Answer:
first spot 10, second 16, third 18, fourth 22
Answer:
The expression that represents the table is
y=4+2x
when x=3
y=4+2(3) = 10
When x=6
y=4+2(6)= 16.
Do this for all the values of x and you'll get the corresponding value for y

Your answer would be
the sum of two positive numbers is 588. minimize the sum of the first and three times the second
9514 1404 393
Answer:
{587, 1}
Step-by-step explanation:
The sum will be minimized when the second number is as close to zero as is allowed. If the numbers must be positive integers, the sum is minimized when the numbers are {587, 1}.
If the numbers may be real numbers, then the values that minimize the sum are {588-, 0+}
_____
The "cost" of taking a unit from the sum 588 and assigning it to the second number is that the sum of first and 3 times the second goes up by 3. In order to minimize that sum, the second number must be minimized.
f(x) = - 2x - 3
g(x) = 3x + 1
Find (f .g)(x).
Answer:
-6x² - 11x - 3
Step-by-step explanation:
This represents the product of the two functions.
(-2x-3)(3x+1) = -(2x+3)(3x+1) = -(6x² + 11x + 3) = -6x² - 11x - 3
The sales tax for an item was $21.70 and it cost $310 before tax.
Find the sales tax rate. Write your answer as a percentage.
Answer:
[tex]Sales \ Tax \ Amount = Net \ Price \cdot \frac{Sales \ Tax \ percentage}{100}[/tex]
[tex]21.70 = 331.70 \cdot \frac{sales\ tax \ percentage}{100} \\\\\frac{21.70}{331.70} = \frac{sales\ tax \ percentage}{100}\\\\0.0654 = \frac{sales\ tax \ percentage}{100}[/tex]
Sales Tax Percentage = 0.0654 × 100 = 6.54%

Cookies were $1 and Brownies were $2. You spent
$13 total.
What are three combinations of cookies and brownies
that you could have gotten?
Write an equation that represents this situation.
Answer:
If cookies are for $1 and brownies are for $2, let number of cookies = x and number of brownies = y
∴ $1*(x*1) + $2*(y*1) = $13
Step-by-step explanation:
1) You can buy 4 brownies for $2 each = 2*4 = $8
The rest you can buy cookies = 5 cookies = $5
$8+$5=$13
2) You can buy 5 brownies and 3 cookies = $10+$3 = $13
3) You can buy 3 brownies and 7 cookies = $6+$7=$13
Equation: -
If cookies are for $1 and brownies are for $2, let number of cookies = x and number of brownies = y
∴ $1*(x*1) + $2*(y*1) = $13
what is the value of x ?
please help me!!!
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Find the base of a triangle with an area of 45 square yards and a height of 20 yards.
Answer:
Base, b = 4.5 yards
Step-by-step explanation:
Given the following data;
Area of triangle = 45 square yards
Height = 20 yards
To find the base of the triangle;
Mathematically, the area of a triangle is given by the formula;
Area of triangle = ½ * b * h
Where;
b is the base of the triangle.
h is the height of the triangle.
45 = ½ * b * 20
90 = 20b
Base, b = 90/20
Base, b = 4.5 yards

[tex]\frac{1}{14}[/tex] is half of [tex]\frac{1}{7}[/tex]
This would be true because half of a number can be found by multiplying by [tex]\frac{1}{2}[/tex]
If you multiplied [tex]\frac{1}{7} * \frac{1}{2}[/tex]
The numerator is 1 * 1 which is 1
And then the denominator is 7 * 2 which is 14
That would give you [tex]\frac{1}{14}[/tex]

The products of two reciprocals is 0
This is not true
Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.
Ex: [tex]\frac{2}{8}[/tex]
Its reciprocal is [tex]\frac{8}{2}[/tex]
So multiply them together
[tex]\frac{2}{8}* \frac{8}{2}[/tex]
2 * 8 = 16
8 * 2 = 16
[tex]\frac{16}{16} = 1[/tex]
i.
A whole number does not have a reciprocal
This is incorrect. If you think about it, a whole number is just the number, over 1
Ex: [tex]\frac{6}{1}[/tex]
This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.
If you an write it as a fraction, it has a reciprocal.
The reciprocal in this case would be [tex]\frac{1}{6}[/tex]
