Answer:
He did the complete opposite of what he needed to do
Step-by-step explanation:
The error is that when you need to find x - intercept, you need to replace the value of y with zero, not the y value.
Cause otherwise, what he did here is to find the y - intercept

Answer:
- w = 70° . . . . alternate interior angles
- x = 70° . . . . alternate interior angles
- y = 40° . . . . angle sum in a triangle
- z = ?? . . . . not enough information
Step-by-step explanation:
The alternate interior angles theorem, and the angle sum theorem can be used here.
<h3>Alternate interior angles</h3>
Alternate interior angles are found on either side of a transversal where it crosses a pair of parallel lines. They are between the parallel lines. Their vertices are at the junction of the transversal and the parallel lines. Alternate interior angles are congruent.
In this diagram, there are two pairs of alternate interior angles where the two transversals AD and BD cross parallel lines AB and CD.
At points A and D, the alternate interior angles are 70° and x, respectively. This tells you ...
x = 70° . . . . alternate interior angles theorem
At points B and D, the alternate interior angles are w and 70°, respectively. This tells you ...
w = 70° . . . . alternate interior angles theorem
<h3>Angle sum</h3>
The angle sum theorem tells you the sum of angles in a triangle is 180°. This fact can be used to find the measure of angle y.
70° +w +y = 180°
y = 180° -70° -w = 110° -70°
y = 40° . . . . angle sum theorem
There is not enough information to determine the measure of angle z.
z = indeterminate

Answer:
What is the sequence? The sequence is +4
Step-by-step explanation:
I don't know if you are asking for the ninth or tenth term of the sequence, but I'll just list them all.
-1, 3, 7, 11, 15, 19, 23, 27, 31, 35, ...
|___||___||___||____||___||____||____||____||____|
+4 +4 +4 +4 +4 +4 +4 +4 +4
So 31 and 35 are your answer!
I hope this helps!
