<h3>Answer:</h3>

x=2

<h3>Step-by-step explanation:</h3>

Using similarity and enlargement;

ΔABE is similar to ΔACD

Therefore, the ratios of corresponding sides will be equal.
That is; AC/AB = AD/AE = CD/BE

In this case;

AC = 48

AB = 36

AE = 24

AD = 24 + 6x - 4

= 20 + 6x

Therefore;

$\frac{48}{36}=\frac{20+6x}{24}$

Thus;

(48 × 24) = 36(20 + 6x)

1152 = 720 + 216x

216x = 1152 - 720

216x = 432

x = 432 ÷ 216

= 2

Therefore, the value of x is 2

flooring a value, simply means, dropping it to the closest integer, so for the floor function or ⌊x⌋, that means

⌊ 2.5 ⌋ = 2

⌊ 2.00000001 ⌋ = 2

⌊ 2.999999999999⌋ = 2

⌊ -2.0000000001⌋ = -3

⌊ -2.999999999999⌋ = -3

let's recall that on the negative side of the number line, the farther from 0, the smaller, so -1,000,000 is a tiny number compared to the much larger -1.

⌊ -5.2 ⌋ = -6.

Eric was rock climbing. At one point, he stopped and climbed straight down 2\dfrac{1}{2}2

nikitadnepr [17]

The equation that matches the given situation is $-2\frac{1}{2}+6\frac{3}{4}=?$ . So, after two moves, Eric's elevation changed $4\frac{1}{4}$ meters above.

We know that in mathematics, subtraction means removing something from a group or a number of things. What is left in the group gets smaller when we subtract. The minuend is the first element we use. The subtrahend is the part that is being removed. The difference is the portion that remains after subtraction.

Assume that "negative" means climbing down and "positive" means climbing up. We must locate the elevation change in this area.

Given that Eric climbed straight down $2\frac{1}{2}$ meters. So we can write $-2\frac{1}{2}$ .

Again Eric climbed straight up $6\frac{3}{4}$ meters. So, we can write $6\frac{3}{4}$ .

Then the change = $-2\frac{1}{2}+6\frac{3}{4}$

= $-\frac{(2*2+1)}{2}+\frac{6*4+3}{4}$

= $-\frac{5}{2} +\frac{27}{4}$

= $\frac{-(5*2)+27}{4}$

= $\frac{-10+27}{4}$

= $\frac{17}{4}$

= $\frac{4*4+1}{4}$

= $4\frac{1}{4}$

Therefore, the equation that matches the given situation is $-2\frac{1}{2}+6\frac{3}{4}=?$ . So, after two moves, Eric's elevation changed $4\frac{1}{4}$ meters above.

Question

IRINA_888 [86]

Answer:

$m=\frac{5}{3}$

Step-by-step explanation:

Given the following question:

Point A = (-2, -9) = (x1, y1)
Point B = (1, -4) = (x2, y2)

To find the slope of a line, we will need to use the formula for slope or rise over run.

$m=\frac{y2-y1}{x2-x1}$
$m=\frac{-4--9}{1--2} =\frac{5}{3}$
$m=\frac{5}{3}$

The slope of the given line is indeed "5/3."

Hope this helps.
