What is the y-value of the solution to the system of equations? 3x 5y = 1 7x 4y = −13 −3 −1 2 5

The amount that Rebecca pay for the sweaters and jeans before tax for this case is $26.79

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

We're specified that:

Before taxing, the price to be paid is real price (marked on the items) - discount offered on them.

Now, we get:
Price of each shirt is assumingly same, and so as for both of shorts. The discounts would be same for all shirts, and the discount will be same for all shorts.

So sum of discounted price = discount on summed price.
Thus, discoutned price of 3 shirts = 40% discount on $25.65

= $25.65 - 40% of $25.65

We get this:

[tex]25.65 - \dfrac{25.65}{100} \times 40 = 25.65 \approx 0.6 = 15.39[/tex] (in dollars)

Similarly, we get:

Discounted price of shorts=  $22.80 - 50% of %22.80 = 22.80 - 11.40 = 11.40 dollars

Thus, the total discounted price = discounted price of shirts and shorts= $15.39 + $11.40 = $26.79

Thus, the amount that Rebecca pay for the sweaters and jeans before tax for this case is $26.79

Answer:

18 hours

Step-by-step explanation:

Jena takes three times as long as Shirley.

3 Times 6 = 18

The domain of the function is a real number and the range of the function will be (-11, ∞).

The domain means all the possible values of the x and the range means all the possible values of the y.

The function is given below.

f(x) = 3x² + 6x – 8

The range of the function will be

f(x) = 3x² + 6x – 8

f(x) = 3x² + 6x + 3 – 11

f(x) = 3(x² + 2x + 1) – 11

f(x) = 3(x + 1)² – 11

Then the range of the function will be from -11 to infinity.

Area of a trapezoid: h(a + b)/2

height, h = 3 ft

base 1, a = ?

base 2, b = 16 ft

area, A = 36 ft^2

36 = 3(a + 16)/2

72 = 3(a + 16)

24 = a + 16

8 = a

Answer:

Vertical.

Step-by-step explanation:

Slope judges the vertical angle in which the line is moving, from point to point. If the line is vertical in it of itself, there will be no specific point in which you can use to define the slope. The denominator of run is always 0, and having a 0 for denominator will result in the fraction being undefined. You cannot have parts of nothing, mathematically.

Vertical. Please consult the explanation for more details.

Answer:

y=-4x-3

Step-by-step explanation:

Hi there!

We are given the following two points: (-2,5) and (-1,1)

We want to write the equation of the line that passes through these two lines in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

First, let's find the slope

The formula for the slope (m) calculated from 2 points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to calculate the slope, but let's label the value of the points to avoid any confusion

[tex]x_1=-2\\y_1=5\\x_2=-1\\y_2=1[/tex]

Now substitute into the formula

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{1-5}{-1--2}[/tex]
Simplify

m=[tex]\frac{1-5}{-1+2}[/tex]

Subtract

m=[tex]\frac{-4}{1}[/tex]

Divide

m=-4

Now substitute -4 as m into the equation:

y=-4x+b

Now we need to find b

As the equation passes through both (-2, 5) and (-1, 1), we can use either point to help solve for b.

Taking (-2,5) for example:

Substitute -2 as x and 5 as y:

5=-4(-2)+b

Multiply

5=8+b

Subtract 8 from both sides

-3=b

Substitute -3 as b.

y=-4x-3

Answer:

Picture so I can solve it

Answer: 12 minutes

Step-by-step explanation:

Time taken by 2 people = 60 minutes

The time taken by 1 person is double that = 60 x 2 = 120 minutes

So the time taken by 10 people = 120 minutes / 10 people = 12 minutes

Answer: 12 minutes.

Step-by-step explanation: For two people, it takes an hour to paint a fence. With ten people, however, it takes very little time to paint a fence.  10 people are 5 times more people than when you have only 2.  It would only take 12 minutes because it takes 5 times less time with 10 people than with only two.

Answer:

Option 1: 43π feet

Step-by-step explanation:

We are given that:

encloses garden with circular fence

garden measures 43 feet across = diameter

To find how much fencing is needed, we have to find the cicumference of the circular fence using the formula:

C = 2πr

C = Circumference

r = radius = half the diameter

We are given the diameter, so we just do half of it to get the radius

43 ÷ 2 = 21.5

r = 21.5

Now we substitute this into the formual:

C = 2πr

Substitute radius into formula

C = 2π(21.5)

Multiply 2 and 21.5

C = 43π

144 Inches or 12 Feet

Step-by-step explanation

7 feet converted to inches is 84 So 84+60=144

And if you convert 60 inches into feet it would be 5

Answer:

144 inches

Step-by-step explanation:

1 ft = 12 inches

7 ft = 12 x 7 inches

7ft = 84 inches

Ice path you are floating on = 84 inches

other ice path = 60 inches

all together = 84 + 60

=> 144 inches
