Answer:

3.4

Step-by-step explanation:

-12=-5(x-3)

destrubute

-5(x)--5(3)=-12

-5x + 15=-12

-15=-15

-5x=-17

x=-17/-5

x=3.4

Answer:

x = 27/5

Step-by-step explanation:

Step 1: Write equation

-12 = -5(x - 3)

Step 2: Solve for x

Distribute -5: -12 = -5x + 15
Subtract 15 on both sides: -27 = -5x
Divide both sides by -5: x = 27/5

Step 3: Check

Plug in x to verify it's a solution.

-12 = -5(27/5 - 3)

-12 = -5(12/5)

-12 = -12

What are the domain and ra range of the function (x) = 4x+52

SOVA2 [1]

Answer:

x = all real values

y = all real values

Step-by-step explanation:

The domain is the input values

f(x) = 4x+52 which is a line

The input or x values can be any value so the domain is all real values of x

The range is the output values

f(x) = 4x+52 which is a line

The output or y values can be any value so the domain is all real values of y

The sun shines at a 30° angle to the ground. To the nearest inch, how long is the shadow cast by a 72-in. tall fence post?

tensa zangetsu [6.8K]

The length of the shadow is 124.7 in

Explanation:

Given:

Angle, θ = 30°

Height of the fence, h = 72 in

Length of the shadow, l = ?

Given:

tan 30° = $\frac{perpendicular}{base} = \frac{height of the fence}{length of the shadow}$

$\frac{1}{\sqrt{3} } = \frac{72}{l} \\\\l = 72\sqrt{3} \\\\l = 124.7 in$

Therefore, the length of the shadow is 124.7 in

I need help please and fast

patriot [66]

Answer:

20%

Step-by-step explanation:

The reason it is 20% is due to the fact that if you put it in a form showing 250/250 = 100/100 and put another proportional rate underneath it showing 200/250 = x/100, you would have to multiply the numerator of the fraction on the left by the denominator of the fraction on the right to get 20000. Now you divide 250 from 20000 and get x for 80, resulting in 80/100 or 80%. All you have to do now is subtract 100-80, which equals 20, resulting in 20%.

Hope that helps!! It's my first time in answering so, ya. ;D goodluck!
