Answer:

$x = - 1$

Step-by-step explanation:

$- 5x + 11 = - 8(6x + 4)$

$= > - 5x + 11 = - 48x - 32$

Lets keep the variable terms in L.H.S. and the constant terms in R.H.S.

$= > 48x - 5x = - 32 - 11$

$= > 43x = - 43$

Lets divide 43 on both the sides.

$= > \frac{43x}{43} = \frac{ - 43}{43}$

$= > x = - 1$

The perimeter of parallelogram ABCD is 46 inches. What is DA?

nadezda [96]

First we have 8x -5=3x+10, so x =3.
Hence AB =CD =19.
So 38+DA +BC =46, but DA =BC,
38+2DA=46, then 2DA =8,
DA =4.

Annette [7]

Using the relation between velocity, distance and time, it is found that the commute took 48 minutes.

<h3>What is the relation between velocity, distance and time?</h3>

Velocity is distance divided by time, that is:

$v = \frac{d}{t}$

For Lena, we have that d = 29, v = 36, hence the time in hours is given by:

$t = \frac{d}{v} = \frac{29}{36} = 0.8056$

In minutes, the time is given by:

tM = 0.8056 x 60 = 48.

For what value of k is there one solution to the given quadratic equation (k+1)x²+4kx+2=0.

andriy [413]

Answer:

If $k = 1$ or $k = -\frac{1}{2}$ , there is only one solution to the given quadratic equation.

Step-by-step explanation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = (x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

$\bigtriangleup = b^{2} - 4ac$

The signal of $\bigtriangleup$ determines how many real roots an equation has:

$\bigtriangleup > 0$ : Two real and different solutions

$\bigtriangleup = 0$ : One real solution

$\bigtriangleup < 0$ : No real solutions

In this problem, we have the following second order polynomial:

$(k+1)x^{2} + 4kx + 2 = 0$ .

This means that $a = k+1; b = 4k; c = 2$

It has one solution if

$\bigtriangleup = 0$

$b^{2} - 4ac = 0$

$16k^{2} -8(k+1) = 0$

$16k^{2} - 8k - 8 = 0$

We can simplify by 8

$2k^{2} - k - 1 = 0$

The solution is:

$k = 1$ or $k = -\frac{1}{2}$

So, if $k = 1$ or $k = -\frac{1}{2}$ , there is only one solution to the given quadratic equation.

Allison, Brianna, and Celeste went on a hike. Allison brought 9 homemade

poizon [28]

Answer:

Allison = $0.27

Brianna = $1.89

Step-by-step explanation:

The total cookies that the three girls have are:

Allison's cookies + Brianna's Cookies

= 9+15

=24

There is a total of 24 cookies which has to be divided between the 3.

Each girl gets 24/3 = 8 cookies.

Since Celeste had no cookies she will have to pay for the 8 cookies.

Allison had 9, she will give one to Celeste

Brianna had 15 out of which she will use 8 for her self and 7 will be given to Celeste.

Celeste is paying 2.16 for 8 cookies.

Price of one cookie = 2.16/8

=$0.27

So, amount that will be given to Allison = 0.27 * 1 = $0.27

Amount that will be given to Brianna = 0.27 * 7 = $1.89
