Answer:

Step-by-step explanation:

1. To find x make these 2 equations equivalent to each othe.

$3x + 6 = 8x - 10$

2. Subtract x terms from both sides

$(3x - 8x) + 6 = (8x - 8x) - 10$

3. Subtract constant from left side.

$-5x + 6 = -10$

$-5x + (6 - 6) = (-10 - 6)$

$-5x = -16$

4. Divide be x term from the left side.

Find the distance between the pair of points and then round your answer to the nearest tenth.

Travka [436]

Answer:

$d = 9.4 units$ (nearest tenth)

Step-by-step explanation:

Given the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , distance between (-4, 5) and (4, 0) is calculated as follows:

Let $(-4, 5) = (x_1, y_1)$

$(4, 0) = (x_2, y_2)$

$d = \sqrt{(4 - (-4))^2 + (0 - 5)^2}$

$d = \sqrt{(8)^2 + (- 5)^2}$

$d = \sqrt{64 + 25}$

$d = \sqrt{89}$

$d = 9.4 units$ (nearest tenth)

What it the x and y intercept of y=2x^2+3x+1

babunello [35]

x = -1

y = 1

To find this, input the equation into a graphing calculator, whether online or an actual one, and you have two options:

1 - Search for the points in which the line crosses the x and or y axis.

2 - Hit 2nd Graph to access the table and find when x and y equal zero.

Hope this helps!
