Answer:
y=6*x+101
Step-by-step explanation:
Slope intercept form is y=mx+n, where m is the slope and n is the intercept.
Substituing in that equation the two points we get two different expressions. Now we have to solve a 2x2 system of equations.
I decide to solve it through substraction (literally one expression minus the other). That way we cancel out the n and obtain the value of m.
Now that we have m we plug in the value of m in one of the expressions to obtain the value of n.
To express the final equation we just plug in the values of m and n in the expression y=mx+n!
The word form of 3.4 is three and four-tenths. Expanded form is 3+.4.
Answer:
D
Step-by-step explanation:
The equation of an exponential function is
y = a
To find a and b, substitute (1, 12) and (2, 36) into the equation
(1, 12) → 12 = ab → (1)
(2, 36) → 36 = ab² → (2)
divide (2) by (1)
=
b = 3
substitute b = 3 into (1)
12 = 3a ⇒ a = 4
f(x) = 4 → D
