Answer:
$5.61
Step-by-step explanation:
Since David only has $9.39 but he needs $15.00 for his purchase. So, you would subtract the $9.39 from the $15.00 to see how much more money David needs to make this purchase.
15.00 - 9.39
When you carry out this problem, it equals $5.61.
Therefore, David needs $5.61 to be able to complete his purchase
You know slope intercept form is y=mx+b so just put in that form by:
Adding 4x to other side
2y=10+4x
Then divide by 2
Y=10/2 +4/2x
Simplify
Y=5+2x
I rearranged so x is first so your answer would be: y=2x+5
So the formula for this type of question is a(square) + b(square)=c(square)
so it would be x+30x30 = 50x50
x+900= 2500
x= 2500-900
x= 1600
since it’s you want to find the length without the root , do square root of 1600 , which is 40
So it’s B
