Please help me with 8, 9, and 10 thanks! Show work too

Harrizon [31]

In 8, 9, 10, all the triangles are similar, meaning corresponding sides have the same ratio.

8. hypotenuse / (short side) = 25/x = x/9
x² = 25*9 = 5²×3²
x = √(5²×3²) = 5*3 = 15

9. (long side) / (short side) = x/7 = 9/x
x² = 7*9
x = √(9*7) = 3√7

10. (short side) / (long side) = x/48 = 48/64
x = 48²/64 = 36

Answer:

The value of f(x) when x=-1 is 0.5

Therefore $f(-1)=0.5$

Step-by-step explanation:

Given that y=f(x)= $2^x$

to find the f(x) when x=-1 :

That is to find f(-1)

Put x=-1 in the given function f(x)= $2^x$

$f(-1)=2^{-1}$

$=\frac{1}{2}$

$=0.5$

Therefore $f(-1)=0.5$

The value of f(x) when x=-1 is 0.5

Write an equation of the line in slope-intercept form: y-intercept of 2, x-intercept of 4

zvonat [6]

Answer:

$\sf y=-\dfrac12x+2$

Step-by-step explanation:

y-intercept is when x = 0, so (0, 2)

x-intercept is when y = 0, so (4, 0)

$\sf slope=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{0-2}{4-0}=-\dfrac12$

Slope-intercept form of linear equation: $\sf y=mx+b$

(where m is the slope and b is the y-intercept)

Given:

$\sf m=-\dfrac12$
b = 2

$\sf \implies y=-\dfrac12x+2$
