What is x in the similar triangles? Please help:)

topjm [15]

Answer:

x = 18

Step-by-step explanation:

Since both right triangles are similar, therefore:

$\frac{2x - 6}{20} = \frac{39}{x + 8}$

Cross multiply

$(2x - 6)(x + 8) = 39*20$

$2x(x + 8) -6(x + 8) = 780$

$2x^2 + 16x - 6x - 48 = 780$

$2x^2 + 10x - 48 = 780$

Subtract 780 from both sides

$2x^2 + 10x - 48 - 780 = 0$

$2x^2 + 10x - 828 = 0$

$2x^2 + 46x - 36x - 828 = 0$

$2x(x + 23) - 36(x + 23) = 0$

$(x + 23)(2x - 36) = 0$

x + 23 = 0

x = -23

2x - 36 = 0

2x = 36

x = 18

If the point x,y is on the y-axis which of the following is true x=0 y=0

xz_007 [3.2K]

Hi there!

Answer:

x=0

<u><em>How it works:</em></u>

In coordinate planes, x always goes first. Then the y comes next. If x is 0, and y is also zero, none of those would be in the y axis place...

If the x is in 0 and the y is 1,2,3,4,5.... then the y axis would be in the y axis and x would just stay the same...

If the x is 1, then the y would be 0 which means that there would be nothing in the y axis.

Therefore, the answer is x=0..

please help me find the slope of the line graphed below ! (will mark brainliest) and spammers will be reported.

Aloiza [94]

Answer:

slope = $\frac{5}{4}$

Step-by-step explanation:

Given the two points on the graph: (-1, 2) (-5, -3)

Let (x1, y1) = (-1, 2)

(x2, y2) = (-5, -3)

We can use the following slope formula:

$m = \frac{y2 - y1}{x2 - x1}$

Substitute the values into the slope formula:

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

Therefore, the slope of the line is: $\frac{5}{4}$
