x>4/-4
x>-1
x<-1
Answer:
Yes, 1:3.
Step-by-step explanation:
Each of the numbers on figure 2 are 3 times the number on figure 1.
Simplify 1/3(6x - 15) to 6x - 15/3
6x - 15/3 = 1/2(10x - 4)
Factor out the common term; 3
3(2x - 5)/3 = 1/2(10x - 4)
Cancel out 3
2x - 5 = 1/2(10x - 4)
Simplify 1/2(10x - 4) to 10x - 4/2
2x - 5 = 10x - 4/2
Factor out the common term; 2
2x - 5 = 2(5x - 2)/2
Cancel out 2
2x - 5 = 5x - 2
Subtract 2x from both sides
-5 = 5x - 2 - 2x
Simplify 5x - 2 - 2x to 3x - 2
-5 = 3x - 2
Add 2 to both sides
-5 + 2 = 3x
Simplify -5 + 2 to -3
-3 = 3x
Divide both sides by 3
- 1 = x
Switch sides
<u>x = -1</u>
Answer:
43/10
Decimal Form: 4.3
Step-by-step explanation:
First, you have to find<span> the axis of symmetry and vertex. Next, make a function to model a linear relationship between the two quantities. Finally, find the rate of change and </span>initial value<span> of the function from a description of a relationship or from 2 (x , y) </span>values<span>, including reading these from graph or a table.</span>
