Answer:

(y2-y1)/(x2-x1)

Step-by-step explanation:

The slope is the change in y over the change in x

(y2-y1)/(x2-x1)

where ( x1,y1) and (x2,y2) are two points on the line

Answer:

O  A.  [tex]\frac{y2-y1}{x2-x1}[/tex]

Step-by-step explanation:

This is just about how the Slope-Formula works

ok so you get two points off a graph then you use it to plot it in the Slope-Formula like this

for example imma go with (-2, 5) and (3, 7)

I need to subtract 7 - 5 / 3 - -2. so...

m = slope

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

m = [tex]\frac{7-5}{3--2}[/tex]        Only add the denominators when there's 2 - signs together

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

Remark

Find the hypotenuse of the triangle. That is also the length of the rectangle.

Then use Pythagoras to find x.

Givens and solution

two sides of the triangle both = to 6

Find the base of the triangle which is also the length of the rectangle. Call the base = y

6^2 + 6^2 = y^2

36 + 36 = y^2

y^2 = 72

sqrt(y^2) = sqrt(72)

y = 8.4853

Transfer x to the opposite side of the rectangle.

x^2 = diagonal^2 - y^2

x^2 = 9^2 - y^2

x^2 = 81 - 72

x^2 = 9

sqrt(x^2)= sqrt(9)

x = 3

Answer:

$8.5 per hour

Step-by-step explanation:

Number of overtime hours = 4 hours

Since overtime starts after 40 hours, then the number of hours worked = 40 + 4 = 44 hours

Total amount earned = $391

Let Hourly pay = x

Overtime pay = 1 1/2x = 3/2x

Therefore ;

40x + (4*3/2x) = 391

40x + 6x = 391

46x = 391

x = 391 / 46

x = 8.5

Hourly pay = $8.5 per hour

Answer:

4/5

Step-by-step explanation:

There are a total of 10 marbles. Out of those 10 marbles, 8 of them are NOT white. Therefore, the probability of getting a marble that is not white is 8/10 = 4/5.

The probability that a randomly drawn marble is not white is 4/5.

To find the probability that a randomly drawn marble is not white, we need to determine the number of non-white marbles and divide it by the total number of marbles.

In the given bag, there are 10 marbles in total, and 2 of them are white. Therefore, there are 10 - 2 = 8 non-white marbles.

The probability of drawing a non-white marble can be calculated as:

Probability = Number of non-white marbles / Total number of marbles

= 8 / 10

= 4 / 5

Therefore, the probability that a randomly drawn marble is not white is 4/5.

Answer:

Step-by-step explanation:

On Edge

Answer:

diameter [d]=15cm

radius [r]=7.5cm

slant height be l

and

height be h.

lateral surface area of cone =

πrl=477cm²

l=477/(3.1416*7.5)

l=20.244

now

h=[tex]\sqrt{20.2²-(7.5/2)²}=20cm[/tex]

height=20cm.

LSA of cone = πrl = 477cm²

L = 477/(3.1416 × 7.5)

L = 20.244

Height (h) = √{20.2²-(7.5/2)²}

h = 20cm

Answer:

y = -3/8x -41/8

Step-by-step explanation:

Perpendicular lines intersect at 90° and their slopes are opposite reciprocals.

Therefore the slope changes from 8/3 to -3/8.

Now we must solve for the new y-intercept (b) by plugging in the given coordinate (-3,-4).

The result is b = -41/8 so our new equation is:

y = -3/8x -41/8

Answer: 3.33% (choice B)

===================================================

Work Shown:

A = true value = 60

B = estimated or measured value = 62

C = percent error

C = ( |A-B|/A ) * 100%

C = ( |60-62|/60 ) * 100%

C = (2/60)*100%

C = 0.0333*100%

C = 3.33%

The result is approximate.

Answer:

Step-by-step explanation:

The larger triangle is a scaled version of the smaller one since all the angles are the same. Just the sides are different.

All angles are same: vertical angles are the same, right angles in both triangles, the last angle in both triangles have to be the same if the other angles were the same.

The side proportions are the same.

Answer:

[tex]y=2x+5[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)

1) Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (-3,-1) and (1,7)

[tex]m=\frac{7-(-1)}{1-(-3)}\\m=\frac{7+1}{1+3}\\m=\frac{8}{4}\\m=2[/tex]

Therefore, the slope of the line is 2. Plug this into [tex]y=mx+b[/tex]:

[tex]y=2x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=2x+b[/tex]

Plug in one of the given points and solve for b

[tex]7=2(1)+b\\7=2+b[/tex]

Subtract 2 from both sides to isolate b

[tex]7-2=2+b-2\\5=b[/tex]

Therefore, the y-intercept is 5. Plug this back into [tex]y=2x+b[/tex]:

[tex]y=2x+5[/tex]

Answer:

no

the goal total would be too high

Step-by-step explanation: If Sadie had scored 4 goals, Connor would have scored 2 times 4 = 8 goals. Their goal total would then be 4+8 = 12, not 9. Sadie cannot have scored 4 goals.

__

If we let s represent the number of goals Sadie scored, then 2s is the number Connor scored. Their total is ...

 s + 2s = 9

 3s = 9 . . . . . . collect terms

 s = 9/3 = 3 . . . divide by the coefficient of s

Sadie scored 3 goals. (s=4 is not the solution to the problem)
