Counting these x's they would be 11. (if living in U.S.A)
Answer:
80° , 100°, 80°
Step-by-step explanation:
∠ 1 and ∠ 2 form a straight line and sum to 180° , then
2x + 40 + 2y + 40 = 180
2x + 2y + 80 = 180 ( subtract 80 from both sides )
2x + 2y = 100 → (1)
∠ 1 and ∠ 3 are vertical angles and are congruent , then
2x + 40 = x + 2y ( subtract x from both sides )
x + 40 = 2y ( subtract 40 from both sides )
x = 2y - 40 → (2)
Substitute x = 2y - 40 into (1)
2(2y - 40) + 2y = 100
4y - 80 + 2y = 100
6y - 80 = 100 ( add 80 to both sides )
6y = 180 ( divide both sides by 6 )
y = 30
Substitute y = 30 into (2)
x = 2(30) - 40 = 60 - 40 = 20
Thus x = 20 and y = 30
Then
∠ 1 = 2x + 40 = 2(20) + 40 = 40 + 40 = 80°
∠ 2 = 2y + 40 = 2(30) + 40 = 60 + 40 = 100°
∠3 = x + 2y = 20 + 2(30) = 20 + 60 = 80°
<em><u>The solution to the inequality is:</u></em>

<em><u>Solution:</u></em>
Given inequality is:

We have to find the solution to given inequality




Simplify the above inequality


Remember that, change the inequality sign if you divide or multiply both sides by a negative number
If you divide or multiply both sides by a positive number,the inequality sign will not change



Thus the solution to inequality is found

Answer:
Because you did not give the slope, we cannot get the exact equation. However, using m as a substitute for slope, the point-slope form would be y - 7 = m(x + 4)
Step-by-step explanation:
We can find this equation through the use of the base form of point-slope form. Then we can plug in the point where we see fit.
y - y1 = m(x - x1)
y - 7 = m(x + 4)
