Answer:
3m+3p
Step-by-step explanation:
Sum of m and p is expressed as;
m + p (sum means addition)
If 3 is multiplied by the sum, this is expressed as;
3(m+p)
Expand
3m + 3p
Hence the required expression is 3m+3p
Answer:
it would be 10
Step-by-step explanation:
From the explicit formula:
an=3+(n-1)8
simplifying this we get:
an=3+8n-8
an=8n-5
thus
the recursive formula is:
an=an-1+
the missing part is the common difference which is 8
Answer:
1. x + 3y = 6 answer is x
=
6
−
3
y
2. 3x + 9y=-4 answer is x
=
−
4
3
−
3
y
but if u are talking about both of them together it has no solution
Step-by-step explanation:
This is what you do.
x - 2y = -8
4x - 3y = -17
Add 2y to both sides on the first equation.
x = 2y - 8
4x - 3y = -17
Now substitute the x value.
4(2y - 8) -3y = -17
8y - 32 - 3y = -17
Combine like terms
5y - 32 = 17
Add 32 to both sides.
5y = 15
Divide.
y = 3
Now find x by plugging in 3 into 1 equation.
x - 2(3) = -8
x -6 = -8
Add 6 to both sides.
x = -2
So you solution is (-2, 3).
I hope this helps love! :)
