Answer:
There is no points of intersection
Step-by-step explanation:
∵ The slope of line u = 4 - (-8)/5 - 9 = 12/-4 = -3
∴ Its equation is ⇒ y = -3x + c ⇒ use point (5 , 4) to get c
4 = -3(5) + c ⇒ c = 4 + 15 = 19
∴ The equation of u is ⇒y = -3x + 19
∵ The slope of line v = -7 - 2/7 - 4 = -9/3 = -3
∴ Its equation is ⇒ y = -3x + c ⇒ use point (4 , 2) to get c
2 = -3(4) + c ⇒ c = 2 + 12 = 14
∴ The equation of v is ⇒y = -3x + 14
∵ The slopes of them are equal and their y-intercepted are not equal
∴ Line u is parallel to line v
∴ There is no point of intersection

Answer:
The answer would be -7/20
Step-by-step explanation:
You have (7/15) * (-3/4)
What you have to do is multiply the numerators, 7 and -3, which is -21.
Then you multiply the denominators, 15 and 4, which is 60.
Your fraction should then look like this (-21/60). *numerator/denominator
Then you simplify them by divided both numbers by 3, which gives your answer, (-7/20).
Since 7 is prime, the fraction can no longer be simplified any more.
<span>Angle 7 and 5 are vertical angles, so they're equal.
Angles 7 and 8 are supplementary, so they have to add up to 180.
2x + 15 + 3x = 180
Solve for x, then plug it into the expression for angle 7 to get you answer</span>
