-25 - 12x = -(-8x - 6) - 3(5x + 12)

Distributive property.

-25 - 12x = 8x + 6 - 15x - 36

Combine like terms.

-25 - 12x = -7x - 30

Add 12x to both sides.

-25 = 5x - 30

Add 30 to both sides.

5 = 5x

Divide both sides by 5.

x = 1

The x-intersect is 1.

In the slope intercept equation of a line which quantity is given by the constant term

ankoles [38]

The slope intercept form is y = mx + c.

The quantity given by the constant term c, is the vertical or y intercept.

It is the point where the line cuts the y axis, and this point, x = 0.

HELP!!!! PLEASE I NEED HELP!!!!

NNADVOKAT [17]

for the first one it is the second option because of one property of logarithms:

log(a)-log(b)=log $\frac{a}{b}$

for the second one using the same property we can say that we third option is correct and not the second one but we use one more property of the logarithm

loga(b)^x=xloga(b) the power of the logarithm becomes a fator and $\sqrt[3]{x}$ is equal to $x^{\frac{1}{3}}$

Arada [10]

Answer:

A. No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means.

Step-by-step explanation:

No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means. The central limit theorem says that if we take a large sample (i.e., a sample of size n > 30) of any distribution with finite mean $\mu$ and standard deviation $\sigma$ , then, the sample average is approximately normally distributed with mean $\mu$ and variance $\sigma^2/n$ .
