Answer:
Step-by-step explanation:
1) Least common denominator of 4 and 2 is 4
To eliminate the fraction, each term should be multiplied by 4
ANS:option c
2) Mercury level of water 'y' years = Initial measure +rate of increase 'y' years
0.05 +0.1y = 0.12+0.06y
Ans : Option c
3) 4b +6 = 2 - b + 4
Add 'b' to both sides
4b + b + 6 = 2 + 4
5b + 6 = 6
Subtract 6 from both sides
5b = 6 - 6
5b = 0
b = 0
Ans : Option b
4) Maximum decimal places in this equation is 2. So, to eliminate decimal places, The equation should be multiplied by 100
Ans: option d
5) y +6 = -3y + 26
Add 3y to both the sides
y + 6 + 3y = 26
y + 3y + 6 = 26
4y + 6 = 26
Subtract 6 from both sides
4y = 26-6
4y = 20
Divide bothe sides by 4
y = 20/4
y = 5
Ans: option c
6) '2x' is subtracted from both side of the equation.
Ans: option a - subtraction property of equality
X is -2 I think if you’re solving for x if not 3^4 is 81
13. No
14. No
15. Yes; Domain: (-4,3) Range: (-4)
The domain values uniquely map to the dependent variable.
A function that fits these values is f(x)=20x+1020.
You have a 42% chance of catching today.
There are 2 situations in which you are going to catch.
Mr. Smith is the coach and he says yes. The probability of this happening is: 0.6 x 0.5 = 0.3
Mr. Jones is the coach and he says yes. The probability of this happening is: 0.4 x 0.3 = 0.12
If you add the probabilities together, you get 0.42 or 42%.
