How do I graph an inequality in one variable?

1 answer:

7 0

It depends on the variable.

If it's something like x < 2, your graph would be a vertical line at x = 2, and everything to left of that line shaded in (because of the less than).

Similarly for y, except it would be a horizontal line with either everything above or below shaded.

You can have other equations like 0<x<4 where everything between x = 0 and x = 4 would be shaded

73. If 65% of x is 130, what is the value of x? A. 84.5 B. 130 C. 165 D. 200 E. 260

MrRissso [65]

Answer:

D) 200

Step-by-step explanation:

To find what x equals you have to use the expression:

is over of equals percent over 100

In this problem you are given the percent, 65%, and the is, 130.

So we are trying to find the of so you would substitute of with x.

So 130/x = 65/100

Now you would do Cross Product Property to find x.

So 130*100 = 13000

65*x = 65x

65x = 13000

65/65 = 1

13000/65 = 200

x = 200

So 65% of 200 is 130

C(squared)L(squared) + 100v(squared) = 100c(squared) I have to solve for L

jeyben [28]

First subtract 100v² from both sides to get:

C²L²=100c²-100v²

Then divide both sides by C²:

L²=(100c²-100v²)/C²

Then take the square root of both sides:

L=+ or - the square root of (100c²-100v²)/C²

What is the range and domain of (-3,-22) (-2,-8) (-1,2) (0,8)) (1,10) (2,8) (3,2)

BartSMP [9]

Answer:

Step-by-step explanation:

domain is x component so

domain = {-3 , -2 , -1 , 0 , 1 , 2 , 3 }

range is y component so

range = { -22 , -8 , 2 , 8 , 10 , 2 }

note : repeated element can be written only one time. For eg here in range 8 is 2 times but we can write only one time because it is the rule for lisying range and domain.
