in order to find the y-intercept of an equation, we must just make x=0.
So:
y = -4x-5
y = -4*0 -5
y = -5
Answer: -5
Use an addition or subtraction formula to find the exact value of the expression, as demonstrated in example 1. tan(105°)
Answer:
2 students failed the test.
Step-by-step explanation:
There are 40 students and 95% passed. 95% is also equal to 0.95. Since we are looking for the students who failed, subtract 1.00 - 0.95. You get 0.05. The percentage of students who failed is 5%. Multiply 0.05 times 40 to get 2. This is the amount of students who failed.
