For the equation, complete the given ordered pairs. Please Help!!!
lora16 [44]

Answer:

((4,19), (\frac{-3}{4},0), (-6,-21))

Step-by-step explanation:

We have the linear equation given by, y = 4x + 3.

So, for the ordered pairs, we will substitute the given co-ordinate in the equation to find the other co-ordinate.

1. We are given, x = 4.

So, y = 4x + 3 ⇒ y = 4 × 4 + 3 ⇒ y = 16 + 3 ⇒ y = 19.

Hence, the ordered pair is (4,19).

2. It is given that y = 0.

So, y = 4x + 3 ⇒ 0 = 4x + 3 ⇒ 4x = -3 ⇒ x=\frac{-3}{4}

Thus, the ordered pair is (\frac{-3}{4},0).

3. We have, y = -21

So, y = 4x + 3 ⇒ -21 = 4x + 3 ⇒ 4x = -21-3 ⇒ 4x = -24 ⇒ x = -6.

So, the ordered pair is (-6,-21).

Hence, we get that the ordered pairs are ((4,19), (\frac{-3}{4},0), (-6,-21)).

klio [65]

Answer:

Shaheem paid $76 as his total.

Step-by-step explanation:

He paid $20 to get in, Emily paid $40 for 5 rides, and if you divide that to get the payment for one ride which is $8. So you multiply 8 by 7 because 7 is how many rides he rode which equals to 56, plus 20(his enter fee) would be $76.

Factor each equation
Ainat [17]

Answer:

x^4 - 11·x^2 + 18 = 0

I use Vieta's formulas

-9·(-2) = 18 and -9 + (-2) = -11

(x^2 - 9)·(x^2 - 2) = 0

(x + 3)·(x - 3)·(x + √2)·(x - √2) = 0

What is the solution to the system of equations 2x y 7 y 2x 3?.
Katena32 [7]

There is no solution for two equations 2x – y = 7 and y = 2x + 3 .

<h3>What is an equation?</h3>

A statement that the values of two mathematical expressions are equal (indicated by the sign =).

Name different methods to solve the system of equations .

(1)The Graphing Method .

(2)The Substitution Method .

(3)The Linear Combination Method

(4)The Addition Method

(5)The Elimination Method.

(6)The Matrix Method .

The solution of two equations

2x – y = 7 and

y = 2x + 3

On solving the two equations by Substitution Method ,we get

2x-(2x+3) =7

⇒2x-2x-3=7

⇒0 -3 =7

⇒-3 =7

But since the numbers are not equal ,so we conclude that

-3≠7

Hence ,as x gets canceled and y value is substituted ,so as a result we get two numbers which are also not equal .

Hence, there is no solution for x and y .
