Answer:
b = -6
Step-by-step explanation:
We use the general equation a*x^2 + bx + c = 0, the Quadratic Equation.
Compare it to 2x^2 - 6x - 20 = 0
b = -6 here
8 is the answer, though I think you could cram the extra ten people into the seventh bus and not hire the eighth one
Answer:
y = -x-2
Step-by-step explanation:
We are given a slope of -1 and the y intercept of -2
The slope intercept form of the equation for a line is
y = mx+b
where m is the slope and b is the y intercept
y = -1x +-2
y = -x-2
In order to find the answer to this, you must first turn 4 into a fraction (4/1)
12/25 divided by 4/1 is the same as 12/25 multiplied by 1/4, because when dividing fractions, you must use the reciprocal of the divisor and multiply.
12/25 x 1/4 = 12/100 = 6/50 = 3/25
Your answer should be 3/25<span />
Answer: y= -1
Step-by-step explanation:
Add 5 to both sides,
y-5+5=-9y-15+5
Simplify,
y=-9y-10
Add 9y to both sides,
y+9y=-9y-10+9y
Simplify,
10y=-10
Divide both sides by ten.
10y over 10 = -10 over 10
There you go!
