Answer:
C
Step-by-step explanation:
I think I will answer the question the your attachment because it has full information.
The function is: y = 3*
a. The function decreases
Wrong, because the base number is 2 and it is greater than 0. The function will go up
b. y=intercept of (0.2)
Wrong, Let substitute x =2 into the function: y = 3*
= 12
c. if x increase by 1, the value of y will double
Because the base number is 2. For example:
- If x = 2, y = 3*
= 12
- If x =3, y =3*
=(3*
*)2 = 24
d. contains the point (2,4)
Wrong, Let substitute x =4 into the function: y = 3*
= 48
So we choose C
12 girls out of 19, how many out of 76
12 - x
19 - 76
Cross product:
19x= 1152
/19. /19
x= ~61
There are (around) 61 girls
Answer: y = -2x -2
Step-by-step explanation:
Making y the subject of the formula
Subtract 4 from both sides
⇒ y = -2 ( x - 1 ) - 4
y = -2x + 2 -4
y = -2x -2
Hi There!
