10 y + 4 = 0
A) x - y=0
C) -y=-4
B) y=-4
D) x + y = 0

Answers

Answer 1

Answer:

B) y = -4

Step-by-step explanation:

When rearranging an equation we divide, multiply, subsract, add the same things to both sides of the equation.

So here we would - 4 from both sides to give:

y + 4 - 4 = 0 - 4

This would simplify to:

y = -4

Step-by-step explanation:

9x5

=45

Answer:

45

Step-by-step explanation:

To be divisible by five, the number must end with a zero or a five, and forty-five is the only number that meets these conditions. Technically, all the numbers are divisible by five, but 83, 94, and 99 divided by five would equal a whole number with a decimal, meaning the only option that equals a whole number is forty-five (45).

Answers

Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

It is given that

Addison has a balance of $3,450 on her credit card.

APR = 18%

Current monthly payment = $86.25

She wants to choose a monthly payment for 24 months.

So for 24 months,

A revised monthly payment using the formula,

[tex]M = \frac{P.\frac{R}{12}. (1+\frac{R}{12} )^N }{(1+\frac{R}{12})N -1}[/tex]

R = 0.18

P = 3450

N = 24

Revised montly payment M = $172.24

Current monthly payment = $86.25

Difference = $86

So, she needs to cut the expenses by  $86

If she cut $45 from Food/Clothes and $41 from Entertainment, she can easily pay the revised monthly payment.

Therefore, Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

which we already proven in another question, while for idenity (b)

[tex](A)\frac 1 {sin x} -sin x = cos x \frac{cos x}{sin x}\\\\(B)\frac {1-sin^2x}{sin x} = \frac {cos^2x} {sin x} \\\\(C) \frac {cos^2x}{sin x} =\frac {cos^2x} {sin x}[/tex]

One rectangle is "framed" within another. Find the area of the shaded region if the
"frame" is 2 units wide.
10
7

Answers

The area of the shaded rectangle is 18 square units.

How to get the area of the shaded region?

The shaded region is the framed rectangle, and the white part is the frame.

We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:

width = 7 unitslength = 10 units

Now, if we remove the frame, we will remove 2*2 units = 4 units for each measure (because for each measure we have the frame in both sides).

So the measures for the shaded rectangle are:

width = 7 units - 4 units = 3 unitslength = 10 units - 4 units = 6 units.

And the area of a rectangle is given by the product between the width and length, then we have:

A = (3 units)*(6 units) = 18 square units.

Answer:

In total, Esme will need to purchase at minimum TWELVE (12) pieces of fence in order to encompass her entire rectangular garden.

Step-by-step explanation:

Let us start off by isolating each of the two different length sides, and figure out which fence pieces can be used to it off.

For the three meter (3 m) side, we could utilize the following THREE (3) pieces...

ONE (1) piece of 1.8 m length fenceTWO (2) pieces of 0.6 m length fence

Adding up those pieces provides us with our desired garden side length...

(1 × 1.8 m) + (2 × 0.6 m) = 3.0 m!

For the six meter (6 m) side, we could utilize the following THREE (3) pieces...

ONE (1) piece of 1.8 m length fenceTWO (2) pieces of 2.1 m length fence

Adding up those pieces provides us with our desired garden side length...

(1 × 1.8 m) + (2 × 2.1 m) = 6.0 m!

We ought to not forget about the opposite sides of the aforementioned, to make up the four sides of the rectangle! In short, we double the number of pieces that we currently have...

In the end, the smallest number of pieces of fence that Esme will need to buy is TWELVE (12), consisting of the following pieces:

TWO (2) pieces of 0.6 m length fence TWO (2) pieces of 1.8 m length fenceTWO (2) pieces of 2.1 m length fence

Marcus is buying a plane ticket. If he purchases his ticket on the day of his departure, it will cost $239. The ticket costs less if he buys it earlier. If he purchases it 20 days before his departure, it will cost $189. Model this situation by using a linear function. Then determine the cost of the ticket if Marcus buys it 3 days before his departure.

Answers

The modelled situation in a linear format is y = [tex]-\frac{5}{2}x+239[/tex]

The cost of the ticket if Marcus buys it 3 days before his departure is $231.5

Linear equation

y = mx + b

where

m = slope

b = y-intercept

b = 239

Therefore, let's model the situation to a linear equation.

y = mx + 239

using (20, 189)

189 = 20m + 239

189 - 239 = 20m

-50 = 20m

m = [tex]-\frac{5}{2}[/tex]

Therefore,

y = [tex]-\frac{5}{2}x +239[/tex]

where

x = The day before departure

y = cost of ticket

To determine the cost of the ticket if Marcus buys it 3 days before his departure.

y = [tex]-\frac{5}{2}(3)+239[/tex]

y = -7.5 + 239

y = $231.5

The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).

Let's represent the number of large oranges as "L" and the number of small oranges as "S."

From the given information, we have the following conditions:

At least three but fewer than nine large oranges: 3 ≤ L < 9

Fewer than six small oranges: S < 6

The maximum number of oranges she needs to buy is 10: L + S ≤ 10

Now, let's consider the possible combinations of L and S that satisfy these conditions:

L = 3, S = 0 (Total oranges = 3)

L = 4, S = 0 (Total oranges = 4)

L = 5, S = 0 (Total oranges = 5)

L = 6, S = 0 (Total oranges = 6)

L = 7, S = 0 (Total oranges = 7)

L = 8, S = 0 (Total oranges = 8)

L = 3, S = 1 (Total oranges = 4)

L = 4, S = 1 (Total oranges = 5)

L = 5, S = 1 (Total oranges = 6)

L = 3, S = 2 (Total oranges = 5)

L = 4, S = 2 (Total oranges = 6)

L = 3, S = 3 (Total oranges = 6)

As you can see, these are all the possible combinations of L and S that satisfy the given conditions. The girl can buy a minimum of 3 oranges (either 3 large or 3 small) and a maximum of 10 oranges (a combination of large and small).
