Answer:

Graph B

Step-by-step explanation:

The solutions to a quadratic equation are the points on which we have the graph of the curve touching the x-axis

Now the first thing we will do here is to solve the quadratic equation graph;

x^2 + 4x -12 = 0

x^2 +6x - 2x -12 = 0

x (x + 6) -2(x + 6) = 0

(x-2)(x + 6) = 0

x = 2 or -6

So the graph that touches the x-axis at the points x = 2 and x = -6 is the solution to the quadratic equation

Graph B is the closest to what we have as answer

A school snack bar sells a mix of granola and raisins. The mix includes 2 pounds of granola for every 3 pounds of raisins. How m
kifflom [539]
The easiest way to solve a problem like this is to cross multiply and solve 

The problem gives us a ratio 
2 pounds of granola = 3 pounds of raisins 
which makes a ratio of \frac{2}{3}
The other ratio is 
? pounds of granola = 24 pounds of raisins
which makes a ratio of \frac{x}{24}

To solve, set them equal to each other ...
\frac{2}{3} =  \frac{x}{24}

Now we must cross multiply...
To cross multiply, we multiply 2 and 24 
and we multiply 3 and x 
Now we have an equation to solve!
3x = 48 
To solve and get your final answer, divide...
x = \frac{48}{3}

x = 16
You'll need 16 pounds of granola

Tricia got a 6% raise on her weekly salary. The raise was $30 per week. What was her original weekly salary in dollars per week?
serious [3.7K]

Answer:   Original salary = $500  

Step-by-step explanation:  Tricia got a 6% raise on her weekly salary. The

raise was $30 per week.  

Let x be the original salary  

x times the raise percentage = raise amount  

6%= 6/100=0.06, raise amount = 30    

Now we solve for x  

Divide by 0.06 on both sides    

Original salary = $500
