Mathematics
1 answer:
Artemon [7]3 years ago
4 0

Answer:

8/81

Step-by-step explanation:

It's most efficient to simplify the quotient algebraically before inserting the values of the variables x and y.  

The given expression reduces to x³ / y^4.

Substituting 2 for x and 3 for y, we get:

 (2)³           8

--------- = ---------- (Agrees with first given possible answer)

 (3)^4         81

Simplify and solve for the unknown. Use order of operations as needed.<br>8×2+5^2-y=2(y+1)+6 ​
Ket [755]

Answer:

y = 11

Step-by-step explanation:

8 × 2 + 5²- y = 2(y + 1) + 6 ​

8 × 2 + 5²- y = 2y + 2 + 6 ​

8 × 2 + 25 - y = 2y + 2 + 6 ​

16 + 25 - y = 2y + 2 + 6

41 - y = 2y + 8

41 (- y + y) = (2y + y) + 8

41 = 3y + 8

41 - 8 = 3y (+ 8 - 8)

33 = 3y

33/3 = 3y/3

y = 11

Answer:

Greatest Common Factor: integer or variable multiplied by other integers or variables that creat a resultin product. factor x factor = product

difference of squares binomial: an expression where two perfect square terms are being subtracteda² - b² = (a+b)(a-b)quadratic: from "quad" meaning square, because the variable gets squared (like x2).

discriminant: tells you about the roots of a quadratic

general form: y = a(x - h)^2 + kstandard form: ax^2 + bx + c = 0root: a solution of an equation

zero: a value that gives you 0 for a function

x-intercept: where the graph crosses the x-axis

y-intercept: where the graph crosses the y-axis

extraneous: a solution that does not work

parabola: the graph of a quadratic

vertex: the turning point of the parabola

axis: line of reflection

translation: movement up/down and left/right of any parabola from standard position (f(x) = x2)

The basics of what you should know

(1 point) Deshaun is a plumber who charges $40 per hour for his work. Another plumber, Silvio, charges based on the equation d =
SashulF [63]

Answer:

A

Step-by-step explanation:

Deshaun charges $40 per hour.

So if Deshaun and Silvio work for 5 hours, then it would be $40(5) which would be more expensive than Silvio's with $60 + 20(5). Silvio gets $60 with $20 per hour.

Deshaun would get $200 while Silvio would get $160.
