A rental car company charges 69.60 per day to rent a car and 0.15 for every mile driven khloe wants to rent a car knowing that she plans to drive 325 miles she has at most 380 to spend
Answer:
118.35
Step-by-step explanation:
Equation: 69.60 + 0.15x (x being miles)
New equation: 69.60 + 0.15(325)
= $118.35
example: Use substitution to PLEASE find the solution
system & y = 2x - 35
6x + 3y = 15
Answer:
put value of y in equation
6x + 3(2x-35) = 15
6x + 6x - 105= 15
12x = 15+105
x = 120/12
x = 10
now put value of x in first equation to find y
y = 2(10) -35
y = -15

what is a linear equation
Answer:
A linear equation is an algebraic equation of the form y=mx+b. Where m is the slope and b is the y-intercept. A linear equation most times is called a "linear equation of two variables," where y and x are the variables.

Answer:
x²-4x+7
-x²-6x-12
Step-by-step explanation:
1.) the first thing we do is expand the exponent (or mulitply (x-2)(x-2) the images below will show you how to do that
We get x²-4x+4 and then just need to add three
x²-4x+7
2.)
We do the same thing (expand the exponent) and get x²+6x+9
which means so far we have
-(x²+6x+9)-3
carry out the negative sign and subtract 3
-x²-6x-12

EXPLAIN when |−x| = x would be true.
HINT: If you are stuck, try substituting each of x = -1, x = 0, and x = 1 into the equation. Then, interpret your results.
Answer:
It's true when x = a positive number.
Step-by-step explanation:
I don't know how to explain this, so here we go.
The definition of absolute value is the distance a number is away from 0.
In other words, all numbers are now positive or 0.
If |-x| = x, it means x would have to be positive because, well, to prove that, we have to see what it couldn't be a negative number
if x was a negative number (-1), this is what we would get
|-(-1)| = -1
|1| = -1
1 = -1
That's not right!
And this happens in any negative number you do.
Because the absolute value of something cannot be negative
I cannot stress that enough
Since it is the absolute value of -x, x has to be positive, if it isn't, then there is no solution for x.
Any number greater than or equal to zero is a possible answer for the absolute value of something, but the absolute value of something cannot be a negative number
I hope this helps, let me know if you have any questions.

What is X for brainliest
Answer:
the value of x is 2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
Given 3 parallel lines intersected by 2 transversals then the parallel lines divide the transversals proportionally, that is
[tex]\frac{3x}{4}[/tex] = [tex]\frac{7.5}{2.5x}[/tex] ( cross- multiply )
7.5x² = 30 ( divide both sides by 7.5 )
x² = 4 ( take the square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2
A line intersects the points (-8, -1) and
(1,8). What is the slope-intercept
equation for this line?
HELP
Answer:
m=1
Step-by-step explanation:
Answer:
y = -x + 7
Step-by-step explanation:
slope between (-8, -1) and (1, 8) is 9/9 or 1
y = mx + b
8 = 1(1) + b
b + 1 = 8
b = 7
y = -1x + 7

Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week. Elena starts with $10 in her savings account and adds $20 each week.
Answer:
6 weeks
Step-by-step explanation:
You need to write an equation for each.
For Andre, he has 100 dollars, and every week gets 5 dollars more. You add the 5 dollars, and Since you don't know how many weeks it has been, use a variable.
For Elena, she has 10 dollars, and gets 20 each week.
Now that you know that it has been 4 weeks, you can plug in 4 for the variable for weeks.
Andrew:100+5(4)=100+20+120
Elena: 10+20(4)=10+80=90
Andrew has more money in this time.
To find when they have the same amount, equal their expressions to each other. This means that they will have the same amount (because they are equalled) and you can solve to find the variable, which means the weeks that they are equal at.
Bring the like terms to each side by canceling them out. Since you have positive 10, then subtract 10 to each side. You have 5w, so subtract 5w to each side.
100+5w=10+20w
90+5w=20w
90=15w
90 divided by 15=6
w=6
Help please!! Inverse trigonometry
Answer: x = 40.5
============================================================
Work Shown:
Let h be the height of the largest triangle of this diagram. This is the vertical segment of unknown length.
Focus on the smaller triangle on the left side.
Side h is an adjacent side with 25 as the hypotenuse. We can tie the two together with the cosine ratio
cos(angle) = adjacent/hypotenuse
cos(52) = h/25
25*cos(52) = h
h = 25*cos(52)
h = 15.3915368831414
h = 15.4
The height is roughly 15.4 units
---------------------------
Now we use the tangent rule to find the value of x
Focus on the smaller triangle
tan(angle) = opposite/adjacent
tan(x) = h/18
tan(x) = 15.4/18
tan(x) = 0.85555555555556
x = arctan(0.85555555555556)
x = 40.5488259971136
x = 40.5
This value is approximate and it's not as accurate compared to using more decimal digits in h; however, the instructions say that you should "round to the nearest tenth at each step".
Side note: make sure your calculator is in degree mode.
