Answer is x=4. Multiply by 5 on each side to cancel out the denominator.
5x-35=-3x-3
Add 3x and 35 to each side
5x + 3x = -3 + 35
8x = 32
Divide both by 8
X = 4

Multiply (FOIL) ( x - 3)( 2x + 5) (3x + 7)(2x - 1)

Troyanec [42]

$(x-3)(2x+5)=2x^2+5x-6x-15=\boxed{2x^2-x-15}\\\\(3x+7)(2x-1)=6x^2-3x+14x-7=\boxed{6x^2+11x-7}$

I need help with problem number 3 if someone can help me with that

Plug in x into the equation. Take x= -2 for example. Your equation is 2x-5, so instead of x, you put -2.
2(-2)-5 = -9
Your table is as follows:
(-2,-9)
(-1,-7)
(0,-5)
(1,-3)

The results of a linear regression are shown below.

IgorLugansk [536]

Hello!

As we can see, our a value, which would be the coefficient of $x$ , which determines our slope, is negative, meaning that this whole line is negative.

Furthermore, the correlation can be determined using the r value of the linear regression, which is around -0.9.

If the r value of the linear regression is close to 1 or -1, let's say around |r| > 0.8, then we can consider the regression a strong correlation, meaning that this is a strong negative correlation, which is answer choice A.
