5x - 4y = 40
x intercept is when y = 0
5x - 4*0 = 40
5x = 40
x = 40/5
x = 8 x intercept = 8
y intercept is when x = 0
5*0 - 4y = 40
-4y = 40
y = 40/-4
y = -10
y intercept = -10
x intercept = 8, <span>y intercept = -10</span>
Answer:
When you say that two numbers are relatively prime, it means that both numbers do not have a common factor except 1. Stephen is incorrect because 38 and 40 are both multiples of 2.
Answer:
f(0) = 1
Step-by-step explanation:
f(x) indicates the "output" value present at the "input" (Output referring to the y value and input referring to the x value). So f(0) would mean the "y" value present at x = 0; however, there are two circles at x = 0. One of the dots is open(hollow) meaning that the "x" and "y" values present there are excluded. This leaves the closed(filled) dot which means that value is included and is the answer.
Answer:(-cos²x+1)x(tan²x+1)
Step-by-step explanation:
(1-cos²x)x(1+tan²x)
(-cos²x+1)x(tan²x+1)
