The line with a slope of 3 is steeper, they are alike because both are at a positive incline.
To do this you equate the two and use x for hours.
So your equation looks like this: 100+15x=75+17x. Now move like terms to get 25=2x. The job will be 12.5 hours long to cost the same.
Answer: x= 2/3 - 1/3y
Explanation step by step:
Step 1: Move variable to the right hand side and change its sign.
3x = 2-y
Step 2: divide both sides of the equation by 3.
x= 2/3 - 1/3y
Answer:
(a) 99%
(b) 50%
Step-by-step explanation:
(a) All factorials after 1! have 2 as a factor, so are even. Thus 99 of the 100 factorials are even, for a probability of 99%.
__
(b) The first two sums are odd; the next two sums are even. The pattern repeats every four sums. There are 25 repeats of that pattern in 100 sums, so 2/4 = 50% of sums are even.
Answer:
The number is equal to 10
Step-by-step explanation:
Let x be the number
4(x-3)=28
x-3=7
x=10
