what is the variable in the expression 3y+8
Answer:
y
Step-by-step explanation:
Variables are letters or symbols in an equation that represent a value we do not know.
In this equation, there is a y. y is not a number, but a letter, meaning this is the value we do not know, or the variable.
Answer:
y
Step-by-step explanation:
It is y because 8 will be constant and 3 will be a term I think and i know for y is variable

t-shirts for $2 and shorts for $4. the total sales were $600. they sold four times more tshirts than shorts how many tshirts and shorts did they sell?
Answer:
T-shirts: 200
Shorts: 50
Step-by-step explanation:
To solve, set up an equation using two variables to represent the number of t-shirts and shorts sold. Let x = t-shirts sold. Let y = shorts sold. 2x + 4y = 600. We know that x will be 4 times greater than y, so we can plug in some guesses that seem reasonable and use the equation to test our theories. My first guess was 50 shorts, which by luck was the correct answer. These problems can be tricky, but setting up an equation can prove to be a great help.
What is the y-intercept of the line given by the equation y = 8x + 75?
A. (0,75)
B. (0,-8)
C. (0, -75)
D. (0,8)
Answer:
The answer is A.
Step-by-step explanation:
In a linear equation, y = mx + b where b represent y-intercept.
y-intercept is the point where it touches y-axis, so the value of x is 0.
The y-intercept of the given equation is (0, 75). Therefore, option A is the correct answer.
What is a y-intercept?In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
The given equation of a line is y=8x+75.
To find the y-intercept, set x = 0 and solve for y.
Here, substitute x=0 in y=8x+75, we get
y=8(0)+75
y=75
So, the y-intercept is (0, 75)
Therefore, option A is the correct answer.

Which equation in point-slope form describes the line that passes through the point (4,-5) and is perpendicular to
the line represented by - 7x + 2y = 14?
Answer:
y = -2/7x - 27/7
Step-by-step explanation:
first find the slope of the line -7x + 2y = 14 by solving for 'y'
2y = 7x + 14
y = 7/2x + 7
since the slope is 7/2 then the line that is perpendicular will need the opposite and reciprocal of 7/2 which is -2/7
knowing the slope ('m') and having the point (4, -5) we can find the y-intercept of the new line ('b')
y = mx + b
-5 = (-2/7)(4) + b
-5 = -8/7 + b
[change -5 into -35/7]
-35/7 + 8/7 = b
b = -27/7
put 'm' and 'b' into y = mx + b
y = -2/7x - 27/7

Marcus daims that in the expression 3x + 3y, the terms 3x and 3y are like terms because both are variable terms and both have the same coefficient. Is Marcus correct? Explain
Answer:
Step-by-step explanation:
3x and 3y are not "like terms," despite having the same coefficient.
Like terms have the same variable. For example, 3x and 2x are like terms, so
3x+2x = 5x

Leah read 1/2 of a book in the morning, and she read some at night. By the end of the day, she still had 2/5 of The book to read left. How much of the book did Leah read at night?
Answer:
1/10
Step-by-step explanation:
First, you have to get common denominators, so we will use 10. She read 5/10 in the morning, so that is 5/10 of the book left. 2/5 = 4/10 left, so if you added those two numbers up, you only get 9/10. So this means that she read 1/10 at night. I hope this helps!
