Answer:
see below
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
5x+60 + 3x-40 = 180
Combine like terms
8x +20 = 180
Subtract 20 from each side
8x+20-20=180-20
8x= 160
Divide by 8
8x/8=160/8
x=20
5x+60 = 5*20+60 = 160
3x-40 = 3*20-40 = 20
Answer:

a) From the left, the limit is 1, since
b) From the right, it's 2, since
c) Also 2, same reasoning as in (b).
d) 1, since
e) No, neither two-sided limits exist because the respective one-sided limits do not agree.
Answer:
The expression contains two factor and each factor contains 2 terms.
Step-by-step explanation:
We are given the expression:
- A factor can be a number, variable, term, or a longer expression.
- A factor is made of of terms and can be a constant, number or a variable.
Now, the expression contains two factor and each factor contains 2 terms.
The factors of expression are:
The terms of expression are:
Use same-length line segments to solve for x and y.
... PS = SR
... 4x +4 = 7x -17
... 21 = 3x . . . . . . . . . add 17-4x
... 7 = x . . . . . . . . . . . divide by 3
... PS = SR = 4·7+4 = 32
... PQ = QR
... 5y -31 = 2y +5
... 3y = 36 . . . . . . . . . add 31-2y
... y = 12 . . . . . . . . . . . divide by 3
... PQ = QR = 2·12 +5 = 29
... PT = TR = 6·7-2·12 = 18
