-x+y=-3, 3x+2y=9
1. multiply the first row by the second
-2x+2y=-6, 3x+2y=9
2. subtract the second row from the first row
-5x=-15
3. sole for x in the above equation
x=-15/-5
x=15/5
x=3
4. substitue x=3 into -2x+2y=-6
-2*3+2y=-6
5. solve for y in the above equation
-6+2y=-6
2y-6=-6
2y=0
y=0
6 therefore,
x=3 and y=0
Have a nice day :D
You draw a polygon on the graph
Answer:
I think f(t)=1/4t
Step-by-step explanation:
Because of you multiply 1/8 times 2, it gives you 1/4. Not 100% sure tho
Answer:
4,6,8
Step-by-step explanation:
Let x = 1st even integer
x+2 =2nd even integer
x+4 =3nd even integer
x+ x+2 + x+4 = 18
Combine like terms
3x+6 = 18
Subtract 6 from each side
3x+6-6=18-6
3x= 12
Divide by 3
3x/3 =12/3
x = 4
x+2 = 6
x+4 = 8
Answer:

Step-by-step explanation:
We are given 2 fractions.
1st fraction is Negative StartFraction 3 over 8
i.e.

2nd fraction is negative one-fourth
i.e.

We have to find the quotient when 1st fraction is divided by 2nd fraction.
<u>Definition</u> of quotient is given as:
Quotient is the result obtained when one number is divided by other number.

is converted to
and the 2nd fraction is reversed i.e.
if the fraction is
it becomes
and the sign
is changed to
.
Solving above:

So, the quotient is
.
