Here's a diagram showing how to combine angles LDA (in red) and angle ADE (in blue). Hopefully it becomes a bit clearer why these two angles add up to line segment LE. Erase the shared segment DA if it helps show LE better.
See attached image below.
Unsure of what you want. y=x-3/7 is already in standard form: y = 1x - 3/7.
The slope is 1 and the y-intercept is -3/7.
If you are given the measure of angle 4, then we know angle 2 is equal since it is a vertical angle. The angle of a line is 180 degrees, so subtract the measure of angle 4 (and/or 2) which will give you the angle measure for both angle 1 and 3, since those are also equal due to vertical angles. Hope that helped! :)
Answer:
y = - 750
Step-by-step explanation:
Given
y = x³y² ← substitute x = - 5, y = - 3 into the expression
= × (- 5)³ × (- 3)²
= × - 125 × 9 ( cancel the 3 and 9 )
= 2 × - 125 × 3
= - 750
