Answer:

Step-by-step explanation:

(0,2) ; (3 , -2)

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\$

$= \frac{-2-2}{3-0}\\\\= \frac{-4}{3}\\\\$

m = (-4)/3 ; (0 , 2)

y -y1 =m(x -x1)

$y - 2 = \frac{-4}{3}(x-0)\\\\y -2 = \frac{-4}{3}*x\\\\ y = \frac{-4}{3}x + 2$

Your boss gave you a raise. Your weekly salary went from $375 to $450. What was your percent raise?

Yuri [45]

1. Find the difference
2. Divide the difference by the original number it went up from.

450-375 = 75

75/375 = 0.2

You got a 20% raise.

Proof:
375*.2 = 75
375+75 = 450

A viewfinder has a triangular lens. Some of the measurement of the length are shown below. Which of the following best represent

S_A_V [24]

Answer:

Step-by-step explanation:

First, we need to find the unknown angle of the triangle.

40 + 20 = 60

180 - 60 = 120

So the unknown angle is 120.

Then, we can use the law of sines to create a proportion.

sin(120)/8 = sin(40)/a

Then, we can simplify this.

a is about 5.9, or answer choice A.

Someone please help.

Hi there!

$f(x)+f(x+1)=4f(x)$

There are 3 parts to this equation:

f(x)

f(x+1)

4f(x)

We must first determine these three parts separately.

1) f(x)

We're given that $f(x)=3^x$ :

⇒ $f(x)=3^x$ :

2) f(x+1)

Now, we must find f(x+1). To do so, add 1 to x in the original function $f(x)=3^x$ :

⇒ $f(x+1)=3^x^+^1$

3) 4f(x)

To find 4f(x), multiply the original function $f(x)=3^x$ by 4:

$4f(x)=4*3^x$ :

4) Put it all together

Now, plug each of the three parts into the equation $f(x)+f(x+1)=4f(x)$ :

$f(x)+f(x+1)=4f(x)$

$3^x+3^x^+^1=4*3^x\\3^x+3^x*3=4*3^x$

Factor the left side

$3^x*(1+3)=4*3^x$

Divide both sides by 3^x

$1+3=4\\4=4$

Because this equation is true, $f(x)+f(x+1)=4f(x)$ is therefore true.

I hope this helps!
