Does this graph show a function? Explain how you know.
• A. Yes; the graph passes the vertical line test.
• B. No; there are y values that have more than one x-value.
• C. No; the graph fails the vertical line test.
• D. Yes; there are no y-values that have more than one x-value.

#1

No

#2

We can see f(1) has 3 values so it's not a function as it's failed in vertical line test

#3

f(10) has two values -2 and 11

So not a function

#4

As per definition of function

So it's not a function

Answer:

Step-by-step explanation:

Let "a number" be x.

"3/7 of a number" means (3/7)x

"32 less" means - 32

Thus, "32 less than 3/7 of a number" means (3/7)x -32

"is 11/35 of that number" means = (11/35)x

Put these together and we get:

(3/7)x -32 = (11/35)x

(3/7)x - (11/35)x = 32   Rearrang to get the x on one side

We need to change "(3/7)x - (11/35)" so that the two terms have a common denominator.

If we multiply the first term by (5/5) [which is equal to 1], we get:  

(5/5)(3/7)x or

(15/35)x

We can now write:

(15/35)x - (11/35)x = 32

(4/35)x = 32

Multiply both sides by (35/4)

(35/4)(4/35)x = (35/4)(32)

x = (35)(8)

x = 280

so first

Tan 60 = Perpendicular / 11√6

Perpendicular = 1.732 (11√6)

Perpendicular = 46.66

Then,

Step-by-step explanation:

Every multiplication fact is equivalent to two (2) division facts:

The value of x from the given equation is 5/3

Since the three points are collinear to U, they are on a straight line which equals 0

Then we have,

Collect like terms

5x + 10x + 50 = 3x + 80

15x - 3x = 80 - 50

12x = 30

Jorge will receive 9 hours in time off from work.

How many hours will Jorge get to take time off?

It is given that, Jorge has done overtime for 6 hours in this week. As per the Fair Labor Standards Act, for 6 hours of overtime work, he must be paid one and a half times the pay he gets per hour.

Instead of receiving an overtime pay for working 6 hours extra, Jorge decides to receive paid leaves from work, that is, he will get one and a half of the total hours for which he worked overtime.

As a result, the time off he receives from work = [tex]1\frac{1}{2} (6)[/tex] hours

[tex]=\frac{3}{2}(6) = 9 hours[/tex]

Thus, Jorge gets 9 hours in time off from work in return. The time that he earns for the overtime is equivalent to the pay he was supposed to receive for the overtime work.

The inverse of any function F(x) is also a function.

A function is an abecedarian notion in mathematics and computer programming. In both contexts, a function is a regulation or relationship that maps input values to corresponding output values. It takes one or more input values, performs a set of operations or calculations, and produces a single output value.

There are many types of functions such as trigonometric function, logarithmic function, exponential function, and so on.

If a function f(x) gives output y then its inverse will be [tex]f^{-1}(y)[/tex] and will return x as output.

Answer:

The 2 numbers are 3 and 5.

Step-by-step explanation:

x + y = 8

1/x + 1/y = 8/15

From first equation  y = 8 - x so

1/x + 1 / (8-x) = 8/15

Multiply through by the LCM 15x(8-x):-

15(8 - x) + 15x =  8x(8-x)

120 - 15x + 15x = 64x - 8x^2

8x^2 - 64x + 120 = 0

x^2 - 8x + 15 = 0

(x - 3)(x - 5) = 0

x = 3 or  5

so y = 8-3 = 5 or 3.

K = 27°

Step-by-step explanation:

c = 27°

since C is opposite K, K = 27°

Since 55° is opposite P, P = 55°

Lets start by moving 6 over to the other side. We can do this by subtracting 6 from both sides of the equation.

7x+6-6=160-6

7x=154

Now, let's isolate x by getting rid of the 7. The 7 is being multiplied with x, so to get rid of it we have to divide both sides by 7.

7x/7 = 154/7

Answer:

1/5

Step-by-step explanation:

The slope-intercept form looks like [tex]y=mx+b[/tex] where b is the y-intercept and m is the slope. m is the slope because if you increase x by 1, the value y increases by m, and if you increase x by 1 again, the y-value will increase by the value of m, because it's being multiplied. b is the y-intercept since the y-intercept is when x=0 so mx will become m(0) which is just 0 leaving b by it self. In this case you have y=1/5x so if you were to start with 0 as x the value of y is 0. Now increase it by 1 so x becomes 1, the value of y becomes 1/5x, now increase it by 1 again so x becomes 2, the value of y is 2/5x, so as you can see the function is just increasing by 1/5 so that's the slope, so essentially whatever the coefficient of x is (the number in front of the variable x), is the slope

Given:  [tex]\textsf{y = 1/5x}[/tex]

Solution:  In order to determine the slope of the line we need to see how the slope-intercept form compares to this expressions.  The slope-intercept form is y = mx + b where m is the slope and b is the y-intercept.  In this case we have no y-intercept therefore we do not have a b. However, our slope is equal to 1/5 as it fits perfectly with the form that was provided.
