Answer:
2)16.5
Step-by-step explanation:
step1:v/2.2 -0.1=7.4
add 0.1 on both sides
step2:v/2.2=7.5
multiply by 2.2 on both sides
step3:v=16.5

Answer: y = 3x+4</h3>
Slope = 3
y intercept = 4
========================================================
Explanation:
Let's find the slope.
The slope is m = 3.
The y intercept is b = 4 due to the point (0,4). The y intercept <u>always</u> occurs when x = 0.
We'll then plug those m and b values into y = mx+b to get the answer y = 3x+4
-----------
As a way to check the answer, plugging x = 0 should lead to y = 4
y = 3x+4
y = 3*0+4
y = 0+4
y = 4
So that works out. Let's try x = 1. It should produce y = 7
y = 3x+4
y = 3*1+4
y = 3+4
y = 7
That works out also. The answer is fully confirmed.
Answer:
Knowing that the object is a rectangle, and that the base is 2x the height, you could say that h=height and b=base (and the base is the same as width since the object is a rectangle) then a possible equation you could construct is 2(h+2b)
Step-by-step explanation:
For example, using this equation with numbers may look like the following:
- 2(h+2b)
- 2(21+2*21)
- 2(21+42)
- 2(61)
- =122
Hopefully I was able to help you :) I would love to hear some feedback if possible and if you were able to find a simpler way.
7. The ratio is 2 to 1, so the equation would be 2r=c. r is the number of recipes and c is the number of cups.
