The coefficients for any expression is the number immediate preceding the variable in a multiplicative fashion. So in the case of 4x^2 +5x - 7, the coefficients are 4 and 5.
Answer:
n ≤ 25
Step-by-step explanation:
If n represents "a number", then "a number is a maximum of 25" translates to ...
n ≤ 25 . . . . . a number is less than or equal to 25
As x → -∞, y → -∞
as x → ∞, y → ∞
Answer:
x=5
Step-by-step explanation:
2x=10
Divide each side by 2
2x/2 = 10/2
x = 5
Answer:
3. d= 20mm
4. r= 8 in
5. d= 14 mi
6. r= 11 yd
Step-by-step explanation:
Radius is half of diameter.
Example:
What is the diameter of a circle with a radius of 4?
If r = 4, d = 8
Do radius times 2.
Example 2:
What is the radius of a circle with a diameter of 10?
D = 10, so r = 5
Do diameter divided by 2.
