Answer:
-7.5x -12.5, x < -17.5x +2.5, x ≥ -1Step-by-step explanation:
The absolute value function changes slope at its vertex. Here, that vertex is translated to x = -1. To the left of that point, the function is equivalent to one that negates its argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
for (x+1) < 0
y = -7.5(x +1) -5 = -7.5x -12.5
for (x+1) ≥ 0
y = 7.5(x +1) -5 = 7.5x +2.5
This means we can write the piecewise function as ...
[tex]y=\begin{cases}-7.5x-12.5,&\text{if }x<-1\\7.5x+2.5,&\text{if }x\ge-1\end{cases}[/tex]

Determine whether the ratios form a proportion.
16/9, 28/15
Answer:
No
Step-by-step explanation:
One way of doing this problem is to reduce the given fractions as much as possible. Unfortunately, neither ratio reduces. So the fraction 16/9 is NOT equal to the fraction 28/15 and our conclusion must therefore be "the rations do not form a proportion."
Answer:
hope it helps 12 : 9 = 28 : 15
is FALSE

Juan has 20 books to sell. He sells the books for $15 each.
The amount of money Juan makes from selling x books is represented by the equation y=15x
y
=
15
x
What is the theoretical range of the equation?
Question 2 options:
All multiples of 20 between 0 and 300, inclusive
All integers from 0 to 20, inclusive
All multiples of 15 between 0 and 300, inclusive
All real numbers
Answer:
Well u would multiply 20 x 15 to find out the highest if the range which is 300 . So that knocks it down to B or D. But since they're $15 each, It would be based of the multiples of 15 making your answer B .
The range is all the y values.....or the f(x) values .
So the practical range would be the multiples of 15 between 0 and 300,Inclusive .
Hope this helps you!!Mae buys 7 boxes of drinks. The cost of each box of drinks is £7 and each box holds 12 cans.She sells 3/4 of the total number of cans for 70p each and the remaining cans for 40p each. WORK OUT THE TOTAL OF PROFIT HE MAKES
Answer:
£3.50
Step-by-step explanation:
The total number of cans Mae bought was ...
(12 cans/box)×(7 boxes) = 84 cans
The revenue from sales is ...
(3/4)(84)(70p) +(1/4)(84)(40p) = 84(3/4×70p +1/4×40p) = 84(52.5p +10p)
= £52.50
The cost of the drinks was ...
(£7/box)×(7 boxes) = £49.00
Mae's profit is the difference between her sales revenue and her cost:
profit = revenue - cost
profit = £52.50 -49.00 = £3.50

There are 4 Year 11 pupils in a football club, out of a total of 29 pupils.
Write this proportion as a percentage.
Give your answer correct to 1 decimal place when appropriate.
Answer:
14%
Step-by-step explanation:
So if we have 4 Year 11 pupils out of a total of 29 pupils at a football club, the fraction for that would be 4/29, if we convert 4/29 into a decimal number we get 0.13793103448, so we round this number up to the nearest 1 decimal place, and that would be 0.14 which equals 14%. Hope this helps.

Solve.
−1.3=x−(−13.2)
What is the solution to the equation?
Enter your answer in the box.
x =
x= -14.5
Step-by-step explanation:
-1.3=x-(-13.2)
the two - signs cross eachother out, making it a +.
making the equation -1.3=x-(-13.2) turn into -1.3=x+13.2.
so you should automatically know your x is going to have to be negative.
What I did:
13.2+1.3=14.5,
but since the 1.3 was actually negative, (-1.3) the 14.5 will turn negative, making it -14.5

What are the advantages of using a table to find equivalent ratios?
What are the advantages of using a graph to find equivalent ratios?
Explain why you prefer a table or a graph to compare equivalent ratios.
The advantage of using a table to determine the equivalent ratio is that, it easier to determine the unknown ratio.
The advantage of using a graph to determine the equivalent ratio is that, it helps to determine the exact value of the unknown ratio.
The use of table to find equivalent ratio makes it easier to determine the unknown ratio. The unknown ratio can easily be determined using interpolation method, this method gives the approximate value of the unknown ratio.
The use of graph to find equivalent ratio helps to determine the exact value of the unknown ratio. This method gives the exact value of the unknown ratio.
The use of table is better because it minimizes error from tracing the values from the graph.

Find ℎ(x) = f(x) − g(x)
Answer:
h(x) = 7x - 3
Step-by-step explanation:
f(x) = 4x − 1 and g(x) = −3x + 2
h(x) = f(x) - g(x)
h(x) = 4x - 1 - (-3x + 2)
h(x) = 4x - 1 + 3x - 2
h(x) = 7x - 3
