You just add each number by itself each time.
4+4=8
8+8=16
16+16=32
32+32=64
64+64=128
128+128=256

D, the number inside of the absolute lines are just the exact same number in there but just positive. If the number was positive the number would still be the number:

|100| = 100
|-100| = 100

What is an equation of the line that passes through the point (-1, 4) and is parallel
vesna_86 [32]

Answer:

The answer is

<h2>y + 2x = 2</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is 2x + y = 1

We must first write the equation in the general form above

That's

y = - 2x + 1

Comparing with the general equation above

Slope = - 2

Since the lines are parallel their slope are also the same

Slope of parallel line = - 2

So the equation of the line using point

( - 1 , 4) and slope - 2 is

<h3>y - 4 =  - 2(x + 1) \\ y - 4 =  - 2x - 2 \\ y + 2x =  - 2 + 4</h3>

We have the final answer as

<h3>y + 2x = 2</h3>

Hope this helps you

11) x-intercept: 12
y-intercept: 8

12) x-intercept: -18
y-intercept:-16

13) x-intercept: 6
y-intercept:10

Sorry I can't graph it for you but here are the equations in the slope-intercept form

11)y=-2/3x+8
12)y=-8/9x-16
13)y=-5/3x+10

Please answer :) it seems like something that should be easy but I totally forgot how to do it!
Gwar [14]
It's essentially asking for the value of y on the graph of function f(x) when x is equal to -4.

Graphically, we can see that when x = -4, y would be 1.

If you had to do this algebraically with an equation for the function, just slot the value of -4 in for x, to find the value for y.

23) The area of one piece of pizza is 14.13 in? If the pizza is cut into eighths, find the radius of
ira [324]

Answer:

2.12in

Step-by-step explanation:

Pizza is circular in nature

Area of a circle = πr²

r is the radius

Given

A = 14.13in²

14.12 = 3.14r²

r² = 14.12/3.14

r²= 4.49

r = 2,12in

Hence the radius of the pizza is 2.12in
