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.
46/7= 6.57
6.64= 6.64
√44<span>= 6.633
</span>-√45=<span>-6.70
least to great would be </span>-√45, 46/7, <span>√44, 6.64</span>
Answer:
1000 text messages
Step-by-step explanation:
y=0.05x+50
Y=0.02x+80
50+0.05x=0.02x+80
0.05x=0.02x+30
0.03x=30
1000=x

bit.
Step-by-step explanation:
It should be 4,2 because it says reflect across the x-axis which means you do the same thing but just with the other side of the x-axis
