Answer:
180 strips
Step-by-step explanation:
Note that:
1 yard = 36 inches
5 yards = x
Cross Multiply
x = 5 × 36 inches
x = 180 inches
Hence:
1 piece of fabric = 180 inches
How many 1-inch strips can be cut from the fabric?
180 inches = 1 piece of fabric
1 inch = x
x = 180 strips
To solve for m we want to get m by itself on one side of the equals sign, with everything else on the other side. First we subtract b from both sides, to get it out of the right side of the equation:
y - b = mx + b - b
y - b = mx
Now we divide both sides by x, to get m completely by itself:
(y-b)/x = (mx)/x
(y-b)/x = m
So m is equal to (y-b)/x.
We have points (-3, 4), (-1, 2), (4, -3) and (6,-5)
Let's verify it's a line by calculating the slopes between successive points.
Slope is change in y over change in x.
(2 - 4)/(-1 - -3) = -2/2 = -1
(-3 - 2)/(4 - -1) = -5/5 = -1
(-5 - -3)/(6 - 4) = -2/2 =-1
Yup. We have a line of slope -1 through point (-1, 2)
y - 2 = -1(x - -1)
y = -x - 1 + 2
y = -x + 1
That's the linear equation for the table.
Answer: Linear equation: y = -x + 1 slope = -1
Answer:
44.2%
Step-by-step explanation:
Rate of discount = (difference in prices / original price) x 100
Difference in price = $1299 - $725 = $574
Original price = $1299
($574 / $1299) x 100 = 44.187837%
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
the hundredth figure is 8, which is greater than 5. 1 would be added to the tenth figure.
So it becomes 44.2%
-5x - 6y = -21
5x - y =. 84
-7y = 63
y= -9
-5x = -21 - 54
-5x = -75
x = 15
