Answer:

Slope = -1

Step-by-step explanation:

m = y^2 - y^1 / x2 - x1

let (x1, y1) = (-3,4) & (x2, y2) = (2,-1)

m = -1-4 / 2-(-3) = -5/5 = -1

On a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions. The test is worth a total of 100 p

Answer:

The test has 8 questions of 2 points, as well as 16 of 4 points and 4 of 5 points.

Step-by-step explanation:

Since, on a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions, the test is worth a total of 100 points and there are twice as many 2-point questions as 5- point questions on the test, to determine how many 2-point questions are on the test, the following calculation must be performed:

18 x 2 + 9 x 5 + 1 x 4 = 36 + 45 + 4 = 85

16 x 2 + 8 x 5 + 4 x 4 = 32 + 40 + 16 = 88

14 x 2 + 7 x 5 + 7 x 4 = 28 + 35 + 28 = 91

12 x 2 + 6 x 5 + 10 x 4 = 24 + 30 + 40 = 94

10 x 2 + 5 x 5 + 13 x 4 = 20 + 25 + 52 = 97

8 x 2 + 4 x 5 + 16 x 4 = 16 + 20 + 64 = 100

Thus, the test has 8 questions of 2 points, as well as 16 of 4 points and 4 of 5 points.

Solve the system of equations. x + 3y = −12x + 2y = 6

UkoKoshka [18]

Answer:

x=-3/19

y=39/19

Step-by-step explanation:

the equations can be written as the following system

$x+3y=6\\-12x+2y=6$

If the second equation is multiplied by 3/2 it will become -18x+3y=9

If that equation is then subtracted with the first you will obtain the following

-19x=3, it means x=-3/19

The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19

m_a_m_a [10]

Answer:

65.312 inches
326.56 inches
1959.36 inches

Step-by-step explanation:

<h3>Given</h3>

d = 20.8 inches

Travel in 1, 5, 30 rotations

<h3>Solution</h3>

<u>Circumference of the wheel is equal to one full rotation</u>

C = πd = 3.14*20.8 = 65.312 inches
5C = 5*65.312 = 326.56 inches
30C = 30*65.312 = 1959.36 inches
