Answer:
Top Row:20,20
Bottom Row:26,26
Step-by-step explanation:
2(3m+7) when m is 1. Plug in to get: 2 (3*(1) + 7)=20
6m+14 when m is 1. Plug in to get: 6*(1) + 14=20
2(3m+7) when m is 2. Plug in to get: 2 (3*(2) + 7)=26
6m+14 when m is 2. Plug in to get: 6*(2) + 14=26
Answer:
x/y
13/0
13/1
Step-by-step explanation: I hope it's right :)
Answer:
y = -5/4x - 3/2
Step-by-step explanation:
y2 - y1 / x2 - x1
6 - (-4) / -6 - 2
10 / -8
= -5/4
-4 = -5/4(2) + b
-4 = -5/2 + b
-3/2
For this case, we propose a rule of three, since with \ frac {2} {3} of gallons it covers 3% of wall, then:
gallon --------> 3%
1 gallon -----------------------> x
Where the variable "x" represents what percentage of wall can be painted with 1 gallon of paint. So:
Thus, with 1 gallon of paint 4.5% of wall are painted.
Answer:
4.5%
An independent variable is something that is changed or controlled
