Answer:
Step-by-step explanation:
Calculate the slope from 2 points.
Substitute either point into the equation. You can use either (3,7) or (5,11)
Solve for b, which is the y-intercept of the line.
Substitute b, -1, into the equation from step 2.
2q + 2p = 1 + 5q
-3q + 2p = 1
-3q = 1 - 2p
3q = 2p - 1
q = (2p -1)/3
remember the priorities of the different mathematical operations
1. brackets
2. exponents
3. multiplications and divisions
4. additions and subtractions
so,
14 + 14/7 = 14 + 2 = 16
put them as substitutes
7y^2
x=60 and the missing angle is 140
40 × 2x + 20= 180
60 + 2x =180
2x=120
x=60
2(60)+20=140
