Answer:
75
Step-by-step explanation:
You will set the equation up as part/whole = percent/100 and when you replace it with your numbers you get 60/x = 80/100 now you cross multiply and do 60*100 = 80 * x and you get 6,000 = 80x now you divide both sides by 80 then you get 75 was the original price
Identify the best first step in solving the linear equation: x+12=10
add 12 to both sides of the equation
convert the equation to 12x=10
divide both sides of the equation by 12
subtract 12 from both sides of the equation
The graph of y = e^x is transformed as shown in the graph below. Which equation represents the transformed function?
Answer:
it's b. y= [tex]y= e^{b}+3[/tex] on edg2020
Transformed functions are functions that are modified by some transformation. In this question the transformation of y=[tex]e^x[/tex] that is y = [tex]e^x[/tex]+ 3.
Transformation function:Assume we have a function y = f(x). Further tinkering with that function transforms it.The given graph is 3 units higher than the graph of y = [tex]e^x[/tex] Since the vertical axis reflects the outputs of functions, whatever y = [tex]e^x[/tex], there are 3 units added to the outputs.As a result, we have the transformed function of y = [tex]e^x[/tex], which corresponds to the graph y = [tex]e^x[/tex] + 3.Therefore, the transformation of the given function y= [tex]e^x[/tex] that is "y = [tex]e^x[/tex] + 3".

Let Fran - f and Nancy - n
The ages at present:
f = 3nIn four years:
f + 4 = 2(n + 4)Simplify and substitute f:
f + 4 = 2n + 8f = 2n + 43n = 2n + 4n = 4Find f:

A rental car agency charges $16 per day plus 14 cents per mile to rent a certain car. Another agency charges $23 per day plus 10 cents per mile to rent the same car. How many miles per day will have to be driven for the cost of a car from the first agency to equal the cost of a car from the second agency?
a) 175 miles per day
b) 1750 miles per day
c) 97.5 miles per day
d) 975 miles per day
Answer:
Step-by-step explanation:
The answer is 175 miles per day. I guessed on it and it was right :D
The number of miles per day that will have to be driven for the total cost of of a car from the first agency to equal the total cost of a car from the second agency is 175.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A rental car agency charges $16 per day plus 14 cents per mile to rent a certain car. Therefore, we can write,
Total charge for x miles = $16 + $0.14(x)
Another agency charges $23 per day plus 10 cents per mile to rent the same car. Therefore, we can write,
Total charge for x miles = $23 + $0.10(x)
Since it is needed to be found the number of miles that the car should be traveling so that the total cost from both the agencies is the same. Thus, equate the equation together,
$16 + $0.14(x) = $23 + $0.10(x)
16 + 0.14x = 23 + 0.10x
0.14x - 0.10x = 23 - 16
0.04x = 7
x = 7 / 0.04
x = 175 miles per day
Hence, the number of miles per day that will have to be driven for the total cost of of a car from the first agency to equal the total cost of a car from the second agency is 175.

X = 6y + 7
x = 10y + 2
Step by step plz
Answer:
(14.5, 1.25)
Step-by-step explanation:
Since they are both equal to x you have to set them equal to each other.
so 6y + 7 = 10y + 2 then solve
-6y -6y
7 = 4y + 2
- 2 - 2
5 = 4y
/4 /4
y = 1.25 (1 1/4)
Now you have to substitute y in.
x = 6y + 7
x = 6(1.25) +7
x = 7.5 + 7
x = 14.5

Step-by-step explanation:
So the angles in a quadraleteral add to 360
so put this in as an equation
4x-10 +x+62 + 2x+ 68 +3x +10= 360
10x+130=360
10x = 230
x=23
then work out each angle to find the smallest
x +62 = 85
2x+68 = 114
3x+10 = 79
4x-10 = 82
