How can you solve
an equation or inequality by graphing?

Answers

Answer 1
Example: y ≤ x + 2

There are three steps:

Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).

The number of chirps per minute is 72

Step-by-step explanation:

Here, using the formula given, we want to find the number N representing the number of chirps per minute.

To get this, we shall simply substitute the value of 58 for T in the equation;

Thus;

58 = 50 + (N-40)/4

58 -50 = (N-40)/4

8 = (N-40)/4

4 * 8 = N -40

32 = N -40

N = 40 + 32

N = 72

The wind blew away 33 of your muffins. That was 3/4 of all of them! With how many did you start

Answers

Answer:

44

because each that's ¼ has 11 so 11x4 =44

You can translate this into the statement “33 is 3/4 of what number?”
Translating that into math, you have:
     33 is 3/4 of what number?
     33 =  3/4 •   x

To solve 33 = 3/4•x, you divide both sides by 3/4

33÷ (3/4) = x

To divide by a fraction means you multiply by it’s reciprocal, 4/3.

33 ÷ (3/4) = 33 • 4/3

33 • 4/3 = 44

You started with 44 muffins.
