x = 7 + 3y
5x + 6y = 14
Which ordered pair (x,y) is the solution to the system of equations above?

Answers

Given Equation:

x = 7 + 3y

or, x - 3y - 7 = 0 ........ (i)

5x + 6y = 14

or, 5x + 6y - 14 = 0 .........(ii)

To Find:

The value of x and y.

Solution:

By dividing eq. ii by 2, we get

5/2x + 3y - 7 = 0 ........ (iii)

By adding eq. i and eq. iii, we get

15/2x = 0

or, x = 0 ........(iv)

By putting eq.(iv) in eq. (i), we get

0 - 3y - 7 = 0

or, -3y = 7

or, y = -7/3

Answer: ( 0, -7/3 )

The value of x and y is 0 and -7/3 respectively.

(0,-7/3) is the answer please press thanks

-1/6 times -4/7 in fraction form please!! <3

Answers

This is 2/21. You can simplify the 4 in -4/7 to 2 and the 6 in -1/6 to 3. So it would now be -2/7 times -1/3. A negative times a negative is a positive, so the answer will be positive. 1 times 2 is 2 and 7 times 3 is 21. 2/21

Answer:

67/24

Step-by-step explanation:

Remember PEMDAS

First you solve the parenthesis which is 11/12.

Then do exponents 2^4=16

For division do left to right so 2/3 ÷ 16 = 1/24

and the other division is 11/12 ÷ 1/3 = 11/4

Add the two 1/24 + 11/4 = 67/24

67/24 is the answer

Step-by-step explanation:

f(x) = x² + 2x - 4

g(x) = 3x + 1

f(g(x)) = f(3x + 1)

f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4

Answers

Answer:

$22.72 for gas

Step-by-step explanation:

If each gallon costs $3.049, then we multiply the cost of each gallon by 7.45

3.049 x 7.45 = 22.71505

As the question asks us to round to the nearest cent in 22.71505, we would round up.

Your answer is $22.75 for gas
