Answer:No
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
slope intercept form = y=mx +b
where m would be the slope and b is the y intercept
equations would be:
cool cars: y = 179x +1999
awesome autos: y = 249x
I would say that your answer is 22
Answer:
give each charity $60
Step-by-step explanation:
$814 to divide equally to 5 charities.
From 814 if we give -100, -100, -100, -100, -100, we have left 314 to split in 5
the most useful next step is to give each charity $60
From $814 if we give -100, -100, -100, -100, -100
-60, -60, -60, -60, -60
we have left now:
814 -5*100 -5*60 = 814-500-300 = $14 left to split among the 5 charity.
