Answer:
-2
Step-by-step explanation:
y=-2x+5
y=mx+b where m=slope and b=y-intercept
Answer:
y=-(4x/3) -1
Step-by-step explanation:
Slope=m= -4/3
y intercept = c = -1
now using equation;
y= mx+c
y= (-4/3)x+(-1)
y=-(4x/3) -1
<span>The rule of signs is the same for multiplication and division.
Two numbers with the same sign, multiplied or divided, the answer is positive.
Two numbers with different signs, multiplied or divided, the answer is negative. </span>
Answer:
≈ -5.1857
≈ -5.4857
≈ 3.7262
Step-by-step explanation:
Rewrite the equation system as:
Now, write the system in its augmented matrix form:
applying row reduction process to its associated augmented matrix:
Swap R1 and R3, and then Swap R1 and R2:
R3+2R1
3R2+2R1
15R3+20R2
Now we have a simplified system:
From (3):
(4)
Replacing (4) in (2)
(5)
Finally replacing (5) and (4) in (1)
