It is the last equation. You square both sides.
Answer:
D 28
Step-by-step explanation:
31 own 13-15
3 own 1-3
31 - 3 = 28
Answer:
I had 18 cookies and I ate them all.
Step-by-step explanation:
This situation is represented by zero because 18-18 is 0.
X^2 + 3x = 24
completing the square
(x + 1.5)^2 - 2.25 = 24
(x + 1.5)^2 = 26.25
x + 1.5 = +/- sqrt26.25 = +- 5.123
x = -1.5 + 5.123 = 3.62 to nearest hundredth and
x = -1.5 - 5.123 = -6.62 to nearest hundredth
solution set is {-6.62, 3.62}
Answer:
x=3 y=-1
Step-by-step explanation:
To get the value of x you need to put in the second equation which is y=8-3x as the y value for the first equation which is 2x+3y=3 making it
2x+3(8-3x)=3
2x+24-9x =3
24-7x =3
-7x=-21
Multiplying both sides by -7
x= 3
After getting an x value you substitute it in the equation in order to find your y value which is
2x+3y=3
2(3)+3y=3
3y=-3
Multiplying both sides by 3
y= <u>-3</u>
3
y=-1
