f(x)=2x+3
What is the value of f(−2)?
f(−2) = ?
Answer:
f(- 2) = - 1
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x), that is
f(- 2) = 2(- 2) + 3 = - 4 + 3 = - 1
For + 3, then
f(- 2) = + 3 = + 3 = 3.25
Answer: Kai picked 858 blueberries and Nico picked 78 blueberries.
Step-by-step explanation: Given that Kai picked 11 times as many blueberries as Nico and together they picked 936 blueberries.
We are to find the number of blueberries that Kai and Nico picked.
Let x and y represents the number of blueberries that Kai and Nico picked respectively.
Then, according to the given information, we have
Substituting the value of x from equation (i) in equation (ii), we get
And, from equation (i), we get
Thus, Kai picked 858 blueberries and Nico picked 78 blueberries.

A gallon consists of 4 quarts so you want to do is convert the mixed number: 2+3/4 into an improper fraction: 11/4. But you ignore the /4 part because a quart = a gallon/4. So the 4s cancel out and you're left with 11. So the answer is 11 quarts in 2 3/4 gallons.
3 inches
5 inches
9 inches
The required radius of the given cone is 3 inches which is the correct answer would be option (B).
The volume of a cone is defined as the amount of space occupied by a cone in a three-dimensional plane.
The volume of the cone (V )= 1/3πhr²
The volume of a cone is 141.3 cubic inches. The height of the cone is 15 inches.
To determine the radius of the given cone.
The volume of the cone (v) = 1/3πr²h
Substitute the values of h and v, solve for r
⇒ 141.3 = 1/3π(r)²(15)
⇒ 141.3 = π(r)²(5)
Divided by 5π into both sides of the above equation,
⇒ 141.3/5π = (r)²
⇒ 9 = (r)²
⇒ (r)² = 3²
⇒ r = 3
Hence, the required radius of the given cone is 3 inches.

-25=1/3n - 10
move -10 to the other side
sign changes from -10 to +10
-25+10=1/3n-10+10
-25+10=1/3n
-15=1/3n
multiply both sides by 3/1 to get n by itself
(-15)(3/1)=1/3n(3/1)
cross out 3 and 3 and 1 and 1, divide by 3 and 1
then becomes 1*1*1*1*n=n
(-15)(3/1)==45/1=-45
answer:
n=-45
