Answer:
The answer is 200.
Step-by-step explanation:
The steps are :
Substitute y with 3
7x + 2(3) = 48
7x + 6= 48
Minus 6 over
7x = 42
X= 6
Hope this helps!
Answer:
Liam has 4 books. First book is 420 pages, The second book has 70 more pages than the third book while the third and fourth is 150 pages each.
150 + 70 = the second book has 220 pages
420 + 150 + 150 + 220 = 940 pages
And if its asking for the "mean" then take 940 / 4 and you will get 235
Answer: 2c²x(2c²+4c+1)
Step-by-step explanation:
y = -2(x-4)2-6
= -4(x-4) - 6
= -4x + 16 -6
y = 10- 4x
now if x is positive, x >= 0
then max value of y will be when x will nr minimum
so max y = 10- 4×0 = 10
so y = 10 at x =0 for x >=0
if x < 0 then
y will be increasing as x gets increase towards more negative. so max of y will be decided when x reaches to max negative.
