Answer 1

The function above is only true for exactly one x value, so B is your answer.

Notice that the output of the function is y=7. This means that there is one x value that will make this equation true. If there were multiple x values that made it true, the output would simply be just y. When there is a specific output, you can solve for x and figure out that there is one output for that input.

Find the equation of AB using the coordinates of the endpoints:

A(- 1, - 1), B(2, 3)

Find the slope:

m = (3 - (-1)) / (2 - (-1)) = 4/3

Use one of the points and point-slope equation to get the line:

y - 3 = 4/3(x - 2)y - 3 = 4/3x - 8/3y = 4/3x + 3 - 8/3y = 4/3x + 1/3

Now find the y - coordinate of F when x is 5:

y = 4/3*5 + 1/3y = 20/3 + 1/3y = 21/3y = 7

Part B can't be solved as the picture is unclear

Sophie buys milk and vegetables at the grocery store. She spends $3.29 on milk and has a total bill of $15.56. Write and solve an equation to determine how much Sophie spent on the vegetables.

Answers

Answer: $12.27

Step-by-step explanation:

She spent a total of $15.56

Vegetables cost $12.27

Milk cost $3.29

Subtract the total bill by the amount of the milk and you have the total for the vegetables which is $12.27

6) An expression is given.
X2+zx-12
The expression can be written as (x+q) (x+r) where q, r, and z are integers.
What are possible integer values or q, r, and z?

Answers

Expressions are mathematical statements without the equation sign

The possible integer values of q, r, and z are 3, -4 and -1

How to determine the values of the integers

The expressions are given as:

x^2 + zx - 12

(x + q)(x + r)

Both expressions are equal.

So, we have:

[tex]x^2 + zx - 12 = (x + q)(x + r)[/tex]

Expand

[tex]x^2 + zx - 12 = x^2 + (q + r)x + rq[/tex]

By comparison, we have:

[tex]q + r = z[/tex]

[tex]rq = -12[/tex]

Assume that q = 3.

So, we have:

[tex]3r = -12[/tex]

Divide by 3

[tex]r = -4[/tex]

Recall that:

[tex]q + r = z[/tex]

So, we have:

[tex]z = 3 -4[/tex]

[tex]z = -1[/tex]

Hence, the possible integer values of q, r, and z are 3, -4 and -1

By solving given equation and then finding discriminant we get that this system of equations have 2 solutions

What is system of equations?

Collection of two or more equations with a same set of unknowns is called system of equations.

Given equation

[tex]$$y=-2 x+2\ \ ...(1)\\\\y=x^{2}-3 x$$\ \ \ ...(2)[/tex]

From equation (1) and (2)

[tex]x^{2}-3 x=-2 x+2\\\\x^{2}-3 x+2 x-2=0\\\\x^{2}-x-2=0[/tex]

This is a quadratic equation

So discriminant

[tex]D=b^2-4ac[/tex]

[tex]D=(-1)^2-4(1)(-2)\\D=1+8\\D=9[/tex]

As D is >0 so we will get two values of x

and two values of y corresponding to values of x

By solving given equation and then finding discriminant we get that this system of equations have 2 solutions

Square ABCD is similar to square EFGH. The ratio of AB:EF is 1:4. The area of square EFGH is 14,000ft^2. What is AB?

Answers

Answer: 5sqrt(35)

Step-by-step explanation:

If the ratio of the side lengths is 1:4, since the ratio of the areas is the square of the ratio of the side lengths, the ratio of the areas is 1:16.

This means the area of square ABCD is 14000/16 = 875.

Therefore, AB=sqrt(875)=5sqrt(35).

one number is 8 more than a second number. 4 times the first is 8 less than 6 times the second. find the numbers

Answers

The numbers are 20 and 28.

Step-by-step explanation:

Let the number be X and y,

X = 8 + y

4x = 6y - 8

Now,

4x = 6y - 8

or, 4(8 + y) = 6y - 8

or, 32 + 4y = 6y - 8

or, 32 + 8 = 6y - 4y

or, 2y = 40

so, y = 20

now,

X = y + 8 = 20 + 8 = 28

Answers

Answer: 30

Step-by-step explanation:

Let the middle number = x. Then the three consecutive numbers are x - 1, x, and x + 1.

3x = 93

x = 31.

The smallest of the 3 numbers is x - 1 = 31 - 1 = 30
