Answer:
x= 1/2 and x= -3
Step-by-step explanation:
Let's solve your equation step-by-step.
2x2+5x−3=0
Step 1: Factor left side of equation.
(2x−1)(x+3)=0
Step 2: Set factors equal to 0.
2x−1=0 or x+3=0
x=
1
2
or x=−3
X = 2i, -2i (I’m sorry if it does come back as wrong but it’s the only answer I got)
If by standard form, you mean ax+by= c, here is how to solve.
To write the equation in standard form, move each variable term to the left side of the equation and simplify.
y+2=3/5(x + 5)
y+2= (3/5*x) + (3/5*5)
y+2= 3/5x + (3*5)/5
y+2= 3/5x +15/5
y+2= 3/5x + 3
subtract 3/5x by both sides
-3/5x+y+2= 3
subtract both sides by 2
-3/5x+y=1
multiply by 5 to eliminate fraction
-3x + 5y= 5
ANSWER: -3x + 5y= 5
Hope this helps! :)
Answer:
45 i think
Step-by-step explanation:
i could be totally wrong about this but im pretty sure that if an initial price is 100 percentages are really easy. so 100 minus 60 is 40 and with a 5 percent tax thats 45.
I don't think your question was worded properly
