Well, the standard equation is in the form:

ax + bx = c (constant).

Thus, x and b must be isolated together on one side with the constant on the other. The equation which satisfies this is:

A. -2x + y = 5

Which expression correctly states that XY is congruent to VW?
monitta
We are given to lines XY and VW. Now we need to determine the expression that correctly states that these lines are congruent. One possibility to prove that they're congruent is if they are two separate lines and:

XA is congruent to VB,
AY is congruent to BW
XA + AY = XY
VB + BW = VW

Then we can conclude that if the statements above are true, XY and VW must be congruent to each other. 

Another possibility is that they are two sides of an isosceles rectangle XYVW and are opposite sides of the rectangle. <span />

1. determine if the functions are inverse functions
kirill115 [55]

Answer:

<u>Question 1</u>

The function f(x) = x + 6 is one-to-one, so it does have an inverse.

The inverse of +6 is -6, so f^{-1}(x)=x-6

Therefore, g(x) is the inverse of f(x).

<u>Question 2</u>

The function f(x) = -3x -9 is one-to-one, so it does have an inverse.

To find the inverse, replace f(x) with y:

\implies y = -3x -9

Rearrange the equation to make x the subject:

\implies y+9= -3x

\implies x=-\dfrac13(y+9)

\implies x=-\dfrac13y-3

Replace x with f^{-1}(x) and y with x:

\implies f^{-1}(x)=-\dfrac13x-3

Therefore, g(x) is the inverse of f(x).

Alexis is making cookies. The recipe says that she has to mix 192 grams of sugar into the flour. Alexis knows that 1 cup of this
Dmitrij [34]
For this case we can make the following rule of three:
 1 cup ----------------> 128 grams
 x ----------------------> 192 grams
 From here, we clear the value of x.
 We have then:
 x = (192/128) * (1)
 x = 1.5
 x = 1 1/2
 Answer:
 
She needs about 1 1/2 cups.

1. We can use division to solve real life problems, such as:
iren2701 [21]
Well, let's look at the answer choices.
A) If you want to fond the total cost of two sweaters you would add, not divide. So this isn't it.
B) To find out how much older someone is you would subtract. So this isn't it either.
C) To find out how many desks are needed you would multiply, since you know you need 3 rows of desks with 7 students each (3 x 7). Again, not it.
D) To find out how many pencils each student would get, you'd divide. You would divide 56 by 9. So your answer is D.
