Answer:

  f^-1(x) = -2(x +5)

Step-by-step explanation:

Solve for x.

  y +5 = -1/2x . . . . . add 5

  -2(y +5) = x . . . . . multiply by -2

If you want this in "functional form", you can write it as ...

  f^-1(x) = -2(x +5) . . . . . swap x and y, then use f^-1(x) for y

Answer:

slope = 5

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, - 3) and (x₂, y₂ ) = (- 3, 2) ← 2 points on the line

m = [tex]\frac{2-(-3)}{-3-(-4)}[/tex] = [tex]\frac{2+3}{-3+4}[/tex] = [tex]\frac{5}{1}[/tex] = 5

Answer:

The equation is;

y = 20x + 150

Step-by-step explanation:

Firstly, let us identify the coordinates

(area, cost of area)

We start by getting the points;

(25,650) and (40,950)

The slope will be;

m = (y2-y2)/(x2-x1)

m = (950-650)/(40-25)

m = 300/15 = 20

So the partial equation is;

y = 20x + c

To get the value of c which is the y-intercept, we make use of any of the two points

650 = 20(25) + c

650 = 500 + c

c = 650-500

c = 150

Answer:38

Step-by-step explanation:y= 19x

                                           y=19(2)

                                           y=38

                                  You plug in x as 2 since when x=2 .and u do 19 times 2 which gives you 38 .

Hope it helps u ;)

Answer:

down 2, right 1

Step-by-step explanation:

Here, we want to know what -2 means for the slope

The following conventions are necessary to be known;

down is negative

left is negative

up is positive

right is positive

Thus;

Since the slope is actually vertical change/ horizontal;

The 2 value must be in respect to the y-axis

Hence;

up 2 right 1 is positive

down 2 left 1 is positive since both are negatives

The correct answer is thus;

down 2, right 1

Answer:

Quotient = 3

Step-by-step explanation:

We need to solve the given expression :

[tex]\dfrac{\dfrac{12}{x-4}}{\dfrac{4}{x-4}}[/tex]

It can be done as follows :

As, [tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]

So,

[tex]\dfrac{\dfrac{12}{x-4}}{\dfrac{4}{x-4}}=\dfrac{12}{x-4}\times \dfrac{x-4}{4}\\\\=\dfrac{12}{4}\\\\=3[/tex]

Hence, the required quotient is 3.

Answer:

100

Step-by-step explanation:

So in this problem, we have 5 base 10 blocks and 50 ones.

To find out the product we have to count by tens:

10, 20, 30, 40, 50

So 5 base 10 blocks = 50

Now we add the base ten blocks and the ones together:

50 + 50 = 100

So the answer is 100

Answer:

180- 148 = 32 (the measure of the angle thats supplementary to the exterior

Answer:

We need to find the number of shirts he sold using: 15s - 100 = 350

s = 30

So, Rory sold 30 shirts :)

The required expression that defines the scenario is 15s - 100 = 350 and the number of t-shirts sold is 30. Option D is correct.

Given that,
Rory sold T-shirts at a festival for $15 each. He paid $100 in materials and fees. Rory's profit after the festival was $350. He wants to know how many shirts he sold.

According to the assertions, it deals with a number of operations in mathematics. Addition, subtraction, multiplication, and division are the four main arithmetic operators.

Here,
Let the number of the t-shirts be s,
According to the question,
Total cost of s t-shirts = 15s
He spends $100 on materials,
Profit = 15s - 100
15s - 100 = 350

Thus, the required expression that defines the scenario is 15s - 100 = 350 and the number of t-shirts sold is 30. Option D is correct.

Answer:

       0.59 < 0.6

14.807 < 14.087

Step-by-step explanation:

all the bolded ones are correct

The correct comparisons are 0.59 < 0.6, 6.580 = 6.58 and 4.59 < 4.598.

Decimals are types of real numbers where the fractional number is simplified by base-10 number system. It involves a whole number part and a decimal part separated by a decimal point.

Any whole number 'a' can be written as decimal as a.00...

The first place value after the decimal point is called tenths, second value is called hundredths, third value is called thousandths and so on.

The comparison 0.59 < 0.6 is true, since the tenths of 0.59 is 5 which is less than the tenths of 0.6, which is 6.

The comparison 6.580 = 6.58 is also true, since the zeroes on the last after decimal point have no value.

The comparison 33.54 < 33.504 is false, because the hundredths of 33.54, 4, is greater than the hundredths of 33.504 which is 0.

The comparison 14.807 <14.087 is false, because tenths of 14.807 is 8 which is greater than the tenths of 14.087, which is 0.

The comparison 4.59 < 4.598, because the thousandth of 4.59 can be told as 0 which is less than the thousandths of 4.598, which is 8.

Hence  0.59 < 0.6, 6.580 = 6.58 and 4.59 < 4.598 are the correct comparisons given.
