Hello
if m s : sum and p : <span> product
the </span><span> quadratic equation is : x²-sx+p=0
s = 5 p=-24
x²-5x-24 = 0 </span>
Answer:
- t = -5/2
- -21
Step-by-step explanation:
3t - 7 = 5t
~Subtract 3t to both sides
-7 = 2t
~Divide 2 to both sides
-7/2 = t
~Find 6t with what we found for t
6(-7/2)
-21
Best of Luck!
To find the x-intersept, just set y = 0 into the equation, then solve it for x:
-2x + 5 * 0 = -10
-2x + 0 = -10
-2x = -10
x = (-10)/(-2)
x = 5 <----- this is the answer.
I hope this helps. =)
His work should have looked like this.
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10 When he added in both sides, he subtracted 10 from 10,
5x = 20 instead of adding 10 from 10 to make 20.
x = 4
2(4) + y = 5
8 + y = 5
y = -3
I think it is 1 I am not sure tho
