Answer:
Answer is B
Step-by-step explanation:
If point D with coordinates (a,b) is reflected over the line y=x then the image point D' coordinates are (b,a) (see picture for details).
The middlepoint M of segment DD' lhas coordinates and lies on the line y=x (since its coordinates are equal), DD' is perpendicular to the line y=x and DM=D'M. All these remarks show that the point D' is the image point of D.
Answer:
25 days
Step-by-step explanation:
6.50 x 8 = 52
52 ÷ 5 = 10.4
10.4 × 4 = 41.6
1040 ÷ 41.6 = 25

Answer:
D. <
Step-by-step explanation:
-17 is less than -1. Think of it as going down stairs. Who is lower? The person 17 steps down or the person 1 step down. 17 steps down.
-17 < -1
If one of our zeros is 4, then the factor is x-4. If the second zero is 5i, then the conjugate root theorem says there HAS to be a root that is -5i. So our 3 factors are (x-4)(x+5i)(x-5i). We will FOIL out these factors to get the polynomial. Let's start with the ones that contain the imaginary numbers. Doing that mutliplication we get x^2-25i^2. i^2 is equal to -1, so what that expression simplifies down to is
. Now we will multiply in that last factor of (x-4):
. FOILing out we have
. There you go!
