So it would be 1.2=X-0.4 and solve to get your answer. Output means the y-intercepts.
<h3>Answer is -9</h3>
=================================
Work Shown:
(g°h)(x) is the same as g(h(x))
So, (g°h)(0) = g(h(0))
Effectively h(x) is the input to g(x). Let's first find h(0)
h(x) = x^2+3
h(0) = 0^2+3
h(0) = 3
So g(h(x)) becomes g(h(0)) after we replace x with 0, then it updates to g(3) when we replace h(0) with 3.
Now let's find g(3)
g(x) = -3x
g(3) = -3*3
g(3) = -9
-------
alternatively, you can plug h(x) algebraically into the g(x) function
g(x) = -3x
g( h(x) ) = -3*( h(x) ) ... replace all x terms with h(x)
g( h(x) ) = -3*(x^2 + 3) ... replace h(x) on right side with x^2+3
g( h(x) ) = -3x^2 - 9
Next we can plug in x = 0
g( h(0) ) = -3(0)^2 - 9
g( h(0) ) = -9
we get the same result.
Answer:
19.5
Step-by-step explanation:
If C is the midpoint of AD, and AC=13 then AD = 2 x 13 = 26
If B is the midpoint of AC, then AB = 13 ÷ 2 = 6.5
So BD = AD - AB = 26 - 6.5 = 19.5
600 homes dont have smoke alarms
3/5 is equivalent to 900/1500
1500-900 equals 600
