Answer:

B.In slope-intercept form, the slope is −79.These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is −AB.

Step-by-step explanation:

A is being moved to the other side of the equation so it has to be negative and is multiplied by B since the y value has to be divided to equal the base of y not 9y but y.

What would be the coordinates of triangle A'B'C' if triangle ABC was dilated by a factor of

notsponge [240]

Answer:

$A(0,0)\rightarrow A'(0,0) \\ B(2,0)\rightarrow B'(\frac{2}{3},0) \\ C(0,2)\rightarrow C'(0,\frac{2}{3})$

Step-by-step explanation:

The question is as following:

The verticies of a triangle on the coordinate plane are

A(0, 0), B(2, 0) and C(0, 2).

What would be the coordinates of triangle A'B'C' if triangle ABC was dilated by a factor of 1/3 ?

=============================================

Given: the vertices of a triangle ABC are A(0, 0), B(2, 0) and C(0, 2).

IF the triangle is dilated by a factor of k about the origin, then

(x,y) → (kx , ky)

that triangle ABC was dilated by a factor of 1/3 to create the triangle A'B'C'.

It is given that triangle ABC was dilated by a factor of 1/3 to create the triangle A'B'C'.

If a figure dilated by a factor of 1/3 about the origin

So, $(x,y)\rightarrow (\frac{1}{3}x,\frac{1}{3}y)$

<u>So, The coordinates of the triangle A'B'C' are:</u>

$A(0,0)\rightarrow A'(0,0) \\ B(2,0)\rightarrow B'(\frac{2}{3},0) \\ C(0,2)\rightarrow C'(0,\frac{2}{3})$

Pls help asap!! pic is shown

The points (-5, 1), (-2, 4), (2, 4), and (-5, 1) gives the piecewise defined function as the second option;

g(x) = x + 6, when x < -2

g(x) = x², when -2 ≤ x < 2

g(x) = 6 - x, when x ≥ 2

<h3>How can the correct piecewise defined function be found?</h3>

Parts of the function are:

x < -2

Slope = (4-1)/(-2-(-5)) = 1

Equation is: g(x) - 4 = x - (-2)

g(x) - 4 = x + 2

g(x) = x + 2 + 4 = x + 6

g(x) = x + 6

In the region, -2 ≤ x < 2, points on the graph are;

(-2, 4), (0, 0), (2, 4)

The above points corresponds with the function;

g(x) = x²

In the region x ≥ 2, we have;

Slope = -1

Equation is: g(x) - 4 = -1×(x - 2) = 2 - x

Therefore;

g(x) = 4+2 - x = 6 - x

g(x) = 6 - x

The rule for the piecewise defined function is therefore;

g(x) = x + 6, when x < -2
g(x) = x², when -2 ≤ x < 2
g(x) = 6 - x, when x ≥ 2

The correct option is therefore the second option;

15 * 4 2/3 please help

Elenna [48]

4 2/3 = 14/3

15 = 15/1

14/3 * 15/1 = 14*15=210, 3*1 = 3

210/3 = 70

Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?

Eduardwww [97]

Answer:

2 4/36

Step-by-step explanation:

To do this, multiply the whole number by the denominator and add it to the numerator.

8 x 9 = 72

72 + 4 = 76

76/9

<em>Then multiply across (multiply numerators with numerators; denominators with denominators)</em>

76 x 1 = 76

9 x 4 = 36

76/36 = 2 4/36

____________________________

<em>A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.</em>

1/4 x 8/1 = 8/4 = 2

1/4 x 4/9 = 4/36

= 2 4/36
