Identify the SLOPE (m) and the Y-INTERCEPT (b).

To find the y-intercept, find the point where the line crosses the y-axis.

To find the slope, pick two points on the line that are easy to read.
Then see how many units up or down and how many units right or left you need to go from the first point to the second point. Divide the up or down (the rise) by the right or left (the run). That is the slope.

The equation is

y = mx + b,

where m = slope and b = y-intercept.

Solve the absolute value equation<br> algebraically: 3|2x - 3| + 2 = 3

kupik [55]

Answer:

$3 |2x - 3| = 1$

$3 |2x - 3| = 1 \\ 6x - 9 = 1 \\ 6x = 10 \\ x = \frac{10}{6} = \frac{5}{3}$

$3 |2x - 3| = - 1 \\ 6x - 9 = - 1 \\ 6x = 8 \\ x = \frac{4}{3}$

$x = \frac{5}{3} x = \frac{4}{3}$

I am sorry but I am not sure of this :(

A right triangle is drawn on a coordinate plane. Two vertices of the triangle are points R(−9,6) and T(10,−7) . The third vertex

SSSSS [86.1K]

The coordinates of point S would be (10,6), so the distance from point T to point S would be 13. :)

16,000 rolls of paper were purchased and 12,500 were sold at $1.79, what is the total ending inventory?

Maslowich

12,500 x 1.79 to find the price but 16,000 - 12,500 to get how many were left.
12,500 x 1.79 = $22,375 that they made from selling. 16,000 - 12,500 = 3,500 rolls left in the inventory. This question confused me so I just gave both answers.
