(1 3/4) / (1/5) =
(7/4) / (1/5) =
7/4 * 5/1 =
35/4 or 8 3/4 <===
X = -4 -> y = 4
x = 1 -> y = -1
So, rate = (4-(-1)) / (-4-1) = -1
(1/2w+3) - (1/4w+4)
everything in second parentheses becomes negative
=1/2w+3 -1/4w - 4
combine like terms
=1/2w-1/4w+3-4
=1/4w-1
ANSWER: B) 1/4w-1
Hope this helps! :)
Simply plug in the value of x.
f(x) = -x² + 4x + 12
f(3) = -(3²) + 4(3) + 12 = -9 + 12 + 12 = -9 + 24 = 15
f(4) = -(4²) + 4(4) + 12 = -16 + 16 + 12 = 0 + 12 = 12
f(5) = -(5²) + 4(5) + 12 = -25 + 20 + 12 = -25 + 32 = 7
f(6) = -(6²) + 4(6) + 12 = -36 + 24 + 12 = -36 + 36 = 0
g(x) = x + 8
g(3) = 3 + 8 = 11
g(4) = 4 + 8 = 12
g(5) = 5 + 8 = 13
g(6) = 6 + 8 = 14
f(x) = g(x) when x = 4.
f(4) = g(4)
12 = 12
Answer:
1 toast costs $0.30 and 1 egg cost $0.60
Step-by-step explanation:
Let price of 1 egg be and price of 1 toast be
<u>"$1.50 for 2 eggs and one piece of toast":</u>
We can write
<u>"$.90 for one egg and one piece of toast":</u>
We can write
Now, we can solve the first equation for t and substitute that into 2nd equation and solve for e:
Now using the value of e (0.6) and putting it back in the first equation, we will get t:
Hence, 1 toast costs $0.30 and 1 egg cost $0.60
