Positive+positive= positive
negative+negative=positive
-7+10= negative
4/6 + 2/6= positive
-9.5+4= negative
First add 1/2 and 3/4 together by making 1/2, 2/4 then add 3/4 to get 5/4 or 1 1/4 then 10 - 1 1/4 is 8 3/4 which is the answer
Answer: y = -5; x = -2
Step-by-step explanation:
- 5y – 10x=45
- 3y + 10x = -5
Combining both equations
-8y = 40
y= 40/ -8
y = -5
Substitute y = -5 into any of the equations to get the value of x
-5 (-5) - 10x = 45
25 -10× = 45
-10x =45 -25
-10× = 20
Divide both sides by -10
x = -2
Mark as brainliest please
9x^3 + 30x^2 - 25x
step one: find the greatest common factor (GFC)
GFC=x
step two: factor out the GFC (write the GFC first. then in parentheses, divide each term by the GFC)
x(9x^3 over x + 30x^2 over x + -25x over x)
step three: simplify each term in parentheses
x(9x^2+30x-25) ...should be the answer
