Part B is saying to equal the both equations, so
5x + 2 = 5x + 5
Take a look, we have the same multiplicative to our variable, but we have different sums, so, if we just say x = 0 we wil have:
5.0 + 2 = 5.0 + 5
0 + 2 = 0 + 5
2 = 5
And of course it's not true, 2 will never be equal to 5, so we can say there's no solution for x.
Another way to see this is:
5x + 2 = 5x + 5
5x - 5x = 5 - 2
0 = 3
0 of couse isn't equal to 3.
C, -$154 < -$107 because -107 is closer to 0 than -154
Answer:
24 feet tall
Step-by-step explanation:
First you divide 6 by 10 and then you get 0.6, you then multiply 0.6 by 40 and you get 24.
Answer:
Step-by-step explanation:
536 because it is correct
Answer:
Part a) The graph in the attached figure
Part b) The units rate of change is 9
Step-by-step explanation:
we know that
A relationship between two variables, t, and d, represent a proportional variation if it can be expressed in the form
or 
step 1
Find the constant of proportionality k
For 
substitute


the linear equation is equal to

using a graphing tool
see the attached figure
step 2
Find the unit rate
we know that
In a proportional relationship the constant of proportionality k is equal to the unit rate of change or slope m of the line, because the line passes through the origin
so
The units rate of change is 9
That means------> A change of 1 unit in t correspond to a change of 9 units in d
see the attached figure to better understand the problem
