Answer:
x = 10 and y = 7
Step-by-step explanation:
Equalateral triangle means all sides are equal.
x = 10, easy
make y + 3 = 10
y = 7
Easy, no real math needed. lol
60 because all of the sides are equal
Hi there!

Find the y-intercept by substituting in 0 for x:
f(0) = 0² + 2(0) + 3
Simplify:
f(0) = 3
Increasing function is any function whose value increases with respect to an increase in the variables.
Decreasing function is any function whose values are decreases with respect to an increase in the variables.
I think it would be B ?? Because it’s the shortest one ♀️
