Please help and explain with these 2 math questions!!!!!!

Volgvan

1) -10x+y=4

Now, you should substitute x in every situation.

* x=-2 => -10*(-2)+y=4... 20+y=4... y=-16

* x=-1 =>-10*(-1)+y=4... 10+y=4... y=-6

*x=0 => -10*0+y=4... y=4

* x=1 => -10*1+y=4... -10+y=4... y=14

* x=2 => -10*2+y=4... -20+y=4... y=24

2) -5x-1=y

For example: x=0

-5*0-1=-1

The function f ( x ) = x ^3 + 2x^2− 5 x − 6 has a root at 2. Name all roots of this function.

Tomtit [17]

sub x=1 into f(x),

remainder= 1^3+2(1)^2-5(1)-6= -8

since remainder≠0, x=1 is not a root of the function

sub x=-1,

remainder = (-1)^3+2(-1)^2-5(-1)-6= 0

by remainder theorem,

x=-1 is a root of f(x)

hence, the correct ans is c

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (4, 6)

Point (-2, -2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute [DF]: $\displaystyle d = \sqrt{(-2-4)^2+(-2-6)^2}$
Subtract: $\displaystyle d = \sqrt{(-6)^2+(-8)^2}$
Exponents: $\displaystyle d = \sqrt{36+64}$
Add: $\displaystyle d = \sqrt{100}$
Evaluate: $\displaystyle d = 10$
