = -1. The graph shows the opposite, when x = 0, y = -1 and when x = , y = 1, so we must add the same amount x = , for y to be positive 1.
So the equation of the graph would be:

The correct answer is then the 4th option y = cosine (x + pi)
The point-slope form:

We have the slope m = 3 and the point (-1, 5). Substitute:

<em>use distributive property</em>
<em>add 5 to both sides</em>
- slope-intercept form
