You have already done half of it. Now substitute for x1 = 4 and y = 5
y - 5 = 6/7(x - 4)
Multiply everything by 7 to remove fractions
7y - 35 = 6(x - 4)
7y - 35 = 6x - 24
-6x + 7y = -24 + 35
-6x + 7y = 11

Some people prefer a positive number in front of x so multiply by -1
6x - 7y = -11

You can check the answer by testing it works for both of the original points
6x4 - 7x5 = 24 - 35 = -11 true
6x-3 - 7x-1 = -18 - -7 = -11 true

Ed needed to extend the string on his kite. The current string was eight and three fourths feet. He cut a piece of string that m
Pani-rosa [81]

The new length of the string is  (13 + 1/4) feet, then the correct option is the last one (counting from the top)

<h3> What is the new length of the string?</h3>

We know that the current string was (8 + 3/4) feet in length. Then they add another piece that measures 4.5 feet.

The new length of the string is given by the addition of the above two lengths, we will get:

L = (8 + 3/4) feet + 4.5 feet

We can rewrite the second length as a mixed number:

4.5 = 4 + 1/2 = 4 + 2/4

Replacing that we get:

L = (8 + 3/4) ft + 4.5 ft

  =  (8 + 3/4) ft + (4 + 2/4) ft

  = (8 + 4) ft + (3/4 + 2/4) ft

  = 12ft + 5/4ft = 12ft + (4/4 + 1/4)ft = (13 + 1/4)ft

The new length of the string is  (13 + 1/4) feet, then the correct option is the last one (counting from the top).

Which function has a removable discontinuity?
attashe74 [19]

If the function factors and the bottom term cancels, the discontinuity at the x-value for which the denominator was zero is removable, so the graph has a hole in it. After canceling, it leaves you with x – 7. Therefore x + 3 = 0 (or x = –3) is a removable discontinuity..

(a) Work out the reciprocal of 1.25
Oxana [17]

Answer:

0.8 OR \frac{4}{5}

Step-by-step explanation:

The reciprocal of any number is the number that it multiplies by to equal 1.

The reciprocal can be found by simply converting the number into a fraction and then 'flipping' the fraction as any number multiplied by its reciprocal is 1.

E.g.

No. X/Y * Y/X (its reciprocal) = 1

\frac{x}{y} *\frac{y}{x} =\frac{xy}{xy} =1

So, to find the reciprocal of 1.25,we should first convert 1.25 to a fraction.

1.25 = 125/100

\frac{125/25}{100/25}=\frac{5}{4}

Now we just flip 5/4 to get our reciprocal:

\frac{4}{5} = 0.8

Test: 0.8 * 1.25 = 1

The reciprocal of 1.25 (\frac{5}{4}) is 0.8 (\frac{4}{5}).

Hope this helped!
