(4x-6)+(8x+18)=180(adjacent angles are supplementary)

4x-6+8x+18=180

4x+8x-6+18=180

12x+12=180

12x=180-12

12x=168

x168/12

x=14

8x+18=y+3 (corresponding angles are equal)

8×14+18=y+3

130=y+3

-y=3-130

-y=-127

y=127

x=14, y=127

Answer:

x = 14 and y = 127

Step-by-step explanation:

we know that 4x-6 +8x+18 = 180

and 8x+18 = y+3

Let's first solve for x for the first equation.

12x = 180-18+6

x=14

Now solve for y for the second equation.

8(14) +18 = y + 3

y = 8(14) +18 -3

y = 127

Solve the quadratic equation by factoring: 15x^2+4x-4=0
joja [24]
We can factor by grouping. To do so, we multiply the leading coefficient with the constant at the end. In other words, a times c (ax^2 + bx + c).

15*-4 = -60

Now we need to split the b term into two pieces that multiply to -60 and add to 4.

-6 and 10 will work.

Now group one part of b with the 15x^2 and the other part with -4.

(15x^2 + 10x) + (-6x - 4)

Now factor both terms.

5x(3x+2) - 2(3x+2)

3x+2 is one of our factors and 5x-2 is the other.

(3x+2)(5x-2)=0

Now just find the zeros.

3x+2 = 0
3x = -2
x = -2/3

And

5x-2 = 0
5x = 2
x = 2/5

So the answer is x = -2/3 and x = 2/5

The Better Baby Buggy Co. has just come out with a new model, the Turbo. The market research department predicts that the demand
dlinn [17]

Answer:

$68

Step-by-step explanation:

We have been given the demand equation for Turbos as q=-4p+544, where q is the number of buggies the company can sell in a month if the price is $p per buggy.

Let us find revenue function by multiplying price of p units by demand function as:

Revenue function: pq=p(-4p+544)

pq=-4p^2+544p

Since revenue function is a downward opening parabola, so its maximum point will be vertex.

Let us find x-coordinate of vertex using formula \frac{-b}{2a}.

\frac{-b}{2a}=\frac{-544}{2\times -4}

\frac{-b}{2a}=\frac{-544}{-8}

\frac{-b}{2a}=68

The maximum revenue would be the y-coordinate of vertex.

Let us substitute x=68 in revenue formula.

pq=-4(68)^2+544(68)

pq=-4*4624+544(68)

pq=-18496+36992

pq=18496

Therefore, the company should sell each buggy for $68 to get the maximum revenue of $18,496.
