Answer:
B) 25x + 50, where x is the number of hours .
Solution:
Let x be the number of hours editor takes to edit 3 essays.
The editor is paid $25 an hour .
Amount earned in x hours = 25x
Additional bonus given after edition of three essays = $50.
Total amount earned by the editor = 25x+50
The right option is :
B) 25x + 50, where x is the number of hours
I believe the answer is 40%
Not entirely sure, hope I helped though!
3x+3y=-3
divide both sides by 3 for ease
x+y=-1
now eliminate x's
multiply that equation by 2 and add to other one
2x+2y=-2
<u>-2x+y=2 +</u>
0x+3y=0
3y=0
y=0
x+y=-1
x+0=-1
x=-1
(x,y)
(-1,0)
I am not sure about the formula but if you subtract 8,884 from 10,712 you get 1,828. Then, if you divide that by 4 you get 457. 457 fph(feet per hour) should be the climbers vertical speed.
Answer:
(y + 1) • (y - 4)
Step-by-step explanation:
Trying to factor by splitting the middle term
1.1 Factoring y2-3y-4
The first term is, y2 its coefficient is 1 .
The middle term is, -3y its coefficient is -3 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 1 • -4 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .
-4 + 1 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
y2 - 4y + 1y - 4
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (y-4)
Add up the last 2 terms, pulling out common factors :
1 • (y-4)
Step-5 : Add up the four terms of step 4 :
(y+1) • (y-4)
Which is the desired factorization
Final result :
(y + 1) • (y - 4)
