A linear equation exists for the following sets of ordered pairs: {(-1, 1), (0, 3), (-1/3, 7/3)}. The rule for the linear equati
kaheart [24]

Answer:

Part 1) y=2x+3

Part 2) The equation satisfy the set of coordinates (see the explanation)

Step-by-step explanation:

step 1

Find the linear equation

The rule for the linear equation states that y is three more than twice x.

so

The variable y is equal to the number 2 multiplied by x plus the number 3

y=2x+3

step 2

Prove that the equation satisfies the set of coordinates

substitute the value of x and the value of y in the linear equation and then compare the results

a) (-1, 1)

1=2(-1)+3

1=1 ----> is true

so

The equation satisfy the ordered pair

b) (0, 3)

3=2(0)+3

3=3 ----> is true

so

The equation satisfy the ordered pair

c) (-1/3,7/3)

7/3=2(-1/3)+3

7/3=7/3 ----> is true

so

The equation satisfy the ordered pair

therefore

The equation satisfy the set of coordinates

Which expression is a factor of 21x2 + 13x – 20?A. 3x – 4B. 7x - 5C. 7x + 4D. 3x + 5
LUCKY_DIMON [66]

Answer:

B. 7x - 5

Explanation

Given the expression 21x^2 + 13x – 20, to get which of the given expression is a factor we will have to factorize the equation first as shown;

21x^2 + 13x – 20

= 21x^2 + 28x - 15x - 20

= 7x(3x+4) -5(3x+4)

= (7x-5)(3x+4)

Hence one of the factors is 7x - 5

20+26+26 = 72

to get the mean of four numbers  means

(x+x+x+x) / 4 = 25

so

100-72=28
