What is the slope of the line passing through the points (–1, 3) and (4, –7)?A.) 2

B.) 3/4

C.) -4/3

D.) -2

Answers

Answer 1

Answer: slope=rise/run
slope=(y2-y1)/(x2-x1) if you have the points
(x1,y1) and (x2,y2)

we have the points (-1,3) and (4,-7)
x1=-1
y1=3
x2=4
y2=-7

slope=(-7-3)/(4-(-1))=-10/5=-2

answer is D

10m - 2/5 = 9 3/5

Answers

10m + -0.4 = 9.6
-0.4 + 10m = 9.6
-0.4 + 10m = 9.6
Solving for 'm'Move all terms containing m to the left, all other terms to the right.
-0.4 + 0.4 + 10m = 9.6 + 0.4
Combine like terms: -0.4 + 0.4 = 0.00.0 + 10m = 9.6 + 0.410m = 9.6 + 0.4
Combine like terms: 9.6 + 0.4 = 1010m = 10
Divide each side by '10'.m = 1

Answer:

m = 1

Step-by-step explanation:

10m - 2/5 = 9 3/5

10m = 9 3/5 + 2/5

10m = 9 + 5/5

10m = 9 + 1 = 10

10m = 10

m = 1

There are 20 students in a math class who have brown hair. This represents 80 percent of the students in the class. Which equation can be used to find the total number of students in the math class? mc012-1.jpg mc012-2.jpg mc012-3.jpg mc012-4.jpg

Answers

x=total number of students.
80% of x=20
Therefore, the equaciton can be used to find the total number of students, in the math class is:
(80/100)x=20

We can solve this equation:
(80/100)x=20
x=(20*100)/80=25

Answer: the equation is (80/100)x=20 and its solutions is 25 students.
