Write the equation of a line that goes through the points (4, 8) and (-8, 2)

show work i will appreciate it

Answers

Answer 1
first you have to find the slope by subtracting y2 in this case (2) from y1 (8) dividing it over the subtraction of x2 (-8) and x1 (4) then once you get that you pick a point whether it’s (4,8) or (-8,2), plot it using the slope given to you and you’re done.

Give the following sequence for f(x) = 4x^2 - x , when x is -4, 1, 2
O 58, 14, 3
0-64, - 14, 3
O 68, 14, 3
0 7, 14, 3

Answers

Answer:

O 68, 14, 3

Step-by-step explanation:

Given:

f(x) = 4x² - x

When x = -4

f(x) = 4x² - x

= 4(-4)² - (-4)

= 4(16) + 4

= 64 + 4

f(x) = 68

When x = 1

f(x) = 4x² - x

= 4(1)² - 1

= 4(1) - 1

= 4 - 1

f(x) = 3

When x = 2

f(x) = 4x² - x

= 4(2)² - 2

= 4(4) - 2

= 16 - 2

f(x) = 14

The answer = 68, 3, 14

2. Are you looking for the hypotenuse?

Step-by-step explanation:

Suppose that AKL M is isosceles with base MK.
Suppose also that m 2 M= (3x+36) and m 2 K = (4x +31)
Find the degree measure of each angle in the triangle.
m ZK = 0
m 2L =
m ZM =
MA
K
(3x +36)
(4x +31).
Х

Answers

Answer:

m<K = 51°

m<L = 78°

m<M = 51°

Step-by-step explanation:

Base angles of an isosceles ∆ are equal to each other, therefore,

m<M = m<K

Substitute

3x + 36 = 4x + 31

Collect like terms and solve for x

3x - 4x = -36 + 31

-x = -5

Divide both sides by -1

x = 5

Let's find each degree measure using the value of x

m<K = 4x + 31

Plug in the value of x

m<K = 4(5) + 31

m<K = 20 + 31

m<K = 51°

m<M = 3x + 36

= 3(5) + 36

= 15 + 36

m<M = 51°

m<L = 180° - (m<M + m<K) (sum of triangle theorem)

Substitute

m<L = 180 - (51 + 51)

m<L = 78°

A certain restaurant sells cups of coffee for $2 and donuts for $1.50. If the restaurant sold a total of 80 items and earned $141.50, how many donuts did the restaurant sell?

Answers

Answer: 37 donuts

Step-by-step explanation:

coffee for 2,

donuts for 1.5

c = coffee

d = donuts

lets make an equation

c*2 + (80-c)*1.5 = 141.5

from this we get:

c= 43.

if c = 43, then d is 80-43 = 37.

they sold 43 coffees, and 37 donuts.

lets check the math

43*2+37*1.5 = 141.5. math checks out

Step-by-step explanation:

To find the maximum number of turning points of any polynomial function, subtract one from the degree.

Since the degree is 8, subtract 1 from this:

8 - 1

In order to help students improve their reading, a school district decides to implement a reading program. It is to be administered to the bottom 5% of the students in the district, based on the scores on a reading achievement exam. If the average score for the students in the district is 122.6, find the cutoff score that will make a student eligible for the program. The standard deviation is 18. Assume the variable is normally distributed. Round to two decimal places.

Answers

Answer:

92.99

Step-by-step explanation:

Mean, μ = 122.6

Standard deviation, σ = 18

Recall :

Z = (x - μ) / σ

x = score

The Zscore for the lower 5% = 0.05

Using, invnorm(0.05) = - 1.645

Put Z = - 1.645

-1.645 = (x - 122.6) / 18

-1.645 * 18 = x - 122.6

-29.61 = x - 122.6

-29.61 + 122.6 = x

x = 92.99

These are vertical angles since they are opposite angles made by two intersecting lines. And vertical angles are congruent so we would set them equal to each other.

6x-19 = 3x + 32

Subtract 3x from both sides.

3x - 19 = 32

To isolate 3x on one side add 19 to both sides.

3x= 51

Divide by 3 on both sides.

X = 17
