Alex goes to a movie on Saturday for $10. While there, he pays $3 for each item he buys at the concession stand.
Which equation best represents this information?
y = 10x + 3
y = 3x - 10
y = 3x + 10
y = 10x - 3

To find the equation for a line parallel to y = 2x + 1 and passing through the point (1,5), we need to remember that parallel lines have the same slope.

Since the slope of y = 2x + 1 is 2, the slope of the parallel line will also be 2.

Using the point-slope form of a linear equation, we can plug in the given slope and point to find the equation of the parallel line:

y - y1 = m(x - x1)

y - 5 = 2(x - 1)

Simplifying this equation gives us the equation for the parallel line:

y = 2x + 3

So, the equation for the line parallel to y = 2x + 1 and passing through the point (1,5) is y = 2x + 3.

In the given figure by using the alternative angles rule we know that x = 82°.

Alternate angles are a unique type of angle in geometry.

The collection of non-adjacent angles on either side of the transversal is known as alternate angles.

Alternative Interior Angles: Angles are created on the inside, or interior, of two other lines when a third line known as the transversal crosses them. These other lines are typically parallel.

The alternate internal angles are those that are perpendicular to one another.

So, in the given figure:

∠ABD = ∠BDC = 35° (Alternate angles)

Then, ∠DBC will be:

82 + 35 + x = 180

117 + x = 180

x = 180 - 117

x = 63°

Then, ∠DBC = ∠BDA = 63° (Alternate angles)

Now, ∠DAB = 63 + 35 + x = 180

= 63 + 35 + x = 180

= 98 + x = 180

= x = 180 - 98

= x = 82°

Therefore, in the given figure by using the alternative angles rule we know that x = 82°.

The true statement about the polynomials is (b) No, it's only with polynomials with a degrees of 1

Given that the polynomials f and g have a degree of 3

The composition of two functions, f ∘ g (read as "f composed with g"), is not commutative in general, meaning that f ∘ g is not necessarily equal to g ∘ f.

This holds true for polynomials of degree 3 as well.

In fact, if f and g are two different polynomials of degree 3, then f ∘ g and g ∘ f will be different polynomials in general.

The equation f ∘ g = g ∘ f holds true is when f and g are constant polynomials, that is, polynomials of degree 0 or 1.

The final answer length of the other dimension of the garden is 9x units.

To find the length of the other dimension of the garden, we need to use the formula for the area of a rectangle:

Area = Length x Width

We are given the area and one dimension, so we can plug those values into the formula and solve for the other dimension:

[tex]81x^2-126x[/tex] = (9x-14)(Length)

To solve for the length, we need to divide both sides of the equation by (9x-14):

Length =[tex](81x^2-126x)/(9x-14)[/tex]

Now we can simplify the right side of the equation by factoring out a common factor of 9x:

Length = (9x)(9x-14)/(9x-14)

The (9x-14) terms cancel out, leaving us with:

Length = 9x

So the length of the other dimension of the garden is 9x units.

Brendan is currently 37 years old.

To solve this problem, we can use algebra. Let's let V represent Valerie's age and B represent Brendan's age. We can set up the following equations based on the information given in the question:
B = V + 5 (Brendan is 5 years older than Valerie)
B + 6 + V + 6 = 81 (In 6 years, the sum of their ages will be 81)
Simplifying the second equation, we get:
B + V + 12 = 81
B + V = 69
Substituting the first equation into the second equation, we get:
V + 5 + V = 69
2V = 64
V = 32
Now that we know Valerie's age, we can use the first equation to find Brendan's age:
B = 32 + 5
B = 37
So Brendan's current age is calculated to be 37 years

a) The purchase price of the new equipment is $20,531.76.

b) The amount of interest that will have to be paid is $6,948.24.

The purchase price of the new equipment for New Bread Bakery can be found using the formula for the present value of an annuity:

PV = PMT * [(1 - (1 + i)^(-n)) / i]

Where PV is the present value (or purchase price), PMT is the monthly payment, i is the monthly interest rate, and n is the number of payments.

