The points on the graph of the inverse variation are of the form:

(x, 8/x)

An inverse variation function is written as:

y = k/x.

Here we know that k = 8.

y = 8/x

Then the points (x, y) on the graph of the function are of the form:

(x, 8/x).

So evaluating in different values of x, we can get different points on the graph:

Answer: Second option from the top

Step-by-step explanation:

   First, we will simplify the given inequalities.

2x + 7 ≥ 1

2x ≥ -6

   x ≥ -3

-

8 - [tex]\frac{x}{3}[/tex] ≤ 5

- [tex]\frac{x}{3}[/tex] ≤ 5

- [tex]\frac{x}{3}[/tex] ≤ -3

   x ≥ 9

   Now, we will graph them. See attached.

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

The probability that a randomly selected customer will order a chicken sandwich or french fries is 36%

The given parameters are:

P(Chicken) = 56%

P(Sandwich) = 43%

P(Both) = 30%

The required probability is:

P = P(Chicken) + P(Sandwich) - P(Both)

This gives

P = 56% + 43% - 30%

Evaluate

P = 36%

Hence, the probability that a randomly selected customer will order a chicken sandwich or french fries is 36%

Answer: x = 15

Step-by-step explanation:

Hi!

These are supplementary angles, which means they both add up to 180°

Therefore,

9x+10 + 1x + 20 = 180

to solve, combine like terms

10x + 30 = 180

Then subtract 30 from both sides

10x = 150

now divide 10 from both sides leaving x by itself

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

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.

Let x be the number of pencils bought.

Let y be the number of pens bought.

Given information from the question:

x = y - equation 1

2.9y - 1.2x = 32.30 - equation 2

From here we can use the substitution method in solving simultaneous equations to find x and y. We will substitute equation 1 into equation 2.

2.9y - 1.2y = 32.30

1.7y = 32.30

y = [tex]\frac{32.3}{1.7} \\= 19[/tex]

153° + c = 180°

c = 27°

since C is opposite K, K = 27°

Answer:

A. y<-1/5x+1

Step-by-step explanation:

First, find the slope of the line

delta y / delta x = slope (delta means "change in", so delta y would the the change in y)

the change in y is 1, and the change in x is -5, so the slope is -1/5

we now know that the equation of the line is
y=-1/5x+1

The answer can't be c or d, because the line is dotted and not solid (solid lines signify ≥ or ≤, and dotted > and <)
To test if it is > or <, we can plug in some numbers to see if the equation is true

Right now, we have:

y[?]-1/5x+1, where "[?]" is either > or <

we see that the point 0,0 is a solution, since it is in the shaded region of the graph, because of this, we know that if we plug x=0 and y=0 into the equation, it must be true

plug in:

0[?]-(1/5)*0+1

0[?]1

clearly, [?] should be <, as 0<1
so, now that we know [?], we can replace it in our equation

y<-1/5x+1 , or "A"

We can write this as a conversion factor.  Either:

 1)  1cm/10mm, or

 2) 10mm/1cm

We are given 136 mm.  Convert that by using either conversion factor.

(136mm)*(1cm/10mm) = 13.6 cm  Note how the mm unit cancels.

To use the other conversion factor, do a division:

(136mm)/(10mm/1cm) = 13.6 cm
