Answer:
1250
Step-by-step explanation:
?/5000 = 25/100 5,000x25= 125,000 divided by 100= 1250.00= 1250
Answer:
a) 
b) The inverse function is a reflection of the original function across the line
y = x. For example, if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x. So you would use it to find the x-value at a y just like you use the original to find the y value at an x.
Step-by-step explanation:
To do an inverse of a function you first switch the independent variable (d) and the dependent variable (c).
d = 0.45c + 5.50
Then you solve for c
d - 5.50 = 0.45 c
c = (d-5.50)/0.45
Answer:
A. 7 burritos for $51.50
Step-by-step explanation:
22.50/3=7.50
1 burrito cost $7.50
2 burritos will cost $15.00
2×7.50=15
5 burritos will cost $37.50
5×7.50=37.50
4 burritos will cost $30.00
4×7.50=30.00
However, 7 burritos will not cost $51.50 because 7×7.50=52.50 not 51.50
I assume you are being asked to solve these equations. Since there wasn't an explanation as to how you are expected to solve them, I chose to demonstrate how to use a calculator matrix function. You can find matrix calculators online. My instructions are for a TI-84
Push the blue 2nd button then push x^-1 button (it says matrix above this button in blue)
Arrow over to edit to change the dimensions of the matrix and to put in your values. You have 3 equations (3 rows) and 4 terms (4 columns) so you put a 3x4 in for the dimension and the coefficients (see images).
You use the rref option in the math column in matrix to calculate the answer.
The numbers at the end are the solutions. x = -4, y = 2, z = -1
