Where do Christmas presents originate from? Gift giving at Christmas is a Christian tradition that is widely practiced around the world. To Christians, the gifts given at Christmas are symbolic of the tributes made to the baby Jesus by the Three Wise Men after his birth during the story of the Nativity.
A) Substitution
substitute y = 5x-2 for y in the first equation and solve for x:
5x-2 = 7x-8 subtract 7x from both sides
-2x-2 = -8 now add 2 to both sides
-2x = -8 + 2 simplify
-2x = -6 divide both sides by -2
x=3
Now substitute x with 3 in either equation
y=5x-2 =5*3-2 =13
(3,13)
B) (3,13) is the point where the two lines intersect
y=mx+b is the equation of a line
The area is Base * Height
Area = b * h
b =12 3/4 in
h = 2 1/2 in
Area = 12.75 * 2.5 = 31.875 or 31 7/8 square inches.
It depends if it is negative that's being timesed by 2 more negatives because then that would make it negative but if it's positive times a negatives times a negative then it would be positive and no matter what a positive times any positives and no negatives that will be positive. Hope this helped! :)
Answer:
Assuming is (g•f)(-6)=16
Step-by-step explanation:
F(-6)=-(-6)-2=4
g(4)=4^2=16
