Mathematics

natta225 [31]3 years ago
4 0

Answer:

-4=x

Step-by-step explanation:

f(x) = -3x + 6

Let f(x) = 18

18 = -3x+6

Subtract 6 from each side

18-6 = -3x+6-6

12 = -3x

Divide each side by -3

12/-3 = -3x/-3

-4=x

In which order should you look for assistance with college expenses?
lyudmila [28]
The correct answer should be Choice B. 

Scholarships and merit aid are the best way to earn money to go to college. They don't have to be paid back. When it comes to loans, you should select federal before non-governmental because the interest rates are usually lower on federal loans.

Prove using the Pythagorean theorem that AC is perpendicular to AB given points ????(−2, −2), ????(5, −2), and
Tems11 [23]

Answer:

(BC)^2=(AC)^2+(AB)^2. It means AC is perpendicular to AB.

Step-by-step explanation:

Vertices of given triangle are A(−2, −2), B(5, −2), and C(−2,22).

Distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using distance formula we get

AB=\sqrt{(5-(-2))^2+(-2-(-2))^2}=\sqrt{7^2}=7

BC=\sqrt{(-2-5)^2+(22-(-2))^2}=\sqrt{7^2+24^2}=\sqrt{625}=25

AC=\sqrt{(-2-(-2))^2+(22-(-2))^2}=\sqrt{24^2}=24

According to Pythagoras theorem

hypotenuse^2=perpendicular^2+base^2

(BC)^2=(AC)^2+(AB)^2

Perpendicular = AC

Base = AB

It means AC is perpendicular to AB.

Hence proved.
