What is an equation of the line that passes through the points (-8,-6) and (3, – 6)?

Mathematics

Maksim231197 [3]3 years ago
6 0

Answer:

y=-6

Step-by-step explanation:

The y value isn't changing when the x value does. This means there is no rate of change or gradient. So in y=mx+c m=0 so we get y=c, c is always -6.

The number of students who passed on the math exam was three-fourths of the total number of students who failed.
Alexxandr [17]

Answer:

one quarter of the total number of students will be those who failed their exam.

Step-by-step explanation:

Three - fourths = those who passed the exam

one quarter will be those who failed their exam

From the total number of the students.

Let's make an example

40 students who take the exam.

3 over 4 students from the total number of 40 take the exam and the result is passed and it mean 30 students passed in the exam.

1 over 4 students take the exam and the result is failed and it mean 10 students failed in the exam.

4 minus 3 over 4 will get the answer 1 over 4.

Use 1 over 4 to multiple with the total number of the students and that how you will get the answer for those who failed in their exam.

Can anyone help me on this problem? Please it doesn’t make sense to me...
Sav [38]

Answer:

6

Step-by-step explanation:

Cost per item is found by dividing the cost by the number of items. If the woman bought n items for $120, the cost of each item is $120/n. If the woman bought 24 more items, n+24, at the same price, then the cost per item is $120/(n+24). The problem statement tells us this last cost is $16 less than the first cost:

120/(n+24) = (120/n) -16

Multiplying by n(n+24) gives ...

120n = 120(n+24) -16(n)(n+24)

0 = 120·24 -16n^2 -16·24n . . . . . . subtract 120n and collect terms

n^2 +24n -180 = 0 . . . . . . . . . . . . . divide by -16 to make the numbers smaller

(n +30)(n -6) = 0 . . . . . . . . . . . . . . factor the quadratic

The solutions to this are the values of n that make the factors zero: n = -30, n = 6. The negative value of n has no meaning in this context, so n=6 is the solution to the equation.

The woman bought 6 items.

_____

Check

When the woman bought 6 items for $120, she paid $120/6 = $20 for each of them. If she bought 6+24 = 30 items for the same money, she would pay $120/30 = $4 for each item. That amount, $4, is $16 less than the $20 she paid for each item.
