Red line shows
y=x^2-4 , cause it's going through point (0,-4)
So blue line shows
y= -x^2+1 Point (1,0) belong to it , moreover x factor is negative , so the arms of parabola will go down
Have nice evenig :)

Alright, for 10, let's see 2(x+3). Use the distributive property to multiply 2 with x, which is 2x. Then, multiply 2 with 3, which is 6. Add them together to get 2x+6. For the second part, 4 times x is 4x and 4 times negative 2 is -8. Add them all up and you get 2x+6+4x-8=6x-2. Remember that you can't add a variable with other variables/just numbers, and a minus sign in front of terms in parenthesis means that everything in the parenthesis is negative!
Answer:
11. 135 mph
12. 40 Oz
13. 50 m
14. 2500
15. 240
i don't know 16
Step-by-step explanation:
11. 27 x 5= 135 mph
12. 24 : 6 x 10= 40 Oz
13. 1.5 : 3 x 100= 50 m
14. 40% = 1000
10% = 250 (1000 : 4 = 250)
100%= 2500 (250 x 10 = 2500)
15. 75% -> 25% = : 3
180 : 3 = 60
180 + 60 = 240
Step-by-step explanation:
Let's represent Aaron's age with x and
Charlene's age with x+8
x+x+8=44
2x+8=44
2x=44-8
2x=36
x=36÷2
x=18
Aaron is 18 years old.
While Charlene is 18+8=26 years old.
