Step-by-step explanation:
You must first know the formular for gradient then use the applied formular for slope
Answer: the ordered pair is (-14,-6)
Step by step:
x – 2y = -2 (Eq. 1)
x – 4y = 10 (Eq. 2)
Isolate x in Eq. 2:
x = -2 + 2y
Substitute that solution x in Eq. 2:
x - 4y = 10
-2 + 2y - 4y = 10
Solve for y:
-2 - 2y = 10
-2y = 10 + 2 = 12
y = -6
Then calculate value for x using the above value for y
x = -2 + 2y
x = -2 + 2(-6) = -14
The solution is (x,y)=(-14,-6)
Answer:
6 Hours
Step-by-step explanation:
No.of leaflets---no.of people---work hours
1000 ————. 4. - — — — — — — 5
1500 — — — —5 — — — — — ,— —?
If work increase, no.of people needed more
So, the required ratio is 1500/1000
If work men increase, no of hours decrease
So, the required ratio is 4/5
(1500/1000)× (4/5)×5 = 6
No.of hours required to distribute 1500 leaflets by 5 people = 6 hours
Answer:
5x + 11
Explanation:
3(x + 7) + 2x − 10
<u>Distribute</u>
(3)(x) + (3)(7) + 2x − 10
3x + 21 + 2x − 10
<u>Combine Like Terms</u>
3x + 21 + 2x − 10
(3x + 2x) + (21 − 10)
= 5x + 11
