5*(60+3)
You should write 63 in this way 60+3
If I'm reading your question correctly: "<span>F(x)=7x+9/8x-9 when -f(x)," then all you have to do to find -f(x) would be to put a negative sign in front of ALL
of 7x + 9 / (8x-9):
9
- f(x) = -7x - --------
8x-9</span>
Answer:
orders of magnitude.
Step-by-step explanation:
We know that 900 km is equivalent to 20 cm, because we need to fit the United Kingdom length on a sheet of paper. So:
- 1 cm in a paper will be 45 km in the real ground.
Therefore, if we divide 45 km by 0.00001 km (1 cm) we will have
times to scale down.
I hope it helps you!
Answer:
(-2 , -3) and (0.6 , 4.8)
Step-by-step explanation:
y=3x +3
(x - 2)² + y² = 25
(x - 2)² + (3x +3)² = 25
x²-4x+4+9x²+18x+9-25=0
10x²+14x-12=0
5x²+7x-6=0
(x+2)(5x-3)=0
x = -2 or x = 3/5 (-0.6)
y = -3 or y = 4 4/5 (4.8)
