6 0

Answer:

Please see attached image

Step-by-step explanation:

The numbers on the upper row should be:  7   6   2

the number in the central disk should be    5

the bottom row should read  : 8   4   3

The addition on top row: 7 + 6 + 2 = 15

the addition on bottom row:  8 + 4 + 3 = 15

the addition on the central vertical column: 6 + 5 + 4 = 15

diagonal going down:    7 + 5 + 3 = 15

diagonal going up:   8 + 5 + 2 = 15

Write the equation of the line that is parallel to the line 7−4x=7y 7 − 4x = 7 y through the point (2,0).
Aleks04 [339]
We are given the line 7-4x=7y.

If we write this line in the form y=mx+k, then m is the slope of the line.

7-4x=7y

7y=-4x+7

y=(-4/7)x+1

the slope of the line is -4/7

Any line parallel to this line must also have a slope equal to -4/7.

We want precisely the one passing through (2, 0) and having slope -4/7.

Using the point-slope form of the equation of a line:

(y-0)=-4/7(x-2)

y=(-4/7)x+8/7

Answer: y=(-4/7)x+8/7

another form is   4x+7y-8=0

I  genuinely dont know help
pav-90 [236]

Answer:

-13 1/2 < -6/8

Step-by-step explanation:

*Any negative in either the numerator or denominator will make the entire fraction negative.

1/2  = .5

-13 1/2 = -13.5

-6/8 = -3/4

-3/4 = -0.75

-6/8 = -0.75

-13 1/2 = -13.5

Which means:

-13 1/2 < -6/8

Hope this helped.
