On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, 1) and (0, 3). Everything to th

Answer:

  (c)  y > 2/3x + 3

Step-by-step explanation:

Shading to the left of a line with positive slope is the same as shading above that line. That, and the fact that the line is dashed, means the inequality will be of the form ...

  y > ( ) . . . . . . the solution set is y-values greater than those on the line

__

There are two choices in this form. You can see which one will include the point (-3, 1) on the boundary line:

<u>y > 3/2x +3</u>

  y > (3/2)(-3) +3 = -3/2 . . . . . not 1. This is not the correct inequality

<u>y > 2/3x +3</u>

  y > (2/3)(-3) +3 = 1 . . . . . . . the inequality we're looking for

Aunt Thelma planted an herb garden. She planted rosemary in 2/9 of the garden. She
Reptile [31]

Answer:

\dfrac{17}{45}

Step-by-step explanation:

Fraction on which Rosemary was planted =\dfrac{2}{9}

Fraction on which dill was planted =\dfrac{2}{5}

Let the fraction on which chives was planted=x

Then:

\dfrac{2}{9}+\dfrac{2}{5}+x=1\\$Since the LCM of 9 and 5 is 45\\We multiply all through by 45\\45\left(\dfrac{2}{9}\left)+45\left(\dfrac{2}{5}\right)+45x=45(1)$\\10+18+45x=45\\45x=45-28\\45x=17\\Divide both sides by 45\\x=\dfrac{17}{45}

The fraction of the garden on which Chives was planted is \dfrac{17}{45}

I need number 22 PLS AND THANK YOU!
notsponge [240]

Answer:

For any two given points (x1,y1) and (x2,y2), the slope = (y2-y1)/(x2-x1)

Let's take the points (15,3) and (30, 6):

slope = (y2-y1)/(x2-x1)

= (6-3)/(30-15)

=3/15

=1/5 =0.2

The slope, in general, means the rate of change of y, relative to x. In the context of this question, the slope tells us that the amount of concrete that can be poured (in yards) is a fifth of the time taken (in minutes).

Write in standard form. (x+1)(x+1)(x+2)
german

Answer:

x^3 + 4x^2 + 5x + 2.

Step-by-step explanation:

(x+1)(x+1)(x+2) = (x^2 + x + x + 1)(x + 2) = (x^2 + 2x + 1)(x + 2) = x^3 + 2x^2 + 2x^2 + 4x + x + 2 = x^3 + 4x^2 + 5x + 2.

Hope this helps!
