Which of the following statements is not true about the graph of a system of equations with infinitely many solutions? please answer correctly!
Answers
Answer:
The lines will have one positive y-intercept and one negative y-intercept is not true about the graph of a system of equations with infinitely many solutions.
Step-by-step explanation:
A system of equations with infinitely many solutions suggests on the graph, the equations will appear to be the same (they will look like one graph) because all points on each equation are equal. This suggests that it's impossible for the y-intercepts to be different, which is why the "lines will have one positive y-intercept and one negative y-intercept " is a false statement.

A function is shown g(x)=96.2(4)(x+2.5). The function g can be rewritten as the function h in the form h(x)=a(4)x. What is the value of a in the function h(x)?
I already know the answer, but I need the step-by-step. Thank you!
Answers
Answer:
96.2+240.5/x
Step-by-step explanation:
g(x)=96.2(4)(x+2.5)
h(x)=[96.2(x+2.5)](4)--------------Calculate[96.2(x+2.5)] first
h(x)=(96.2x+240.5)(4)
h(x)=x(96.2+240.5/x)(4)----------bring out X,So 96.2x+240.5 is divided by x
h(x)=(96.2+240.5/x)(4)x
h(x)=a(4)x
so a=96.2+240.5/x
The value of a is 96.2 + 240.5/x.
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).
Given g(x) = 96.2(4)(x+2.5),
and h(x) = a(4)x,
to find a
h(x) = [96.2(x + 2.5)](4)--------------Calculate[96.2(x+2.5)] first
h(x) = (96.2x + 240.5)(4)
h(x) = x(96.2 + 240.5/x)(4)--------bring out x,So 96.2x+240.5 is divided by x
h(x) = (96.2 + 240.5/x)(4)x
h(x) = a(4)x
so a = 96.2 + 240.5/x
Hence value of a = 96.2 + 240.5/x

Step-by-step explanation:
QUESTION A:
Find the GCD (or HCF) of numerator and denominator
GCD of 15 and 30 is 15
Divide both the numerator and denominator by the GCD
15 ÷ 15
30 ÷ 15
Reduced fraction:
1/2
Therefore, 15/30 simplified to lowest terms is 1/2.
Thus, option d is your answer
QUESTION B:

Jill and Kyle get paid per project. Jill is paid a project fee of $45 plus $10 per hour. Kyle is paid a project fee of $20 plus $14 per hour. Write an expression to represent how much a company will pay to hire both to work the same number of hours on a project.
Answers
We will be using (h) to represent the amount of hours. For Jill, the expression will be 45+10h and for Kyle the expression will be 20+14h. Fee+hourly pay x hours.
To get the total amount the company will pay to hire both Jill and Kyle, you must combine both of their expressions. So 45+20= 65, and 10+14=24. So now the expression= 65+24h
So the answer is that the company will be paying 65+24h dollars to hire both Jill and Kyle:)
