Answer:
1
Step-by-step explanation:
y-intercept is defined as the point where the graph crosses the y-axis. The value of x coordinate at this point is zero, as along entire y-axis, the value of x coordinate is always zero. So substituting x = 0 in the function will give us the y-coordinate of the y-intercept of the given function.

Substituting x = 0 in this function, we get:

Thus, the y-coordinate of the y-intercept is 1. Therefore the y-intercept of the function in ordered pair will be: (0, 1)
The expression is 5x - 2y
Use PEMDAS and work out the rest
x = 3 and y = 4
5 x = 5 x 3 = 15
2 y = 2 x 4 = 8
15( x ) - 8 (y) = 7
The answer is 7

Answer:
1. 7.6 = c
2. 45 = c
Step-by-step explanation:
1. 3^2 + 7^2 = c^2
9 + 49 = c^2
58 = c^2
square root both sides = 7.6 = c
2. 27^2 + 36^2 = c^2
729 + 1296 = c^2
2025 = c^2
square root both sides
c = 45
