Answer:
x=3,y=0
x=-1,y=0
Step-by-step explanation:
We will have to factorise to get the value of x before solving for y
Let's solve
y=x^2-2x-3
To factorise x
x^2-3x+x-3
x(x-3)+1(x-3)
(x-3)+(x+1)
x-3=0
x=3
x+1=0
x=-1
Let's substitute the value of value to get the value for y
y=x^2-2x-3
When x is 3
y=3^2-2(3)-3
y=9-6-3
y=0
When x is-1
y=(-1)^2-2(-1)-3
y=1+2-3
y=0
Therefore when x is 3,y is 0
When x is -1,y is 0
Answer:
The answer to your question is the letter A.
Step-by-step explanation:
a) - c < 0 This option is correct c > 0 but -c < 0 or 7 > 0 and -7 < 0
b) c < -a This option is incorrect. 7 > - (-4) or 7 > 4
c) c < - b This option is incorrect. 7 > - 1
Conclusion
The right answer is the first choice because is the only that satisfies the inequality.
Answer: The required number of boys in the class is 18.
Step-by-step explanation: Given that in math class, the girl to boy ratio is 8 to 6 and there are 24 girls in the class.
We are to find the number of boys in the class.
Let 8x and 6x represents the number of girls and boys in the class.
Then, according to the given information, we have

Therefore, the number of boys in the class is given by

Thus, the required number of boys in the class is 18.
