Answer:
yes he can
Step-by-step explanation:
he has to pay total is : 46+46x6%=48.76$
so he can pay that
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:
don´t know sorrry
Step-by-step explanation:
Answer:
D but dont get mad
Step-by-step explanation:
5x+8=-27
8 more means addition. -27 would be total. 5 times the number ( in this case x) would mean multiplication.
