Answer:
y= -1.5x-7 is the equation of the perpendicular line
Here's why:
when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.

Three times a certain number is 21. What is the number?
Answer:
The answer is 7
Step-by-step explanation:
an easier way to think of it is 21 divided by 3, which again, is 7.
Hope That Helps!
Answer:
7
Step-by-step explanation:
Let x be the unknown number
times is multiply and is means equals
3x = 21
Divide each side by 3
3x/3 = 21/3
x = 7
Micheal has 3/4 a cup of milk. This is 1/3 of the amount he needs for a recipe. How much milk is needed for the recipe?
Answer: 2 1/4 cups of milk
Step-by-step explanation:
3/4 times 3 = 9/4 = 2 1/4 cups of milk.
Also you can add 3/4 + 3/4 + 3/4 = 9/4 = 2 1/4 cups of milk
The ratio of the amount of money Karen had to the amount of money Peter had was 2 : 5. After Peter received $75 from his mother, the ratio of the amount of money Karen had to the amount of money Peter had became 4 : 15. How much money did each person have at first?
Answer:
$60 and $150
Step-by-step explanation:
Initially
Karen : Peter = 2 : 5
After Peter receiving $75 the ratio is
4 : 15
We can suppose that initally the amount of monye Karen has is 2x and Peter is 5x.
The new ratio is
2x : (5x +75) = 4 :15
2x (15)= 4 (5x +75)
30 x = 20 x + 300
10 x = 300
x = 30
So at first Karen has 2x =60 dollars while Peter has 5x = 5(3) = 150 dollars.
During a 12-hour period, the
temperature dropped 48º.
How many degrees did the
temperature drop each hour?
Answer:
4 degrees every hour
Step-by-step explanation:
Since it was 48 degrees over a total of 12 hours we can do:
48 / 12 = 4 degrees.
It may be presented as -4 degrees since it is dropping in tempature therefore making it negative.
the area of the parallelogram shown below has an area of 72 units2
Answer:
12 units
Step-by-step explanation:
Allow me to revise your question for a better understanding and I hope it will fit the original one.
The parallelogram shown below has an area of 72 units squared. The base is 6 and the other side is 13 Find the missing height.
Here is my answer:
Given:
The area: 72 units squared.
The base: 6 units
As we know that the area of the parallelogram is represented by below formula:
A = b*h where h is the height and b is the base
In this situation, we know:
72 = 6*h
<=> h = 12
So the missing height is 12 units

a father is 25 years older than his son.Five years ago he was 6 time old as his son was find their presents
Answer:
the present age of the father be x and the present age of the son be y.
It is given that man is 24 years older than his son that is:
x=y+24
x−y=24..........(1)
Also, 12 years ago, he was five times as old as his son that is:
(x−12)=5(y−12)
x−12=5y−60
x−5y=−60+12
x−5y=−48..........(2)
Now subtract equation 1 from equation 2 to eliminate x, because the coefficients of x are same. So, we get
(x−x)+(−5y+y)=−24−48
i.e. −4y=−72
i.e. y=18
Substituting this value of y in (1), we get
x−18=24
i.e. x=24+18=42
Hence, the present age of the father is 42 years and the present age of the son is 18 years.

Find the value of x
. Then find the missing angle measures of the polygon.
Hi there!
Angles in a triangle sum up to 180°, so:
180° = 110° + 5x° + 2x°
Simplify:
180° = 110° + 7x°
Subtract both sides by 110:
70° = 7x°
Divide both sides by 7:
x = 10°
Plug in to solve for the other angles:
5x = 5(10) = 50°
2x = 2(2) = 20°

8x-4=2(4x-4) math question I need the answer to pls help
Answer:
no solutions.
8x-4=2(4x-4)
distribute.
8x-4 = 2*4x+2*-4
8x-4=8x-8
add 4 to both sides
8x= 8x - 4
subtract 8x from both sides
0=-4
this has no solutions, since 0 is not equal to -4.

How do you know each of the sides of the shape are the same length?
Answer:
If your shape is a regular polygon (such as a square in the example above) then it is only necessary to measure one side as, by definition, the other sides of a regular polygon are the same length. It is common to use tick marks to show that all sides are an equal length.
