20 = 8x + 4y
what is y?
Answer:
y = -2x + 5
Step-by-step explanation:
20 = 8x + 4y
subtract 8x from both sides
4y = -8x + 20
divide both sides by 4
y = -2x + 5
The value of y is 5-2x=y
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 20 = 8x + 4y
Twenty equal to eight times of x plus four times of y.
We need to solve the equation for y.
To solve this we need to separate the variable y.
Subtract 8x on both sides
20-8x=4y
Divide both sides by 4
20/4-8/4x=y
5-2x=y
Hence, the value of y is 5-2x=y

An airplane lands on a runway with a velocity of 150 m/s. How far will it travel until it stops if its rate of
deceleration is constant -3m/s2?
Answer:
3750 m
Step-by-step explanation:
This question can be solved using law of equation of motion
[tex]v^2 = u^2 + 2as[/tex]
where v is the final velocity
u is the initial velocity
a is the acceleration
and
s is the distance travelled
________________________________
given
final velocity = v = 0 since it is given that plane stops
u = 150 m/s
a = -3m/s2
using the above values in the given equation
[tex]v^2 = u^2 + 2as\\0 = 150*2 + 2*-3s\\0 = 22500 - 6s\\=> 6s = 22500\\=> s = 22500/6 = 3750[/tex]
Thus, plane will travel 3750 m before it stops.

Answer:
(a) 259.5 days
(b) 284 days
Step-by-step explanation:
Let X represent the pregnancy length in days.
It is provided that [tex]X\sim N(270,9^{2})[/tex].
(a)
Let a represent the minimum pregnancy length that can be in the top 12% of pregnancy lengths.
Then,
P (X < a) = 0.12
⇒ P (Z < z) = 0.12
The corresponding z-score is, z = -1.17.
*Use a z-table.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\-1.17=\frac{a-270}{9}\\\\z=270-(9\times 1.17)\\\\z=259.47\\\\z\approx 259.5[/tex]
Thus, the minimum pregnancy length that can be in the top 12% of pregnancy lengths is 259.5 days.
(b)
Let b be the maximum pregnancy length that can be in the bottom 6% of pregnancy lengths.
Then,
P (X > b) = 0.06
⇒ P (X < b) = 0.94
⇒ P (Z < z) = 0.94
The corresponding z-score is, z = 1.56.
*Use a z-table.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\1.56=\frac{b-270}{9}\\\\z=270+(9\times 1.56)\\\\z=284.04\\\\z\approx 284[/tex]
Thus, the maximum pregnancy length that can be in the bottom 6% of pregnancy lengths is 284 days.
Mr. Jones bought a car for $64 000. The car depreciates by 20% in the first year and 10% in each of the following years. The value of the car at the end of the second year was *
Depreciation for 1st year = 20/100 × 64000 = $12800
End of 1st year = $64000 - $12800 = $51200
Depreciation for 2nd year = 10/100 × 51200 = $5120
End of 2nd year = $51200 - $5120 = $46080
Answer:
Value at the end of the 2nd year is $46,080
Answer:
Value at the end of the 2nd year is $46,080
Step-by-step explanation:
Depreciation for 1st year = 20/100 × 64000 = $12800
End of 1st year = $64000 - $12800 = $51200
Depreciation for 2nd year = 10/100 × 51200 = $5120
End of 2nd year = $51200 - $5120 = $46080

