Step-by-step explanation:
y=2x−3
y=x+2
y=-3
x=3/2
for the second line
y=2
x=-2
2 x 5 x r will give you this as well as 10r
Answer:
Step-by-step explanation:
Let Carl do the job in c days, Anne- in a, and Bob in b days
Then the portion of job they can do is 1/c, 1/a and 1/b
<u>As per given we have below equations:</u>
- 1/c + 1/b= 1/6
- 1/a + 1/b = 1/3
- 1/a + 1/c = 1/5
<u>Sum of all 3 equations gives us:</u>
- 2(1/a + 1/b + 1/c) = 1/6 + 1/3 + 1/5
- 2(1/a + 1/b + 1/c) = 5/30 + 10/30 + 6/30
- 2(1/a + 1/b + 1/c) = 21/30
- 2(1/a + 1/b + 1/c) = 7/10
- 1/a + 1/b + 1/c = 7/20
It means all three together can complete 7/20 of the job in one day
<u>The rest of the job is done by Anne and Bob:</u>
<u>As Anne and Bob can do 1/3 of the job in one day, they need time to complete the rest:</u>
<u>Add 1 day to this to find overall time:</u>
- 1 + 39 /20 = 59/20 days or 2.95 days
Answer:
y = x - 16
Step-by-step explanation:
The <em>y-intercept</em> is the value of the function when x = 0.
If f(x) = x - 16, f(0) = 0 - 16 = -16.
A is <em>wrong</em>, because f(0) = -16(0) + 1 = 0 + 1 = 1.
B is <em>wrong</em>, because f(0) = 16(0) + 1 = 0 + 1 = 1.
D is <em>wrong</em>, because f(0) = 0 + 16 = 16.
=>(hypotenuse)^2=(base)^2+(perpendicular)^2
=>(h)^2=(15)^2+(8)^2
=>(h)^2=289
=>h=√289
=>h=17 yd
