Your in High School, you should know quadratic formula; start by subtracting 7 from both sides making it 4x^2 - 12x -7, now solve it using the quadratic formula.
Answer: X= 7/2
X= -1/2
The number of pizzas you must order for the price to be the same is 5
<h3>How many pizzas must you order for the price to be the same?</h3>
Bob's Pizza charges = $12 for each supreme pizza
This can be represented as
y = 12x
For Mike's Pizzeria, we have
y = 8x + 20
Substitute y = 12x in y = 8x + 20
12x = 8x + 20
Evaluate the like terms
4x = 20
Divide by 4
x = 5
Hence, the number of pizzas you must order for the price to be the same is 5

Answer with explanation:
To determine the Equation of line in Point slope form
1.Choose a point on the line, such as (2, 5)
2. Choose another point on the line, such as (1, 3).
3.Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is 2.
4.Substitute those values into the point-slope form.
y-3=2(x-1)
Step 3 is incorrect because it shows an incorrect ratio for the slope.
To determine the slope we use the following formula
Instead of counting how many rights and how many ups.
