Using the quadratic formula to solve 11x2 – 4x = 1, what are the values of x? StartFraction 2 Over 11 EndFraction plus-or-minus

slamgirl [31]

Answer:

$x=\frac{2}{11}\pm\frac{\sqrt{15}} {11}$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$11x^{2} -4x=1$

equate to zero

$11x^{2} -4x-1=0$

$a=11\\b=-4\\c=-1$

substitute in the formula

$x=\frac{-(-4)\pm\sqrt{-4^{2}-4(11)(-1)}} {2(11)}$

$x=\frac{4\pm\sqrt{60}} {22}$

$x=\frac{4\pm2\sqrt{15}} {22}$

$x=\frac{2\pm\sqrt{15}} {11}$

$x=\frac{2}{11}\pm\frac{\sqrt{15}} {11}$

therefore

Mrs. Kong uses 1 over 3 of a stick of butter in a sauce she then uses 5 over 8 of the butter to make garlic bread what fraction

Allisa [31]

Answer=1/24

1/3+5/8=
to solve for this, we need the denominators of the fractions to match.

The LCM of 3 and 8 is 24

1/3=8/24
5/8=15/24

8/24+15/24=23/24

Now if we're using 23/24, then only 1/24 is left.

24/24-23/24=1/24

Ivan and Adeline are in a classroom with a chalkboard. They are standing on different halves of the board, and on each half, the

solong [7]

Answer:

The number of times Ivan and Adeline have the same number written on the board is 6.

Step-by-step explanation:

Consider the procedure as follows:

On each half of the board, the number 2 is written.
On Ivan's teacher's signal, Ivan multiplies the number on his side of the board by -2 and writes the answer on the board, erasing the number he started with.
Adeline does the same on each signal, except that she multiplies by 2.
The teacher gives 10 signals in total.

Consider the numbers on each half of the board:

Ivan Adeline

2 2

2 × -2 = -4 2 × 2 = 4

-4 × -2 = 8 4 × 2 = 8

8 × -2 = -16 8 × 2 = 16

-16 × -2 = 32 16 × 2 = 32

32 × -2 = -64 32 × 2 = 64

-64 × -2 = 128 64 × 2 = 128

128 × -2 = -256 128 × 2 = 256

-256 × -2 = 512 256 × 2 = 512

512 × -2 = -1024 512 × 2 = 1024

-1024 × -2 = 2048 1024 × 2 = 2048

Thus, the number of times Ivan and Adeline have the same number written on the board is 6.
