To make the equation go through (0,-4) the new equation would be 9x + 5y = 20. We needed to change it from subtracting to adding so the direction of the line would go from going down to up too up to down. In slope-intercept form the original equation would be found by the following.
9x - 6y = 20
-6y = 20 - 9x
y = -20/6 - (-9/6x)
y = 9/6x - 20/6
y = 3/2x - 10/3
To make the perpendicular line, take the slope and apply the opposite and reciprocal.
y = -2/3x - 10/3
Best of Luck!

Simplify 1,999,999 with an exponent of 0
The value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰
Before we can simplify with an exponent of zero, first we must understand that any number raised to the power of zero gives 1. Hence:
1,999,999 = 1,999,999 × 1
Since 1 can be expressed as 10⁰, the value becomes:
1,999,999 = 1,999,999 × 10⁰
Hence the value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰

Sophie went to the lake with her family. First, they spent 1 1 4 hours fishing. Then, they spent twice as much time swimming. How much time did they spend fishing and swimming in all?
Answer:
The total time spent on both fishing and swimming is 3 3/4 hours
Step-by-step explanation:
Here, we are interested in knowing the total time spent on fishing and swimming.
From the question, we are made to know that the time spent fishing is 1 1/4 hours or simply 5/4 hours.
Then they spent two times of this time swimming.
The time spent swimming is thus 5/4 * 2 = 5/2 hours
So the total time spent on both swimming and fishing will be;
5/4 hours + 5/2 hours = (5 + 10)/4 = 15/4 = 3 3/4 hours

Last year, Andrea ran about 120 kilometers during the months of March, April, and May. Estimate how many more kilometers she ran during those three months than she ran this year. Round to the nearest 1 kilometer. A 2-column table with 3 rows titled Total Distance Andrea Ran (kilometers). Column 1 has entries March, April, May. Column 2 has entries 48.7, 31.2, 35.66.
Answer:
March=49
April=31
May=36
Andrea ran about 116 km
this is about 4 km less than last year
Step-by-step explanation:
I got it right :))
Andrea ran 4 km extra last year if, and the total distance run this year is 120 km, The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.
What is subtraction?The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given:
Total distance run this year = 120 km,
The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.
Calculate the total distance = 48.7 + 31.2 + 35.66
The total distance this year = 115.56 or 116 km
Calculate the difference as shown below,
Distance = 120 - 116 = 4 km,
Thus, she ran 4 km extra last year.

Step-by-step explanation:
The covers ( there are 2) are
2* .9 mm = 1.8 mm
Depending on how they are defining pages
If they are defining pages as the number of papers
400 pages at .13 =
400 *.13 = 52 mm
total = 2 covers + 400 pages
= 1.8 + 52
53.8 mm
If they are defining pages as the page numbers
Each page number is on the front and back so 400/2 = 200 pieces of paper
200 pages at .13 =
200 *.13 = 26 mm
total = 2 covers + 400 pages
= 1.8 + 26
27.8 mm
Answer:
52.8 mm thick
Step-by-step explanation:
0.9mm X 2mm90 = 1.8 mm
0.13mm X 400mm = 52 mm
1.8mm + 52mm = 53.8 mm

-4c+25+c=3c+79
Answer:
c = -9
Step-by-step explanation:
- 4c + 25 + c = 3c + 79 Combine like terms.
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c + 3c + 25 = 3c + 3c + 79
25 = 6c + 79
25 - 79 = 6c + 79 - 79
- 54 = 6c
-54/6 = 6c/6
-54/6 = c
-9 = c
There aren't 2 answers, you could have 2 answers if one of the c's was squared. Here is another way to do the math.
- 4c + 25 + c = 3c + 79
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c - 3c + 25 = 3c - 3c + 79
- 6c + 25 = 79
- 6c + 25 - 25 = 79 - 25
- 6c = 54
- 6c/- 6 = 54/- 6
c = 54/- 6
c = - 9
Answer:
-9 = c
Step-by-step explanation:
-4c+25+c=3c+79
-3c +25 =3c+79
25 = 6c +79
-54=6c
-54/6 = c
-9 = c

Answer:
y=-2x-1
Step-by-step explanation:
first take 2 points from the graph to find m ( linear equation y=mx+b)
(-1,1) and (-2,3)
m=y2-y1/x2-x1
m=3-(1)/-2+1
m=2/-1
m=-2
now find b at point -1,1
y=-2 x+b
1=-2(-1)+b
b+2=1
b=1-2 ⇒ b=-1
y=-2 x -1
