Find the x and y intercepts of the equation 8x+y=-9
Juliette [100K]

Answer:

see explanation

Step-by-step explanation:

To find the intercepts, that is where the graph crosses the x and y axes.

• Let x = 0, in the equation for y-intercept

• Let y = 0, in the equation for x-intercept

x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept

y = 0 : 8x + 0 = - 9 ⇒ x = - \frac{9}{8} ⇒ ( - \frac{9}{8}, 0) ← x- intercept

Pls help BYU question Geometery Transversal,parallel lines
Rufina [12.5K]

Answer:

<18 = 40

Step-by-step explanation:

<3 = <19 since they are alternate exterior angles and alternate exterior angles are equal for parallel lines cut by a transversal

<19 = 140

<19+<18 = 180 since they form a straight line

140 + <18 = 180

Subtract 140 from each side

140-140 + <18 = 180-140

<18 = 40

solve it:
6×2-(5-3)
12-(5-3)
12-2
10
