Answer:
does it tell you what x is equivalent to?
Step-by-step explanation:
Answer:
y=19.2. because x=8 when x multiply by 1.6, so y should multiply by 1.6 to get 19.2
Step-by-step explanation:
Vicki: 10 + 10 + 20 = 40
Johnny: 10 + 10 + 30 = 50
50 - 40 = 10 birds
Write the Inequality
A number b times -16 is greater than 5.
A number b is a variable... b.
Times means multiply.
-16 is what you are multiplying b by.
Is greater than means the greater than symbol.
5 is what the past statements are greater than.
So this is the inequality.
-16b > 5
Solve the Inequality
You need to isolate b.
To do this, divide each side by -16. You do this because b is being multiplied by -16. You know that any number divided by that number equals 1, canceling the number.
-16b ÷ -16 = b
5 ÷ -16 = -5/16
So you get b > -5/16
So to make the inequality true, b must be more than -5/16.
Or as an inequality...
b > -5/16

Answer:
B, E
Step-by-step explanation:
The table tells you that f(0) = 3/2. (0 is found in the x-column; 3/2 is found in the f(x) column.)
__
You can find f(4) by evaluating the formula.
f(4) = 1/2·4 +3/2 = 4/2 +3/2
f(4) = 7/2 . . . . agrees with last answer choice
