(10x-20)=(6x+8)
We simplify the equation to the form, which is simple to understand
(10x-20)=(6x+8)
Remove unnecessary parentheses
10x-20=(6x+8)
Remove unnecessary parentheses
10x-20=6x+8
We move all terms containing x to the left and all other terms to the right.
+10x-6x=+8+20
We simplify left and right side of the equation.
+4x=+28
We divide both sides of the equation by 4 to get x.
x=7

Hi there! The domain of a function refers to the values that can be validly input for x. In laymen's terms, domain is the x-values that exist on a graph of the equation.
If we were to plug in y=-2x+5 into a calculator that shows an infinite graph, we would see that the line of the equation would extend both ways infinitely! This means that all real numbers can be inputs for x, because for every x value that exists there is a corresponding y value.
This means that D. All real numbers, is your answer.
Hope it helps! :)
Answer: $10.40
Explanation:
First, find the cost of 1 box of pasta. 13/5 = 2.6, so $2.60 a box.
Next, find how many boxes there are. 48/12 = 4, so 4 boxes of pasta.
Finally, multiply 4*2.6 to get the final cost.
Answer:
18 and -2
Step-by-step explanation:
Let x = 1st no.
y = 2nd no.
(1) x + y = 16 (2) xy = -36
y = 16 - x x(16 - x) = -36
(x - 18)(x + 2) = 0
x = 18 or x = -2
y = 16 - 18 = -2
y = 16 -(- 2) = 16 + 2 - 18
The two numbers are 18 and -2
