Answer:
3. 102
4. c
Step-by-step explanation:
For number 3:
(c^2 - a) + b becomes (10^2 - 3) + 5
10^2 = 100
100 - 3 + 5 = 102
For number 4:
Usually when you see distributive property, you're multiplying into parentheses. This time you're factoring out.
20c - 8d
It's not a, because that would be 20c + 8d
It's not b, because that would be 20c -32d
It is c, because 4 x 5c = 20 c and 4 x -2d = -8d
It's not d, because that would be 20c- 8cd
Answer:
2(4a + 1)
Step-by-step explanation:
combined like terms: 4a + 6a - 3a and 5 + 3 - 6
when you combined these 2 terms, it's 8
a

2 = 2(4a + 1)
your choices:
2(8a + 1) = 16a + 2 ( not what we are looking for)
2(8a + 2) = 16a + 4 ( not what we are looking for)
2(4a + 1) = 8a + 2 ( the answer that we are looking for)
8a + 4 ( we are looking for 8a+ 2 not 8a + 4)
Therefore, 2(4a + 1) is the correct answer
Answer:
here is your correct answer and listen question no four option are incorrect
Slope formula is suitable if you know exactly two points of the line. But if the points are intercepts, intercept formula will be more efficient.
Instead of making the negative number into the calculation, my habit is to settle the minus sign before the calculation, which makes life easier.
Answer:
(5, 2), (5, 1), (2, 1), (2, 2)
Step-by-step explanation:
When rotated 90° CCW about the origin, a point is transformed by the rule ...
(x, y) ⇒ (-y, x)
Your points get transformed to ...
(2, -5) ⇒ (5, 2)
(1, -5) ⇒ (5, 1)
(1, -2) ⇒ (2, 1)
(2, -2) ⇒ (2, 2)
