False.
Step-by-step explanation:
A polygon must have straight lines.
Answer:
8 dollars
Step-by-step explanation:
First, convert the yards to decimals, 1/8 is equivalent to .125, therefore 1 1/8 yards is 1.125
Next, since we know that 1 1/8 yards of fabric is $9, we can divide 9 by 1.125 in order to find the cost of one yard of fabric
9/1.125=8, therefore your final answer is $8
Don't forget to put units if this is a test question (or practically in any case), the unit in this case is $(dollars)
Answer:
Step-by-step explanation:
2y - 3x = 8
2y = 3x + 8
y = 
x +4
It is similar to y = mx + b
Therefore m =
To check whether a line has perpendicular slope we check the product of the slopes to be -1.
The perpendicular slope is
Answer:
X = 100
Step-by-step explanation:
X + 20 over 4 = 30
1/4x + 5 = 30
-5 -5
1/4x = 25
multiply both sides by 4
x = 100
The relationship is a function. A function is an equation of graph that has no repeated x values. In this graph, each x value has a different y value, whether it's (1, 70) or (9,95)
If Rachel gets anything other than a 95, the x value of 2 will have more than one y value: 95 and whatever grade Rachel gets. Therefore it will no longer be a function.
