Sorry if wrong
Answer:
The answer is: 2x+1f(x)=
Step-by-step explanation:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

Which function is the inverse of f(x)=9x-3
Answers
Answer:
The screenshot of my test is below
Step-by-step explanation:
The inverse function is [tex]f^{-1} (x)[/tex]=(x+3)/9.
The given function is f(x)=9x-3.
How to find the inverse of a function?Steps for finding the inverse of a function f(x).
Replace f(x) with y in the equation describing the function.Interchange x and y. In other words, replace every x with a y and vice versa.Solve for y.Replace y with [tex]f^{-1} (x)[/tex].Now, y=9x-3
Interchange x and y. That is x=9y-3.
Solve for y.
That is, 9y=x+3
⇒y=(x+3)/9
⇒[tex]f^{-1} (x)[/tex]=(x+3)/9
Therefore, the inverse function is [tex]f^{-1} (x)[/tex]=(x+3)/9.

Plz help me Jen can jump rope 80 times in 60 seconds. If she jumps at a constant ratio of seconds to jumps, how many jumps can she make in 15 seconds?
Answers
Answer:
The answer is 4
Step-by-step explanation:
You just divide 80 by 15.
She can jump rope 20 times in 15 seconds
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that Jen can jump rope 80 times in 60 seconds.
We have to determine the number of jumps can she make in 15 seconds.
Let the number of jumps would be x she can make in 15 seconds
Since she jumps at a constant ratio of seconds to jumps
So according to proportionality,
⇒ 80/60 = x/15
⇒ x = 15(80/60)
⇒ x = 20
Hence, she can jump rope 20 times in 15 seconds.

The point (-10,4) is on the graph of which of these functions? Select ALL that apply.
Answers
===========================================================
Explanation:
We'll plug x = -10 into each equation shown. If we get y = 4 as an output, then it is one of the answers.
------------------------------
A)
y = -x^2 + 6
y = -(-10)^2 + 6
y = -100 + 6
y = -94
We don't get y = 4, so we cross choice A off the list.
The point (-10,4) is not on y = -x^2+6. Instead, the point (-10,-94) is.
------------------------------
B)
y = (-1/2)*x - 1
y = (-1/2)*(-10) - 1
y = 5 - 1
y = 4
We can see that x = -10 leads to y = 4. The point (x,y) = (-10,4) is on the line. Choice B is one of the answers.
------------------------------
C)
y = (-1/10)*x - 3
y = (-1/10)*(-10) - 3
y = 1 - 3
y = -2
Choice C is not one of the answers since we want y = 4 as an output. So we can cross choice C off the list.
The point (-10,-2) is on the line instead of (-10,4)
------------------------------
D)
y = (1/10)x + 5
y = (1/10)*(-10) + 5
y = -1 + 5
y = 4
Choice D is one of the answers
------------------------------
E)
y = (1/5)*x^2 - 16
y = (1/5)*(-10)^2 - 16
y = (1/5)*(100) - 16
y = 20 - 16
y = 4
Choice E is one of the answers
------------------------------
An alternative method is to graph each equation and see if (-10,4) is on the curve or not. See the diagram below. Only choices B, D and E have (-10,4) on their respective curves.
