Answer:
A. x = 6
Step-by-step explanation:
a^2 + b^2 = c^2
8^2 + b^2 = 10^2
64 + b^2 = 100
b^2 = 100 - 64
b^2 = 36
√b^2 = √36
b = 6
Answer:
5x + 3y = -21
Step-by-step explanation:
i think sorry if its wrong
(4x-7y)(4x+7y)
4x times 4x= 16x^2
-7y times 7y= -49y^2
Answer:
The graph represents a linear function that passes through the origin.
Step-by-step explanation:
Proportional functions can be represented by
, where
is some constant. They form a straight line that always pass through the origin (0,0). We can see all these characteristics in the graph, thus the graph is proportional.
