Answer:
$7.58
Step-by-step explanation:
Think about it, (S+C), each flavor costs $3.97 per carton, and there's 2 cartons. $3.79 x 2 = $7.58
Answer- To determine if Y=-8 is a function, you must do the vertical line test. If you were to plot Y=-8 on a coordinate plane, you would see that at the point of (0,-8)[which is what Y=-8 is also] is on the Y axis and makes a horizontal linet hat passes through (o,-8).
Answer:
63/5
Step-by-step explanation:
when x = 8 and y = 6
the two equations become
8 = 1/10 * 6 + a & 6 = 1/10 * 8 + b
which simplify to
8 = 3/5 + a & 6 = 4/5 + b
so a = 8 - 3/5 = 37/5 & b = 6 - 4/5 = 26/5
a + b = 37/5 + 26/5 = 63/5
Answer:
y = 0.2(0.5)^x
Step-by-step explanation:
Exponential function are of the form
y = ab^x
----------------------
To find "a" plug in x = 0 y = 0.2
0.2 = a(0.2)^0
0.2 = a
-------------------------
To find "b" plug in another point and a = 0.2
using x = 2, b = 0.05
0.05 = 0.2b^2
Divide both sides by 0.20
.25 = b^2
Take the square root of both sides
0.5 = b
-----------------------------
With a = 0.2 and b = 0.5 the equation becomes
y = 0.2(0.5)^x
