Answer:
11
Step-by-step explanation:
m∠1 = m∠2 {Corresponding angles}
78 - 2x = 89 - 3x
Add 3x to both sides
78 - 2x + 3x = 89
78 + x = 89
Subtract 78 from both sides
x = 89 - 78
x = 11
7.) (x, y) —> (1/2*x, 1/2*y)
Ok, so this is a spelling sort of work sheet, you need to say each word aloud and if the A in the word is long, then put it in the long A box, if it's a short sounding A, then put it in the short A box.
Hope this helps >.<
Y= 2x +3
First, you find the slope. ( use slope formula)
y2 - y1 / x2 - x1 = m (slope)
Then just put the y-axis in, add or subtract (depends on the sign)
The answer to this question is 25.
