Draw the image of △ABC under a dilation whose center is P and scale factor is 1/2
Vesna [10]

Answer:

Step-by-step explanation:

Let the point P is at the origin (0, 0).

Then the coordinates of A, B and C will be (8, 4), (-2, 2) and (4, -4) respectively.

Rule for the dilation of a point by a scale factor = k

(x, y) → (kx, ky)

If k = \frac{1}{2}

Then, A(8, 4) → A'(4, 2)

          B(-2, 2) → B'(-1, 1)

         C(4, -4) → C'(2, -2)

Now we can plot the new image with points A', B' and C'

1.  x/6>3  multiply both sides by 6

x>18

So a. and c. are both greater than 18

2.  

-4x<32  divide both sides by -4  (and remember to reverse direction of inequality sign because of multiplication/division by a negative value!)

x>-8

So three value of this infinite set are -7, -6,  -5  :P

3.

x/6≥3 multiply both sides by 6

x≥18

So three value of this infinite set of solutions are 18,19,20

What is the equation, in slope-intercept form, of the line with a slope of -1/3 and y-intercept of (0, 9)? Choices in picture be
Pie

Step-by-step explanation:

The formula is<em> y=mx+b</em>, with <em>m</em> representing the slope, <em>x</em> representing the <em>x </em>coordinate, and<em> b</em> representing the y-intercept. Since -⅓ is the slope, that means that the equation starts off as y=-⅓. We know that the y-intercept is where the line meets the y-axis, so the y-intercept is 9. Since 9 (the y-intercept) is being added, that means the equation is y=-⅓+9.

Answer:

y=-⅓+9
