Answer:
Let's solve your system of equations by elimination.
8x+9y=48;12x+5y=21
Steps:
Multiply the first equation by 5,and multiply the second equation by -9.
5(8x+9y=48)
−9(12x+5y=21)
Becomes:
40x+45y=240
−108x−45y=−189
Add these equations to eliminate y:
−68x=51
Then solve−68x=51for x:
−68x
/−68
=
51
/−68 (Divide both sides by -68)
x= −3
/4
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
8x+9y=48
Substitute
−3
/4
8x+9y=48:
8(
−3
/4
)+9y=48
9y−6=48 (Simplify both sides of the equation)
9y−6+6=48+6 (Add 6 to both sides)
9y=54
9y
/9 = 54
/9 (Divide both sides by 9) y=6
<em><u>Answer: x= −3
/4 and y=6</u></em>
Hope This Helps! Have A Nice Day!!
The point slope form is
y-y1=m(x-x1)
where
m=slope
and you are given a point (x1,y1)
we are iven that slope=2
and a poin is (3,10)
3=x1
10=y1
y-10=2(x-3)
the answer is
y-10=2(x-3)
The value of f(0) is 12.
<h3>What is graph?</h3>
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
By considering the graph we have to find f(0) which means we have to find that point where x- coordinate is zero.
Also, which shows that 12 the function f(x)
So, taking the point is (0,12) we can get f(0)= 12.

Answer:
1/6 or 25
Step-by-step explanation:
1/3=10/30
3/10=9/30
1/5=6/30
together is 25/30, which leaves the rest, 5/30 or 1/6 or 25 cookies.
