What is equivalent to 3x – 2y = 4?
Answer:
This equation is equal to y=3/2x-2
Step-by-step explanation:
5y= 1/2x -10 find slope and y intercept.
Answer:
Slope = 1/10
Y intercept = -2
Step-by-step explanation:
5y = 1/2x - 10
Divide both sides by 5
5y/5 = 1/2x - 10 /5
You will get y = 1/0x - 2
The x part is the slope and the whole number on the far right is the y intercept.
So the slope is 1/10
The y intercept = -2
The sum of two consecutive even integers is 48 less than 3 times the largest integer. Find both integers algebraically.
Answer:
44 and 46Step-by-step explanation:
Let the integers be:
n and n + 2Then we have:
n + n + 2 = 3(n + 2) - 48Solving for n:
2n + 2 = 3n + 6 - 483n - 2n = 2 + 48 - 6n = 44So the numbers are 44 and 46
Which expression represents the sum of 31 and 104,
divided by 3?
Answer:
The answer is 45Step-by-step explanation:
Well all you really need to do is add 31 and 104 which is 135 then divide it by 3 and well you got the answer 45
The expression (31 + 104) / 3 is equal to 45.
The expression that represents the sum of 31 and 104, divided by 3, can be written as (31 + 104) / 3.
To calculate the value, we start by evaluating the sum of 31 and 104, which gives us 135. So, the expression becomes 135 / 3.
Dividing 135 by 3 yields a result of 45.
Therefore, (31 + 104) / 3 is equal to 45.
The expression simplifies the process of finding the sum of the two numbers (31 and 104) by first adding them together and then dividing the sum by 3. This calculation provides a concise representation of the desired arithmetic operation and its solution.

Order of Operations: BPEMDASAlg I
Equality PropertiesStep-by-step explanation:
Step 1: Define inequality
-2x + 1 < 7
Step 2: Solve for x
Subtract 1 on both sides: -2x < 6Divide both sides by -2: x > -3Here we see that any value greater than -3 would work as a solution of x.
Answer:
x>-3
Step-by-step explanation:
First, isolate the variable. So, move the 1 onto the other side.
Because signs change when moved to the other side, + becomes - .
Then, subtracte. 7-1=6.
DIvide both sides by -2.
-2x/-2 is x, and 6/-2 is -3.
So, x>-3

There are 7 girls and 13 boys in a class at a Private
School. Of these students, 5 girls and 3 boys are in
the Running club. What percentage of the students
at this Private School are in the Running club?
Answer:
40%
Step-by-step explanation:
Number of girls = 7
Number of boys = 13
Total students = 7 girls + 13 boys
= 20 students
Running club
Number of girls = 5
Number of boys = 3
Total students in the running club = 5 girls + 3 boys
= 8 students
percentage of the students that are in the Running club = Total students in the running club / Total students
× 100
= 8/20 × 100
= 0.4 × 100
= 40%
Percentage of the students
at this Private School are in the Running club is 40%

To evaluate f(- 2), substitute x = - 2 into f(x), that is
f(- 2) = 2(- 2) + 6 = - 4 + 6 = 2
