Answer:

3/4 or 0.75

Step-by-step explanation:

the equation is in slope-intercept form

y=mx+b

where m is the slope and b is the y-intercept.

you have already found the y-intercept to be -2, so now we just have to find the slope.

slope is also known as rise/run. so if we start at the y-intercept of -2, we can rise (go up) 3 units and then run (go over) 4 units until we reach another point on the line.

so the slope is 3/4 which is also equal to 0.75 units

erastova [34]

Answer:

2,000

Step-by-step explanation:

write out an equation that represents the problem. the original price X fell by 15% to a new price of 1700:

X - (X*15%) = 1700

X(1-0.15) =1700

X=1700/(1-0.15)

X=2,000

convert 15% to decimal form:

15%=0.15

The probability of the given condition is 28/165.

Given that, there are four boys and eight girls in a class.

We need to find the probability of the given question.

<h3>What is probability?</h3>

The probability is defined as the chances of happening of any random event or the possibility of happening of any event is called the probability.

The teacher randomly selects three different students to answer questions.

The first is the student is a girl, the second student is a boy, and the third student is a girl.

The total number of students=12, the number of boys=4 and the number of girls=8.

Now,

Step 1: The first student is a girl=8/12

Step 2: The second student is a boy=4/11

Step 3: The third student is a girl=7/10

In the first step, you select one of 8 girls among 12 students.

In the second step, you select one of 4 boys among the remaining 11 students.

In the third step, you select one of the remaining 7 girls among the remaining 10 students.

Thus, probability=(8/12)×(4/11)×(7/10)=28/165

Therefore, the probability of the given condition is 28/165.

Solve 2 cube root 8x+9=5
Alborosie
2 times the cube root of 8x+9=5
divide both sides by 2
cube root of 8x+9=2.5
cube everybody (put to 3rd power)
8x+9=2.5^3
8x+9=15.625
minus 9 both sides
8x=6.625
divie both sides by 8
x=0.828125