Plugging in the given values:

PV = 458 * [(1 - (1 + 0.092/12)^(-5*12)) / (0.092/12)]

PV = 458 * [(1 - (1 + 0.00767)^(-60)) / 0.00767]

PV = 458 * [(1 - 0.6887) / 0.00767]

PV = 458 * 40.4624

PV = 18,531.76

The purchase price of the new equipment is $18,531.76. However, this does not include the down payment of $2000. So, the total purchase price is:

PV + Down Payment = 18,531.76 + 2000 = $20,531.76

To find the amount of interest that will have to be paid, we can subtract the purchase price from the total amount paid over the five years:

Interest = (458 * 5 * 12) - 20,531.76 = 27,480 - 20,531.76 = $6,948.24

Therefore, the amount of interest that will have to be paid is $6,948.24.

y = 3sin(πt). This function models the oscillation by representing the distance in centimeters from the equilibrium position as the sine of π multiplied by the time in seconds.

y = 3sin(πt). This function can be used to model the oscillation because it represents the distance in centimeters from the equilibrium position as the sine of π multiplied by the time in seconds. This means that for any given value of t, the value of y will be the sine of π multiplied by t, which will correspond to a certain distance from the equilibrium position. As the oscillation has a frequency of 1 cycle per second, the value of t will increase linearly, and the value of y will oscillate between a maximum and a minimum value. As the distance between the maximum and minimum points of the oscillation is 3 centimeters, the maximum and minimum values of y will be 3 when t is an integer multiple of π. Therefore, the function y = 3sin(πt) can be used to accurately model the oscillation.

The amount of time it will take them when working together is 12/7 hours, or approximately 1.71 hours.

If Harry can paint a room in 3 hours, and Kerry can paint it in 4 hours, then we can use the formula for combined work (work rate) to find how long it will take if they work together. The formula is:

1/t = 1/t₁ + 1/t₂, where t is the time it takes for them to complete the work together, t₁ is the time it takes for Harry to complete the work alone, and t₂ is the time it takes for Kerry to complete the work alone.

Plugging in the values we have, we get:

1/t = 1/3 + 1/4.

Multiplying both sides of the equation by 12t, we get:

12 = 4t + 3t.

Simplifying, we get:

12 = 7t.

Dividing both sides of the equation by 7, we get:

The answer is \(a+b+c+d = 10\).

To find \(a+b+c+d\), we can use matrix multiplication to solve for each variable. Matrix multiplication is performed by multiplying the elements of each row of the first matrix by the corresponding elements of each column of the second matrix, and then summing the products.

So, we can set up the following equations:

\(10 = 1a + 2c\)

\(1 = 1b + 2d\)

\(-6 = 3a - 3c\)

\(-6 = 3b - 3d\)

Solving for each variable, we get:

\(a = 6 - 2c\)

\(b = (1 - 2d)/1\)

\(c = (6 + 3a)/(-3)\)

\(d = (3b + 6)/(-3)\)

Substituting the values of \(a\) and \(b\) into the equations for \(c\) and \(d\), we get:

\(c = (6 + 3(6 - 2c))/(-3)\)

\(d = (3((1 - 2d)/1) + 6)/(-3)\)

Solving for \(c\) and \(d\), we get:

\(c = -2\)

\(d = -1\)

Substituting these values back into the equations for \(a\) and \(b\), we get:

\(a = 6 - 2(-2) = 10\)

\(b = (1 - 2(-1))/1 = 3\)

So, \(a+b+c+d = 10 + 3 + (-2) + (-1) = 10\).

The coordinates of point D are (-5, -10). To dilate point A, we can subtract the coordinates of D from the coordinates of A, multiply by 1.5, and then add the coordinates of D back:

D1.5(A) = 1.5[(2, 0) - (-5, -10)] + (-5, -10) = 1.5(7, 10) + (-5, -10) = (6.5, 5)

Similarly, we can dilate points B and C:

D1.5(B) = 1.5[(8, -4) - (-5, -10)] + (-5, -10) = 1.5(13, 6) + (-5, -10) = (14.5, -4)

D1.5(C) = 1.5[(4, -6) - (-5, -10)] + (-5, -10) = 1.5(9, 4) + (-5, -10) = (7.5, 4)
