Answer:
y = -3x
Step-by-step explanation:
(a) Slope
y = mx + b
Choose points (-3, 9) and (3, -9)
m = (-9 - 9)/(3 – (-3))
m = -18/(3 + 3)
m = -18/6
m = -3
=====
(b) y-intercept
y = mx +b
Choose point (0,0).
0 = 0 + b
b = 0
=====
(c) Equation of line
y = mx + b
y = -3x
Answer: X= 25 degrees
Step-by-step explanation:
A triangle is 180 degrees.
115+40=165
180-165=25 degrees
Answer:
Step-by-step explanation:
We have:
To solve, we will isolate the x variable. Therefore, subtract 7 from both sides:
Divide both sides by 2:
Take the square root of both sides. Since we’re taking an event root, we will need plus/minus. Therefore:
Therefore, our solutions are:
