P = (5,-2)

R = (-5,1)

Q= (4,-5)

Step-by-step explanation:

First of all, find the line of symmetry, so the opposite side of the original shape. Next, if one of the corners (for example R) is one square away from the line of symmetry, you will have to put the corner on square away from the line on the other side. You must repeat this, join the dots, and you are done. Hope it helps

Kisachek [45]

Answer:

Ryan isn't correct.

Step-by-step explanation:

If Ryan wants to make exactly 3 cups of dip, he would need 3/8 pounds of chicken.

1/8(3)=3/8 pounds.

3/4, or 6/8 pounds of chicken doesn't represent 3 cups, it's for 6 cups of dip.

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.

Answer:

3 3/4 teaspoons

Step-by-step explanation:

Pedro mixes 3/4 teaspoon of plant food into each gallon of water. How many teaspoons of plant food should Pedro mix into 5 gallons of water? To answer this, multiply "3/4 teaspoon per gallon" by 5 gallons:

3 teaspoons

------------------- * 5 gallons = 15/4 teaspoons, or 3 3/4 teaspoons.
