A function will not have any repeating x values...it can have repeating y values, just not the x ones
{(0,2),(3,8),(-4,-2),(3,-6),(-1,8),(8,3)}
u would have to remove one of the sets of points that has 3 as its x value....so either remove (3,8) or (3,-6)....because with both of them in there, u have repeating x values
Answer:
Age of younger brother is 14 years..
And age if elder brother is 29 years.
Step-by-step explanation:
Let us denote 'x' as the age of smaller brother,
then, the age of younger brother will be x+15 years.
Equation formed:-
x+x+15 =43
2x+15 = 43
2x = 43-15
2x = 28
X = 28/2
X = 14
Age of younger brother is 14 years.
Age of elder brother = x + 15
Age of elder brother 14 + 15 = 29 years.
Answer:
x = 18°, ∠A = 110°
Explanation:
As the lines are parallel, their sums of total interior angle is 180°
∠A + ∠B = 180°
5x +20° +9x-92° = 180°
14x -72° = 180°
14x = 180° + 72°
14x = 252°
x = 18°
Solve for angle A:
∠A = 5x +20°
∠A = 5(18) +20
∠A = 110°
