Answer:
C
Step-by-step explanation:
The triangle is reflected across the y-axis and moved down 3 units.
Here is the solution of the given problem above:
Given: appliance A, B and C: 1 7/8 watts x 3 = 45/8 watts
appliance D : 4 3/4 watts
appliance E : 4 3/4 watts
?: total power used by these appliances
In order to know the total, we just have to add the number of watts.
So we add 45/8 watts plus 38/4 watts. The common denominator for these two fractions is 32. Therefore, the final answer would be 15 4/32 or 15 1/8 watts. The correct answer would be the last option. Hope this answer helps.
Answer:
2
Step-by-step explanation:
Use slope formula: (y2-y1)/(x2-x1)
(14-6)/(8-4) = 8/4 = 2
The gradient is 2
Answer:
Quotient ( x² -4x +10)
Reminder -2
Step-by-step explanation:
We have to consider the polynomial function g(x) = x³ - 3x² + 6x + 8
Now, we have to divide g(x) by (x+1)
Let us arrange the terms of g(x) to get (x+1) as common.
x³ - 3x² + 6x + 8
= x³ +x² -4x² -4x +10x +10 -2
= x² (x +1) -4x (x +1) +10 (x +1) -2
= (x +1)( x² -4x +10) -2
Hence, if we divide g(x) by (x +1) then the quotient will be ( x² -4x +10) and the reminder will be -2. (Answer)
