Answer:
y = 5/2x + 1/2
Step-by-step explanation:
Find the slope with the formula [ y2-y1/x2-x1 ].
-2-3/1-(-1)
-5/2
undefined
Find the y-intercept using the formula for slope-intercept form [ y = mx + b ]
y = -5/2x + b
3 = -5/2(-1) + b
3 = 5/2 + b
1/2 = b
Put everything we solved for into its final form.
y = 5/2x + 1/2
Best of Luck!
Answer:
y = -2.5x + 0.5
Step-by-step explanation:
First we must find the slope.
To do so we will use this formula:
y2 - y1 / x2 - x1
Substitute with (-1, 3) and (1, -2)
-2 - 3 / 1 + 1
-5/2
-2.5 is our slope.
Now to put this into slope-intercept form we will use Point-slope formula.
y - y1 = m(x - x1)
substitute using the ordered pair, (-1, 3):
y - 3 = -2.5(x + 1)
Distribute:
y - 3 = -2.5x + -2.5
Add 3 to both sides:
y = -2.5 + 0.5
Double check by using the other ordered pair.
(1, -2)
y + 2 = -2.5(x - 1)
Distribute:
y + 2 = -2.5x - 2.5
Add 2 to both sides:
y = -2.5x + 0.5
(-1, 3) and (1, -2) written in slope intercept form is:
y = -2.5x + 0.5
Write the sentence as an equation.

Step-by-step explanation:
Look at the two equations: -3x + 6 = 21 -3x + 6 < 21 Which statement best describes the process used to solve the equations? In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality. In both cases, divide by –3 on both sides, but reverse the inequality sign when doing that for the inequality. The process is exactly the same for solving the equation and solving the inequality. The process for solving the equation is entirely different from solving the inequality.
Answer:
b

Step-by-step explanation:
You already have $75. The monitor costs a total of $400. You save $25 each week. Write an equation using w, to represent the number of weeks that you will have to save in order to purchase the monitor. Use your equation and solve algebraically. Explain your solution.
Answer:
13 weeks
Step-by-step explanation:
25w + 75 = 400
25w = 400 - 75
25w = 325
25w/25 = 325/25
w = 13
It will take 13 weeks until you can buy the monitor
Answer:
So if there is 13 weeks you re able to buy the monitor but if it's less than 13 weeks you are broke.(lol)
Step-by-step explanation:
already have $75
monitor costs a total of $400.
each week 25
400 -75 =325
325 divided by 25 =13

if 30 houses cost 1.7 billion, how much money will 300 houses cost?
Answer:
17 billion cause 30*10 300
Answer:
If 30 houses cost 1.7 billion, 300 houses cost 17 billion
Step-by-step explanation:
If you were to make it an equation you would make it
30 = 1.7
Now we were told the 30 would be made 300 so its obvious you multiplied by 10 and whatever you did to one side you do to the other so its
30 x 10 = 1.7 x 10 is 300 = 17
your answer is 17 billion

Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher?
Answer:
There is 2.215 liters in each of the 4 pitchers.
Step-by-step explanation:
Let x be the number of liters in each of the 4 pitchers.
4x + 0.5 = 9
4x = 8.5
x = 2.125

The table represents some points on the graph of a linear equation.What is the rate of change of y with respect to x for this function?
Answer:
Step-by-step explanation:
what we know=
x is the independent variable and y is the dependent variable.
our co-ordinates can be expressed in the form of (x value, y value).
so... we only need two points for this so let's just list two points so it goes faster
A(-7,5)
B(-1,65)
alright, now we have two points. we're trying to find the rate of change, which in other words, is the slope.
m=(y-y1)/(x-x1) <-- plug in our points.
m=(65-5)/(-1-(-7)
m=60/(-1+7)
m=60/6
m=10
therefore the rate of change aka the slope of this table of values is 10.

Cindy did an experiment. She started out with 600 bacteria cells. She found that the growth rate of the bacteria cells was 4.1%. Create an equation for the situation that would work for any time, x.
Pls Help thx
Answer:
Step-by-step explanation:
Hello! Im doing the same problem for my midterm and I believe the answer would be 0.041x+600.
Since x represents the time, x can be anything. 0.041 would equal the percentage of 4.1% and you need the growth rate times the time to equal your answer. +600 would be what she started out with, which is the bacteria cells. Hope this answers your question!!!
