Answer:

Step-by-step explanation:

Multiply each side by -5.

Switch signs when multiplying or dividing by a negative integer.

Answer:
9 is the number
Step-by-step explanation:
Let's call this number x
The equation is:
30+2x=48
subtract 30 from both sides and you get
2x=18
divide 2 from both sides and you get
x=9
Therefore, 30+2(9)=48
I think it talks about if this is a one to one function or not
Answer:
The greater unit rate of the two functions is the first function shown by the table and the greater y intercept is the second function shown by the graph.
Step-by-step explanation:
Find the slope of both equations
(15-5)/(5-0) = 2
(6-0)/(0+4) = 3/2
2>3/2
y-intercept is where the function crosses the y axis, function 1 y-intercept is 5 and the y-intercept of function 2 is 6, 6>5
Convert the fractions so they both have the same denominator (bottom part of the fraction)
1/5 = 7/35
This is because 5*7=35, so 1*7=7
1/7 = 5/35
This is because 7*5=35, so 1*5 =5
Then subtract the top numbers to get the answer:
