Y= 9.2

Explanation:
13(y+7)=3(y-1)

Distribute the 13 on the left side and the 3 on the right side.

13y+91=3y-1

Subtract the 3y to the 13y (little brother goes to the big brother always)

10y+91=-1

Subtract 91 to the right side.

10y=92

Divide by 10.

Which graph represents y−4=2(x−3) ?

lina2011 [118]

First put the equation in point slope form:
y - 4 = 2x - 6
y = 2x - 2
Then graph this, which will look like this

Please help, very confused!

My name is Ann [436]

$\bf cot(\theta)=\cfrac{1}{tan(\theta)}
\qquad \qquad 
csc(\theta)=\cfrac{1}{sin(\theta)}\qquad \qquad sin(-\theta )=-sin(\theta )
\\\\\\
\textit{also recall }sin^2(\theta)+cos^2(\theta)=1\implies sin^2(\theta)=1-cos^2(\theta)\\\\
-------------------------------$

$\bf \cfrac{csc^2(x)-cot^2(x)}{sin(-x)cot(x)}\implies \cfrac{\frac{1}{sin^2(x)}-\frac{cos^2(x)}{sin^2(x)}}{-sin(x)\frac{cos(x)}{sin(x)}}\implies \cfrac{\frac{1-cos^2(x)}{sin^2(x)}}{-cos(x)}
\\\\\\
\cfrac{\frac{sin^2(x)}{sin^2(x)}}{-cos(x)}\implies \cfrac{1}{-cos(x)}\implies -sec(x)$

I believe it’s 82

8x=3x+8+4x+10
x=18

HELP! I NEED MATH HELP!

valkas [14]

Answer choice B is most correct. For answer a, there would be less visitors the more it rains. For b, the more the item costs, the more sales tax you pay. For answer c, the more people seated at a table, the less space per person. And for answer d, the more cats, the less mice there would be.

Let f(x)=3x-6 and g(x)=x-2 find f(g(5))-ie. (f • g)(5) and its domain

Molodets [167]

Solution for f(g(5)):

The notation f(g(5)) or (f • g)(5) means that we first plug 5 into the function g(x), simplify, then plug the answer that we got to f(x). We will do this step-by-step:

Step 1: Plugging 5 to g(x)

$g(5)=5-2=3$

Step 2: Plugging the answer to f(x)

$f(3)=3(3)-6=9-6=3$

ANSWER: f(g(5)) is equal to 3.

Domain:

For the function f(g(x)), we can find the domain by analyzing the domains of each individual functions separately and excluding certain values depending on the restrictions from the outermost function.

However, since both functions have all real numbers as its domain, we will not need to do any exclusion anymore.

ANSWER: The domain of the function is all real numbers.
