what is the linear inequality?!?!?!
Answer:
y ≥ 2x + 1
Step-by-step explanation:
you want to find the slope, then the y-intercept, and set the equation in slope intercept form, but imma give you a tip so you know when its either y ≥ x or
y ≤ x, so when its y ≥ x, the shaded part will be to the left of the graph, or the top of the graph if y ≥ any number, but for y ≤ x or any number, it will be on the right side of the graph or the bottom if its a horizontal line that includes anything less then the y-intercept, but for a normal function, you can plug in values to figure out if its ≥ or ≤
Answer:
linear inequality is a numerical statements which involves the following signs
i. <
ii. >
iii.≥
iv.≤

Equation parallel to y = 3x + 2 and passing through (1, 1)
Answer:
y = 3x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, then
y = 3x + c ← is the partial equation
To find c substitute (1, 1) into the partial equation
1 = 3 + c ⇒ c = 1 - 3 = - 2
y = 3x - 2 ← equation of line
What is an equation of the line that passes through the points (2, 2) and (-2, 8)?
Answer:
y = −1.5x + 5
Step-by-step explanation:
x y
2 2
-2 8
From 2 to 8, we need to add 6 ( y section)
From 2 to -2, we need to subtract 4 (x section)
Now we need to do y/x
so...y/x = -6/4 = -3/2 = - 1.5
And thats how we find our slope.
To find the y-intercept I just used a graph in order to find it.....

2.) there are 8 dictionaries and 25 reference books all together including the dictionaries so you would add 8+5+12 in order to get 25...
3.) There are 16 green and 6 red and you divide both by 2 and get 8 to 3
4.) there are 6 red and 24 blue you can divide both by 6 in order to get 1 to 4
5.)there are 24 blue and 46 in all but they can both be divide by 2 in oreder to get 12 to 23

A school band raised $252 by holding a car wash. The band
washed 42 cars in all. Which equation can be used to find n,
the average amount they earned per car?
The equation that can be used to find the average amount they earned per car is 42n = 252 and they earned $6 per car.
Given that a school band raised $252 by holding a car wash, they washed 42 cars in all.
We need to determine the equation that can be used to find n, the average amount they earned per car.
To find the average amount earned per car (n), you can use the equation:
n = Total amount raised / Total number of cars washed
In this case, the total amount raised is $252, and the total number of cars washed is 42.
So the equation to find n would be:
42n = 252
n = 252 / 42
Now, you can calculate n:
n = 6
Therefore, the average amount they earned per car is $6.

Nora is a teacher and takes home 31 papers to grade over the weekend. She can grade at a rate of 6 papers per hour. How many papers would Nora have remaining to grade after working for 5 hours? ( show work )
Answer:
Nora would have 30 papers graded in 5 hours.
Step-by-step explanation:
6 papers per hour x 5 hours = 30 papers graded in 5 hours
Answer:
Nora will have 1 page left to grade after working for 5 hours.
Step-by-step explanation:
Her constant is 6 papers per hour.
After 5 hours, she would grade 5x6 papers, which is 30 papers.
So we know she is going to grade 31 papers, and she has already done 30.
So 31-30=1, that means that she has 1 more paper left to grade.
