Step-by-step explanation:
Answer:
21
Step-by-step explanation:
Angle K= 90 degrees so you substitute each number for x until you get 90 and 4(21)+6=90.
Step-by-step explanation:
point-slope form means
y - y1 = m(x - x1)
(x1, y1) is a point on the function line (like the given (1, 4)).
m is the slope, weiss is the ratio of "y coordinate change / x circumstances change" when going from one point to another in the function line.
so, we need a second point. I suggest x = 0 (side length is 0), which makes also the perimeter 0 (4×0 = 0) : (0, 0)
then we see
x changes by +1 (from 0 to 1)
y changes by +4 (from 0 to 4)
the slope m is then +4/+1 = 4
and using the given point this makes the point-slope form
y - 4 = 4(x - 1)
She will need 2 packets of balloons and 1 packet of pinwheels. She will have 30 balloons and 30 pinwheels, together she will have 60 items
I think the answer would be 42/1
