Answer:
Step-by-step explanation:
(3,−1) (4,7)
Slope = y₂-y₁/x₂-x₁
= 7- [-1]/4-3
=7+1/1 = 8/1
= 8
m = 8 ; (4,7)
y-y₁= m(x-x₁)
y - 7 = 8 * (x - 4)
y -7 = 8x - 32
y = 8x - 32 + 7
y = 8x - 25
Answer:
x=-8 ,2
Step-by-step explanation:
x ^ 2 + 6x - 6 = 10
Add 6 to each side
x ^ 2 + 6x - 6+6 = 10+6
x ^ 2 + 6x = 16
Complete the square take the coefficient of the x terms, divide by 2 and square it. Then add it to each side
6/2 =3 , 3^2 =9
x ^ 2 + 6x +9 = 16+9
(x+3)^2 = 25
Take the square root of each side
sqrt((x+3)^2) = ±sqrt(25)
x+3= ±5
Make 2 equations
x+3 = 5 x+3 = -5
Subtract 3 from each side
x+3-3 =5-3 x+3-3 = -5-3
x =2 x=-8
It easiest to like take the percentages from each answer choice.
d would be the answer because 40% (25%+15%) of $97.39 is abt $57.37
We are given the function:
g(n) =

We need to find what g(-3) equals.
What the question is asking is what is the resulting value after you plug in -3 as n to the function. Meaning you replace the n that is in the function with -3.
g(-3) =

Remember back to the order of operations.
Parenthesis

For this problem we can keep the fraction as it is (unless you are permitted to use a calculator... if that is the case then just plug all that into a calculator) and keep going to the exponent.
Negative exponents make fractions FLIP. So our fraction will look like this:

Now that we have it without the negative exponent we need to distribute the cubed power to each number in the fraction (which is essentially the same as saying this:

)

We ARE NOT done! We still have this left:
g(-3) =

Multiplying by 3 you get the following:

So what does g(-3) equal? This right here:
I don’t have a calculator with me use sine 20divided by Sin(60) will give you x
