Point-slope equation of a line:

y - yo  =  m(x - xo)
Where m is the slope (1/4) and (xo,yo)=(2,-2)

y + 2 =  \frac{1}{4} (x - 2)
y + 2 =  \frac{1}{4} x -  \frac{1}{2}
y =  \frac{1}{4} x -  \frac{5}{2}
The y-intercept is -5/2, the graph is shown in the photo.

This is my last question I need help with.

Answer:

Option 1

Step-by-step explanation:

The formula of constant porpotionality is

y = kx

or

y =  \frac{k}{x}

where k is the constant of porpotionality.

This equation is direct variation so we will use

y = kx

The equation is in the form

y = 1.5x

1.5 is in k place so the constant of porpotionality is 1.5

Find the area, please help me, having a hard time getting through tonight’s homework. Complex/Compound area. Thanks!

Since the bottom shape is a semi-circle, the 3yd is the radius making the triangle's area 7 x 3 / 2 = 10.5

The semi-circle's area is \pi 3^{2} /2 = 14.14

Combined, you get an area of 10.5 + 14.14 = 24.64yd^{2}

Hey can you please help me posted picture of question :)

The given trinomial can be factored using factorization as

x²-x-12
=x²-4x+3x-12
=x(x-4)+3(x-4)
=(x-4)(x+3)

Thus x-4 and x+3 are the factors of the given trinomial. From these we can see x+3 is listed in option A

So the answer to this question is Option A

Answer:

  $2.50

Step-by-step explanation:

The question asks for the total cost of a notebook and pen together. We don't need to find their individual costs in order to answer the question.

Sometimes we get bored solving systems of equations in the usual ways. For this question, let's try this.

The first equation has one more notebook than pens. The second equation has 4 more notebooks than pens. If we subtract 4 times the first equation from the second, we should have equal numbers of notebooks and pens.

  (8n +4p) -4(3n +2p) = (16.00) -4(6.50)

  -4n -4p = -10.00 . . . . . . . . . . . simplify

  n + p = -10.00/-4 = 2.50 . . . . divide by the coefficient of (n+p)

The total cost for one notebook and one pen is $2.50.

__

<em>Additional comment</em>

The first equation has 1 more notebook than 2 (n+p) combinations, telling us that a notebook costs $6.50 -2(2.50) = $1.50. Then the pen is $2.50 -1.50 = $1.00.

One could solve for the costs of a notebook (n) and a pen (p) individually, then add them together to answer the question. We judge that to be more work.
