8v + 8b = 240
4v + b = 54....multiply by -2
-------------------
8v + 8b = 240
-8v - 2b = - 108 (result of multiplying by -2)
------------------add
6b = 132
b = 132/6
b = 22 <== buses hold 22 students

4v + b = 54
4v + 22 = 54
4v = 54 - 22
4v = 32
v = 32/4
v = 8 <== vans hold 8 students

What are the values of a, b, and c in the quadratic equation 0 = = x2 – 3x – 2?<br> a=1 h=30-2
jek_recluse [69]

Answer:

  • a = 1
  • b = -3
  • c = -2

Step-by-step explanation:

The general form of a quadratic equation is often written as ...

  ax² +bx +c = 0

The references to "a", "b", and "c" are to the coefficients in this form. Comparing this to your equation ...

  x²-3x -2 = 0

we see that the coefficient of x², is 1, so a=1; the coefficient of x is -3, so b=-3, and the constant is -2, so c=-2.

F(x)=2^x. What is g(x)?
Alexxx [7]

The function g(x) is g(x)= (3x)^2

<h3>How to solve for g(x)?</h3>

The complete question is in the image


From the graph in the image, we have:

f(x) = x^2

The function f(x) is stretched by a factor of 3 to form g(x).

This means that:

g(x) = f(3x)

So, we have:

g(x)= (3x)^2

Hence, the function g(x) is g(x)= (3x)^2

Help asap idek what to do
daser333 [38]

So to solve this question, your goal is to find out how the way it is solved is not correct.

Your answer would be: On the third line, the student adds the 8 to both sides instead of subtracting. The way the initial equation is given is

y-(-8)=-6(x-2). After distributing the six, the student should make the 8 positive because subtracting a negative makes a positive. After solving, the equation should look like: y(+8)=-6x+12, so you would subtract the 8 from both sides instead of adding it, and solve from there.
