Answer:
Answer is 21
Step-by-step explanation:
if you multiply 5 x 4=20 and + 1 is 21
Hi there!
6. x² + 6x = 27
subtract 27 on both sides to make the equation equal to 0.
x² + 6x - 27 = 0
(x - 3)(x + 9) = 0
x - 3 = 0 x + 9 = 0
x = 3 x = -9
7. k² - 13k + 36 = 0
(k - 9)(k - 4) = 0
k - 9 = 0 k - 4 = 0
k = 9 k = 4
8. g(x) is translated up 5 from f(x).
9. g(x) is reflected by x-axis, then translated 3 down from f(x).
Hope this helped! :)

Answer:
(3, 2)
Step-by-step explanation:
Reflection across y=x swaps the coordinates:
(x, y) ⇒ (y, x)
Dilation by a factor of 1/2 multiplies each coordinate by 1/2.
(x, y) ⇒ (x/2, y/2)
The combination of these transformations gives you ...
(x, y) ⇒ (y/2, x/2)
(4, 6) ⇒ (3, 2)
Answer:
(1, -1/2)
Step-by-step explanation:
7x - 2y = 8
5x + 2y = 4
I would use elimination to get rid of y
Add the two equations together
7x - 2y = 8
5x + 2y = 4
-------------------------
12x = 12
Divide each side by 12
x =1
Now find y
5x+2y = 4
5*1 +2y =4
Subtract 5 from each side
5+2y -5 = 4-5
2y = -1
Divide by 2
2y/2 =-1/2
y = -1/2
Answer:
the answer is 124.52
Cut it into 3 shapes, the bottom half circle, the top rectangle, and the middle rectangle
top rectangle:
A= bh
A= 4x10
A=40
middle rectangle:
A=bh
A=4x7
A= 28
Half circle:
A= πxr^2
A=πx6x6
A=πx36
A=56.52
Add it all up and you get the answer above
Plz review and thank :)
