Answer: 1
Step-by-step explanation:
-11, -7, -3...
you add 4 each time so the next number would be 1
For this question, we want to find out the greatest amount of area of pizza for the least amount of money:
So we have two pizzas with a 10 in. diameter. Let us take one of those pizzas.
The formula for area of a circle is
![\pi r ^2](https://tex.z-dn.net/?f=%20%5Cpi%20r%20%5E2)
; So the area for one of these 10 in. pizzas would be
![\pi (5)^2](https://tex.z-dn.net/?f=%20%5Cpi%20%285%29%5E2)
or 25
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
.
We have two of these pizzas, so the total area that we would get with $14 would be 25
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
*2 or 50
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
.
For the second case, we have one pizza with a 14 in. diameter.
The area of this pizza will be
![\pi (7)^2](https://tex.z-dn.net/?f=%20%5Cpi%20%287%29%5E2)
or 49
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
.
So for $15 we can buy 49
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
worth of pizza.
The best deal would be to buy the two medium pizzas of 10 inch diameter, because for $14, you get 50
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
.

Answer:
B; (2,-4)
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
So from the question, when we look at the given equation, its slope is -1/2
mathematically, when two lines are perpendicular, the product of their slopes is -1
thus;
m1 * m2 = -1
m2 * -1/2 = -1
-m2 = -2
m2 = 2
The general equation form is;
y-y1 = m(x-x1)
where (x1,y1) = (4,0)
y-0 = 2(x-4)
y = 2x - 8
So, now we look at the point that will work for this equation
For the line that will work, if we substitute its x-value, we get the y-value
Let us take a look at option B
y = 2(2) -8 = 4-8 = -4
we can see that (2,-4) works
