Answer:
y=2x+5
Step-by-step explanation:
−8x+4y=20
Step 1: Add 8x to both sides.
−8x+4y+8x=20+8x
4y=8x+20
Step 2: Divide both sides by 4.
4y4=8x+204
y=2x+5
B)decreases by one; arrow length decreases by 1/3
Answer:
x^3 +8x^2 +13
Step-by-step explanation:
(6x^2 - 3 + 5x^3) - (4x^3 - 2x^2 - 16)
Distribute the minus sign
6x^2 - 3 + 5x^3 -4x^3 + 2x^2 + 16
Combine like terms
x^3 +8x^2 +13
Answer:
w=[-14.1667, ∞)
Step-by-step explanation:
the variable w can be any real number less than the value of 85, thus -6 multiplied by any number greater than the value of 14.1667 shall be less than 85. the value for the minimum limit number is obtained dividing 85 by -6 due to the varibale -6w and the value 85 as the maximum limit.
![\boxed{ \textbf{ \huge{Answer: A}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Ctextbf%7B%20%5Chuge%7BAnswer%3A%20A%7D%7D%7D%20)
A linear function has 1 as the highest power of the variable.
A. f(x) = 2 - 7x
here, the highest power of the variable x is 1.
Hence it is a LINEAR function.
___________
B. f(x) = 2 + x + x^2
here, the highest power of the variable x is 2.
Hence it is NOT a linear function.
_______________
![c.f(x) = \sqrt{2 + 7x}](https://tex.z-dn.net/?f=c.f%28x%29%20%3D%20%5Csqrt%7B2%20%2B%207x%7D%20)
here, the highest power of the variable x is 1/2.
Hence it is NOT a linear function.
