Just plug in a = 5, y = -3 in that!
2a + ay = 2(5) + 5(-3) = 10 -15 = -5
thats it!
Answer:
Step-by-step explanation:
-7y = -10x - 8
y = 10/7x + 8/7
I think it is asking for the answer, therefore it would be AB = 10.7
The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
It should be the number 55. <span> ❤</span>please mark me as brainliest ❤
