Answer: The change in temperature each hour was 6 degrees celsius.
Step-by-step explanation: 48 divided by 8 = 6
Answer:
I. L = 17 cm.
II. W = 11 cm.
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Perimeter of rectangle = 56cm
Translating the word problem into an algebraic expression, we have;
L = W + 6 .....equation 1
The perimeter of a rectangle is given by the formula;
P = 2(L + W)
56 = 2(L + W) ......equation 2
Substituting eqn 1 into eqn 2, we have;
56 = 2(W + 6 + W)
56 = 2(6 + 2W)
Opening the bracket, we have;
56 = 12 + 4W
4W = 56 - 12
4W = 44
W = 44/4
W = 11 cm
Next, we would find the length of the rectangle;
From eqn 1;
L = W + 6
L = 11 + 6
L = 17 cm
X would equal 1 in this problem since 1+2=3 and the absolute value(s) in this equation would be -1+(-2)=3 since, a negative plus a negative equals a positive.
I hope this helped you!
Answer: 16 books
Step-by-step explanation:
40(.15)=6
40-6=34
34-14=20
20-4=16
Trial and error
y=-4x+4
or assuming that it is a line
y=mx+b
m=slope
b=yint
slope=(y2-y1)/(x2-x1)
(0,4) and (1,0)
(0-4)/(1-0)=-4/1=-4
y=-4x+b
sub point
4=-4(0)+b
4=0+b
4=b
y=-4x+4
