Answer:b
Step-by-step explanation:
Answer:
m<ABE = 115.5°
m<DBE= 25.5°
Step-by-step explanation:
m<DBC= 90°
m<DBE + m<EBC= 90°
m<DBE +64.5°= 90°
m<DBE = 90°-64.5°
m<DBE = 25.5°
m<ABE = m<ABD + m<DBE = 90°+25.5° = 115.5°

Answer:
A. y=x-3
B.y=x-3
Step-by-step explanation:
Okay so essentially, the first thing you need to do is find the slope and y intercept for each equation. To find the slope, I like to look at the two points and divide the rise (How much it goes up or down) by the run (How much it moves left or right). For A the rise is 6 and the run is 4, so the slope is 6/4 or 3/2. To find the equation for A, you also need the y-intercept which is just the y value (how high up or down) it is when it crosses the y axis. In graph a, this is at -3. Because the equation of a line is y=mx+b (m being slope and b being y intercept), we know the equation for a is y=x-3. We can do the same thing for B. The rise is -3 and the run is 4, so the slope is -3/4. The y value when x is equal to zero is 2, so that is the y intercept. The equation is y=x-3
