Answer:
Company A makes more for one purchase, and Company B makes more for ten purchases. Company C makes less for one purchase and Company A makes less for ten purchases.
Step-by-step explanation:
Company A: y = -3/5x + 65
Company B: y=1/2x + 62
Company C: 11/25x + 57
Make sure x is 1 then do all the equations, then x is 10 and do all the equations to see which has more amount of money and which has less.
Company A: 64.4 (if x = 1)
Company B: 62.5 (if x = 1)
Company C: 57.44 (if x = 1)
<em>if x = 10</em>
Company A: 59
Company B: 67
Company C: 61.4
(I might be wrong since I'm 14)
Company A makes more for one purchase, and Company B makes more for ten purchases. Company C makes less for one purchase and Company A makes less for ten purchases.
Correct answer is D.
Use equation of line which passes through the point
![A(x_1,y_1)](https://tex.z-dn.net/?f=A%28x_1%2Cy_1%29)
.
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Answer:
(3rd listed choice) Paula's notes are incorrect. Step 4a should be "If the result does not define y as a function of x, then f does not have an inverse," and step 4b should be "If the result defines y as a function of x, then f has an inverse."
Step-by-step explanation:
If f(y) = x can be solved for a relation for y that is a function, then f(x) has an inverse. It will be the function defined by y.
Okay so I was taught that you take the zeros off each number:
90 x 80 -> 9 x 8
then you just multiply those numbers:
9 x 8 = 72
and then add both the zeros onto the sum:
72 + 00 = 7200
and theres your answer
Step by step explanation
Irrational numbers are any real numbers that are not rational. So 0 is not an irrational number. Some (in fact most) irrational numbers are not algebraic, that is they are not the roots of polynomials with integer coefficients. These numbers are called transcendental numbers.
