Plug it into a graphing calculator, I used Desmos.
The graph is the same as x=-2 and y=-4. All I did was replace g(x) with y since y is the output function and so is g(x), then I just added the whole expression as follows and it graphed it for me.
The bottom graph to the left is the answer.
I hope this helps!

Answer: G = 50°, I = 50°, H = 80°
Step-by-step explanation:
First and foremos, the sum of three angles of a triangle is 180°
2x + 2x + (4x - 20) = 180°
8x - 20 = 180°
8x = 180° + 20 (adding 20 on both sides)
8x = 200°
x = 200/8
x = 25
The value of the angles can be found by replacing the value of x with 25
2x = 2 x 25 = 50°
Therefore, the angle of two angles are 50°
And the other is (4 x 25) -20 = 80°
Answer:
26
Step-by-step explanation:
When you flip two coins, you can have 4 different outcomes:
HH
HT
TH
TT
All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.
p(both heads) = 1/4
With 105 flips, the expected number of both heads is
105 * 1/4 = 26.25
Answer: 26
To make 5 dinner rolls, 1/2 cup of flour is used. How much is needed to make one dinner roll?
0.5 ÷ 5 = 0.1 ( for one dinner roll)
How many cups of flour are needed to make 3 dozen rolls?
3 × 12 = 36
0.1 × 36 = 3.6 (for 3 dozen rolls)
Answer:
y=11x-18
Step-by-step explanation:
y=11x+b (b is the unknown y-int)
to find the y-int, substitute in (2, 4), and solve for b *substitute in 2 for x and 4 for y*
y=11x+b
4=11(2)+b
4=22+b
b=-18
the equation of the line:
y=11x-18
