Solve the system of linear equations by using the substitution method. Write your answer as a coordinate/point. (20 points)

Inessa [10]

Answer:

(1,10)

Step-by-step explanation:

Substitute the value of y so you get -5x+15=-2x+12. Then solve you get x=1. Substitute x as 1 in the equation y=-2x+12 so you get y=10

1. when the expression x^3+ 2kx+2 is divided by x+2, the remainder is less than the remainder when the expression is divided by

nalin [4]

Answer:

let the polynomial be

f(x)=x³+2kx+2

is divided by

g(x)=x+2

hence

(x+2) is a factor of f(x)

so comparing with x-a we get a=-2

f(a)=0

f(-2)=(-2)³+2*-2*k+2

0=-8-4K+2

4k=-6

K=-6/4

k=-3/2

again

when divided by x+1

g(x)=x+1

hence

x+1 is a factor

so a=-1

f(-1)=-(1)³+2*-1*k+2

0=-1-2k+2

0=1-2k

k=1/2

The value of k is 1/2 when divided by x+1

and

K =-3/2 when divided by x+2

Determine if the following set of ordered pairs represents a quadratic function. Explain.

Digiron [165]

Answer:

Option D

Step-by-step explanation:

Given

$(5, 7), (7, 11). (9, 14). (11, 18)$

Required

Determine if the function is quadratic

$(5, 7), (7, 11). (9, 14). (11, 18)$

Start by representing the function as an x-y table

x:- 5 || 7 || 9 || 11

y:- 7 || 11 || 14 || 18

Next; Calculate the difference between the values of y

$Difference: 11 - 7 = 4$

$Difference: 14 - 11 = 3$

$Difference: 18 - 4 = 4$

The resulting difference are: 4 || 3 || 4

Next; Calculate the difference between the difference of values of y

$Difference = 3 - 4 = -1$

$Difference = 4 - 3 = 1$

The resulting difference are: -1 || 1

For the function to be quadratic, the above difference must be the same and since they are not, then the function does not represent a quadratic function.

Option D answers the question
