This question would be a lot better if you had actually included the exercises. When a question talks about other questions that you already did, you need to include those too. Otherwise we don't know what the question is talking about. Fortunately I was able to figure it out without seeing the exercises, but just for future reference, you should include that extra information.
When two addends(things you add together) are negative, adding them is a lot like adding positive numbers; you just have a negative sign on the sum. For example,
4 + 5 = 9
-4 + -5 = -9
8/8 - 6/8 = 2/8 =1/4
1/4 (25%) is the not amount
Hope that helped!
Answer:
Step-by-step explanation:
The parallel lines have the same slope.
We have:
y = 1/2x + 5.
Therefore, the line has the equation:
y = 1/2x + b
Put the coordinates of the point (4, -5) to the equation:
-5 = (1/2)(4) + b
-5 = 2 + b <em>subtract 2 from both sides</em>
-5 - 2 = 2 - 2 + b
-7 = b → b = -7
Finally we have:
y = 1/2x - 7
Answer: D
<u>Step-by-step explanation:</u>
A. False
f(x): x → -∞, y → -∞
g(x): x → -∞, y → 1
B. False
at x = -1, f(x) = -7
at x = -1, g(x) = 1.5
C. False
refer to A
g(x) → 1 and f(x) → -∞ so g(x) > f(x)
D. TRUE
It is hard to tell from the graph so plug in a value to check.
f(10) = 5(10) - 2
= 50 - 2
= 48
g(10) = 2¹⁰ + 1
= 1024 + 1
= 1025
g(10) > f(10)
