Answer:
The first equation, sorry can’t explain.
Answer:
Step-by-step explanation:
discriminant = (-13)² - 4·2·15 = 49
discriminant > 0 so there are two real roots
Y = 5/4x + 2
y - (-3) = 5/4 ( x - (-4))
1. Distribute 5/4
y + 3 = 5/4x + 5
2. Subtract three to collect like terms
y = 5/4x + 2
Answer:
The answer is 75 degrees
Step-by-step explanation:
All triangles interior angles will at up to 180. 52.5+52.5= 105. 180-105= 75 degrees.
