Answer:
- 5 + 4a
Step-by-step explanation:
- 6 + 2a + 1 + 2a
- 6 + 1 + 4a
- 5 + 4a
Are u trying to find the volume? Or surface area or area?
Step-by-step explanation:
distance = -6-(-2) and 4-2
-6+2 and 2
-4 and 2 is distance
Answer:
- 1. C, 2. B, 3. A, 4. C, 5. A, 6. - 7. C, 8. A, 9. (3, 13)
Step-by-step explanation:
<h3>Question 1</h3>
- 4p + 7 = 3 + 4 + 4p
- 4p + 7 = 4p + 7
Both sides are equal, so any value of p makes it right. It means there are infinitely many solutions
<h3>Question 2</h3>
2(3x − 4) = 8 + 2x + 4
Step 2 was wrong, it should be 6x - 8 = 12 + 2x
<h3>Question 3</h3>
- 3/(4z) - 1/(4z) + 3 = 2/(4z) + 5
- 2/(4z) + 3 = 2/(4z) + 5
- 3 = 5
It ends up with false equation, so no solution.
<h3>Question 4</h3>
- 1.6m − 4.8 = −1.6m
- 1.6m + 1.6m = 4.8
- 3.2m = 4.8
- m = 4.8/3.2
- m = 1.5
<h3>Question 5</h3>
Line C: y = x + 14
Line D: y = 3x + 2
- x+ 14 = 3x + 2
- 3x - x = 14 - 2
- 2x = 12
- x = 6
Solution is (6, 20), this is the intersection of lines
<h3>Question 6</h3>
- It should have a graph attached, so ignored
<h3>Question 7</h3>
- b - 2 - 3b = 16 ⇒ -2b = 18 ⇒ b = - 9
Solution is (a, b) = (- 11, - 9)
<h3>Question 8</h3>
Easy method is substitution: w + 2 = 7w - 16
<h3>Question 8</h3>
<u>Easy method is substitution:</u>
- 7x - 8 = 5x - 2
- 7x - 5x = 8 - 2
- 2x = 6
- x = 3
- y = 7*3 - 8 = 21 - 8 = 13
- The point (3, 13) is the solution and it is the intersection of the lines.