Vannorman Corporation processes sugar beets in batches. A batch of sugar beets costs $78 to buy from farmers and $18 to crush in the company's plant. Two intermediate products, beet fiber and beet juice, emerge from the crushing process. The beet fiber can be sold as is for $25 or processed further for $16 to make the end product industrial fiber that is sold for $57. The beet juice can be sold as is for $39 or processed further for $22 to make the end product refined sugar that is sold for $84. How much profit (loss) does the company make by processing one batch of sugar beets into the end products industrial fiber and refined sugar?
Answer:
Results are below.
Step-by-step explanation:
We will take into account the differential costs only. Therefore, the costs of sugar beets and to crush them are irrelevant to decision making.
Beet fiber:
Sold as is= $25
Continue processing= 57 - 16= $41
It is more convenient to process further the beet fiber.
Beet juice:
Sold as is= $39
Continue processing= 84 - 22= $62
It is more convenient to process further the beet juice.
There are 6 triangles and 3 circles. What is the simplest ratio of circles to
triangles?
Answer:
1 : 2
Step-by-step explanation:
The original ratio would be 3 : 6, so now you need to simplify it.
To simplify ratios, you divide the number on each side by their greatest common factor. The GCF(greatest common factor) for 3 and 6 would be 3, so divide 3 by 3 =1 and divide 6 by 3 =2, so then your simplified ratio of circles to triangles would be 1 : 2

AA and BB are n×nn×n matrices. Check the true statements below: A. If two row interchanges are made in sucession, then the determinant of the new matrix is equal to the determinant of the original matrix. B. The determinant of AA is the product of the diagonal entries in AA. C. detAT=(−1)detAdetAT=(−1)detA. D. If detAdetA is zero, then two rows or two columns are the same, or a row or a column is zero.
Answer:
If two row interchanges are made in succession, then the determinant of the new matrix is equal to the determinant of the original matrix. ( A )
Step-by-step explanation:
A and B been n*n matrices the true statement would be ; If two row interchanges are made in succession, then the determinant of the new matrix is equal to the determinant of the original matrix.
Although other options can be true for some matrices but they are not always true for every kind matrices but option A is always true

The expression shown can be used to calculate the amount of money in dollars a grocery store customer should receive in change when paying with $50. 50 − ( 14 + 12 + 2 ( 5 ) + 2 ( 2 ) + 3 ) What amount of change in dollars should the customer receive?
Answer:
The change received by the customer is $7.
Step-by-step explanation:
First, write the given expression for the change when paying with $50.
[tex]50 - ( 14 + 12 + 2 ( 5 ) + 2 ( 2 ) + 3 )[/tex]
Evaluate the parentheses:
[tex]50-(26+10+4+3)[/tex]
Now add the numbers inside the parentheses.
[tex]50-43[/tex]
Subtract the numbers.
[tex]7[/tex]
Hence, the change received by the customer is $7.

The total cost of the trip can be found by adding these components: Entrance fee per student: $5(29) Lunch costs: $4(29 + 6) Bus fees: $25 + 8($2 + $3) Total cost: 5(29) + 4(35) + 25 + 8(5) Which of these are equivalent expressions of the total cost that use the properties of operations to simplify the math? 5(15 + 14) + 4(31 + 4) + 25 + 40 5(20 + 9) + 4(30 +5) + 25 + 40 5(17 + 12) + 4(33 + 2) + 25 + 40 5(19 + 10) + 4(34 + 1) + 25 + 40
Given:
Entrance fee per student: $5(29)
Lunch costs: $4(29 + 6)
Bus fees: $25 + 8($2 + $3)
Total cost: 5(29) + 4(35) + 25 + 8(5)
To find:
The equivalent expressions of the total cost that use the properties of operations to simplify the math.
Solution:
We have,
Total cost = 5(29) + 4(35) + 25 + 8(5)
To simply this expression, we need to write 29 and 35 in the expand form or as the sum of their place values because it is easy to multiply a number with multiply of 10 and single digit.
Total cost = 5(20+9) + 4(30+5) + 25 + 40
Therefore, the correct option is B.

Answer:
X= 124
Step-by-step explanation:
Because these angles are alternate interior angles we know that X+56 will equal 180, so to solve:
180 - 56= 124
Answer:
124 degrees
Step-by-step explanation:
180 degrees is a straight line
the given angle is 56 degrees
so, all you do is subtract
180 - 56 = 124
to double check,
56 + 124 = 180
