Answer:
The number is -100, Jill can think of something else, now.
Step-by-step explanation:
x = the number
x/4 - 20 = -45 {twenty less than one-fourth of the number is -45}
x/4 = -25 {added 20 to each side}
x = -100 {multiplied each side by 4}
Answer:
I can't graph on this but x > -6
To graph you should draw a vertical (up and down) dotted line, and shade the graph to the right of the line.
Step-by-step explanation:
2x+3>-9 Subtract 3 from both sides of the inequality.
2x> -12 Divide both sides by 2
x> -6


Using hit and trial, you van find it pretty easily-
- Putting x=0, we get y=-3
- Putting x=1, we get y=-1
- Putting x=2, we get y=5
You can try it for yourself as well, for me, I couldn't find any other option appropriate.
The value of the number 2.4x10⁻⁴ in the standard notation is 0.00024.
<h3>What are Scientific notations?</h3>
The way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5×10¹².
As the value of the scientific notation is given 2.4x10⁻⁴, therefore, for bringing it in the standard form we need to shift the decimal to the left by four digits. So,

Hence, the value of the number 2.4x10⁻⁴ in the standard notation is 0.00024.

Answer:
7
Step-by-step explanation:
Working backwards:
19 + 9 = 28
28/ 4 = 7
Checking work:
7 x 4 = 28
28 - 9 = 19
