Answer:
Step-by-step explanation:
Given:
1. 1/5x - 1/3y = -1
2. -3/4x +1/3y = 12
Multiplying equation 1 by 15 and equation 2 by 12
3. 3x - 5y = -15
4. -9x + 4y = 144
and then Solving both equations simultaneously, since x = -20 as stated in the question and by confirmation,
Using equation 3 or 4 to solve for y,
3(-20) - 5y = -15
-5y = 60 - 15
y = 45/-5
= -9
y = -9
I’m pretty sure it would be red
Step-by-step explanation:
slope/gradient
1 - (-4) / 4 - 0 = 5/4
y-intercept is -4 (this is the dot on y)
so the line equation is
y = 5/4x - 4 answer d
1: the one that looks like an x
2:regular pentagon
3: 4
4: 1
5: 1 line of symmetry
