Answer:

e. 10√30

Step-by-step explanation:

In this right triangle geometry, all of the right triangles are similar. This means that the ratio of long side to hypotenuse is the same for all triangles:

x/(10+50) = 50/x

Multiplying by 60x, we have ...

x^2 = 3000

x = 10√30 . . . . . take the square root. Matches choice E.

<em>Comment on estimating</em>

You're looking for x. Examining the figure, you see that x is the long side of the triangle with hypotenuse 10+50=60, so it will be shorter than that value. x is also the hypotenuse of the triangle with long side 50. So, x will be longer than 50.

The only answer choice with a value between 50 and 60 is choice E.

You don't even need to know how to find x. You only need to know that the hypotenuse is the longest side in a right triangle.

AV = AX

2x + 1 = x + 3

x + 1 = 3

x = 2

BV = (2/3)ZV

3x + 2 = (2/3)ZV

3(2) + 2 = (2/3)ZV

6 + 2 = (2/3)ZV

8 = (2/3)ZV

24 = 2ZV

ZV = 12

1. 9c-3c=48A) c=9B) c=3C) c=4D) C=8

Alona [7]

$9c\text{ - 3c = 48}$

To solve this equation, we need to subtract both, 9c - 3c:

$9c\text{ - 3c = 6c = 48}$

Dividing by 6 at both sides of the equation

$\frac{6c}{c}\text{ = }\frac{48}{6}$

Then

$c\text{ = 8}$

Then the answer C = 8. (Option D)

If g(x)=3x-2, find g(8)-g(-5)

Brut [27]

<h2>Answer:</h2> $g(8)-g(-5)=39$

<h2>Explanations:</h2>

Given the function

$g(x)=3x-2$

Get g(8) by substituting x = 8 into the function;

$\begin{gathered} g(8)=3(8)-2 \\ g(8)=24-2 \\ g(8)=22 \end{gathered}$

Get g(-5) by substituting x = -5 into the function

$\begin{gathered} g(-5)=3(-5)-2 \\ g(-5)=-15-2 \\ g(-5)=-17 \end{gathered}$

Take the difference in the result to have;

$\begin{gathered} g(8)-g(-5) \\ =22-\mleft(-17\mright) \\ =22+17 \\ =39 \end{gathered}$

Hence the difference between the given functions is 39

Write the expression for when you translate the graph of y = |3x|− 5 one unit to the right.

DedPeter [7]

Answer:

$y=|3x-3|-5$

Step-by-step explanation:

Notice that we are requested to perform a horizontal shift of on unit to the right. Recall that a horizontal shift of one unit to the right involves the operation of subtracting from the variable "x" one unit.

Therefore, this implies the following mathematical transformation to the variable "x":

$y=|3(x-1)|-5\\y=|3x-3|-5$

where we simply completed distributive property to get rid of the parenthesis inside the absolute value.
