Answer:
y < -3 and
2x - 3y ≥ -15
Step-by-step explanation:
y < -3
Take any two points on the bold line
(0 , -5) and (-3 , -7)
Now find the slope for this line and then the equation of the line
Slope =
Slope, point equation,
y - y1 = m(x -x1)
Take any point from the shaded region and plugin the LHS of the equation.
(-6 , -5)
LHS = 2x - 3y
= 2*(-6) -3*(-5)
= -12 + 15
= 3 which is ≥ -15
2x - 3y ≥ -15
The markup percentage is .40778 -> 40.778%
$4015 = current price ; $2852 = original price
To find the mark up percentage:
First, find the difference between the current price and original price.
$4015 - $2852 = $1163
Second, divide the price difference by the current price to get the percentage.
1163/2852 = .40778
Check the math by multiplying the original price by the markup percentage and add the original price to it.
$2852 X .40778 + $2852 = $4015
Because multiply of these two number get you -32, one of these number must be negative.
And because sum of them are positive, positive number must be larger than that negative number (without minus sign)
So list of possible answers are:
-1, 32; -2, 16; -4, 8
And we can see that
-4+8 = 4
So these two numbers are 8 and -4.
It is just the name of the angle
angle RAB- A is the point and R and B are one of the ends
same with angle NAB, A is the point and N and B are one of the ends
Si a, b y r son números reales (y si a y b no son iguales a 0), ax+by = r se denomina ecuación lineal en dos variables. (Las “dos variables” son la x y la y.) Los números a y b se denominan los coeficientes de la ecuación ax+by = r. El número r se denomina constante del eje de ecuación + por = r.
