Answer:

look at explanation for answer...

Step-by-step explanation:

y = 2x + 1

so you want the coordinates (1,3)

so you input the x coordinate into the equation,

y = 2(1) + 1

y = 2 + 1

y = 3

but if you have to write a new equation to get coordinates (1,3)

you could write the equation

y = 3x

The comeplement of 99
harkovskaia [24]
1. the complement is when two angles add up to 99 degrees and the supplement is when the two angles add up to 180 degrees.

2. Let x be the measure of the unknown angle .

3. Let 90 -x be it's complement and 180- x be the supplement of the angle .

4. Given 90-x=3x+9 the measure of the complement of an angle is 3x+9. Solve using the following steps.

99-x=3x+9
Add x-9 to both sides to isolate x-terms on right side and numbers on left
90-x+x-9=3x+9+x-9

90-x+x-9=3x+9+x-9

91=4x
divide by 4 to both sides yields
91/4=x

5. Given 3x+99=180-x. The measure of the supplement of an angle is 3x+99. So
3x+99=180-x

Add x+99 to both sides of equations to isolate x on right side and number on left
3x+99+x-99=180-x+x-99

4x=91

X=91/4

6. The angle is x=91/4

Y raise to power 1/2 =3​
marta [7]

Answer:

y = root 9

Step-by-step explanation:

1/2 is equivalent to the root of something.

The root of y equals 3.

Therefore, y would be equal to root 9, as root 9 is equivalent to 3.

Hope this helps :)

Find the measure of
Alborosie
Angle B is HALF of the sum of the two angles it intercepts.

Since it intercepts 48 and 142 degrees, simply add them add divide by 2:
B = (48 + 142)/2
B = 190/2
B = 95

The measure of angle B is 95 degrees.
