The chapter 7 test will have 20-30 questions on it. Novanet!
Answer:
y = -2x - 5
Step-by-step explanation:
y = -2x + b
- To find the y-intercept, plug the values of the variables.
5 = -2(-5) + b
5 = 10 + b
- Subtract 10 from both sides.
-5 = b
Answer:
x+y=3
Step-by-step explanation:
For an equation to have no solution, their slope needs to be same and y intercept needs to be different,
so in this case where x+y=2
doing simply, x+y=3 makes a set of equation which has no solution, you can take any real value which is not 2
90 - 40 = 50
Complementary angles add up to 90 degrees.
If one angle is 40 degrees less than the other, you just put it into an equation where 40 is subtracted from 90.
The answer would then be 50 degrees.
