if trangle pqr is translated 4 units to the right to form triangle p'q'r' how are the values on the orderd pairs affected by the

Vesna [10]

Answer:

The x-coordinate of each point will increase by 4.

Step-by-step explanation:

So Triangle PQR is being translated 4 units to the <em>right</em>. Since we are going to the <em>right</em>, this is a shift on the x-coordinate.

And since we're going 4 units, every x-coordinate is going to be added by 4.

In other words, if we have:

$A(x,y)$

Then the new coordinate, A', is:

$A(x,y)\rightarrow A' (x+4,y)$

So, let's find the new coordinates of each point.

Point P is (-5,6). So:

$P(-5,6)\rightarrow P'(-5+4,6)=P'(-1,6)$

The new Point P is at (-1,6).

Point Q is at (2,6). So:

$Q(2,6)\rightarrow Q'(2+4,6)=Q'(6,6)$

The new Point Q would be at (6,6).

And Point R is at (-3,2). So:

$R(-3,2)\rightarrow R(-3+4,2)=R(1,2)$

The new Point R is at (1,2).

And we're done!

3X squared plus 2X equals -4 number of solutions

PIT_PIT [208]

Answer:

The given equation has two solutions i.e $\frac{-1+\sqrt{13} }{3}$ , $\frac{-1-\sqrt{13} }{3}$

Step-by-step explanation:

The given expression as :

3 x² + 2 x - 4

For the quadratic equation in the form of a x² + b x + c , the value of x

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

Or, x = $\frac{-2\pm \sqrt{2^{2}-4\times 3\times (-4)}}{2\times 3}$

Or, x = $\frac{-2\pm \sqrt{4 + 48}}{6}$

or, x = $\frac{-2\pm \sqrt{52}}{6}$

∴ x = $\frac{-1\pm \sqrt{13}}{3}$

Or, x = $\frac{-1+\sqrt{13} }{3}$ , $\frac{-1-\sqrt{13} }{3}$

Hence The given equation has two solutions i.e $\frac{-1+\sqrt{13} }{3}$ , $\frac{-1-\sqrt{13} }{3}$ Answer

Janie was asked to bring water for her daughter's soccer team. The coach told her he wants each player to drink 1 8 gallon of wa

Maslowich

Answer:

1 gallon and 1 pint

Step-by-step explanation:

I guess that the actual amount of water needed per player is 1/8 of gallon and not 18 gallons.

You will need to bring 9 x 1/8 = 9/8 = 1 ¹/₈ gallons or 1 gallon and 1 pint

1 gallon = 4 quarts = 8 pints = 16 cups = 128 ounces

1 gallon = 3.785 liters

The US is one of the few countries (along with Liberia, and Myanmar) that still uses the imperial system to measure things, e.g. inches, feet, yards, pounds, miles, pints, gallons, etc. The rest of the world uses the metric system, e.g. meters, liters, kilograms, etc.
