What is 5x-y= -1 in function form????

If by function form you're referencing a y= equation then this is how you do it.
You want the y variable to be alone on its own side, so our first step is to subtract that ugly 5x from the left side.
That gives you -y=-5x-1
Now, we never want the y to be negative so we fix this by multiplying both sides by negative one which will cancel out that negative.
We are then left with y=5x+1

Which of following is an example of a quadratic inequality?

-Dominant- [34]

Answer:

Step-by-step explanation:

Quadratic inequalities are inequalities involving quadratics.

A is not an inequality.

B is an inequality and we can rewrite B as:

$x^2+x$

So, B is a quadratic inequality, and is the answer.

C is not a quadratic. The x terms are not squared.

Likewise, D is not a quadratic either since no x terms are being squared.

Answer:

The answer is Domain = {3,2,5,6,0} and Range = {2,4,-3,-7,0}

Step-by-step explanation:

We have given some points such as (3,2)(2, 4) (5,-3) (6.-7) (0,0)

As we know as the definition of domain is

Domain means the input value we are giving to the function is known to

be the domain of the function

such that y = f(x) .................................................................. (1)

where x is the domain

Range means the output value of the corresponding input such as in

equation (1) we get y value as value of range

Domain of the given problem is {3,2,5,6,0}

Range of the given problem is {2,4,-3,-7,0}

The answer is Domain = {3,2,5,6,0} and Range = {2,4,-3,-7,0}

Can u please help me in number 23 please i don’t know how to do this

This is an example of systems of equations, using weird symbols rather than x or y.

We'll substitute the symbols for the variables d and c

d for diamond, c for clover.

3 + d = c

c + d = 11

We can solve for one variable in the first equation to find the true value of the other variable in the second equation.

3 + d = c

Subtract 3 from both sides.

d = c - 3

Now we have a value for d and can solve the second equation.

c + d = 11

Substitute.

c + c - 3 = 11

Add 3 to both sides.

c + c = 14

Combine like terms.

2c = 14

Divide both sides by 2.

c = 7

Now we know the absolute value of c and can solve for the value of d.

d + c = 11

d + 7 = 11

Subtract 7 from both sides.

d = 4

The diamond, or d, is equal to 4. And the clover, or c, is equal to 7. (This is your answer.)

Let me know if you have any questions.
