1) : 2x + 5y = 12 a. (1,?) b. (?, 1) C. (0,?) d. (?, 0)
Answers
Answer:
A. y = 2
B. x = 7/2
C. y = 12/5
D. x = 6
Step-by-step explanation:
A. Determination of y .
2x + 5y = 12
x = 1
2(1) + 5y = 12
2 + 5y = 12
Collect like terms
5y = 12 – 2
5y = 10
Divide both side by 5
y = 10 / 5
y = 2
B. Determination of x
2x + 5y = 12
y = 1
2x + 5(1) = 12
2x + 5 = 12
Collect like terms
2x = 12 – 5
2x = 7
Divide both side by 2
x = 7/2
C. Determination of y
2x + 5y = 12
x = 0
2(0) + 5y = 12
0 + 5y = 12
5y = 12
Divide both side by 5
y = 12/5
D. Determination of x
2x + 5y = 12
y = 0
2x + 5(0) = 12
2x + 0 = 12
2x = 12
Divide both side by 2
x = 12/2
x = 6

Given the following number as an approximate measurement, 49.5 feet. What is the range of values for the actual value?
Answers
Answer:
range is 2
Step-by-step explanation:
The range of values for the actual value is 2.
A range is the simplest measurement of the difference between the values in a dataset. To find the range, subtract the minimum value from the maximum value and ignore the other values. Where the minimum is 155 and the maximum is 720.
The statistical range for a particular dataset is the difference between the maximum and minimum values. For example, if the specified record is {2,5,8,10,3}, the range is 10 – 2 = 8. Therefore, the range can also be defined as the difference between the highest and lowest observations.

The circumference is given by ...
C = πd
C = (3.14)(4 ft) = 12.56 ft
Adding the 24 ft of straight sections, we find the total perimeter to be ...

Answer:
145
Step-by-step explanation:
Each triangular side is 30ft
bottom is a 5*5 so it 25ft
30*4(#of sides)=120
120+25(bottom)=145
Answer:
I will give you the easy explanation here, go down there though to get a more complexed explanation and answer. Seeing it is a triangle, you can not multiply the 12 by 5. You have to multiply it by 2.5 because it dips in (because it's a triangle). Now you multiply the 5x5 to get 25. Now we have 25 for the base and 30 for each side. 30x4 to represent each side and add 25 for the base to get 145 as the final answer.
Step-by-step explanation:
Ok, they made this really easy with the 5's. You multiply the 5 by the 5 to get 25 in which the 12 there is about half of that, that made things really easy. Since the 12 goes to the middle that means that we can take what is from the middle to the side removing the half there getting you -2. Therefore, 12-2=10. Meaning the center is 10.

Step-by-step explanation:
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
Let (-1, 5) be (x₁, y₁) and our slope m is -7. By substitution:
[tex]y-(5)=-7(x-(-1))[/tex]
