Answer:
(x+a)²-7=x²+10x+b
simplifying,we get
x²+2ax+a²-7=x²+10x+b
the coefficient of x on both sides should be equal
therefore
2a=10
a=10/2=5
also for b
a²-7=b
5²-7=25-7=b
b=18
a=5
I'm assuming that this is the complete question.
If f(x) = 3 – 2x and g(x)=1/(x+5), what is the value of (f/g)(8)? a) –169 b) –1 c) 13 d) 104
x = 8
f(x) = 3 -2xf(8) = 3 - 2(8) = 3 - 16 = -13
g(x) = 1/(x+5)g(8) = 1/(8+5) = 1/13
(f/g)(8)f(8)/g(8) = -13/ (1/13) = -13 * 13 = -169 Choice A :)
Well you can check what type of angle it is! like depending on how it is slouched like a right angle is 90° for example.
Answer:
4 bags of gold coins and 6 bags of gold coins
Step-by-step explanation:
So, Becky has 9 bags of coins
This is basically a "trial and error" equation.
Now, she has 4 bags of 8 gold coins
8×4= 32
So she has 32 gold coins
Now, she has 5 bags of 6 silver coins
5×6=30
So she has 30 silver coins.
So we add these,
30+32= 62
HOPE THIS HELPS!!!
Answer: 210 fewer beads.
Step-by-step explanation:
All you have to do is subtract the amount Diane has by Linda. And the answer you get is how many less beads Linda has. She has 210 fewer beads than Diane. 496 - 286 = 210 is the answer.
