Answer: 38

Step-by-step explanation: this is a 90 degree angle and 90-52= 38

Answer:

a = 3, b = 2

Step-by-step explanation:

It is given that both the polynomials are equal.

Therefore, h(x) = k(x)

[tex] {x}^{3} + (a + b) {x}^{2} - 4x + 2 \\ = {x}^{3} + 5 {x}^{2} - (2a - b)x + 2 \\ \\ equating \: like \: terms \: on \: both \: sides \\ (a + b) {x}^{2} = 5 {x}^{2} \\ \implies \: a + b = 5.....(1) \\ \\ - (2a - b)x = - 4x \\ 2a - b = 4....(2) \\ \\ adding \: equations \: (1) \: and \: (2) \\ \\ 3a = 9 \\ \implies \: a = \frac{9}{3} \\ \huge \red{ \boxed{\implies \: a = 3}} \\ \\ substituting \: a = 3 \: in \: equation \: (1) \\ 3 + b = 5 \\ \implies \: b = 5 - 3 \\ \huge \purple{ \boxed{ \implies b = 2}}[/tex]

Answer:

12h+20=M

Where H=hours babysitting and M= money made or total amount

in this case since it's only an hour the equation would be 12(1)+20=M

12*1=12 and 12+20=32 so in the one hour with homework help would give you 32=M just for one hour.

Note that the 20 never changes considering it's only the charge for helping with homework and not over an hour.

But since this only asked for an hour and never specified if it was with the homework help here's this

12h=M

Answer: Percentage of female workers = 40%

Step-by-step explanation: No of Female workers = 80

                                             No of Male workers = 120

                                             Total No of workers = 120+80= 200

                                             percentage of female workers =80 of 200%= 40

The simplified form of the expression is 8.3y + 3.1

Given the following equations

(8-0.2+0.5)y + (2.2+1.3 - 0.4)

First is to Reorder the expression to have:

(8+0.5-0.2)y + (2.2+1.3 - 0.4)

Group the resulting expression

[8.5-0.2]y + (3.5 - 0.4)

Simplify the result

8.3y + 3.1

Hence the simplified form of the expression is 8.3y + 3.1

Answer:

9 inches and 4 inches

Answer:

Option A

Step-by-step explanation:

Given the following question:

[tex]A=w\times h[/tex]

To find the answer we substitute the values of each option in till we find the answer that doesn't equal 36 square units, since the question already gives us the area of the rectangle.

Option A:
[tex]A=w\times h[/tex]
[tex]A=4\times8[/tex]
[tex]4\times8=32[/tex]
[tex]=32[/tex]

Answer:

6x+1

Step-by-step explanation:

Answer:

6x+1

Step-by-step explanation:

Hi there!

We are given the following expression:
4x + 8 + 2x - 7

And we want to simplify

When we simplify, we want to combine like terms. This means that we want to add terms with the same variables together (like x), and then combine them  

If there is no variable, then we add and combine the terms that don't have any variable together as well

Please note that we cannot combine terms with different variables (so if you had x+y, then it would stay as x+y).

In this case, we have 4x + 8 + 2x - 7

4x and 2x are like terms; they have the same variable (x). If we add them together, the result is 6x

8 and -7 are also like terms; they both don't have a variable. If we add (or rather, subtract) these terms, the result is 1.

Now we add 6x and 1 together, which would be 6x+1 (1 doesn't have a variable after it, so we can't combine it with 6x).

6x+1 is our answer.

Hope this helps!

Step-by-step explanation:

D and E are right.

==================================================

Explanation:

The domain is the set of all real numbers because we can replace x with any real number we want to get some y output. There isn't any restriction on x. We don't have to worry about dividing by zero for instance. This is why choice A is one of the answers.

The range is restricted however. The largest value we can make in the range is y = 0. The graph of y = -4x^2 shows a parabola that opens upside down. The highest point is at (0,0). So that's why choice D is the other answer.
