Answer:
36 years
Step-by-step explanation:
Let
x = Elga's age
Alvin's age = x + 7
Sum of their ages = 79
Sum of their ages = Alvin's age + Elga's age
79 = (x + 7) + x
79 = x + 7 + x
79 = 2x + 7
79 - 7 = 2x
72 = 2x
x = 72/2
x = 36
Elga's age = x = 36 years
Alvin's age = x + 7
= 36 + 7
= 43 years
Answer:
f(x)=x(x- a) (x - b) 2 that is the answer good luck
If you are writing in slope-intercept form:
You first find the slope.
Put the slope in the equation.
Substitute any point into the equation and find the y-intercept.
The angle of YWZ is equal to the angle of YWX, and angle WYX is also a right angle due to the congruency of segments WZ and WX.
Every triangle has an angle total of 180 degrees, so angle WXY is equal to
180 - (WYX + YWX)
180 - (90 + 17)
73
Angle WXY has an angle value of 73 degrees.
Sorry kid but no one gives a f go get a life how old are u 2
