Y=3x+30
because if you look she automatically makes $30, and her salary goes up every time cone by 3<span />

4 0
So since the first point (0,30) has an x intercept of 0 and a y intercept of 30
We can immediately eliminate any that do not have an y intercept of 30
So choices a and b are automatically incorrect

and now to solve for slope we do (y2-y1)/(x2-x1)
so we can choose any two points so I'll use points (0,30) and (1,33)

so 33-30=3
and 1-0=1

so we then do rise(y) over run (x)
and we now know our unit rate is 3x

so your answer is D

Answer:

Option (B). Perimeter of the quadrilateral ABCD= 14.6 units

Step-by-step explanation:

From the figure attached,

Coordinates of the vertices are A(3, 5), B(1, 3), C(3, -1), D(5, 3).

Length of AB = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

                      = \sqrt{(3-1)^2+(5-3)^2}

                      = \sqrt{8}

                      = 2.83 units

Length of AD = \sqrt{(3-5)^2+(5-3)^2}

                      = \sqrt{8}

                      = 2.83 units

Length of BC = \sqrt{(1-3)^2+(3+1)^2}

                      = \sqrt{20}

                      = 4.47 units

Length of DC = \sqrt{(5-3)^2+(3+1)^2}

                       = \sqrt{20}

                       = 4.47 units

Perimeter of the quadrilateral = AB + AD + DC + BC

                                                 = 2.83 + 2.83 + 4.47 + 4.47

                                                = 14.6 units  

Option (B) is the answer.

Answer:

12 pencils

Step-by-step explanation:

let no. of pencils bought be x.

54 - 0.75x - 2.50 = 42.50

9 = 0.75x

x = 12
