Answer:
3 -1 -2
5 1 6
Step-by-step explanation:
An augmented system has the coefficients for the variables and then the solution going across
Rewriting the equations to get them in the form
ax + by = c
-3x+y =2
3x-y =-2
5x+y = 6
The matrix is
3 -1 -2
5 1 6
I think it's t=778 not 100%
Answer:
p ≥ -10
Step-by-step explanation:
Divide both sides by-9:
When dividing or multiplying by a negative number, always flip the inequality sign:
-9p/-9 > = 90/-9
Cancel out the negatives:
9p/9 > = 90/-9
Simplify the fraction:
p > = 90/-9
Simplify the signs:
p > = -90/9
Find the greatest common factor of the numerator and denominator:
p >= -10 · 9/ 1 · 9
Factor out and cancel the greatest common factor:
p > = -10
Answer:
p = 3
Step-by-step explanation:
Hey there!
In order to find what p equals, we must first simply the equation to the most, then solve
SIMPLIFY
----------------------------------------------------------------------------------------------------------
-2 (3p - 6) + 4(5p - 8) = 2(2p + 3) + 4
-6p + 12 + 20p - 32 = 4p + 6 + 4
Now that we expanded the equation, we can combine all like terms
14p - 20 = 4p + 10
10p = 30
Now that we simplified the equation to the most, now we solve the equation
SOLVE
----------------------------------------------------------------------------------------------------------
10p = 30
p = 30/10
p = 3/1
p = 3
