Plot a point on the coordinate plane to represent each of the ratio values in the table. Time (h) Distance (km) able displaying

Effectus [21]

Answer:

Refer the attached graph.

Step-by-step explanation:

Given : Time (h) Distance (km) able displaying Time in hours in one column and Distance in kilometers in the other. The time column contains 1, 3, 6, and 9. The distance column contains 2, 6, 12, and 18.

To plot : The points on the coordinate plane.

Solution :

Time is independent variable so it is taken on x-axis.

Distance is taken on y-axis.

x y

1 2

3 6

6 12

9 18

When we plot these points in the coordinate plane, we get a linear equation.

The linear equation form is $y=2x$

Select the ordered pair that is the solution of this equation: -7x – 4y = 6

Olegator [25]

Its just a matter of subbing

-7x - 4y = 6....subbing in (-2,2)...x = -2 and y = 2
-7(-2) - 4(2) = 6
14 - 8 = 6
6 = 6 (correct)

so ur solution is (-2,2)

Maria invests $600 in a bank account that earns simple interest. She earns $30 at the end of 12 months. Janae invests $350 at th

olga nikolaevna [1]

I believe the answer is $17.50, she earned $30 off of $600 meaning she had a 5% interest rate and 5% of 350 is $17.50
