Solve 5x-y=5 and 2y-x^2=11 without using trial improvement

iren2701 [21]

Answer:

x = 7, y = 30 and x = 3, y = 10

Step-by-step explanation:

5x - y = 5, then y = 5x - 5

2y - x^2 = 11

2(5x - 5) - x^2 = 11

10x - 10 - x^2 = 11

-x^2 + 10x -10 = 11

-x^2 + 10x -21 = 0

x^2 - 10x + 21 = 0

(x - 7)(x - 3) = 0

x = 7, y = 30

x = 3, y = 10

bob has 64 cups. could he distribute them into 6 equally in stacks and not have any left over? Explain

Iteru [2.4K]

Bob cannot distribute the cups in six equal stacks and not have any left over.

Step-by-step explanation:

In order to divide the total number of cups in six equal stacks with no left over, the total number of cups will be divided by 6, if there is any remainder then the cups cannot be equally divided with no left over.

Dividing 64 by 6

$= \frac{64}{6} \\= 10\frac{4}{6}$

Here

Quotient = 10

Remainder = 4

As there are 4 cups left, Bob cannot distribute the cups in six equal stacks and not have any left over.

Explain what is happening at this step in the solving equation process.

aleksklad [387]

Answer:

1. After solving we get value of x: $\mathbf{x=\frac{6}{11} }$

2. After solving we get value of x: $\mathbf{x=\frac{6}{11} }$

Step-by-step explanation:

We need to Solve the equations.

1. $10 - 6 x = 4 + 5 x$

Step 1: Subtract 5x on both sides

$10 - 6 x-5x = 4 + 5 x-5x\\10-11x=4$

Step 2: Subtract 10 on both sides

$10-11x-10=4-10\\-11x=-6$

Step 3: Divide both sides by -11

$\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}$

So, after solving we get value of x: $\mathbf{x=\frac{6}{11} }$

2. $7-6x=1+5x$

Step 1: Subtract 5x on both sides

$7 - 6 x-5x = 1 + 5 x-5x\\7-11x=1$

Step 2: Subtract 7 on both sides

$7-11x-7=1-7\\-11x=-6$

Step 3: Divide both sides by -11

$\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}$

So, after solving we get value of x: $\mathbf{x=\frac{6}{11} }$
