Answer:
1
Step-by-step explanation:
(10-(-9)*-1)
Remember that 2 negative equal a positive. So -(-9) is positive.
(10+9*-1)
Then, PEMDAS is how you should finish this.
So, 9*-1 is -9
Then, 10-9 is 1
A.15.7
is the answer because fe is 13
The answers are in slope-intercept form, so you can see that the slope (coefficient of x) is only correct for choices b and c.
When you substitute x=3/2 into those equations, you find that b gives y=6 (correct) and c gives y=0 (incorrect).
The appropriate choice is ...
... b.) y = 2x+3
Knowing that pluto is travelling at 10,604 and the Earth travels 6.28 times faster;
6.28x=10,604 mph (where x is the speed of the earth)
x=10,604/6.28
x=1688.53 mph for the Earth
Double check by multiplying the answer found by 6.28 to see if it gives pluto's speed.
1688.53×6.28=10, 604 mph
Therefore, our solution is correct.
