For the first one Y = -6
3x + 2Y = -16
-2y -2y
3x = -18y
— —
3x 3x
Then divide -18y divided by 3X
To get Y= -6
Hope that helped!
Answer:
7
Step-by-step explanation:
Q R
T S
I put the letters here in order, a clockwise order starting at Q.
If you look at our diagram you will see that RT and QS are actually the diagonals of this rectangle.
The diagonals of a rectangle are congruent.
We have the measurement of RT = the measurement of QS.
That is we have this equation: 4x-16=x+5.
4x-16=x+5
Subtract x on both sides:
3x-16= 5
Add 16 on both sides.
3x = 21
Divide both sides by 3.
x = 7
Answer:
2007
Step-by-step explanation:
we have

This is a vertical parabola open upward
The vertex represent a minimum
p(x) is the population in thousands for a species of fish
x is the number of years since 1997
Remember that p(x) is in thousands
so
If the population reach 66,530 fish
then
the value of p(x) is equal to
p(x)=66.53
substitute in the quadratic equation



Solve the quadratic equation by graphing
The solution is x=10 years
see the attached figure
therefore
Find the year
Adds 10 years to 1997
1997+10=2007
315/356 = about 0.88 or 88%. <span>
64/144= about .044 or 44%
</span><span>They will not have equal opportunity to get the math class they requested, if both percents were equal, it would be fair. For honors students, 88% of them will get the class they requested, but for non honors students it's 44%.</span>
