Hi there!

The graph is a relation.

It doesn't pass the Vertical Line Test. This test is just a vertical line.

If it touches the graph once, then the graph is a function.

If it touches the graph more than once, then the graph is a relation.

Here, the vertical line touches the graph more than once, so the graph is a relation.

Type: no

Therefore, our answer is: no

Hope this helps!

At Health Hair, the cost of a children's haircut, x, is $4 and the cost of an adult haircut, y, is $14. The sales from Friday were $568. There were 42 haircuts in all.

Write a system to represent the situation and solve the system and interpret the answer.

Answers

Answer:

x + y = 42

4x + 14y = 568

x = 2, y = 40

Step-by-step explanation:

x + y = 42

4x + 14y = 568

to solve, you can let 'x' = 42-y and substitute this expression for 'x' in the second equation to get:

4(42-y) + 14y = 568

168 - 4y + 14y = 568

168 + 10y = 568

10y = 400

y = 40

therefore, x = 2

check:

4(2) + 14(40) should equal 568

8 + 560 = 568

standard form.

Answers

Answer:  2r² - 5r + 4

Step-by-step explanation:

Since expression = 3A + 2B                             [subsitute in values of A&B]

       ⇒                  = 3(r – 2) + 2(r² – 4r + 5)     [expnad the brackets]

                            = 3r - 6 + 2r² - 8r + 10           [group like terms ins stan. form]

                            = 2r² - 8r +  3r + 10 - 6         [simplify like terms]

Step-by-step explanation:

Since ∠AGF is 67° the that would mean that ∠GFE is also 67°, and since it is a Trapezoid, all the angles should add up to 360°. So we have both of the 67's so that means we have 67+67, and the other two angle need to be the same, but to find those we need to do 67+67 = 134, and 360-134=226, and half of 226 will be 113, which is the angle for both of the missing angles, and is the missing angle u are looking for

There is a line that includes the point (0, 4) and has a slope of 9. What is its equation in
slope-intercept form?

Answers

Answer:

y = 9x + 4

Step-by-step explanation:

The slope-intercept equation is

y = mx + b

M = slope

B = y-intercept.

From the point, we know the line intercepts y at 4. So the y-intercept is 4.

Now the slope is 9.

Now insert the numbers:

y = 9x + 4
