Step-by-step explanation:
m= (4-0)/(2-1)
=4
y-int=1
y=mx+c
y=4x+1
(7+y)+z
Step-by-step explanation:
this is to separate the sum of 7 and y from z
Answer:
The sum is
Step-by-step explanation:
Assuming we are finding the sum of :
3e + 7 - e and 2e + 10 + 2e -3
Then we set up the addition as follows:
We group similar try to get:
We now combine the similar terms to obtain:
Therefore the sum is
9514 1404 393
Answer:
- 89 in a restaurant
- 45 in a car
- 59 at home
Step-by-step explanation:
Let r, c, h represent the numbers of meals eaten in a restaurant, car, and at home, respectively. The problem statement tells us of the relations ...
r + c + h = 193
-r + c + h = 15
r + 0c -h = 30
Add the last two equations:
(-r +c +h) +(r -h) = (15) +(30)
c = 45
Add the first two equations:
(r + c + h) +(-r + c + h) = (193) +(15)
2c +2h = 208
h = 104 -c = 59 . . . . solve for h, substitute for c
The last equation can be used to find r.
r = 30 +h = 30 +59 = 89
89 meals are eaten in a restaurant; 45 meals in a car; and 59 at home.
