Point C (6,-2) is dilated from the origin by scale factor r= 1/2 What are the coordinates of C?

Mathematics

Ilya [14]2 years ago

Answer:

The coordinates of point C after dilation will be: (3,-1)

Step-by-step explanation:

Dilation in the coordinate plane can be defined as enlargement. There are different types of dilation. The most simple one is dilation from origin.

A factor is used to dilate a point from the origin. For example, if (x,y) is a point and a is the scale factor then the coordinates of points will be:

(x,y) => (ax,ay)

Given point is:

C(6,-2)

r = 1/2

The new coordinates of point C will be:

C(6,-2) => C'(\frac{1}{2}(6) , \frac{1}{2}(-2)) => (3,-1)

The coordinates of point C after dilation will be: (3,-1)

Please I need help!!!
Valentin [98]

Answer:

Solution given:

for second

we have

f(x)=x²-9x-36

let

y=x²-9x-36

when

x=0

y=-36

when

y=0

0=x²-9x-36

x²-12x+3x-36=0

x(x-12)+3(x-12)=0

(x-12)(x+3)=0

either

x=12

x=-3

So,

x and y intercepts are (-3,0)(12,0) and 0,-36)

X^{2} - 8x + 7 = 0<br> Solve by completing the square. Also can you include steps?
iren [92.7K]

Answer:

{1, 7}

Step-by-step explanation:

Start with x^2 - 8x + 7 = 0.

We want to modify the first two terms to resemble x^2 - ax + b - b, where a is the coefficient (here -8) of the x term and b is the square of half of a.

Here, a = -8.  Half of that is -4.  The square of -4 is 16, and this is the value of b.

Write out x^2 - 8x     as    x^2 - 8x + 16 - 16.  This is the perfect square of -4, added to x^2 - 8x and then subtracted from the result

Then the original equation, x^2 - 8x + 7 = 0, can be rewritten as:

x^2 - 8x + 16 - 16 + 7 = 0, and then as (x - 4)^2 - 9, or (x - 4)^2 = 9.

We want to solve this result for x.  To do this, take the square root of both sides:

x - 4 = ±√9, or x - 4 = ±3.

Adding 4 to both sides, we get:

x = 4 ± 3.  Thus, the solutions are x = 4 + 3 = 7 and x = 4 - 3 = 1.
