If you are solving a system of equations by graphing it, the point of intersection makes both equations true! C:
Ok so
250 left for student desks
250≥8n
n=number of desks
solve
divide both sides by 8
31.25≥n
round down since we cannot have a decimal desk
31 desks
but, the teacher has 1 desk also so add 1
31+1=32
8*2*5= 80 because volume= length*width*height
Answer:
100
Step-by-step explanation
the width squared plus the height squared
which is 8*8+6*6
=64+36
=<u>100</u>
Answer:
B. x= 4
Step-by-step explanation:
We know that,
The result for the intersection of the secant and the tangent is given by by the figure below,
According to the question, we have,
i.e.
i.e.
Now, the solution of a quadratic equation is given by,
So, we get,
implies a= 1, b= 12 and c= -64.
Thus, the solution is given by,
i.e.
i.e.
i.e.
i.e. and i.e.
i.e. and i.e.
i.e x= -16 and x= 4.
Since, length cannot be negative.
So, we have, x= 4.
