Heeelp . Can someone please answer this to meee ? .

Answer:

If f(x)=g(x), the solution is x=-2

Step-by-step explanation:

We are given:

$f(x)=3x+3\\g(x)= (-1/2)x-4$

We need to find the solution if f(x)=g(x)

Now solving for f(x)=g(x)

$f(x)=g(x)\\3x+3=(-\frac{1}{2}x)-4\\3x+3=-\frac{1}{2}x-4\\3x+\frac{1}{2}x=-4-3\\\frac{3x*2+x}{2}=-7\\\frac{6x+x}{2}=-7\\\frac{7x}{2}=-7\\x=-7*\frac{2}{7}\\x=-2$

If f(x)=g(x), the solution is x=-2

A right triangle has side lengths a, b, and c as shown below.

Musya8 [376]

Answer:

$\bold{\sin x = \frac{b}{c}}\bold{\\\cos x = \frac{a}{c}}\bold{\\\tan x = \frac{b}{a}}$

Step-by-step explanation:

Given that

A right triangle has side lengths a, b, and c

Because you did not attached photo of the right triangle so I will assume that:

Side a is the adjacent (A)
Side b is the opposite (O)
Side c is the hypotenuse (H)

(Please have a look at the attached photo)

To solve for the trigonometric functions of x, we need to recall the ratios they represent as shown below.

$\sin x = \frac{O}{H}\\\cos x = \frac{A}{H}\\\tan x = \frac{O}{A}$

EX: the sine of x is equal to the side opposite of angle x over the hypotenuse. Hence, we have the expressions of the trigonometric functions as shown below:

$\bold{\sin x = \frac{b}{c}}\bold{\\\cos x = \frac{a}{c}}\bold{\\\tan x = \frac{b}{a}}$

Hope it will find you well

Factor.

yawa3891 [41]

Answer:

A) (2x + 1)(x + 3)

Step-by-step explanation:

Factor 2x² + 7x + 3

Since 2 is prime (it's only factors are 1 and itself) we know we can start out our factors as..

(2x + a)(x + b)

Three is also prime, so we either have

(2x + 1)(x + 3)

(2x + 3)(x + 1)

Foiling (2x + 1)(x + 3) will give us the result we want. So the answer is A

Bryan sells cars. He makes a salary of $500 a week, plus $150 for every car he sells. This week, he wants to make at least $2000

Kobotan [32]

If Bryan wants to make $2000 dollars then he needs to solve this equation:

2000=500+150x
-500 -500

1500=150x divide by 150 on both sides

x=10

10 cars
