Answer:

38= 1, 2, 19 and 38

39= 1,3, 13 and 39

40= 1,2,4,5,8,10,20 and 40

common factors is 1

to know the factors in commas without finding the factor is to simply divide the number by each factor gotten, take for example i have 38 as the number and i have gotten 1, 2.

38 divided by 1 equals 38

38 divided by 2 equals 19

so they are the factors

8/15 divided by 1/3 reduce your answer
klio [65]
Here we can use fact than we can multiply fraction by inverse of fraction instead of dividing it.
Inverse of 1/3 is 3/1
Lets multiply it
\frac{8}{15}* \frac{3}{1}= \frac{24}{15}= \frac{24:3}{15:3}= \frac{8}{5}=1 \frac{3}{5} - its our result

Find the equation for intercept x 4 and y -7​
nadezda [96]

Answer:

y = \frac{-7x}{4} - 14

Step-by-step explanation:

The equation used to find the equation for a line with two intercepts is called point slope form. y - y_{1} = m(x - x_{1}) , where y_{1} and x_{1} are the intercept points and m is the slope.

However, we need the slope to use this formula.

Use m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}

m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}

m = \frac{((0) - (7))}{((4) - (0))}

m = \frac{-7}{4}

y - y_{1} = m(x - x_{1})

y - ( -7 ) = m ( x - ( 4 ) )

y - ( -7 ) = -7/4 ( x - ( 4 ) )

y + 7 = -7/4 ( x + 4 )

y + 7 = \frac{-7(x+4)}{4}

y + 7 = \frac{-7x-28}{4}

y + 7 = \frac{-7x}{4} - 7

y + 7 = \frac{-7x}{4} - 7 - 7

y = \frac{-7x}{4} - 14
