It's a straight line that crosses the y-axis at the point where y=1, and it has
a slope of +2. (For every inch that it travels from left to right, it rises 2 inches.)
Multiply the number of sizes by the number of toppings. 3 * 4 = 12 different combinations.
Answer:
(2, 13)
Step-by-step explanation:
Since they both equal y, you can equal them to each other.
8x - 3 = 2x + 9
Subtract 2x from both sides.
6x - 3 = 9
Add 3 to both sides.
6x = 12
Now divide 6 on both sides.
x = 2
Now that we have found x, we need to find y. Just plug in x to the equations.
y = 2(2) + 9
y = 4 + 9
y = 13
Now, if the next equal has the same y, then both are true.
8(2) -3 = y
16-3=y
13 = y
So therefor, both x and y are true.
I'm assuming you're trying to simplify the expression?
If so, start by combining like terms.
4x+56-57
becomes 4x-1
That is the furthest you can simplify. If it had an equals sign, it would be an equation, and you would solve for x algebraically. But, since there is no equals sign, it is just an expression, and you simplify it to the best of your ability.
Hope this helps!
