Answer:what grade is this
Step-by-step explanation:
Answer:
y = 2x + 3
Step-by-step explanation:
A line parallel to y = 2x has exactly the same slope but a different y-intercept, b.
Start with y = mx + b, and replace m with 2, y with -1 and x with -2:
-1 = 2(-2) + b, or
-1 = -4 + b.
Then b = 3, and the desired equation is y = 2x + 3
Answer:
Step-by-step explanation:
We would like to solve the given quadratic equation by <u>c</u><u>o</u><u>m</u><u>p</u><u>l</u><u>e</u><u>t</u><u>i</u><u>n</u><u>g</u><u> </u><u>the</u><u> </u><u>square</u><u> </u><u>method</u> .The given equation is ;
Subtract 12x to both sides ,
Here the co-efficient of x² is already 1 . So , we shall rewrite it as ,
Add 6² on both sides ,
Now LHS is in the form of (a-b)² = a²-2ab+b² ; so that ;
Simplify RHS ,
Put square root on both sides,
Add 6 on both sides,
Separate the two solutions ,
And we are done!
