Answer:

The answer would be true

Step-by-step explanation:

Since there is only one y for every value  of x and only one x for every value of y, both this graph and it's inverse would both be functions.

Answer: I believe it is a. Sorry if I am incorrect

Step-by-step explanation:

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

Answer:

[tex]y = 2x + 2[/tex]

Step-by-step explanation:

The equation of any (non-vertical) line can take the form

y = ax + b where a is the slope and b is the y intercept. We know that in this case, the y intercept is 2. So we can substitute b = 2:

[tex]y = ax + 2.[/tex]

Now, to find the x intercept, simply put y = 0 (since every point on the x axis has y = 0) and x = -1, since that is the given x intercept:

0 = -a + 2, so we see that a = 2. The equation is then:

y = 2x + 2

Answer: 36.56

Step-by-step explanation:

To solve the equation, first acknowledge that the radius of the quarter circle shown at the top of the figure is 4 cm, so the rectangle's dimensions are 4 by (10-4) or 4 by 6, meaning the area is 24 cm^2.

Then address the circle, with an area of pi * r^2.

pi * r^2

3.14 *(4)^2

3.14 * 16

50.24

Then, because the figure shows 1/4 of a circle, divide 50.24 by 4.

50.24/4

12.56

Then add 24 to 12.56 to get 36.56.

Hope it helps :) and let me know if you want me to elaborate.

Okay,

So this equation is non existent. It is not an equation nor expression.

Answer:

y=11

Step-by-step explanation:

Hi there!

We want to find the equation of the line that passes through the point (-8, 11) and is perpendicular to x=-15

If a line is perpendicular to another line, it means that the slopes of those lines are negative and reciprocal; in other words, the product of the slopes is equal to -1

The line x=-15 has an undefined slope, which we can represent as 1/0, which is also undefined.

To find the slope of the line perpendicular to x=-15, we can use this equation (m is the slope):

[tex]m_1*m_2=-1[/tex]

[tex]m_1[/tex] in this instance would be 1/0, so we can substitute it into the equation:

[tex]\frac{1}{0} *m_2=-1[/tex]

Multiply both sides by 0

[tex]m_2=0[/tex]

So the slope of the new line is 0

We can substitute it into the equation y=mx+b, where m is the slope and b is the y intercept:

y=0x+b

Now we need to find b:

Since the equation passes through the point (-8,11), we can use its values to solve for b.

Substitute -8 as x and 11 as y:

11=0(-8)+b

Multiply

11=0+b, or 11=b

So substitute into the equation:

y=0x+11

We can also write the equation as y=11

Hope this helps!

Answer:

m∠CAB = 40°

Step-by-step explanation:

DAC = 99

DAB = 59

B is inside DAC, and so is DAB. So CAB must add to 59 to get to 99, nothing over that because it's inside DAC.

So 99 - 59 = 40

CAB must be 40°

That's all I can say for now. Hope this helps and a thank won't hurt! :)
