Answer:
x=11, y=13
Step-by-step explanation:
3x-2y=7
3x-2(x+2)=7 . - x + = - -2*+2=-4
3x-2x-4=7
1x-4=7
x=7+4
x=11
y=x+2
y=11+2
y=13
f(x)= -2x-3
Step-by-step explanation:
Step 1:
Let the sequence given here is -5, -7, -9, -11, -13 ......
Here the first term (a₁) of sequence is -5
And the common difference between the numbers in the sequence is
d= (-7-(-5)) = -7+5 = -2
Let the number of terms be x
Step 2;
To find the sequence function basic arithmetic sequence formula is
aₙ = a₁ + d( x-1)
Applying the values we get
f(X) = -5 + ((-2)(X-1))
on simplification
f(X) = -5 + (-2X+2)
f(X)= -5+2-2X
f(X)= -3-2X
The carpenter can cut six full sized pieces of board.
Answer:
2nd
Step-by-step explanation:
using the quadric formula
do the math and you get the second one.
{-1/3,5/2}
Answer:
We have 6( n - 24 ) = 8N;
Then 6n - 144 = 8N;
-144 = 8N - 6N;
-144 = 2N;
N = (-144)÷2;
N = - 72;
