Grandma Gertrude gave 13 pieces of jewelry and Grandma Fien gave y pieces of jewellery
total jewellery given =y+13
there are five sisters
so each sister will receive (y+13)/5 pieces of jewellery
Answer:
2.) Infinitely many solutions
3.) No solutions
Step-by-step explanation:
To solve systems of equations graphically, you need to find where they intersect
2.) First put each equation in the form y=mx+b
x-y=6 -> y= x-6
2x=12+2y -> y= x-6
Then, graph each line
Since we have the same equation, the lines are on top of each other so there are infinitely many solutions as they intersect everywhere.
To check, plug a point in from the graph into both equations and you should get 0=0
3.) First put each equation in the form y=mx+b
1/2x-y=4 -> y=1/2x-4
2y=x+6 -> y=1/2x+3
Then, graph each line
Since the lines have the same slope but a different y intercept, the lines are parallel. Therefore, there are no solutions as they do not intersect.
To check your answer, you would one equation as the y in the other equation.
2(1/2x-4)=x+6, then solve for x
Then plug that x into the original equations, and you'll see they are not equal. Hope that helps!
For this case we have the following rational expression:
What we must do for this case, is to factor the numerator and the denominator.
We have then:
Then, canceling similar terms we have:
Then, the function is not defined for the values that make the denominator zero.
We have then:
And on the other hand, a zero of the function is:
Answer:
a zero of the function is:
the function is not defined for the value:
The cc’d between 23 and 46 is 23
Answer:
Step-by-step explanation:
6^2+b^2=11^2
121-36=b^2
Square root of 85
