PLS HELPPPPP Which expression is equivalent to 4−a−a−a?
Answer: " 4 − 3a " .
________
Step-by-step explanation:
" 4 − a − a − a " ;
= 4 − 1a − 1a − 1a " ;
= ? " ;
________
Combine the "like terms" :
________
→ " − 1a − 1a − 1a " ;
= (− 1a − 1a) − 1a ;
= ( − 2a) − 1a ;
= − 3a ;
________
Now, bring down the "4" ;
and rewrite the expression:
________
→ " 4 − 3a " ;
which cannot be simplified further.
________
The answer is: " 4 − 3a " .

Zachary purchased a new car for $29,995. The value of the car linearly depreciated to $9,300 over 10 years. Write a linear equation to represent the value y of Zachary's car (in dollars) after x years since its purchase.
Answer:
Step-by-step explanation:
y=-1,869.5x+27,995
Step-by-step explanation:
Let
x-----> the time in years
y----> value of Zachary’s car in dollars
A(0,27,995), B(10,9,300)
step 1
Calculate the slope
The formula to calculate the slope between two points is equal to
m=\frac{y2-y1}{x2-x1}
substitute
m=\frac{9,300-27,995}{10-0}=-1,869.50
step 2
Find the equation of the line
The equation of the line into slope intercept form is equal to
y=mx+b
we have
m=-1,869.50
b=27,995 -----> the y-intercept is the point A
substitute
y=-1,869.5x+27,995
hope this helps have a good day

5x-6y-3a
Hey there!
5x - 6y - 3a
= 5(-2) - 6(3) - 3(-4)
= -10 - 18 - 12
= -28 - (-12)
= -28 + 12
= -16
Therefore, your answer is: -16

Hey, guys, I did help. So I'm making my own video game for a science project and I need help coming up with my own video game. What should my video game be like? Make it simple. Also please don't report me because I'm doing this for a science project.
Who is the video game for? If its for gamers, make it something that a gamer would like. If its for people who need help with studies, make it educational. It all depends on the audience ;)

1) The equation 2y + 3x = 12 in the y = mx + b form is [tex]y = -\frac{2}{3} x + 4[/tex]
2) The linear equation y = -2x - 1 in the Ax + By = C form is 2x + y = -1
The point-slope form of the equation of a line is y = mx + b
where m represents the slope
b represents the y-intercept
The given equation is:
2x + 3y = 12 (Given)
Subtract 2x from both sides
2x + (-2x) + 3y = 12 + (-2x)
3y = 12 - 2x (Equality property of addition)
3y = -2x + 12 (Commutative property of addition)
Divide both sides by 3
[tex]\frac{3y}{3} = -\frac{2}{3} x + \frac{12}{3} \\\\y = -\frac{2}{3} x + 4[/tex](Equality property of division)
2) Write the linear y = -2x - 1 into Ax + By = C
y = -2x - 1 (Given)
Add 2x to both sides
y + 2x = -2x + 2x - 1 (Equality property of addition)
y + 2x = -1
2x + y = -1 (Commutative property of addition)

A proportional relationship goes through the point (4, 10). Explain how to write a function in the form y = mx for this relationship.
Answer:
m = 5 / 2
Step-by-step explanation:
Given
(4, 10)
Here,
x=4 and y=10
Given equation,
y=mx _ equation 1
putting the value of x and y in equation 1. we get,
y = mx
or, 10 = m4
or, 10 / 4 = m
or, 5 / 2 = m
therefore, m = 5 / 2
