Graph the linear equation.
y=1/4x​

Answer:

1) $40

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

100      40

1280 = 100y

y = 12.80

3)  40 - (8.0 + 12.80) =  40 - 20.8 = 19.20

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)

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

Change: 20 - 10.33 = 9.67

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:

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.

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:

5/2

Step-by-step explanation:

Answer:

The slope of this line is - 5/2.

Step-by-step explanation:

In order to get from one red dot to another, you must go up 5 and to the left 2, because we are going left instead of right, the slope is negative. It doesn't matter which number you assign the negative sign. The entire formula for the line is y=- 5/2x - 3

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]

Answer:

Required

Determine the expression for s

The speed is calculated as:

[tex]Speed = \frac{Number\ of\ books}{Time}[/tex]

Substitute S for speed

[tex]S= \frac{Number\ of\ books}{Time}[/tex]

Let the number of books be b and the time be m.

The expression becomes

[tex]S = \frac{b}{m}[/tex]

Hence, the expression for the scenario is:

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
