Answer: Length = 28 feet
Width = 4 feet
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of the rectangle is 64 feet. This means that
2(L + W) = 64
Dividing through by 2, it becomes
L + W = 32 - - - - - - - - - - - -1
The rectangle is 7 times as long as it is wide. This means that
L = 7W
Substituting L = 7W into equation 1, it becomes
7W + W = 32
8W = 32
W = 32/8
W = 4
L = 7W = 7 × 4
L = 28
Answer:
-28
Step-by-step explanation:
Simply plug -5 in for x in the given equation
f(-5) = 5(-5) - 3
f(-5) = -25 - 3
f(-5) -28
Answer:
sale price = 408
Step-by-step explanation:
480 * 15/100 = 72
sale price = 480 -72 =408 (ans)
Answer:
See example below.
Step-by-step explanation:
If the function has the table:
x f(x)
-3 -6
-2 -4
-1 -2
0 0
Step 1 : Looking at the table, find a pattern. This table f(x) deceases by 2 each time. This is a constant rate of change called slope.
Step 2: Recognize the pattern. Since it is decreasing by 2 each time, this is a linear function. Its equation can be written using y = mx+b.
Step 3: Use the form, y =mx + b and substitute m and b.
Step 4: The slope is m . The slope is -2. m = -2.
Step 5: Find the y-intercept. b is the y-intercept or starting point where x = 0. When x=0, the table shows y=0. So b=0.
This means the rule is y = -2x.
