HS: Algebra 2A [M] (Prescriptive) (GP)/ 5 Quadratic Functions
ipn [44]

Answer:

Linear, the linear term is -21x and the constant term is -20. Last option is the answer

Step-by-step explanation:

We are given the following function:

y = (x - 5)(5x + 4) - 5x^2

First we have to simplify y, before solving the question:

y = (x - 5)(5x + 4) - 5x

Applying the distributive property:

y = 5x^2 + 4x - 25x - 20 - 5x^2

y = 0x^2 - 21x - 20

y = -21x - 20

No quadratic term, so it is linear.

The linear term is -21x and the constant term is -20.

PLZ help with 6th math homework!
vitfil [10]
I'm not doing your math homework, this is to help you learn and pass your test :) I will however show you a trick. ask your self this... "What can i factor out of 4x that i can also factor out of 8, which this would be 4. Now what you do if you divide everything by 4

4x/4 = x
8/4 = 2

so 4(x+2) is 4x+8 fully factored, NOW to check, use the distributive property, Multiply 4 back into x+2
4*x = 4x
4*2 = 8
so 4(x+2) = 4x+8

Find the circumference of the following circle. Use 3.14 for π. Round to the nearest hundredth
LuckyWell [14K]

Formula for the circumference of a circle:

C = 2πr     (C = circumference      π(pi) = 3.14.....    r = radius)

You know:

r = 9 cm      

π = 3.14       So substitute/plug it into the equation

C = 2πr

C = 2(3.14)(9)

C = 56.52 cm
