What is the y-intercept?​

Mathematics
1 answer:
Reika [66]3 years ago
7 0

Answer:

(0, 9)

Step-by-step explanation:

The y-intercept is the point when x = 0. By looking at the graph, when x = 0, y = 9. Therefore, the y-intercept of the line is (0, 9).

Solve the following:<br> 2(x+3)=x-4
Anon25 [30]

Answer:

x = -10

Step-by-step explanation:

2(x + 3) = x + -4

Reorder the terms:

2(3 + x) = x + -4

(3 * 2 + x * 2) = x + -4

(6 + 2x) = x + -4

Reorder the terms:

6 + 2x = -4 + x

Solving

6 + 2x = -4 + x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.

6 + 2x + -1x = -4 + x + -1x

Combine like terms: 2x + -1x = 1x

6 + 1x = -4 + x + -1x

Combine like terms: x + -1x = 0

6 + 1x = -4 + 0

6 + 1x = -4

Add '-6' to each side of the equation.

6 + -6 + 1x = -4 + -6

Combine like terms: 6 + -6 = 0

0 + 1x = -4 + -6

1x = -4 + -6

Combine like terms: -4 + -6 = -10

1x = -10

Divide each side by '1'.

x = -10

Please help! Final problem for tonight
DedPeter [7]

(4x-6)+(8x+18)=180(adjacent angles are supplementary)

4x-6+8x+18=180

4x+8x-6+18=180

12x+12=180

12x=180-12

12x=168

x168/12

x=14

8x+18=y+3 (corresponding angles are equal)

8×14+18=y+3

130=y+3

-y=3-130

-y=-127

y=127

x=14, y=127
