Answer:

y-2=\frac{1}{3}(x-3)

Step-by-step explanation:

we know that

The equation of the line into point slope-form is equal to

y-y1=m(x-x1)

in this problem we have

m=\frac{1}{3}

(x1,y1)=(3,2)

substitute the values in the formula

y-2=\frac{1}{3}(x-3)

Y - y1 = m(x - x1)
slope(m) = 1/3
(3,2)....x1 = 3 and y1 = 2
now we sub
y - 2 = 1/3(x - 3)

Name the property shown by the statement. (8 + 7) + 3 = 8 + (7 + 3)
Evgen [1.6K]

Step-by-step explanation:

Associative Property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped', I mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Example: 3+(2-4) can be rewritten as (3+2)-4.

hope it helps!

Find the area of the triangle formed by the origin and the points of intersection of the parabolas with equations y=−3x2+20 and
sergejj [24]

Answer:

Area = 21 unit²

Step-by-step explanation:

We have one point of triangle = (0,0)

The other points can be solved, intersection means

              −3x²+20 = x²−16

               4x² = 36

               x² = 9

               x = ±3  

when x = 3,      y =  3²−16  = 9 -16 = -7  , point is (3,-7)

when x = -3,      y =  (-3)²−16  = 9 -16 = -7  , point is (-3,-7)

We need to find area of triangle with points  (0,0), (3,-7) and (-3,-7).

Area of triangle is given by

         Area =\frac{1}{2}\begin{vmatrix}0 & 0 & 1\\ 3 & -7 & 1\\ -3 & -7 & 1\end{vmatrix}

  Area = \frac{1}{2}\left ( 0(-7\times 1-(1\times -7))-0(3\times 1-(1\times -3))+1(3\times -7-(-3\times -7)\right )\\\\Area =\frac{1}{2}(-21-21)=-21=21unit^2

Area = 21 unit²

Mary month earnings can be given as R(x)=13x+155 where x equals the number of hours worked josies monthly are given as Q(x)=9x+3
tatuchka [14]

Answer:

45hours

Step-by-step explanation:

Given

Mary month earnings to be R(x)=13x+155

Josies monthly earning is given as Q(x)=9x+335

If Josie and Mary work to earn the same salary, then R(x) = Q(x)

13x+155 = 9x+335

subtract 155 from both sides

13x+155-155 = 9x+335-155

13x = 9x+180

subtract 9x from both sides

13x-9x = 9x+180-9x

4x = 180

x = 180/4

x = 45

Since  x equals the number of hours worked by Josie and Mary, this means that Josie and Mary must work for 45hours to earn the same salary
