Answer:

y=-2x-15

Step-by-step explanation:

first find the slope. the formula for finding slope is (y_1 - y_2)/(x_1 - x_2) (rise over run) so we plug in the values and get (-6+4)/(-5+6)= -2/1=-2 so m=-2 and we have y=-2x+b. then plug in either point for x and y and solve for b. -5= -2*-5 +b, -5= 10+b, b=-15, y=-2x-15

Answer:

y=-0.5x-8

Step-by-step explanation:

i got it right

Answer: what’s the question ?

Answer:

2/3

Step-by-step explanation:

the points are (2,-5) and (5,-3)

the slope is change in y over change in x

so the slope can be written as:

(-3-(-5))/(5-2)

thats 2/3

and thats the slope

Explanation:

There are 9 letters in "Metallica", so there would be 9! = 9*8*7*6*5*4*3*2*1 = 362880 different permutations; however, this is only the case if we could tell the letters L and A apart.

We have two copies of each of those repeated letters, so we have to divide by 2!*2! = (2*1)*(2*1) = 4 to account for these repeats.

Because we can't tell the repeated letters apart, we really have (9!)/(2!*2!) = (362880)/(4) = 90720 different permutations.

Step-by-step explanation:

3(2x+1) in this factorize 4 is common .so the answer is 3(2x+1)

Answer:  93, 87 and 87

Explanation:

The given angle is 93 degrees. The angle opposite this is also 93 degrees. Opposite angles of any parallelogram are always the same measure.

Another rule to keep in mind is that: any two adjacent angles add to 180

So if x is adjacent to 93, then 93+x = 180 solves to x = 87. The other two angles, opposite one another, are 87 degrees each.

Answer:

Approximately 17

Step-by-step explanation:

Number of starts getting hidden in 9 hours = 190 - 33

= 157

Therefore the nun of starts getting hidden in 9 hours is 157

9 hours = 157 stars

1 hours = x

Cross multiply

9 × x = 157 × 1

9x = 157

Divide both sides by 9

x = 157 ÷ 9

x = 17.4

Therefore 17.4 stars are getting hidden every hour.

Answer:

17 4/9 stars per hour

Step-by-step explanation:

First find the decrease in the number of stars

190-33 = 157

Divide by the hours that passed

157/9

17 4/9 stars per hour
