Answer:

Patel can use the first and last steps.

Step-by-step explanation:

The given equation is :

8x^{2} +16x+3=0

Patel can use the last step.

8(x^{2} +2x)+3=0

Taking 3 to right hand side, we get

8(x^{2} +2x)=-3

He can also use this step.....

8(x^{2} +2x+1)=-3+8

Upon solving we get,

8x^{2} +16x+8=-3+8

=> 8x^{2} +16x=-3+8-8

=> 8x^{2} +16x=-3

Show a way to count from 668 to 900 using ones tens and hundreds
cricket20 [7]
Hey there!

You can count from 668 to 900 using the following:

668 → 768 → 868 (two 100s)

868 → 878 → 888 → 898 (three 10s)

898 → 899 → 900 (two 1s)

Hope this helped you out! :-)

Solve for x.
Masteriza [31]

Answer:

x = 2.5 or -0.8

Step-by-step explanation:

Here, we are to use completing the square method to solve for the values of x

Firstly, we divide through by 4

= x^2 -7/4x -2 = 0

Now, we move the two term to the right hand side

x^2 -7/4x = 2

Now, we divide the coefficient of x by 2 and square it;

That would be;

(-7/4 * 1/2)^2 = 49/64

we now add this value to both sides of the equation

x^2 -7/4x + 49/64 = 2 + 49/64

The right hand side can be rewritten as;

(x-7/8)^2 = 177/64

taking the square root of both sides

x-7/8 = √(177/64)

x = 7/8 ± √(177/64)

x = 7/8 + √(177/74) or 7/8 - √(177/64)

= x = 2.53802 or -0.788017

Which to the nearest tenth is

x = 2.5 or -0.8

PLISS ANSWER :C DONT ANSWER IF YDK THAnKSSS<br> *also pls look at both images :)*
Iteru [2.4K]

Answer:

First image: (6, -1)

2nd image: y = 63

Explanation:

1)

2x + y = 11

1/2x - 5y = 8

y = -2x + 11

1/2x - 5(-2x + 11) = 8

1/2x + 10x - 55 = 8

10.5x - 55 = 8

10.5x = 63

x = 6

2x + y = 11

2(6) + y = 11

12 + y = 11

y = -1

(x , y) = (6, -1)

2)

1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5

2y - 1.2 = 1.8y + 10.8 + 0.6

0.2y - 1.2 = 11.4

0.2y = 12.6

y = 63
