Help please it math!!!!

Answer: Choice D) [tex]y = \pm \sqrt{x+5}[/tex]

The steps to finding the inverse will have us swap x and y. Afterward, we solve for y

[tex]y = x^2 - 5 \\\\x = y^2 - 5 \\\\x+5 = y^2 \\\\y^2 = x+5 \\\\y = \pm \sqrt{x+5} \\\\[/tex]

------------------------------

Extra info:

The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into [tex]y = \pm \sqrt{x+5}[/tex] leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on [tex]y = x^2-5[/tex] to make it a one-to-one function, to make the inverse a function. One possible domain restriction is [tex]x > 0[/tex] which would lead to the inverse function [tex]y = \sqrt{x+5}[/tex]

Answer:

B.) -4

Step-by-step explanation:

y=mx+b

b is equal to the y-intercept.

Answer:

-4

Step-by-step explanation:

The slope intercept form is y = mx + b.

m = slope

b = y-intercept

since b = -4, the y-intercept is -4

Answer:

the answer to your question is y = -30

Answer:

-30

-Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1/2y+5=-10

Step 2: Subtract 5 from both sides.

1/2y+5-5=-10-5

1/2y+-15

Step 3: Multiply both sides by 2.

2*(1/2y)=(2)*(-15)

y=-30

Hope this helpss,good luck w thisss

Answer:

-28

Step-by-step explanation:

First one

1. XW≅ZW        1. Given     It's good to start with given

2.∠XWY ≅ ∠ZWY  2. Given     Again, get the given out of the way

3.WY ≅ WY    3.  Reflexive        This reason basically means that the line is equal to itself

4.ΔXWY ≅ZWY 4.  SAS                  We have a side, an angle and a side: SAS

Second Problem

Again, let's get the givens out of the way. I'm lazy, so just put the things in the given section in the boxes.

3. Vertical angles             This is just a fun way of saying that the angles on top of each other are equal

4. AAS                                We have an angle, an angle and a side. Whack em' together and you get AAS

this should be ok by now lmk if its not.

Answer:

24

Step-by-step explanation:

If f is equal to 7, you'd multiply 7 by 2 (following pemdas/gemdas). When you multiply those two numbers, you get 14. If you add 8 to 14 you get 24.

Answer:

First and third relations represent functions.

Step-by-step explanation:

First and third relations are one-to-one and many-to-one respectively, therefore these are functions.

Second and fourth relations are one - to - many, thus they are not functions.

Answer:

-44

Step-by-step explanation:   -44

Given:

Company profits = $28,000

Charity = $4200

To find:

The percent that will the company give to charity.

Solution:

We have,

Company profits = $28,000

Charity = $4200

Now,

[tex]Charity\%=\dfrac{Charity}{Profit}\times 100[/tex]

[tex]Charity\%=\dfrac{4200}{28000}\times 100[/tex]

[tex]Charity\%=\dfrac{420}{28}\times 1[/tex]

[tex]Charity\%=15\%[/tex]

Therefore, the company will give 15% of its profit to charity.

Answer:

14x + 1

Step-by-step explanation:

4(2x-1)+3(2x+5) = 2x*4 - 1*4  + 2x*3 + 5*3

                          = 8x - 4 + 6x + 5

                          = 8x + 6x -4 + 5  {Combine like terms}

                          = 14x + 1

Answer:

D. identity

Step-by-step explanation:

- 6a + 3 = - 3(2a - 1)

First, distribute -3 within the parenthesis.

- 6a + 3 = - 6a + 3

Subtract 3 from both sides of the equation

- 6a = - 6a

Divide - 6 on both sides of the equation

a = a

We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity

For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.

The value that completes the square is: c=8

Step-by-step explanation:

Find the value of c that completes the square  [tex]x^2-16x+c[/tex]

The formula used is: [tex]a^2-2ab+b^2=(a-b)^2[/tex]

In the question given the value c can be found by breaking the middle term. we are given -16x while the general formula is 2ab for middle term so,

2(x)(8) = 16x

so, c= 8

Solving:

[tex]x^2-16x+c\\=x^2-2(x)(8)+(8)^2-(8)^2\\=(x-8)^2-64[/tex]

So, the value that completes the square is: c=8

Step-by-step explanation:

m= -7 and b= 6

equation equals -13

Answer:

ok the slope is -1/2

the points I used where (-6,-1) and (-2,-3)

the intercept of y is -4

the equation is 2y +x+8=0

Step-by-step explanation:

using the formula y2- y1 = m

X2-X1

where m is the gradient, the slope is found

the original equation is y=-1/2x-4

and so if x is zero ( to get the y intercept)

y=-4

using the formula y - y1= m( x -x1 )

, the equation is determined

Actually Welcome to the Concept of the Ratio and Proportions.

Thus the equivalent ratio to 8:5 will be,

24:15 , 40:25 and 16:10

because, here if we reduce by common multiple 24:15 , 40:25 and 16:10 both , we will get as 8:5

so the correct answer is c.) 40:25 and e.) 16:10 b.) 24:15

Select all ratios equivalent to 1:2
