Find the scale factor then multiply 3 by scale factor to find m. Scale factor is found by dividing larger side by smaller side. In this example, divide 10 by 6. (10 / 6 = 1.66666...) This means the larger triangle is 1.6x bigger than the smaller one. Then multiply 3 by 1.6666.. to find m. Hope this helps! :)

Btw your answer would be m = 5 but I didn’t want to give that away right away.

A parabolic listening device is shaped such that the depth of the bowl depends on its radius and can be represented by the curve

goldfiish [28.3K]

The correct answer: 7.428 inches

Explanation:

Given the equation is D(r) = 0.145r^2

Where D is the depth and r is the radius
Putting D = 8 inches in the equation

8 = 55.2

r^2= 8/ 0.145

r^2 = 55.2

R^2= 7.428 inches

The radius of depth is 7.428 inche

Hope this help you : )

Does the system of equations have no solution, one solution, or an infinite number of solutions? −5x+y=−1−5x+y=10

kherson [118]

Answer:

5x-y=9, y=5x+19 write both equations in same formy=5x-9 for the first and havey=5x+19 for the second. These are two parallel lines with different intercepts. They do not intersect or coincide. No solutions

and y=6x+14, 12x-2y=-28 write both equations in same formy=6x+142y=12x+28 or y=6x+14. They are the same line. The solution is all of the points on the line.

Step-by-step explanation:

I hope it will help you have a great day bye and Mark brainlist if the answer is correct I am sorry if the answer is worng

Write the equation of a line in Slope Intercept Form that passes through (−2,3) and has a slope m=4.

Vladimir [108]

The slope is already given in the question so we can find the y-intercept.

Slope-intercept form: y = mx + b

3 = 4(-2) + b

3 = -8 + b

3 + 8 = -8 + b + 8

11 = b

Now, we can write the equation.

y = 4x + 11

Best of Luck!
