A ladder is 78 inches tall. How tall is it in feet and inches?

Answer:

Let's put this function into slope-intercept form.

y = mx + b

where m is the slope

and b is the y-intercept

We know the y intercept is -3 since f(0) = -3

Thus, b = -3

To find the slope, use the equation m = (y1 - y2) / (x1 - x2)

x1 = 0

y1 = -3

x2 = 7

y2 = 11

Note: these values came from the given information

m = (-3 - 11) / (0 - 7)

= (-14) / (-7)

= 2

m = 2

Plug the values of m and b into y=mx + b

y = 2x - 3

That's your answer.

Answer:

160 students

Step-by-step explanation:

As, 80% of 200 students instruments are of brass

So 80% of 200

= 80/100 x 200 = 160

So 160 students

Answer: 1 & 5 are both corresponding angles

Step-by-step explanation: because they are both on the top and on the same side that's what makes them corresponding angles

Answer: ):

Step-by-step explanation:

Answer:

second side is 16

third side is 38

Step-by-step explanation:

x + (x - 8) + (x + 14) = 78

3x + 6 = 78

3x = 78 - 6

3 x = 72

x = 72/3

x = 24

24 + (24 - 8) + (24 + 14) = 78

24 + 16 + 38 = 78

Answer:

[tex]y = \frac{1}{3}x + 5[/tex]

Step-by-step explanation:

Slope (m) = 1/3

(-3 , 4)

y - y1 = m(x -x1)

y - 4 = (1/3) (x - [-3])

[tex]y - 4 = \frac{1}{3}(x + 3)\\\\y - 4 = \frac{1}{3}x + \frac{1}{3}*3\\\\y - 4 = \frac{1}{3}x + 1\\\\ y = \frac{1}{3}x + 1 + 4\\\\ y = \frac{1}{3}x + 5[/tex]

Answer:

-4

Step-by-step explanation:

Step-by-step explanation:

Given

-6x + 9 = 33

or -6x = 33- 9

or, - 6x = 24

or - x = 24 / 6

or, - x = 4

Therefore x = - 4.

Answer:

4

Step-by-step explanation:

solved it

Answer:

m = 4

Step-by-step explanation:

m = (y2 - y1) / (x2-x1)

Given points (6,11) and (8,19) Let y2 = 19, y1 = 11, x2 = 8, and x1 = 6

Subbing in

m = (19-11)/(8-6) = 8/2 = 4

So, the slope is 4

Step-by-step explanation:

Answer:

1) Reflections just change the signs of the coordinates, so (1.5, -2) and (-1 and 1/2, 2) are reflections of each other. Also (1.75, -4) and (-1 and 3/4, 4)

2) From left to right: -1.75, -3/4, 1/4, 0.75, 1 and 1/2.

Remember that each 1/4 = 0.25, so this could help you work out fractions and decimals.

Answer:b

Step-by-step explanation:

Answer:

Let x represent the number of games they lost. Then they won 24 + x games. Since the team played 70 games, x + (24 + x) = 70. Thus 2x + 24 = 70. Dividing both sides of the equation by 2, we have x + 12 = 35. Hence, x = 35 - 12 = 23.

Answer:

Alison Bender and Income Tax Returns

The probability that fewer than 2 of the returns contains errors is:

8.333%

Step-by-step explanation:

a) Data and Calculations:

Number of income tax returns filed by Alison = 12

Number of returns with minor errors = 2

Percentage of returns with minor errors = 2/12 = 16.67%

Random sampling of returns by Alison's manager = 3/12 = 25%

Fewer than 2 = 1

The probability of 1 error in 12 returns = 1/12 = 0.08333

= 8.333%

b) Since Alison's manager randomly selects three returns from the 12 to check for errors, the probability of discovering the errors is 25% (3/12).  However, the probability that less than 2 contains errors = 8.333% (1/12).

Answer:

-24.35, -7.96, 11.20

Step-by-step explanation:

Negative numbers are worth way less than positive numbers. In order to solve, the biggest looking negative number is worth less.

Positive is bigger

Negative is smaller

*EXTRA*

negative plus negative = positive

negative plus positive = negative

negative times negative = positive

negative times positive = negative
