Fed [463]3 years ago
5 0

Answer:

x= 4.2

Step-by-step explanation:

2/3x^2=23-15

2/3x^2=8

Sq. root both sides

2/3x = 2.8

multiply both sides by 3

2x= 8.4

divide both sides by 2

x= 4.2

A line has a slope of and a y-intercept of –2.<br><br> What is the x-intercept of the line?
irakobra [83]

Answer:The equation of the line that has a slope of -1/2 and a y-intercept of -2 is: y=-1/2x-2. All you really have to do here is replace m with -1/2, which is the slope you gave, and replace b with -2, the y-intercept you gave, in the equation y=mx+b. 

If this helped, please mark me brainliest, thank you and if you need more help, feel free to message me .

Can someone pls pls help me?
vova2212 [387]

Answer:

i think 88

Step-by-step explanation:

(it's been a while since I've done this so I'm not too sure it's correct)

The formula we need to use is

2πr(angle/360)

we need the radius (r)

To get r we need angle AES

180-80= 100

using the equation from before

88=2πr*(100/360)

raidus: 50.42

Then to get the length CD we need angle DEC

180-80=100

2π*50.42*(100/360)=88

there probably was some kind of shortcut we could've used to figure this out faster but whatever
