Answer:
y=-1x-2
Step-by-step explanation:
hope it helps ^^
Answer:
y = -x - 2
Step-by-step explanation:
Since we have a straight, linear line, the line follows the y = mx + b format
The line moves one unit down for every unit to the right, making m = 1
Since the line has a downward slope, m = -1
Since the line crosses the y-axis at -2, b = -2
Therefore, the equation is y = -1x - 2 or more simplified, y = -x - 2

what does Brittney need to do to make the order correct?
Answers
She needs to convert all the numbers be be the same type ( fraction or decimal).
With the numbers she has it would be easiest to convert all the numbers to decimals.
72/80 = 0.9
3 1/5 = 3.3
Pi = 3.14
Now she can arrange the decimals in order:
-2.9, 0.9, 2.979, 3.14, 3.2
She needs to switch 3 1/5 and pi

The number of fish in a lake decreased by 25% between last year and this year. This year there are 45 fish in the lake. What was the population of last year
Answers
Answer:
The population of last year was 60.
Step-by-step explanation:
From the information given, as you know that the number of fish in a lake decreased by 25% between last year and this year, the amount of fish this year represents 75% of last year's population as: 100%-25%=75%. With that, you can use a rule of three to find last year's population tha would represent 100% given that 75% is equal to 45 fish.
75% → 45
100% → x
x=(100*45)/75= 60
According to this, the answer is that the population of last year was 60.

€400 is divided between Ann, Brian and Carol so that Ann has twice as much as Brian and Brian has three times as much as Carol. How much does Brian receives ?
Answers
Answer:
€120
Step-by-step explanation:
Let us represent
Ann = x
Brian = y
Carol = z
€400 is divided between Ann, Brian and Carol
Hence: x + y + z = €400...... Equation 1
Ann has twice as much as Brian
Hence:
x = 2y
Brian has three times as much as Carol.
y = 3z
z = y/3
We substitute
x + y + z = €400...... Equation 1
2y + y + y/3= €400
Multiply both sides by 3
2y × 3 + y × 3 + y/3 × 3 = €400 × 3
6y + 3y + y = €1200
10y = €1200
y = €1200/10
y = €120
How much does Brian receives ?
Since, Brian = y
Brian receives €120

Each term in the second factor is multiplied by each term in the first factor, that is
n²(2n + 3) - 3n(2n + 3) + 1(2n + 3) ← distribute the parenthesis

Brent spends $ 420 on his monthly bills. Of this amount, 15 % is for utilities, 1/5 is for Internet service, and 1/7 is for phone service. If the rest of the total amount is for food, how much money does Brent have for food?
Answers
Answer: $213
Step-by-step explanation:
First find out how much is spent on the other things:
Utilities
= 15% * 420
= $63
Internet services
= 1/5 * 420
= $84
Phone service
= 1/7 * 420
= $60
The amount left for food is therefore:
= 420 - money spent on other things
= 420 - 63 - 84 - 60
= $213

Find the reflection of the following point over the y-axis: (7, -3)
Answers
Answer:
(-7,-3)
Step-by-step explanation:
You keep the -3 since that is the y but the x will become negative because you are reflecting to the left and not the right, making the x then negative.
Answer: (-7,-3)
Step-by-step explanation:
The point (7,-3) is located in the fourth quadrant mean that if you reflect the point across the y a-xis, it should end up in the third quadrant.
If you flip a point over the y axis, the x coordinate switches.
(7,-3) ⇒ (-7,-3)
It took Ciera 24 minutes to drive 18 miles. It took chains of one hour to drive 46 miles. Who is driving at a faster rate?
Answers
Answer:
Ciera is driving at a faster rate.
Step-by-step explanation:
You calculate speed, by dividing distance by time.
So 18 divided by 24 is 0.75. That is Ciera's speed.
And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667
Therefore, Ciera is driving faster.
A light-year is the distance light travels in one year, about 5.9×1012 mi. Earth is located about 25,000 light-years from the Milky Way's rim. What is the approximate distance, in miles, from Earth to the rim of the Milky Way?
Answers
Answer:
1.475 × 10¹⁴ mi
Step-by-step explanation:
Since 1 light year = 5.9 × 10⁹ mi and the Earth is located about 25,000 light-years from the Milky Way's rim, the approximate distance, in miles, from Earth to the rim of the Milky Way is 25,000 light year = 25,000 × 1 light year
= 25,000 × 5.9 × 10⁹ mi
= 147.5 × 10¹² mi
= 1.475 × 10¹⁴ mi

y = x - 4 y = -0.5x + 8
a. (4,2)
b. (8,4)
c. (4,8)
d. (2,4)
Answers
Answer:
x = 8, y = 4
Step-by-step explanation:
y = x - 4
y = -0.5x + 8
y = y
x - 4 = -0.5x + 8
x + 0.5x = 8 + 4
1.5x = 12
x = 12/1.5
x = 8
To get "y" substitute the 8 for the "x" value in any of the two equations (they will both give the same answer.)
y = (8) - 4
y = 4
OR
y = -0.5(8) + 8
y = -4 + 8
y = 4
