Answer:
x=1
Step-by-step explanation:
5(5x+4)=45
25x+20=45
subtract 20 on each side
25x=25
divide by 25 on each side
x=1
Answer:
1 to 5
211 to 1500
11 to 300
Step-by-step explanation:
1.8 to 9 = 18/90 = 1(18)/5(18) = 1/5 = 1 to 5
2.11 to 15 = 211/1500 = 211 to 1500
3.30 to 90 = 330/9000 = 110/3000 = 11/300 = 11 to 300
There will be 2 bacterias after 20 minutes
Answer:
Option B, -10000
Step-by-step explanation:
<u>Step 1: Find the number that would be valid</u>
As the x value gets closer to -1, the y values go to positive and negative infinity. Therefore, the best value out of the options given would be -10,000 since it is the closest to negative infinity.
Answer: Option B, -10000
Y = x^2 + 6 doesn’t not belong in the group.
When graphing an x squared it will appear as an parabola (an U shaped graph).
As you can see the rest of the linear equation uses y=mx + b, except for the 3rd one.
