Answer:
138
Step-by-step explanation:
You already have all you need. Just put in it the slope-intercept form: y=mx+b where m is the slope and b is the y-intercept so
y=7x-4
Answer:
m arc PQ=66°
Step-by-step explanation:
we know that
m arc PQ=m∠PTQ -----> by central angle (because T is the center of the circle)
m∠RTS=m arc SR ----> by central angle (because T is the center of the circle)
m arc SR=66°
so
m∠RTS=66°
Remember that
m∠PTQ ≅ m∠RTS
so
m∠PTQ=66°
therefore
m arc PQ=66°
Answer:
Step-by-step explanation:
x= 0, -7
the reason that is true is because if you set each x equal to each other, you get x = 0 and x + 7 = 0 and if you subtract 7 on both sides you get x = -7
so x = -7, 0
