Answer:
-50k+27
Step-by-step explanation:
=(−5)(1)+(−5)(2k)+(−8)(−4)+(−8)(5k)
=−5+−10k+32+−40k
Combine Like Terms:
=−5+−10k+32+−40k
=(−10k+−40k)+(−5+32)
=−50k+27
Answer:
X1 = 8,472
X2 = - 0,472
Step-by-step explanation:
I did f(x) = g(x) and then I took it all to one side so it would look like x2-8x-4=0
Then I use the p-q-formulann.
Find the area of the rectangle (bh) and then the area of half of the circle (pi times r (squared)) then divide it by two and subtract the half circle area from the rectangle area
18/5. Multiply the 5 as many times as you need to to get to 25. Then as many times as you multiplied the bottom multiply the top the same so it would be 5 times on both sides making the ratio. 90/25
Answer:
(-13,6)
Step-by-step explanation:
Rule for rotation 90 degrees clockwise around the origin
( x , y ) --------> ( y , -x )
Explanation of rule:
Swap the x and y values
Change sign of new y value
Find Q' after a rotation 90 degrees clockwise around the origin
Given coordinates of Q
(-6,-13)
Apply rotation 90 degree clockwise rule
(-6,-13) -------> swap x and y values -------- -> (-13,-6) -------> change sign of new y value --------> (-13,6)
Q' will be at (-13,6) after a rotation 90 degrees clockwise around the origin
