<span>(3a^2 - 2a + 4) - (a^2 - 3a + 7) = (distribute the negative sign)
3a^2 - 2a +4 - a^2 + 3a - 7 = (add like terms)
2a^2 + a - 3
So, the answer is A!

1. B put 4 into the g(x) equation the result is your x for the f(x) equation
2. C reverse of what is stated above
Answer:
1. Median = 10.1
2. A. The median represents the center.
3. D. The mode(s) can't represent the center because it (they) is(are) not a data value.
Step-by-step explanation:
Mean of a sample = sum of the samples/no of the samples
Samples in increasing order:
9.8
9.8
9.9
10.1
10.4
10.6
11.1
Mode is the sample with highest frequency.
Median is the middle entry of the data.
Mean = (9.8 + 9.8 + 9.9 + 10.1 + 10.4 + 10.6 + 11.1)/7
= 717/7
= 10.243
Median = 10.1
Mode = 9.8 because it has the highest frequency of 2
Answer:
-61.83
Step-by-step explanation:
Given expression is 
We know that 0.6 is 3 times 0.2 so we can cancel 0.6
Also 8.5-2.5 = 6
⇒
⇒
= -61.83
6p+4/6=4p-8/3 The goal is to always isolate the variable which in this case is p
First bring 4p to the left by subtracting (opposite operation) 4p from both sides. We are left with 2p+4/6=-8/3. We will continue isolating the variable by bring 4/6 to the right by subtracting it from both sides.
We are left with 2p=-10/3
Then divide (opposite operation) both sides by 2 to get p=-5/3
