Answer:

The solution to the system of equation is (1,-4)

Step-by-step explanation:

Here, we want to find the solution to the system of equations

Since we have y in both places, we can equate the two

That would be;

-x-3 = -7x + 3

-x + 7x = 3 + 3

6x = 6

x = 6/6

x = 1

y = -x - 3

y = -1 -3

y = -4

So the solution to the system of equations is (1,-4)

Step-by-step explanation:

Part A

When dividing 744 ÷ 40, the first digit of the quotient will be in what place?

Hundreds ✔️

Tens  ❌

Ones  ❌

Thousands

Part B

How many apples will be in each basket? Enter your answer in the box.

Apple in each box = 186

Part C

How many apples will be left? Enter your answer in the box.

Apple will be left = 0

Please Tell If Wrong Because I used a piece of paper

There are 18 apples in each basket from the given situation.

Given that, Danielle picks 744 apples at an apple orchard. She divides the apples equally into 40 baskets.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Part A:

744 ÷ 40

40 | 744 | 18

      40

   _____

      344
      320
   _____

       24

The first digit of quotient 18 is in tens place.

Part B:

There are 18 apples in each basket.

Part C:

There are 24 apples will be left.

Therefore, there are 18 apples in each basket from the given situation.

Answer:

The answer is $9.67.

Step-by-step explanation:

Notebooks: 5 * 1.29 = 6.45

Pens: 2 * 1.19 = 2.38

Pencils: 12 * 0.05 = 0.60

Erasers: 6 * 0.15 = 0.90

Total: 6.45 + 2.38 + 0.60 + 0.90 = 10.33

Question:

Which set of ordered pairs (x,y) could represent a linear function?

[tex]\mathbf{A}= \,\,\left\{(2, 9),\,\,(4, 5),\,\,(6, 1),\,\,(7, -1)\right\}[/tex]

[tex]\mathbf{B}= \,\,\left\{(-1, -8),\,\,(0, -3),\,\,(1, 3),\,\,(2, 8)\right\}[/tex]

[tex]\mathbf{C}= \,\,\left\{(-9, 5),\,\,(-3, 3),\,\,(3, 0),\,\,(9, -2)\right\}[/tex]

[tex]\mathbf{D}= \,\,\left\{(1, -8),\,\,(2, -6),\,\,(3, -3),\,\,(4, 0)\right\}[/tex]

Answer:

[tex]\mathbf{A}= \,\,\left\{(2, 9),\,\,(4, 5),\,\,(6, 1),\,\,(7, -1)\right\}[/tex]

Step-by-step explanation:

Given

Ordered pairs A - D

Required

Which represents a linear function?

To do this, we simply calculate the slope (m) of each ordered pairs.

[tex]m = \frac{y_2 - y_1}{x_2-x_1}[/tex]

Considering A:

[tex]\mathbf{A}= \,\,\left\{(2, 9),\,\,(4, 5),\,\,(6, 1),\,\,(7, -1)\right\}[/tex]

Consider the following pairs

[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (4,5)[/tex]

[tex]m = \frac{5 - 9}{4 -2} = \frac{-4}{2} = -2[/tex]

Consider the another pairs

[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (6,1)[/tex]

[tex]m = \frac{1 - 9}{6 -2} = \frac{-8}{4} = -2[/tex]

Consider the another pairs

[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (7,-1)[/tex]

[tex]m = \frac{-1 - 9}{7 -2} = \frac{-10}{5} = -2[/tex]

The slope is uniform all through.

i.e.

[tex]m = -2[/tex]

Hence, this can be a linear function

Considering B:

[tex]\mathbf{B}= \,\,\left\{(-1, -8),\,\,(0, -3),\,\,(1, 3),\,\,(2, 8)\right\}[/tex]

Consider the following pairs

[tex](x_1,y_1) = (-1,-8)[/tex] and [tex](x_2,y_2) = (0,-3)[/tex]

[tex]m = \frac{-3 - (-8)}{0 - (-1)} = \frac{-3 +8}{0 +1} = \frac{5}{1} = 5[/tex]

Consider the another pairs

[tex](x_1,y_1) = (-1,-8)[/tex] and [tex](x_2,y_2) = (1,3)[/tex]

[tex]m = \frac{3 - (-8)}{1 - (-1)} = \frac{3 +8}{1 +1} = \frac{11}{2} = 5.5[/tex]

The calculated slopes are not equal.

i.e.

[tex]m = 5[/tex] and [tex]m = 5.5[/tex]

Hence, this can't be a linear function

Considering C:

[tex]\mathbf{C}= \,\,\left\{(-9, 5),\,\,(-3, 3),\,\,(3, 0),\,\,(9, -2)\right\}[/tex]

Consider the following pairs

[tex](x_1,y_1) = (-9,5)[/tex] and [tex](x_2,y_2) = (-3,3)[/tex]

[tex]m=\frac{3-5}{-3-(-9)} = \frac{3-5}{-3+9} = \frac{-2}{6} = -\frac{1}{3}[/tex]

Consider the another pairs

[tex](x_1,y_1) = (-9,5)[/tex] and [tex](x_2,y_2) = (3,0)[/tex]

[tex]m=\frac{0-5}{3-(-9)} = \frac{0-5}{3+9} = \frac{-5}{12} = -\frac{5}{12}[/tex]

The calculated slopes are not equal.

i.e.

