step 2 - 2:4×60=240
Answer:
(–3, –4)
Step-by-step explanation:
Given pair of linear equation
-4x+y = 8
=> y = 8 + 4x _____(1)
x - 5y = 17 (2)
substituting value of y from equation 1 in equation 2 we have
x - 5(8 + 4x) = 17
=> x - 5*8 -5*4x = 17
=> x - 40 - 20x = 17
=> -40 - 19x = 17
=> -19x = 17+40 = 57
=> x = 57/-19 = -3
Thus, x = -3
y = 8 + 4x = 8 +4(-3) = 8 -12 = -4
Thus, y = -4
Hence, paired solution for given equation is (–3, –4).
Answer:
the width is ≤ 38 feet
Step-by-step explanation:
the perimeter of a rectangle is given by the relation : 2*( length + width)
P ≤ 120
2 (L + W) ≤ 120
L + W ≤ 60 ,,, L = 22
22 + W ≤ 60
W ≤ 38 feet
Answer:
(b^2 + 8b - 9) - (11b^2 + 4b -7)
