Answer:

Step-by-step explanation:

Slope= x÷y

So. m= -2

For y intercept consider equation

y= 2x-8

y=mx+c where c is y intercept

Hence y intercept is 8 as slope is negative

Answer:

m = 2 and b = -8.

Step-by-step explanation:

One of the most commonly used equations of straight lines is y = mx + b, where m is the slope and b is the y-intercept.

Comparing the given y = 2x - 8 to y = mx + b, we see that m = 2 and b = -8.

The answer the 3,

First you have to apply the exponent rule which is 1 - 3• 1/g

Then you multiply the fractions - 1•3/g

Then multiply the numbers 1 and 3, which is 3, so there you have it 3/g, or 3, they’re the same thing.

If f(x)=2x+1 and g(x)=x^2-1, find (f/g)(x)
Debora [2.8K]

Given : f(x)=2x+1 and g(x)=x^2-1.

We need to find  (f/g)(x).

<u>Note: In the given options, we have 2x + 1 and  x^2 - 7 parts.</u>

So, let us take f(x)=2x+1 and g(x)=x^2-7.

(f/g)(x) =\frac{f(x)}{g(x)}

Plugging f and g functions in the formula.

(\frac{f}{g})(x)=\frac{(2x+1)}{(x^2-7)}

Also, it would be undefined for x = ± square root 7 becaue it would give 0 in the denomiantor.

Therefore, correct option is C. 2x + 1 / x^2 - 7, x ≠ ± square root 7.

Please help: 3(x+2)+2(x-4)=x-3(x+3)
qwelly [4]

<em>*Distribute*</em>

3x+6+2x-8=x-3x-9

<em>*Combine like terms*</em>

5x-2=-2x-9

<em>*Add 2x to both sides*</em>

7x-2=-9

<em>*Add 2 to both sides*</em>

7x=-7

<em>*Divide both sides by 7*</em>

x=-1

Hope this helps!!
