Answer:
One rule for dividing fractions is the rule where instead of doing 13/43, you can do 13 times 1/43.
Step-by-step explanation:
Yeah
In linear models there is a constant additve rate of change. For example, in the equation y = mx + b, m is the constanta additivie rate of change.
In exponential models there is a constant multiplicative rate of change.
The function of the graph seems of the exponential type, so we can expect a constant multiplicative exponential rate.
We can test that using several pair of points.
The multiplicative rate of change is calcualted in this way:
[f(a) / f(b) ] / (a - b)
Use the points given in the graph: (2, 12.5) , (1, 5) , (0, 2) , (-1, 0.8)
[12.5 / 5] / (2 - 1) = 2.5
[5 / 2] / (1 - 0) = 2.5
[2 / 0.8] / (0 - (-1) ) = 2.5
Then, do doubt, the answer is 2.5
Answer:
Step-by-step explanation:
1) If 
is needed to cover 
than we need 3 more: ![\frac{5}{6}(3)=\frac{15}{6} =2\frac{3}{6} gallons2) But we still need to add the beginning [tex]\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D%283%29%3D%5Cfrac%7B15%7D%7B6%7D%20%3D2%5Cfrac%7B3%7D%7B6%7D%20gallons%3C%2Fp%3E%3Cp%3E2%29%20But%20we%20still%20need%20to%20add%20the%20beginning%20%5Btex%5D%5Cfrac%7B5%7D%7B6%7D)

Answer:
x= -5
y= -2
Step-by-step explanation:
From the equation y=x+3-------eqn 1
x+y= -7-------eqn2
x+(x+3)= -7 (since there is no value before the bracket is 1, so multiply by 1)
x+x+3= -7
2x+3=-7
2x=-7-3
2x=-10
x=-10/2
x=-5
Insert x value in equation 1
y= -5+3
y=-2
