Y=x<br> y=-6x–14<br><br> (substitution method)

olga_2 [115]

Answer:

The solution is the point (-2,-2)

Step-by-step explanation:

we have

$y=x$ ----> equation A

$y=-6x-14$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$x=-6x-14$

Solve for x

$6x+x=-14\\7x=-14\\x=-2$

Find the value of y

substitute the value of x in the equation A

$y=x$

$y=-2$

therefore

The solution is the point (-2,-2)

Can you tell me if this is right

Rus_ich [418]

Mrs. Cali's Lower Quartile:2
Mrs. Cali's Upper Quartile:4
Mr. Ronald's Lower Quartile:4
Mr. Ronald's Upper Quartile: 7
Lower Quartile 2<4 (Mr.Ronald's is greater)
Upper Quartile 4<7 (Mr.Ronald's is greater)
Mr. Ronald's Upper and Lower Quartiles are Greater than Mrs. Cali's Upper and Lower Quartiles.
Mr. Ronald's Lower Quartile:4
Mrs. Cali's Upper Quartile:4
D is correct because Mrs. Cali's upper Quartile is at 4, which is where Mr. Ronald's Lower Quartile is.
Hopefully that helps!
Good Job getting it right on your own!
