Mathematics
1 answer:
Mnenie [13.5K]4 years ago
6 0

Answer:

y = 3/4x+8

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

    = (8-2)/ (0- -8)

     = (8-2)/(0+8)

     = 6/8

     3/4

The y intercept is 8   The y intercept is where x =0

The equation of a line is

y = mx+b where m is the slope and b is the y intercept

y = 3/4x+8

A computer printer can print a 660-word document in 35 seconds. At this rate, how many seconds are required to print a document
lesya [120]

Set up a proportion:


\frac{660}{35} = \frac{840}{x}


The numerator represents the words in the document, and the denominator represents the seconds it takes to print the document.


You can simplify the first fraction to make multiplication easier. Divide both the numerator and denominator by 5:


\frac{660}{35} \div \frac{5}{5} = \frac{132}{7}


\frac{132}{7} = \frac{840}{x}


Cross multiply both fractions:


132x = (840 \times 7) = 5880


Divide both sides by 132 to get x by itself:


5880 \div 132 = 44.54


\boxed{x = 44.54}


It will take 44.54 seconds to print the 840-word document.

John is solving x^2 + 4x + 8=0 by completing the square. Which step would be part of John's solution.?
SOVA2 [1]

Answer:

(x + 2) ^{2}  =  - 8

Step-by-step explanation:

{x}^{2}  + 4x + 8 = 0 \\  {x }^{2}  + 4x =  - 8 \\  {x}^{2}  + 4x + 4 =  - 8   + 4 \\ ( x + 2)^{2}  =  - 4
