Hey need to sell 1200+ more because if they want more than $3100 and they already have $700 they need $2400 and divide that by 2.

Answer:

1,200 candy bars

Step-by-step explanation:

First we find how much many they need to raise:

3100 - 700= 2400

Then we take this amount and divide it by the cost of 1 candy bar:

2400 ÷ 2 = 1,200 candy bars {looks like they have a long way to go! ;)}

Solve the following equations for x, if possible. check your solutions. 6/dividex+2 = 3/4
SOVA2 [1]

Solving \frac{6}{x+2}=\frac{3}{4} we get x=6

Step-by-step explanation:

We need to solve \frac{6}{x+2}=\frac{3}{4}

Solving:

Cross multiply both terms:

4*6=3(x+2)\\24=3x+6\\3x=24-6\\3x=18\\x=18/3\\x=6

Verifying the solution:

Putting x=6 in the question given:

\frac{6}{x+2}=\frac{3}{4}

\frac{6}{6+2}=\frac{3}{4}

\frac{6}{8}=\frac{3}{4}

\frac{3}{4}=\frac{3}{4}

Solving \frac{6}{x+2}=\frac{3}{4} we get x=6

Given the following three points, find by hand the quadratic function they represent.
RideAnS [48]

Answer:

The equation is;

f(x) = -2·x² + 5·x - 1

Step-by-step explanation:

The general form of a quadratic equation  or function f(x) is, f(x) = y = a·x² + b·x + c

Given that the points representing the quadratic function are;

(-1, -8), (0, -1), (1, 2) which  are of the form (x, y)

When x = -1, f(x) = y = -8

Plugging in the above values into the general form of a quadratic function, we have;

-8 = a·(-1)² + b·(-1) + c = a - b + c

-8  = a - b + c.........................(1)

When x = 0, y = -1, we have;

-1 = a·(0)² + b·(0) + c = c

c = -1.......................................(2)

When x = 1, y = 2, which gives;

2 = a·(1)² + b·(1) + c = a + b + c

2 = a + b + c........................(3)

Adding equation (1) to equation (3), we have;

-8 + 2 = a - b + c + a + b + c

-8 + 2 = 2·a + 2·c

From equation (2) c = -1, we get;

-8 + 2 = -6 = 2·a + 2·c = 2·a + 2 × (-1)

-6 = 2·a - 2

-4 = 2·a

a = -2

From equation (3), we have

2 = a + b + c

Substituting the values of a, and c gives;

2 = -2 + b - 1

b = 2 + 2 + 1 = 5

b = 5

The equation is therefore;

f(x) = -2·x² + 5·x - 1.
