Answer 1:
<em>1.23456789 × (10-6) = 4.93827156</em>
Answer 2:
<em>(1.23456789 × 10) - 6 = 6.3456789</em>
Answer 3:
<em>1.23456789 × </em>
<em>= 0.000000123456789</em>
<em>Hope this helped! :)</em>
(x, y ) = (- 6, 3 )
Since both equations express y in terms of x, we can equate them
2x + 15 = -
x + 1
( add
x to both sides )
x + 15 = 1 ( subtract 15 from both sides )
x = - 14
( multiply both sides by 3 and divide by 7 )
x = ( 3 × - 14 )/7 = - 6
substitute x = - 6 into either of the 2 equations for y- coordinate )
y = ( 2 × - 6 ) + 15 = 3
solution : (x, y ) = ( - 6, 3 )
Answer:
Inversely Proportional
Step-by-step explanation:
2 x² + 2 x - 4 = 0
2 x² + 4 x - 2 x - 4 = 0
2 x ( x + 2 ) - 2 ( x + 2 ) = 0
( x + 2 ) ( 2 x - 2 ) 0 0
x + 2 = 0, or : 2 x - 2 = 0
x = - 2, 2 x = 2, x = 1
The x-intercepts are: ( -2, 0 ) and ( 1, 0 ).
