Answer:

-2

Step-by-step explanation:

Step 1. Copy the given expression.

(a + y)^2 + 2y =

Step 2. Replace each variable by the value given.

We are given a = 5; y = -3.

= (5 + (-3))^2 + 2(-3)

Evaluate the expression using the correct order of operations.

= (2)^2 - 6

= 4 - 6

= -2

What is the equation of the line that passes through the point (4, -2) and has a <br> slope of -22
Nina [5.8K]

Answer: the answer is y=-22x+86

here is why:

the slope is -22 which is the m --> y=mx+b the point is (4,-2) the x=4 and y= =2

If we set up the equation:

-2= -22(4)+86

-2= -88+86

-2= -2

2/3 is what percent of 1/4?
saveliy_v [14]
So if we take 1/4 to be the 100%, what is 2/3 in percentage off of it then?

\bf \begin{array}{ccll}&#10;amount&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;\frac{1}{4}&100\\\\&#10;\frac{2}{3}&p&#10;\end{array}\implies \cfrac{\frac{1}{4}}{\frac{2}{3}}=\cfrac{100}{p}\implies \cfrac{1}{4}\cdot \cfrac{3}{2}=\cfrac{100}{p}\implies \cfrac{3}{8}=\cfrac{100}{p}&#10;\\\\\\&#10;p=\cfrac{8\cdot 100}{3}\implies p=\cfrac{800}{3}\implies p=266\frac{2}{3}\implies p\approx 266.\overline{66}

yes, is a large value, because 2/3 is indeed larger than 1/4, more than twice as large.

Solve for x<br> A) 42<br> B) 40<br> C) 45<br> D) 38
alexgriva [62]

Answer:

x = 40

Step-by-step explanation:

Using similarity theorem, we have the following:

\frac{24}{24 - 15} = \frac{x}{x - 25}

Solve for x

\frac{24}{9} = \frac{x}{x - 25}

Cross multiply

24(x - 25) = x(9)

24x - 600 = 9x

Subtract 24x from each side

- 600 = 9x - 24x

- 600 = -15x

Divide both sides by -15

40 = x

x = 40
