Equation of a line is:
y=mx+C
------------------------
We're looking for m as m stands for gradient.
2x-6y=0 (Divide all terms by 2)
x-3y=0
3y=x
y=1/3x
y=1/3x+0
Therefore m=1/3, C=0.
Replace g for -2 and h for 5.
(2(-2) + 9(5) -5) - (6(-2) - 4(5) +2)
Taking this one at a time,
2(-2) = -4, and 9(5) = 45.
6(-2) = -12 and -4(5) = -20
(-4 + 45 - 5) - (- 12 - 20 +2)
Let’s distribute the negative symbol to the right side.
(-4 + 45 - 5) + (12 + 20 - 2)
Then, we solve!
(-4 + 40) + (12 + 18)
(36) + (30)
= 66!
You can just add the terms:
<span>(-x^2+9)+(-3x^2-11x+4) = -4x</span>² - 11x + 13
Answer:
14 km
Step-by-step explanation:
6 km in the afternoon
x km in the morning
6= x- 25%
6= 0.75x
x= 6/0.75
x= 8 km
total 6+8= 14 km