[tex]m = -\frac{5}{12}[/tex] and [tex]m = -\frac{1}{3}[/tex]

Hence, this can't be a linear function

Considering D:

[tex]\mathbf{D}= \,\,\left\{(1, -8),\,\,(2, -6),\,\,(3, -3),\,\,(4, 0)\right\}[/tex]

Consider the following pairs

[tex](x_1,y_1) = (1,-8)[/tex] and [tex](x_2,y_2) = (2,-6)[/tex]

[tex]m = \frac{-6 - (-8)}{2 - 1} = \frac{6 + 8}{1} = \frac{14}{1} = 14[/tex]

Consider the another pairs

[tex](x_1,y_1) = (1,-8)[/tex] and [tex](x_2,y_2) = (3,-3)[/tex]

[tex]m = \frac{3 - (-8)}{-3 - 1} = \frac{3 + 8}{-4} = \frac{11}{-4} = -\frac{11}{4}[/tex]

The calculated slopes are not equal.

i.e.

[tex]m = -\frac{11}{4}[/tex] and [tex]m = 14[/tex]

Hence, this can't be a linear function

From the calculations above:

Only (A) can be a linear function

Answer:

[tex]d - 2 = 7.50[/tex]

$9.50

Step-by-step explanation:

Given that:

Money paid by Mr. Green for a set of dry erase markers = $7.50

Coupon used for the purchase = $2.00

To find:

The equation and solution to represent the difference the original price [tex]d[/tex] of the markers and the coupon.

Solution:

Given that, the original price of the dry erase markers = $[tex]d[/tex]

Coupon amount = $2.00

Amount paid = $7.50

The equation can be made by subtracting the coupon amount from the original price and comparing it with the amount paid by Mr. Green for the purchase.

Original price = $([tex]d[/tex] - 2)

[tex]d - 2 = 7.50[/tex]

Solving the above equation by adding 2 on both the sides:

[tex]d -2+2= 7.50+2\\\Rightarrow d = \$9.50[/tex]

If she paid the store $67.50 (USD) and the membership is 20$ take that 20 and add 2.50 onto it till you get the answer BUT if you want to explain it all the way each month has about 30 days in it so 30x3=90 so she was there for 90 days. 90x$2.50=225 but we all know, she couldn't have rented that many... right? but the final answer is 19, you take 20 from 67.50 which was the membership and all you have to do is fill in that missing amount so take 2.50 and multiply till you get the answer.

Answer and Step-by-step explanation:

To find the surface area, all you have to do is find the area of each face of the prism, and then add them all together.

15 x 20 = 300

(15 x 8)/2 = 60

(15 x 8)/2 = 60

(There are two triangles)

8 x 20 = 160

20 x 17 = 340

Now, add them all together.

300 + 60 + 60 + 160 + 340 = 920

The surface area of the prism is 920 [tex]units^{2}[/tex]

Answer: y = -2x + 9

Step-by-step explanation:

Points through which the line passes through are:  (-2,13) and (4,1)

The slop intercept form will be in terms of:

y = mx + c

Find m first which is the slope:

= (Y₂ - Y₁) / (X₂ - X₁)

= (1 - 13) / (4 - (-2))

= -12 / 6

= -2

Using a point on the line and the slope, calculate c which is the y intercept:

Using point  (-2,13) :

y = mx + c

13 = -2 * -2 + c

13 = 4 + c

c = 13 - 4

c = 9

Slope intercept form of line is therefore:

y = -2x + 9

Answer:

x=17

y=9

Step-by-step explanation:

set 3x-4=5x-38

-2x=-34

x=17

plug x back into equa.= 47 degrees

180-90(right angle)-47=43

7y-20=43

7y=63

y=9

The center for the distribution of scores appears to be higher for subject B than for subject A.

The mean of the distribution when  X represent the score on a randomly selected exam so here the mean be like 2.95.

Since

Column 1 is labeled score with entries 1, 2, 3, 4, 5.

Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.

So it be like

= (0.18) (1) + (0.20) (2) + (0.26) (3) + (0.21) (4) + (0.15) (5)

= 0.18 + 0.40 + 0.78 + 0.84 + 0.75

= 2.95

Hence, the third option is correct.

Step-by-step explanation:

y = 8x² + 8x - 96

y = 8(x² + x - 12)

y = 8(x + 4)(x - 3)

When y = 0, 8(x + 4)(x - 3) = 0.

=> x = -4 or x = 3. (B)

The width of the tower at the top will be 92 m. Then the correct option is B.

The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.

A cooling tower is 120 meters tall.

The sides of the tower are in the shape of a hyperbola defined by the equation x²/500 – y²/900 = 1 with units in meters.

The center of the tower is at the origin.

Then the width of the tower at the top will be

x²/500 – (120)²/900 = 1

x²/500 – 14400/900 = 1

              x²/500 – 16 = 1

                      x²/500 = 1 + 16

                      x²/500 = 17

                              x² = 8500

                                x = 92.19 ≈ 92 m

Then the correct option is B.

2) $12.80

3) $19.20

Step-by-step explanation:

(a) find:  8 is 20% of what number

use proportion:    is   = percent

                            of           100

is = 8

of = what you're solving for, let's say 'x'

20% = 20/100

8  = 20

x       100

cross-multiply:  20x = 800

x = 40

(b)  money spent on fares:  32% of 40 is what number?

32 =   y
