Answer:
y=4x+7.75; continuous
Step-by-step explanation:
Let's get the equation first. So she needs one piece that's 7.75 inches long: that's a given.
y = 7.75
Now for each piece of yarn - and she needs 4 pieces - they will be x length. If she wanted them to be 1 inches in length, she would use 4 inches of yarn. So multiply those:
<u>y = 7.75 + 4x</u>
So is this graph discrete or continuous? Remember that continuous means no holes, not stopping, a nice line. Discrete means it has holes or gaps. (In science, we would call discrete "quantized.") In this case, x will be <u>continuous, </u>because Julie can cut any length of yarn for the 4 pieces. She need not choose an integer value. Each piece could logically be 2.5 inches, or 3.1415 inches.
Area of chalkboard = 4 feet x 6 feet = 24 square feet.
Total cost = 24 square feet x $7.21 per square foot = $173.04
Answer: $173.04
My estimation will 3.5 second. You can plug this equation to a calculator and you will find the answer yourself; 16t^2+196=0
Answer:
x = 5
Step-by-step explanation:
Given
2x - 2 + 5 = 13, that is
2x + 3 = 13 ( subtract 3 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
