Answer:
A) 8m-10n
B) 19r - 19s
C) 12 - 28g + 8f
Step-by-step explanation:
To write the equation in standard form:
- Distribute into any parenthesis
- Combine the like terms
- Write in descending order
A). 4 (8m-7n) +6 (3n-4m)
32m - 28n + 18n -24m
8m -10n
B). 9 (r-s) + 5 (2r-2s)
9r-9s+10r-10s
19r-19s
C). 12 (1-3g)+8 (g+f)
12 - 36g + 8g + 8f
12 - 28g + 8f
Answer:
(7, 10)
Step-by-step explanation:
The vector has an x component of 5 and a y component of 7, so we can add each of these components to the coordinates of B to get its image:
B(2,3)
B'(2 + 5, 3 + 7) = B'(7, 10)
Answer:
How long do have to finish this?
Step-by-step explanation:
-2√20 - √125
(first make radical into simplest form - make sure to get similar radical)
√20 = 4√5
√125 = 5√5
(subtract the common radicals together)
-4√5 - 5√5 = -9√5
-9√5 is your answer
