Answer:
To determine which equation has a maximum at y =5, you will need to compare their graphs looking only at the x-values between 0 and 27.
Step-by-step explanation:
<u>x = 8</u>
<u>y = 3</u>
x = 5y - 7
x + y + 1 = 12
Because we have a value for x, we can use it in the second equation to find the value of y.
5y - 7 + y + 1 = 12
<em><u>Combine like terms</u></em>
6y - 6 = 12
<em><u>Add 6 to both sides.</u></em>
6y = 18
<em><u>Divide both sides by 6.</u></em>
y = 3
Now that we have a value for y we can place it back in the equation to find the value of x.
x + 3 + 1 = 12
<em><u>Subtract 4 from both sides.</u></em>
x = 8
C. 4(20+3)
Would be the correct answer
Answer:
first one is rational, second is also rational, third is rational, fourth is rational, and fifth is irrational.
Step-by-step explanation:
Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. The reason why is an irrational number is bc it's not a perfect square while equals to 7 and is a perfect square.
Hello! I can help you with this!
A. Okay. So, to find the area of the square all you have to do is the number square, or multiply the number by itself, in this case. 3.5. 3.5^2 is 12.25. The area of the square is 12.25 square meters large.
B. To find the area of the circle, you do pi*r^2. Radius is half the the diameter. Half of 4 is 2. 2^2 is 4. To multiply by pi, we can just do it as 3.14. 4 * 3.14 is 12.56. The circle is 12.56 square meters large.
C. The circle garden would give her the most space to plant, because 12.56 is larger than 12.25 by 0.31. The circle garden 0.31 square meters larger than the square garden.
