Answer:

Step-by-step explanation:
The standard form of a linear equation is
.
The given line has equation:

This is the point-slope form of the given line.
To find the standard form, we clear the fraction

We expand the parenthesis now to get:

We group the variables on the LHS and the constants on the RHS.


Multiply through by -1

This is of the form:
.
Answer:

Answer:
B. 50
Step-by-step explanation:
The alternate interior angles at transversal t across parallel lines AB and CD will be congruent.
2x +40 = x +90
x = 50 . . . . . . . . . . . subtract x+40
The value of x is 50.
_____
<em>Check</em>
2x+40 = 2×50 +40 = 140
x+90 = 50 +90 = 140 . . . . so the obtuse angles are congruent, as they should be
___
<em>Additional comment</em>
The lines AB and CD are not shown as being parallel. We have to assume they are, or we cannot work the problem.
Answer:


Step-by-step explanation:
We are given


Calculation of P+Q:

now, we can combine like terms



Calculation of Q-P:

Firstly, we will distribute negative sign

now, we can combine like terms


f(2) This means that x is 2, so you plug in 2 for x in the equation




Your answer is D
