Answer:

X cannot be solved for

Step-by-step explanation:

This isn't an equation because there's no equal sign and it cannot be simplified further. X values cannot be combined with non-x values.

Answer:

Part A: 12.5 cm

Part B: 0.8 km

Step-by-step explanation:

Map scale problems can be solved with proportions.

Part A

5 cm / 2 km = x cm / 5 km

5/2 = x/5

2x = 25

x = 12.5

Answer: 12.5 cm

Part B

5 cm / 2 km = 2 cm / x km

5/2 = 2/x

5x = 4

x = 4/5

x = 0.8

Answer: 0.8 km

Write an equation of the line (-8, -5) (-3, 10)

bezimeni [28]

Answer:

y = 3x + 19

Step-by-step explanation:

1) Compute the slope (Slope = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$ )

m = $\frac{10 - (-5)}{-3-(-8)}$

2) Refine

m = 3

3) Plug the slope (3) into y = mx + b

y = 3x + b

4) Plug in (-8,-5), x = -8, y = -5

-5 = 3(-8) + b

5) Isolate b

b = 19

6) Construct the line equation y = mx + b

y = 3x + 19
