Find an equation for the line below.
Help me please :(
Answers
Answer:
y=3/2x+5/2
Step-by-step explanation:
I used the Y2-Y1/X2-X1
In this equation you can see that there are 2 points (-5,-5) and (1,4)
If you substitute, you will get
4+5/1+5
9/6 and if you simplify this, you will get 3/2
Now that we have the slope, we just have to use y=mx+b
(I'm using the point (1,4)) 4=3/2(1)+b
4=3/2+b
5/2=b

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each, and the laptops cost $439.00 each. If the math department has $6,500 to spend and purchases 30 textbooks, how many laptops can they buy
Answers
Answer:
6 laptops
Step-by-step explanation:
First, find the amount spent on the textbooks:
30(116)
= 3480
Subtract this from the total amount they have to spend:
6500 - 3480
= 3020
Divide this amount by 439 to find how many laptops they can buy:
3020/439
= 6.8
Round down to 6 since you can only have full laptops:
= 6
So, they can buy 6 laptops

The ratio of the coefficient is the same so it will be the infinite solution of a given system of the equation so option (C) will be correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A linear equation could contain more than one variable. When the maximum power of the variable is constantly uni, an equation is said to be linear.
Given the set of equation
4x - 2y = 12
20x - 10y = 160
The ratio of x coefficient = 4/20 = 1/5
The ratio of y coefficient = -2/-10 = 1/5
The ratio of the constant term = 12/160 = 1/5
Since all ratios are the same so there will be an infinite number of solutions.
The question was incomplete, but the complete question is given below.

of X+4. He tells his teacher the answer is 3x-1. Is he correct or incorrect and why?
Answers
Answer:
No
Step-by-step explanation:
No, because the perimeter of a rectangle is 2(x+y). Justin added the sides. Then he should have multiplied by 2 but he didn't so Justin is incorrect.
Hope this helps plz mark brainliest :D
Answer:
No, his answer should have been 6x+2

HELP PLS
Answers
Answer:
y=2/3x-7
Step-by-step explanation:
The slope intercept formula is
y=mx+b
(m) is the slope (rate of change)
(b) is the y intercept (where the line crosses the y axis [vertical])
We need to find the slope and the y intercept. First we will find the slope.
The formula for slope is y1-y2/x1-x2
In and ordered pair the first value is the (x) and the second is the (y).
(x, y)
We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.
5-(-1)/8-4
Simplify.
5-(-1) =5+1= 6
8-4=4
6/4 Simplify
3/2 is our slope.
Now we apply out new slope into our y=mx+b
y=3/2x+b
Now we need to find the (b) which is the y intercept.
To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).
In this ordered pair 4 is the (x) and -1 is the (y)
So replace (y) with -1 and (x) with 4
-1=3/2(4)+b
Now solve as usual.
-1=6+b
subtract 6 from each side
-7=b
b=-7
Put our (m) and (b) into our formula.
y=2/3x-7 is our equation.

Inequality form x less than or equal to -13
Step-by-step explanation
Answer:
x ≤ -13
Step-by-step explanation:
2(x + 1) - 3(x + 5) ≥ 0
Distribute the 2
(2 × x) + (2 × 1)
2x + 2 - 3(x + 5) ≥ 0
Distribute the -3
(-3 × x) + (-3 × 5)
2x + 2 - 3x + (-15) ≥ 0
2x + 2 - 3x - 15 ≥ 0
Combine like terms
2x - 3x + 2 - 15 ≥ 0
-x + (-13) ≥ 0
-x - 13 ≥ 0
+13 +13
-x ≥ 13
Divide both sides by -1 and flip the sign
x ≤ -13

Each bowling ball weighs 7.3*10^3 grams. The bowling alley has 2.0*10^2 bowling balls. How much do they all weigh, combined? Express your answer in scientific notation.
Answers
Answer:
1.46 x 10⁶g
Step-by-step explanation:
Given parameters:
Weight of each bowling ball = 7.3 x 10³g
Number of balls in the bowling alley = 2.0 x 10²bowling balls
Unknown
The weight of the balls in the alley = ?
Solution:
To find the weight of the balls in the alley, multiply the mass of each balls with the total number of balls;
Weight of the balls = 7.3 x 10³ x 2.0 x 10²
Weight of the balls = (7.3 x 2.0) x 10³⁺²
Weight of the balls = 14.6 x 10⁵g
Therefore, the weight of the balls = 1.46 x 10⁶g
