Answer:
Step-by-step explanation:
A)
<span>|x + y = 5 </span>
<span>|2x - y = 7; </span>
<span>b) </span>
<span>|2x + y = 5 </span>
<span>|x - y = 2 </span>
<span>c) </span>
<span>|3x + y = 6 </span>
<span>|4x - 3y = -5 </span>
<span>d) </span>
<span>|1/(x - 1) = y - 3 </span>
<span>|x - y = -2 </span>
<span>e) </span>
<span>|(9x + 4y)/3 - (5x - 11)/2 = 13 - y </span>
<span>|13x - 7y = -8 </span>
<span>Answer: </span>c<span> and </span>e<span> has solution (1; 3)</span>
Answer:
(-9,2)
(3,-6)
(6,-8)
(9,-10)
Step-by-step explanation:
y=-2/3(9)-4
y=-2/3(3)-4
y=-2/3(6)-4
y=-2/3(9)-4
(x+3)(2x-6)=26
2x(to the second power)-18=26
2x(to the second power) -18-26=26-26
2x(to the second power)-44 = 0
x=square root of 22,x= negative square root of 22
decimal form : x = 4.69042,x= -4.69042
