Answer:

600 i believe

Step-by-step explanation: I plugged this into my calculator

Answer:

600

Step-by-step explanation:

Always do what is the parentheses first so -12*5= -60

Then multiply -10 and -60

A negative and a negative equal a positive

10 times 60 is 600

I hope this helps :)

Answer:

-100

Step-by-step explanation:

8*-100=-800

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.

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

Answer:

1/2

Step-by-step explanation:

9/6 x 3

First, multiply 6 and 3 together

9/18

We can simplify this fraction by dividing the numerator and denominator by 9

1/2

I Hope That This Helps! :)

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:

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.

I hope that this helps! :)

Answer:

11.02-9.91= 1.11

Step-by-step explanation:

|-11.02| - |-9.91| (First solve in absolute)

11.02 - 9.91 (any values outside absolute becomes positive)

1.11

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:

first and third

Step-by-step explanation: just took the test like 5 secs ago

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:

1120000 attendees

Step-by-step explanation:

Given that:

Yearly Average attendance = 2.8 * 10^5 people

How many attendees can be expected to attend over 4 years

Average Yearly attendees * 4

(2.8 * 10^5) * 4

= 2.8 * 4 * 10^5

= 11.2 * 10^5

= 1120000 attendees

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

Step-by-step explanation:

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: 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]
