Answer:
14
Step-by-step explanation:
f(x)=3x²+1
f(2) = 3 x 2² + 1 = 13
g(x) =1-x
g(2) = 1 - 2 = -1
(f-g)(2) f(2) - g(2) = 13 - (-1) = 14
Answer:
X is negative 5/ -5
Step-by-step explanation:
90 round to the nearest hundredth
Set up a system of equations.
d + q = 75
.1d + .25q = 14.25
Multiply the first equation by -.1 so that the "d's" will cancel.
-.1d -.1q = -7.5
.1d +.25q = 14.25
Now add the two equations together
.15q = 6.75
divide both sides by .15
q = 45
There are 45 quarters in the jar

Explanation: Find 19% of 30 to find answer
2. B- Between 40-60 minutes
Explanation: Measure the difference between the intervals
3. B is correct.
Explanation: From the graph the actual heart rate=150=150
but calculated heart rate from best fit line=148=148
Difference between actual and calculated=150-148=2=150−148=2
