Answer:
Step-by-step explanation:
∠NPK = 180° {straight line}
∠NPM + ∠MPL + ∠LPK = 180°
∠NPM + 63 +90 = 180
∠NPM + 153 = 180
∠NPM = 180 - 153
∠NPM = 27°
∠JPK = ∠NPM {Vertically opposite angles}
∠JPK = 27°
∠NPK = 180° {Straight line angle}
∠NPJ + ∠JPK = 180
∠NPJ + 27 = 180
∠NPJ = 180 - 27
∠NPJ = 153
Coefficient is the correct answer
Answer:
For the first equation
5x-y=74
5(12)-14= 46 which is not =74
Then the second is the equation
Or you calculate it also
3x+y=50
3(12)+14=50
Sutable equation this is
Answer:
6 square inches
Step-by-step explanation:
6(1*1) = <u>6 in^2</u>
For x values 1 unit either side of the vertex, the value of y is 2 more than it is at the vertex.
a = 2
_____
More formally, The graph appears to go through the point (4, 1). Substituting these values for (x, y) in the equation, we get
1 = a(4-3)² -1 . . . . substitute for x and y
2 = a . . . . . . . . . . add 1 and simplify
