Answer:

Step-by-step explanation:

The parent graph (red) is y = x^2

To get that graph to move right 4 units, the graph become y1 = (x - 4)^2

To get the graph to move up 1 unit, add 1 on the right. y2 = (x -4)^ + 1

The answer is D

Note: getting a graph to move left or right is a bit anti-intuitive. If you want it to move right, you have to subtract a number from x before before squaring the result. Your intuition would tell you to add the number, but that moves the graph left.

Answer:

$\frac{13\pi }{9}$ radians

Step-by-step explanation:

to convert degrees to radians

degrees × $\frac{\pi }{180}$

= 260 × $\frac{\pi }{180}$

= 26 × $\frac{\pi }{18}$

= 13 × $\frac{\pi }{9}$

= $\frac{13\pi }{9}$

Find the domain of y=2/3x-1 if the range is {-3, -1, 7, 17}.

White raven [17]

<h3>Answer: The domain is {-3, 0, 12, 27}</h3>

=========================================

Explanation:

First solve for x to get

y = (2/3)x - 1

y+1 = (2/3)x

(2/3)x = y+1

x = (3/2)*(y+1)

-------

Now plug the values given into y. Do so one at a time. Lets plug in y = -3

x = (3/2)*(y+1)

x = (3/2)*(-3+1)

x = 1.5*(-2)

x = -3

So the domain value x = -3 corresponds to the range value y = -3.

-------

Repeat for y = -1

x = (3/2)*(y+1)

x = (3/2)*(-1+1)

x = 1.5*0

x = 0

The domain value x = 0 corresponds to the range value y = -1

-------

Repeat for y = 7

x = (3/2)*(y+1)

x = (3/2)*(7+1)

x = 1.5*8

x = 12

The domain value x = 12 corresponds to the range value y = 7

-------

Repeat for y = 17

x = (3/2)*(y+1)

x = (3/2)*(17+1)

x = 1.5*18

x = 27

The domain value x = 27 corresponds to the range value y = 17

You and your friend collect each rocks and fossils. your friend collects three times as many rocks and half as many fossils as y

Murljashka [212]

Answer:

you - 4 rocks and 16 fossils
friend - 12 rocks and 8 fossils

Step-by-step explanation:

Let the rock be r and the fossil be f

<u>Equations</u>

You: r + f = 20
Friend: 3r + 1/2f = 20

<u>Double the second equation and subtract the first one:</u>

2(3r + 1/2f) - (r - f) = 2*20 - 20
6r - r = 20
5r = 20
r = 4

f = 20 - 4 = 16

So you collect 4 rocks and 16 fossils

<u>Friend collects:</u>

4*3 = 12 rocks and
1/2*16 = 8 fossils
