Answer:
Parallel - 8
Perpendicular - -1/8
Step-by-step explanation:
If a line is parallel to another then they have the same slope
If a line is perpendicular to another line then the slope is just flipped and so is the sign
1.7/1.9 = 0.894 (rounded)
(f×g)(-1) is -14.
Step-by-step explanation:
- Step 1: Calculate (f×g)(x) by using the formula (f×g)(x) = f(x) × g(x)
⇒ (f×g)(x) = (x + 3)(4x - 3)
⇒ (f×g)(x) = 4x² - 3x + 12x - 9
⇒ (f×g)(x) = 4x² + 9x - 9
- Step 2: Find (f×g)(-1) by substituting -1 in the place of x
⇒ (f×g)(-1) = 4(-1)² + 9(-1) - 9
⇒ (f×g)(-1) = 4 - 9 - 9 =-14
Answer: 3
Step-by-step explanation:
25 x (5 - 2) ➗ 5 - 12
Applying the rule of BODMAS
- Solve task in bracket first
25 x (5 - 2) ➗ 5 - 12
= 25 x (3) ➗ 5 - 12
= 75 ➗ 5 - 12
- Solve task of division next
75 ➗ 5 - 12
= 15 - 12
= 3
Thus, the answer is 3
