Answer:

x=8, AS=8

Step-by-step explanation:

You know that triangles ASR and ABC are similar, because they share angle A and they both have a right angle. Therefore, the ratio of their side lengths should also be constant.

10:5=x:4

x=8

Hope this helps!

ΔACD and ΔASR are the same so we can write a ratio:

x/4 = 10/5

x/4 = 2

x/4 * 4 = 2 * 4

x = 8

Since AS is equal to x, they are both the same.

Therefore, the answer is [ x = 8, AS = 8 ]

Best of Luck!

The graph of linear function k passes through the points (-3, 0) and (1, 8). Which statement must be true?

grin007 [14]

Answer:

B. The slope of the graph of k is 2.

Step-by-step explanation:

<h3>Find the equation of the line.</h3>

The slope is:

m = (8 - 0)/(1 + 3) = 2

The y-intercept is:

0 = -3*2 + b
b = 6

The line is:

y = 2x + 6

<h3>Now lets look at the answer options</h3>

A. The x-Intercept of the graph of k is 8.

The x- intercept is -3, False

B. The slope of the graph of k is 2.

m = 2, True

C. The graph of k passes through (-1, -8).

-8 = 2(-1) + 6
-8 = 4, False

D. The zero of k is 3.

x = 0 ⇒ y = 0+ 6 = 6, False

Si f(x) = 1/2x^2-(1/4x+3),¿cuál es el valor de f(8)? (3) 27 (2) 17 (4) 33 (1) 11

gavmur [86]

Answer:

Step-by-step explanation:

To evaluate f(8) substitute x = 8 into f(x)

f(8) = $\frac{1}{2}$ × 8² - ( $\frac{1}{4}$ × 8 + 3)

= $\frac{1}{2}$ × 64 - (2 + 3)

= 32 - 5

= 27
