Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~~~~~
-4x + 5x = -40
y = -4x +5x + 40
y = x + 40
~~~~~~~~~~~~~~~~~~~~~~~~~~
by the look of it, after you turn that equation into slope-intercept form (y = mx + b) the intercepts are y = 40 & x = -40
In this problem you use cosine because you know the hypotenuse and you want to know the adjacent side of the triangle. So in your calculator you would input cos(52). Then you would multiply that answer with the hypotenuse side. So your equation would be this: cos(52) x 13
Answer:
y=3
Step-by-step explanation:
it is because X=-2 had crossed the point y=3
hope this help you!!!! ;))))))
The correct answer is -1.
In order to solve this, we need to split into the positive and negative version of the answers. Let's start with the positive version.
2 - x < 4
-x < 2
x > -2 ----> NOTE: When we divide by -1, we have to change the direction of the sign.
Now we'll do the negative version.
2 - x > -4
-x > -6
x < 6
So we know the number must be greater than -2, but less than 6. The only number on this list that fits that is -1.
