Answer:
Step-by-step explanation:
To find the inverse of a function, you switch the x and y values and solve for y. (keep in mind that f(x) is just another way of writing y)
so is our answer
Answer:
the square is 32 but idrk about the whole thing
Step-by-step explanation:
The measures of both the angles are 163 degrees and 17 degrees
<h3><u>Solution:</u></h3>
Given that two angles are supplementary
Let one of the angle be "x"
Let the other angle be "y"
Two angles are supplementary when add up to 180 degrees
x + y = 180 ----- eqn 1
Given that One angle measures 10 more than 9 times the other
x = 10 + 9y ----- eqn 2
Substitute eqn 2 in eqn 1
10 + 9y + y = 180
10 + 10y = 180
10y = 180 - 10
10y = 170
<h3>y = 17</h3>
Substitute y = 17 in eqn 2
x = 10 + 9(17)
x = 10 + 153
<h3>x = 163</h3>
Thus the measures of both the angles are 163 degrees and 17 degrees
The first one because they go up by 4 each time thus it is linear.
Hope this helps! :)
The final price (what it is selling for) is $796.40
The markup is 10% of the original price (the dealer's cost) , meaning that it is 10% more.
We need to find the original price.
We write this as an equation
The original price *110% = final price
This is because the original price is itself (100%) added with 10%
Plug in the known final price
Original Price * 110% = 796.40
Convert 110% to a decimal because the other numbers- such as the final price are also decimal numbers.
Convert 110% to a decimal by moving the decimal point up 2 spaces ( basically dividing it by 100)
110% = 1.1
So it is now
Original price *1.1 = 796.40
Divide both sides by 1.1 to isolate our unknown, the original price
Original price = $724
