Step-by-step explanation:
y = -6x + 10 (1)
-5x + y = -1 (2)
Sub (1) into (2)
-5x + (-6x + 10) = -1
-5x - 6x + 10 = -1
-11x = -11
-11x/-11 = -11/-11
x = 1
Sub x = 1 into (1)
y = -6(1) + 10
y = -6 + 10
y = 4
Answer:
-5/4
Step-by-step explanation:
Pick two points on the line
(-4,0) and (0,-5)
We can use the slope formula
m = (y2-y1)/(x2-x1)
= ( -5 -0)/(0 - -4)
= (-5-0)/(0+4)
= -5/4
She will get 23 books.
So, first, you take the shipping away to get $93.05,
then you divide $93.05 by $3.95 which equals 23.55
and you can't have half a book; so it's 23!
Step-by-step explanation:
ok, logic
all of them are parabolas
1st and 3rd are opening up, so they defenitely increase, so no
decraseing
the vertex hs to be be at x=-4
y=a(x-h)^2+k
h has to be -4
y=a(x+4)^2+k
the answer is 2nd one or f(x)=-(x+4)^2+4
