Answer:

3. y = -5x

Step-by-step explanation:

In a direct variation equation, the constant of proportionality (k) is a direct coefficient of the variable x.

Y will be set equal to x multiplied by this coefficient.

Since y = -5x directly relates x to y, with the constant of proportionality, it is a direct variation equation.

So, 3. y = -5x is the correct answer.

Answer:

vertical opposite angles are always equal

= 143°

co-interior angles are supplementary ( 180° )

∴ x = 180 - 143 = 37

∴ x = 37°

hope this answer helps you.....

Answer:

Table W represents a function

Step-by-step explanation:

Mathematically, for us to have a function , no two y-values can take a single x value

But it is possible that two x-values have a single y value

So let us make a selection from the table

We have the correct option as;

W

Answer:

Angle 5 = 37°

Angle 8 = 143°

Step-by-step explanation:

Angle 2 = Angle 8

Reason : Alternate exterior angles are equal.

Therefore,

Angle 8 = 143°

Angle 5 + Angle 8 = 180°

Reason : Angle 5 & 8 are in a linear pair.

Angle 5 + 143° = 180°

Angle 5 = ( 180 - 143 )°

Angle 5 = 37°

Answer:

the hotel charge in the first city is $5250 while the hotel charge in the second city is $3750

Step-by-step explanation:

Let a represent the charge in the first city before tax and b represent the charge in the second city before tax.

Therefore tax in first city = 10% of a = 0.1a

Tax in second city = 8% of b = 0.08b

From the total tax as $825, hence:

0.1a + 0.08b = 825           (1)

The hotel charge before tax in the second city was $1500 lower than in the first. This gives the equation:

b = a - 1500

a - b = 1500                    (2)

To find a and b, solve equation 1 and 2 simultaneously. Multiply equation 2 by 0.1 and subtract from equation 1:

0.18b = 675

b = $3750

a = b + 1500 = 3750 + 1500 = 5250

a = $5250

Therefore, the hotel charge in the first city is $5250 while the hotel charge in the second city is $3750

Answer:

Step-by-step explanation:

Answer:

v = 9 m

Step-by-step explanation:

the formula for the perimeter is P = 2W + 2L.

Here the perimeter is 42 m = 2(12 m) + 2v.  Solving for 2v, we get:

42 m - 24 m = 2v, or

v = 21 m - 12 m, or

v = 9 m

Answer:

42

Step-by-step explanation:

Since the scale factor is , we know that the bigger shape went to the smaller shape.

If we know that the smaller shape's side, 12, is  of the bigger one, we can make the equation

.

To solve for x, we can divide both sides by  .

We can multiply by the reciprocal:

Answer:

60º

Step-by-step explanation:

A triangle is 180º so you do (180-60)/2 and you get that x=60.

Hope that helps :)

Answer:

Hey love! x = 60

Step-by-step explanation:

Because a triangle adds up to 180 so

180 - 60 = 120 and sense both angles will be the same measure I divide 120 by 2 and get 60 so

x =60 Hope that helps!

Answer:

The answer would be letter J

The inequality for total expenditure & number of breakfasts is 5 > 1.25b

Assumed : Number of breakfasts = b

Number of breakfast meals x Price per breakfast meal = Total Expenditure

Total expenditure should be less or than equal to $1.25

So, 1.25b < 5

It implies that inequality : 5 > 1.25b

Answer:

23.4

Step-by-step explanation:

The area of the triangle is 23.55 in².

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

ΔWXY

w = 6.7 inches

x = 7.4 inches

∠Y = 71°

Now,

The area of the triangle.

= 1/2 (wx) siny

= 1/2 x (6.7 x 7.4) x sin 71
= 1/2 x 49.58 x 0.95

= 23.55

Thus,

The area of the triangle is 23.55 in².

Given that

The present value is € 45,000

The Future value is €52,500

Time period 1 year, 4 months and 20 days i.e. 1.38809 years

We need to find out the interest rate

Here we apply the RATE formula in the spreadsheet

The formula is

= RATE(NPER;PMT;-PV;FV;TYPE)

The PMT would be zero
