Answer:
2
Step-by-step explanation:
Use the formula: change of y over change of x.
When you do that, your systems should look like this:
x1 = 2
y1 = 4
x2 = 6
y2 = 12
After that you plug these number into the corresponding variable.
(12 - 4) / (6 - 2) = 8/4 which equals 2.
Step-by-step explanation:
So he sold 33.
29 had pepperoni and of these 29, 15 had also sausage. SO first, to find out how many pepperoni pizzas only he sold you have to substract.
29-15= 14
14pepperoni pizzas
15 pepperoni and sausage pizzas.
Now we add 14 + 15 = 29
Now we do 33-29= 4
So the final answer to the question is:
10 pizzas more
Both equations are equal to y, so set them equal to each other forming an equation in x
2x+4=x-3
-x -x
1x+4= -3
-4 -4
x= -7
You just plug in the value of x which is -7
Y= -7-3
Y= -10
Answer:
b = 4
Step-by-step explanation:
a + 3b = 13
a + b = 5 .....multiply by -1
=============
a + 3b = 13
-a - b = -5 (result of multiplying by -1)
=============add
2b = 8
b = 8/2
b = 4 <====
a + b = 5
a + 4 = 5
a = 5 - 4
a = 1
