suppose the equation for line A is given by 2x-5y=15, if line A and B are parallel and the point (-10,3) lies on line B, then write the equation in slope intercept for line b.

Answers

Answer 1

Answer:

y=2/5x + 7

Step-by-step explanation:

First, you have to rewrite 2x-5y=15 to slop intercept form.

To do that you have to first subtract 2x from both side to cancel it out.

2x- 2x-5y= 15 -2x.    

-5y= -2x+15

Next, you divide 5 on both side to leave the y by itself.

y= -2x/-5 + 15/-5

Simplify

y= 2/5x + (-3)                     2/5 is our slope

Now that we found the slope, we need to the y-intercept of line b

y=2/5x + b

To find the y-intercept, we substitue x and y with the coordinates (-10,3)

3= 2/5(-10) +b

Now we just solve for b

3= -4 +b

3-(-4) = b

7=b

Now we have identified that 7 is the y intercept

The full equation is y= 2/5x +7

I hope this helped :)

At a picnic there are 7 pieces of fruit for every 4 vegetables. If there are 28 pieces of fruit, how many vegetables are there?

Answers

Step-by-step explanation:

There are 7 fruits for every 4 vegetables.

If there are 28 fruits, the number of fruits have multiplied by 4. This means that the number of vegetables have multiplied by 4 as well.

=> 4 * 4 = 16 vegetables.

Hence there are 16 vegetables.

What is 0.16666666666666666 as a fraction?

Answers

Answer:

[tex]\frac{1}{6}[/tex]

Step-by-step explanation:

We require to create 2 equations with the repeating 6 placed after the decimal point. Then subtracting the equations eliminates the repeating part.

let x = 0.1666....... ( multiply both sides by 10 and 100 )

10x = 1.666...... → (1)

100x = 16.666...... → (2)

Subtract (1) from (2) to eliminate the repeating decimal, thus

90x = 15 ( divide both sides by 90 )

x = [tex]\frac{15}{90}[/tex] = [tex]\frac{1}{6}[/tex]

Thus

0.16666......... = [tex]\frac{1}{6}[/tex]

a. About how far is it from Amarillo to Oklahoma City?
b. Driving at a constant speed of 70 miles per hour, will it be possible to make this
trip in 3 hours?

Answers

Answer:

a). 240 miles (Approx)

b). Trip can't be covered in 3 hours with a constant speed = 70 miles pr hour

Step-by-step explanation:

a). As the scale has been given at the bottom. Length of the scale represents the distance between two points.

  Now by measuring the distance between these stations, approximate distance between Amarillo and Oklahoma = 4(length of the scale)

  = 4×60

  = 240 miles.

b). Driving at a constant speed = 70 miles per hour

   Distance covered in 3 hours = 70 × 3

                                                   = 210 miles

Therefore, distance of 240 miles between these stations can't be covered with the driving speed 70 miles per hour in 3 hours.

The perimeter of the tennis court is 228 feet. What are the dimensions of the court? Write the equation for the situation: What is the width of the court? What is the length of the court?

Answers

Answer:

It’s 36 by 78 tennis court

width = 36 ft.

length = 78 ft.

Step-by-step explanation:

2(w+2w+6)=228 feet

2w+4w+12=228

6w=228-12

6w=216

w=36

So, 2w+6=78

It’s 36 by 78 tennis court

width = 36 ft.

length = 78 ft.

The dimensions of the tennis court can be determined by solving the equation system: width (w) = 42 feet and length (l) = 96 feet.

To find the dimensions of the tennis court, we can set up a system of equations based on the given information:

Equation for the perimeter:

The perimeter of a rectangle is given by the formula:

P = 2(length + width).

In this case,

the perimeter is 228 feet, so the equation gives:

228 = 2(l + w)

Equation relating length and width: It is stated that the width (w) is equal to the length (l), which can be expressed as:

w = l

To solve the system of equations:

Substitute the value of l from the second equation into the first equation:

[tex]228 = 2((2w + 6) + w)[/tex]

Simplifying the equation:

[tex]228 = 2(3w + 6)[/tex]

Divide by 2 on both sides

[tex]114 = 3w + 6[/tex]

Subtract by 6 on both sides

[tex]108 = 3w[/tex]

Divide by 3 on both sides

[tex]w = 36[/tex]

Substituting the value of w back into the second equation:

[tex]l = 36[/tex]

Therefore, the width of the tennis court is 36 feet, and the length is 96 feet.

The standard form of the polynomial -4w(w²-9) will be -4w³+36w.

What are polynomials?

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

The highest degree of terms is written first, followed by the next degree, and so on, to represent a polynomial in standard form.

The given expression can be converted to the standard form as below,

P = -4w(w²-9)

P = ( -4w) x (w²) + ( 4 x 9w)

P = -4w²+36w

Therefore, the standard form of the polynomial -4w(w²-9) will be -4w³+36w.
