Step-by-step explanation:
<u>Given equation:</u>
a. write a second equation so that (1,3) is the only solution of the system
To have only one solution the equation must have a different slope.
<u>Let it be 10, then the y-intercept of y = 10x + b is:</u>
<u>And the equation:</u>
b. Write a second equation so that the system has infinitely many solutions
<u>To have infinitely many solutions, both equations must be same:</u>
c. Write a second equation so that the system has no solutions.
<u>To have no solutions, the equations must have same slope but different y-intercepts:</u>
Find the ratio of the known sides.
6/4 = 1.5
The larger triangle is 1.5 times larger than the smaller one.
Area is in square units, so to find the area of the larger triangle square the ratio and multiply that by the area of the known triangle.
1.5^2 x 40 = 90 square cm.
Answer:
I don't know
Step-by-step explanation:
Use the app and search it instead of waiting.

n=3
Answer:
y = 4/5x
Step-by-step explanation:
Two points on the graph is (-5, -4) and (0, 0)
Slope formula is [ y2-y1/x2-x1 ]
0-(-4)/0-(-5)
4/5
The y-intercept is non existent since its 0.
y = 4/5x
Best of Luck!
