Answer:
(7, - 7 )
Step-by-step explanation:
- 4x + y = - 35 → (1)
- 2x - y = - 7 → (2)
adding the 2 equations term by term will eliminate the y- term
(- 4x - 2x) + (y - y) = - 35 - 7
- 6x + 0 = - 42
- 6x = - 42 ( divide both sides by - 6 )
x = 7
substitute x = 7 into either of the 2 equations and solve for y
substituting into (1)
- 4(7) + y = - 35
- 28 + y = - 35 ( add 28 to both sides )
y = - 7
solution is (7, - 7 )
Answer:
C
Step-by-step explanation:
the angle will always stay the same, it won't change
but if the dialation is 1/2, then that means that the sides will decrease in size compared to the original length,
(just divide by 2) on each side length to get the answer
I think C is the correct awnser
The correct answer would be more than 2,000 (approximately 2,205) because on the first he did 30, the second was 33, third was 36, and so on. You would have to make a chart for this, which could be somewhat boring, or you could write it out and do 30+30+3+30+6+30+9, etc for 30 different days, with 30 being for each day and progressively adding 3. Hope this helped!
