Answer:


Step-by-step explanation:

0.01x−0.3y=1;y=0.1x−2

Rewrite equations:

y=0.1x−2;0.01x−0.3y=1

Step: Solvey=0.1x−2for y:

y=0.1x−2

Step: Substitute0.1x−2foryin0.01x−0.3y=1:

0.01x−0.3y=1

0.01x−0.3(0.1x−2)=1

−0.02x+0.6=1(Simplify both sides of the equation)

−0.02x+0.6+−0.6=1+−0.6(Add -0.6 to both sides)

−0.02x=0.4

−0.02x

−0.02

=

0.4

−0.02

(Divide both sides by -0.02)

x=−20

Step: Substitute−20forxiny=0.1x−2:

y=0.1x−2

y=(0.1)(−20)−2

y=−4(Simplify both sides of the equation)

Answer:

x=−20 and y=−4

Simple...

you have: 

1.) Find the slope of the line using (-2,1) and (3,6)

Using \frac{ y_{1}-  y_{2} }{ x_{1} - x_{2}  }

\frac{1-6}{-2-3} = \frac{-5}{-5}

m=1 (slope)

2.)Tell whether the equation, 8y+3=5x+3, is a direct variation.

y=\frac{5x}{8} (None)

3.)What is the slope and y-intercept of the graph of the equation y=2x+3?

Slope =2 

y-intercept=3

C.

Thus, your answer.
