Answer: (c) y<=-x+4
The area is shaded UNDER the boundary line, hence "<"
The boundary is plotted as solid line, hence "="
Answer: 29, 30, 35, 36
Step-by-step explanation:
As per your info about first page.
The paper containing 64 has following other pages
On the back of 29, it is 30. The pages are such that for each page p, 65-p will be also on the same page.
Then,
65-29= 36
65-30 = 35
So the four pages in this sheet are 29, 30, 35, 36.
Well,
we know that we need to accumulate points from x and y to reach 20 points.
since x provide 3 and y provide 4 points, the formula would be :
3x + 4y = 20
or it can be written as :
y = (3x/4)+5
hope this helps
direct variation
y = kx
substitute in and solve for k
14 = k(-4)
14/-4 =k
k = -7/2
y = -7/2 x
y = -7/2 * -6
y = 42/2 = 21
