Answer:
y = 1/2x - 2
Step-by-step explanation:
Slope intercept form:
y = mx + b
x - 2y = 4
-2y = -x + 4
2y = x - 4
y = 1/2x - 2
x - 3y=-12

A rectangular field is 36
meters long and 15 meters
wide How many more meters
18 it to walk on the sidewalk
rother than cutting through
the field diagonally?
Answer:
12meters
Step-by-step explanation:
Given data
Lenght = 36 meters
Width = 15 meters
The dimension of the diagonal can be gotten via Pythagoras theorem
D^2= L^2+W^2
Substitute
D^2= 36^2+ 15^2
D^2= 1296+225
D^2= 1521
D= √1521
D= 39 meters
Hence the distance while walking on the side is
=36+15
=51 meters
Hence the difference is
=51-39
=12meters

Solve for y.
- 12 = 6y +18-9y
Answer:
[tex] \boxed{y = 10} [/tex]
Step-by-step explanation:
-12 = 6y + 18 – 9y
[Group like terms 6y and -9y]
-12 = (6y – 9y) + 18
[Simplify the expression]
-12 = -3y + 18
[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]
-12 = -3y + 18
–18 –18
-30 = -3y
[Divide by -3 from both sides, division property of equality, to get the variable y by itself]
-30 = -3y
÷(-3) ÷(-3)
10 = y
[Symmetric property of equality, if b = a, then a = b]
y = 10
Simplify by adding like terms: 2abab - 4ba^2b + 7ab^a + 3a^2b

Find the shaded area. Leave your answers in terms of PI.
Answer choices:
4π
64π
6π
8π
Answer:
8π cm^2
Step-by-step explanation:
Here's your solution
=> Area of biggest circle = πr^2
=> Area = 16π cm^2
=> Area of small circle = 4π cm^2
=> there are two circles hence both area =
8π cm^2
=> now, Area of shaded region = 16π cm^2 - 8π cm^
=> Area = 8π cm^2

Mary makes trait mix with bulk nuts and dried fruit. She spends on the dried fruit Mixed nuts cost $2.50 per pound. She has a total of $12 to spend
How many pounds of nuts can she buy?
Answer:
4 pounds
Step by Step Explaintion
The required Mary can buy 4 pounds of mixed nuts with her remaining budget.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
If Mary has a total of $12 to spend and she spends $2.50 on dried fruit, then she has $12 - $2.50 = $9.50 left to spend on mixed nuts.
If mixed nuts cost $2.50 per pound, then Mary can buy $9.50 / $2.50 per pound = 3.8 pounds of mixed nuts.
However, since Mary cannot buy a fraction of a pound, the actual amount of mixed nuts she can buy will be limited to the nearest whole number.
Therefore, Mary can buy 4 pounds of mixed nuts with her remaining budget.

Teniendo en cuenta que tg 45°=1, deduce el valor de sen 45° y de cos 45° mediante las relaciones fundamentales.
Answer:
the value is 0.707
Step-by-step explanation:
The computation is shown below:
Tan (x) = sen (x) ÷ cos (x)
Tan 45° = sen 45° ÷ cos 45° = 1
Now
Sen^2 (x) + cos^2 (x) = 1
Sen^2 (x) + sin^2 (x) = 1 (As sen (x) = u)
2u^2 = 1
u = √1 ÷ √2
= √2 ÷ 2
= 0.707
Hence, the value is 0.707

Brian and sonya each have a container. They mark their containers to show tenths. Brian and sonya both fill their containers with 0.7 units of juice. However, brian has more juice in him container. Explain how this is possible.
Answer:
Step-by-step explanation:
Brian could have more juice than Sonya in actual sense, This is because the representation used, that is the container has been calibrated to show tenth. This means that decimal values of juice in the container will not show explicit volume beyond tenth. Hence the volume will be rounded.
For instance, if the actual volume of juice Brian has Is 0.74 and that owned by Sonya is 0.69. In actual sense, 0.74 > 0.69 . However, if both pour their juice into the calibrated container, Brian's volume will be rounded to the nearest tenth as 0.7 and Sonya's (0.69) will also be rounded to 0.7.
But in actual sense, Brian has more Juice than Sonya.
Why do you think sum or difference formulas will be helpful with finding the exact
ues of uncommon angles?
Answer:
The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

Olive is allowed to bring one friend on a trip with her.
She does not want to play favorites.
What is NOT a random method of choosing a friend? what’s is NOT a random method of choosing a friend
Answer:
Process of elimination
Step-by-step explanation:
If Olive wants to choose a friend while not playing favorites, while also not being random, she has to eliminate the ones she knows she will NOT take on the trip. She can choose this by selecting the one she knows that will be best on the trip with her, depending on the situation.
Or, if Olive only has one friend, then it wouldn't be surprising that she would take that one friend on the trip, since she has no one else to choose. This way, it is not playing favorites, nor is it random. Hope this helps you!
