First calculate x.
since its an isosceles triangle, and the 2 isosceles sides r same so the base angles are the same
therefore 7x + 5 = 9x - 13
5 + 13 = 9x - 7x
2x = 18
x = 9
so when we have x = 9, just use the angle sum of triangle to calculate y.
4y + 7x9 + 5 + 9x9 -13 = 180
4y + 136 = 180
y= 11
so there u have it, x is 9 ans y is 11

To find slope it is rise over run which is 20/60 but that can be reduced to 1/3. Do your equation of the line is y=1/3x

Use deductive reasoning to show that the following procedure always produces the number 6. Procedure: Pick a number. Add 4 to th

Flauer [41]

Answer:

procedure always produces 6

Step-by-step explanation:

Let 'n' be the unknown number

Add 4 to the number : n+4

multiply the sum by 3.

multiply the sum n+4 by 3

$3(n+4) is 3n+12$

Now subtract 6, so we subtract 6 from 3n+12

$3n+12-6=3n+6$

finally decrease the difference by the tripe of the original number

triple of original number is 3n

$3n+6-3n= 6$

so the procedure always produces 6
