Answer:
Step-by-step explanation:
g(-1) = 4(-1) - 3 = -4 -3 = -7
f(-7) = (-7)^2 + 3 = 49 + 3 = 52
Answer is D
Answer:
6. 8b²-5b-4
7. -3x²+9x-4
8. 3
9. 6a+15
Step-by-step explanation:
you will subtract/add the numbers with the same variables and exponent.
ex. (number 6) 7b²+ b²= 8b²
5b= 5b 8b²+5b-4
1-5= -4
(plus 5b because it didnt come out to a negative) if you have any questions, say in the comments and ill try my best to help
Answer:
Step-by-step explanation:
Answer:
1: 6
2: 1,2,3
3: 4m-1>5m-4
4: Not enough data
5: n = 11
6: The ceiling is lower than 3m
7: G = 7
8: C = 18
9: p + 18 = 41; p = 23
10: D = 100t
Step-by-step explanation:
Question 1:
5*2+x/2-7
5*2+6/2-7
10+6/2-7
10+3-7
13-7
6
Question 2:
4*2<16
8<16 True
4*1<16
4<16 True
4*3<16
12<16 True
4*4<16
16<16 False
Question 3:
Let's plug in 1 for m
4*1-1____5*1-4
4-1_____5-4
3_____1
3>1
Question 4:
You did not give an equation, so I cannot answer.
Question 5:
2*11 + 5 =27
22 + 5 = 27
27 = 27
So n = 11
Question 6:
x<3
The ceiling is lower than 3m because x<3
Question 7:
5.1g = 35.7
5.1g/5.1=35.7/5.1
g = 7
Check: 5.1 * 7 = 35.7
Question 8:
36 + c = 54
36 + c -36 = 54 - 36
c = 18
Check: 36 + 18 = 54
Question 9:
p + 18 = 41; p = 23 is correct because the number of paperback books plus the number of hardcover books would equal the total number of books sold. Check: 23 + 18 = 41
Question 10:
d=100t is correct because each time t goes up one it goes up 100. Example: if it is at one hour, than it is 100, if it is at 3 hours, than d = 100*3 = 300, which is the same pattern as the table.
Hope this helps!
