The slope of a line going through points (5,7) and (3,1) is 6/2 so 3/1 = slope of 3
X-y=6
x²-y²=192
(x+y)(x-y)=192
(x+y)6=192
x+y=32.
x=6+y.
6+y+y=32
2y=26.
y=13.
x-13=6
x=19.
Therefore the anwer is: x=19, y= 13.
I got -512 because the pattern is adding -9.
I hope this helps! :D
Answer:
Step-by-step explanation:
<u> m∠SQT is substituted by 180° at step 5</u>
- 4 m∠SQV + m∠VQT = m∠SQT Angle Addition Postulate
- 5 m∠SQV + m∠VQT = 180° Substitution Property of Equality
- 6 m∠VQT + m∠ZRS = 180° Same-Side Interior Angles Theorem
