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.
Yes, both have the 110 degrees angle, and according to some theorem, the interior angles formed by the intersection of the 2 lines, they are also congruent angles (the y angles). All that remains is the x angle, which is congruent to the other angle.
3 gallons because 3/4 of a gallon covers 1/4 of a wall so you multiply the amount of gallons used for a wall times 4 which is 12/4 (keep the denominator the same ) and then divide 12 by 4 which is 3 gallons
It has six sides and six angles.
Lengths of all the sides and the measurement of all the angles are equal.
The total number of diagonals in a regular hexagon is 9.
The sum of all interior angles is equal to 720 degrees, where each interior angle measures 120 degrees.
