Answer:

x=30, and angle A equals 132°.

Step-by-step explanation:

Since the angles are alternate-interior, both angles A and B equal the same amount. To figure out the value of x, you'd need to set up your equation like this:

5x-18°=3x+42°

You would need to solve for x, which should equal to 30.

Once you get your x, you need to plug it in into the equation of angle A, which is 5x-18°:

5(30)-18°

150-18°

Angle A = 132°.

PLEASE HELP ALGEBRA 2 Question is on the photo below

Sedbober [7]

Answer:

The value of f(x) - g(x) is:

f(x) - g(x) = 2x² + 6x - 4

Step-by-step explanation:

Given

f(x) = 3x² + x - 3

g(x) = x² - 5x + 1

To determine

f(x) - g(x)

Using the formula

f(x) - g(x) = 3x² + x - 3 - ( x² - 5x + 1)

= 3x² + x - 3 - x² + 5x - 1

= 2x² + 6x - 4

Therefore, the value of f(x) - g(x) is:

f(x) - g(x) = 2x² + 6x - 4

Choose the linear inequality that describes the graph. The gray area represents the shaded region.

jek_recluse [69]

Answer:

2x + 3y ≥ 5

Step-by-step explanation:

See the graph attached.

The bold straight line passes through the points (1,1) and (4,-1).

Therefore, the equation of the straight line will be

$\frac{y + 1}{- 1 - 1} = \frac{x - 4}{4 - 1}$

⇒ 3(y + 1) = - 2(x - 4)

⇒ 3y + 3 = - 2x + 8

⇒ 2x + 3y = 5 ............. (1)

Now, the shaded region i.e. the solution to the inequality does not include the origin(0,0).

So, putting x = 0 and y = 0 in the equation (1) we get, 0 < 5

Therefore, the inequality equation is 2x + 3y ≥ 5 (Answer)
