105.0, 105%.
If one question is bonus, there are technically 20 questions on the test; 100/20 is 5, so each question is worth 5 points. 105 is 105% of 100.
Answer:
y=-2/5x-3
Step-by-step explanation:
the slope is m and the y intercept is b
Answer:
y = 3x + 5
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
The polynomial p(x) = x³ + 5x² - x - 5, can be factored and grouped and be written as <u>p(x) = (x + 5)(x + 1)(x - 1)</u>.
The given polynomial to us is p(x) = x³ + 5x² - x - 5.
We are asked to factor the polynomial by grouping.
We can do this by following these steps:
- p(x) = x³ + 5x² - x - 5.
- We group the first two terms and the next two terms to get p(x) = (x³ + 5x²) + (-x -5).
- Now, we take x² common from the first group and -1 common from the second group to get p(x) = x²(x + 5) -1(x + 5)
- Now, we take (x + 5) common from both the terms to get, p(x) = (x + 5)(x² - 1).
- Now, we right (x² - 1) as (x + 1)(x - 1). to get the polynomial as, p(x) = (x + 5)(x + 1)(x - 1).
Therefore, the polynomial p(x) = x³ + 5x² - x - 5, can be factored and grouped and be written as <u>p(x) = (x + 5)(x + 1)(x - 1)</u>.

Your graph should look exactly like the one below.
y = x + 2 (Black)
x + y = 3 (Red)
Now the solution is found in the intersection of the points, which is (0.5,2.5)
Verify:
y = x + 2
2.5 = 0.5 + 2
2.5 = 2.5 (correct)
