Answer:
<u>Group the Variable's</u>:
2 x - 5 + 7 y - 3 = 9 x - 1 - y -8
2x -9x + 7y +y = -1 -8 +5 + 3
-7x + 8y = -1
<u><em>From this find x and y</em></u>
<u>For X</u>
-7x + 8y = -1
-7x = -1 -8y
7x = 8y + 1
x = (8y +1)/7
<u>For Y</u>
-7x + 8y = -1
8y = -1 +7x
y = (7x -1)/8
Answer:
y=-2
Step-by-step explanation:
The formula for inverse variation is
xy =k
if y=7 when x=-2, we can substitute these numbers in to find k
(-2)(7) =k
-14 =k
The equation becomes
xy = -14
Let x =7
7y = -14
Divide each side by 7
7y/7 = -14/7
y = -2
Given that : g(x) = 4x + 4 .
So , in order to find the value of g(4) , just substitute x = 4 in the given function .
Here ,
=> g(x) = 4x + 4 .
=> g(4) = 4 × 4 + 4 .
=> g(4) = 16 + 4 .
=> g(4) = 20 .
<u>Hence</u><u> </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>2</u><u>0</u><u>. </u>
6 because 1 in 1/6 represents how many he took and the denominator in the other fractions gets smaller because it's less and less each time
10x - (5+3x)
10x - 8x
10x - 8
18x
