Answer:
9, -8
Step-by-step explanation:
Answer:x=4 , y=-1
Step-by-step explanation:
X-y=5
X+y=3
If 1 and 2 are added then y will be eliminated
(1)+(2) gives : 2x=8 then x=4
Now substitute this value of x into either of the 2 equations and solve for y.
Let x=4 in (1) =4-y=5 = y=-2
32 In A Decimal Should Be 32 Over 100 so 32/100 Because A Percent Is Any Number Over 100 So Your Answer Would Be 32/100
A quadratic equation is an equation whose leading coefficient is of the second degree. The given quadratic equation can be matched with its solution as shown below.
<h3>What is a quadratic equation?</h3>
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
The given quadratic equation can be matched with its solution as shown below,
2x² − 32 = 0 → x = √(32/2) → x = {-4, 4}
4x² − 100 = 0 → x = √(100/4) → x = {-5,5}
x² − 55 = 9 → x = √(9+55) → x = {-8,8}
x² − 140 = -19 → x = √(-19+140) → x = {-11,11}
2x² − 18 = 0 → x = √(18/2) → x = {-3, 3}
