Step-by-step explanation:
Answer:
x = 0.781 , y = -1.219
and
x = -1.281 , y = -3.281.
Step-by-step explanation:
Since both of the x terms are equal to y we can equate the x terms:-
-2x^2 = x - 2
2x^2 + x - 2 = 0
x = [-1 +/- √(1^2 - 4*2*-2) ] / 4
= ( - 1 +/- √(17)) / 4
= 0.781, -1.281.
When x = 0.781 y = 0.781 - 2 = -1.219.
when x = -1.281 , y = -1.281 - 2= -3.281.
Answer:Using the distributive property, the problem becomes:
5x2 * 3x5 + 5x2 * 2x - 5x2 * 8 and each set of factors may be rearranged as:
5 * 3 * x2 * x5 + 5 * 2 * x2 * x - 5x2 * 8 which becomes
15x7 + 10x3 - 40x2
