<h3>
Answer: b = 4 and c = 7.</h3>
===============================================
Explanation:
Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.
The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.
Plug those three values into the vertex form below
y = a(x-h)^2 + k
y = 1(x-(-2))^2 + 3
y = (x+2)^2 + 3
Then expand everything out and simplify
y = x^2+4x+4 + 3
y = x^2+4x+7
We see that b = 4 and c = 7.
Answer:
15n=135
Step-by-step explanation:
first, you need to know how much of the total amount is the money needed for soccer balls, to find this you take the amount of a soccer ball and multiple it by the amount of people
14×15=210
then you subtract that from the total amount to get the amount spent on jerseys.
345-210=135
to get the amount of each jersey you take 135 and divide by the amount of people
135÷15=9
Given:
1 Van and 4 buses filled with 195 students.
1 Van and 5 buses filled with 241 students.
Let x and y be the number of students in Van and number of students in bus.
Subtract equation (1) from equation (2)
Substitute y=46 in equation (1)
Number of students that van can carry is 11.
Number of students that bus can carry is 46
Answer:
The answer to your question is Volume = (1/3)(x²)(x + 2)
Step-by-step explanation:
Data
length = x
height = x + 2
Volume = ?
Formula
Volume = 1/3Ab h
Process
1.- Calculate Ab
Ab = length x length
-Substitution
= (x)(x)
-Simplification
= x²
2.- Substitution
Volume = (1/3)(x²)(x + 2) or (1/3)(x³ + 2x²)
