Answer:
(-1, -1)
Step-by-step explanation:
I can't graph it, but I can give you 2 points. Graph the line passing through (-1, -1) and (0, 3) and another passing through (-1, -1) and (0, -5).
The problem is translated into
14=_÷56
56÷14=4
100÷4=2
So the answer is 25%
Answer:
B
Step-by-step explanation:
y and x + 20 are corresponding angles and are congruent, then
y = x + 20 → (1)
2x - 10 and y are adjacent angles and supplementary, sum to 180°, so
2x - 10 + x + 20 = 180, that is
x + 10 = 180 ( subtract 10 from both sides )
x = 170 ( multiply both sides by 2 to clear the fraction )
5x = 340 ( divide both sides by 5 )
x = 68
Substitute x = 68 into (1)
y = (68) + 20 = 34 + 20 = 54° → B
