First, calculate f(g(x))==> you plug (5x+4) in the value of x in f(x)
==>f(g(x))= 8-[10(5x+4)===>8-50x-40===>f(g(x))= -50x + 32
& f(g(-2))= -100+32 =68.
There is a mistake in your answers, it should be 68 & not 78
The value H makes the equation true
Answer:
3/50
Step-by-step explanation:
Multiply across the fraction- First start with the numerator digits (-1, 3, and -2)
-2*-1= 2 and 2*3= 6 So you should have 6 as your numerator
Now look at the denominator digits (4, 5, and 5)
Multiply across and you should get 100 as your denominator
You now have 6/100 but you are not done yet! Don't forget to simplify the fraction to get your final answer
Both 6 and 100 are divisible by 2 (6 divided by two is 3, and 100 divided by two is 50)
Thus, your final answer should be 3/50!
Answer:
y varies directly as x
y=kx
12=k×6
k=12/6
k=2
When x=8 and y is unknown
y=kx
y=2×8
y=16
(8r⁶s³ - 9r⁵s⁴ + 3r⁴s⁵) - (2r⁴s⁵ - 5r³s⁶ - 4r⁵s⁴)
8r⁶s³ - 9r⁵s⁴ + 4r⁵s⁴ + 3r⁴s⁵ - 2r⁴s⁵ - 5r³s⁶
8s⁶r³ - 5r⁵s⁴ + r⁴s⁵ - 5r³s⁶
