I’ll teach you how to solve 3x-5=-18
—————————————-
3x-5=-18
Move constant to the right-hand side and change its sign:
3x=-18+5
Calculate the sum:
3x=-13
Divide both sides of the equation by 3:
X=-13/3
Your Answer Is x=-13/3
Plz mark me as brainliest if this helped :)
No, it is a linear function.
Ur answer is B- 4/5 because when u subtract them u get 0.8 and then u have to turn it as a fraction then it will be 8/10 then u simplify it and u get 4/5.
Hope u get it right!
Answer: Choice A
L = 65 - 15d; discrete
===============================================
Explanation:
He starts with 65 cm of bread. After the first day he has 65-15 = 50 cm left over. After the second day he has 65-15*2 = 35 cm left over, and so on.
In general, he has 65-15d centimeters left over after d number of days have elapsed. For example, if d = 3 days pass by, then he has 65-15d = 65-15*3 = 65-45 = 20 cm left over.
So that's why the equation we're after is L = 65-15d where d is the number of days, and L is the amount left over in cm.
The number of days is discrete because we're dealing with the set of nonnegative numbers {0,1,2,3,4,...}. We can't have d = 2.5 for instance.
Because the input variable d is discrete, this automatically means L is discrete as well. Consider a finite domain such as {0,1,2,3}. This finite domain would map to the finite range {65,50,35,20}. These two finite sets are sufficient to say we have a discrete function.
A discrete function leads to a discrete graph which is simply a set of points. You would <u>not</u> connect the dots to form a straight line (simply leave the points as separate islands).
