Answer:
y = x + 3
Step-by-step explanation:
y = mx + b
y = mx + 3 (the y-intercept was given (0,3))
= =
y = x + 3
Answer:
0.08333333... or 0.0834
Step-by-step explanation:
Opposite sides of a rectangle are congruent
10 + 2x = 18
2x = 18 - 10
2x = 8
x = 8/2
x = 4
Answer:
-9
Step-by-step explanation:
The triangle has two sides that are the same, so it is an isosceles triangle. Therefore, the base angles are the same.
Angles of a triangle add up to 180°, so:
70 + (x + 64) + (x + 64) = 180
70 + 2x + 128 = 180
2x = -18
x = -9
