(5,-4) translate left 6

Answer:

(-1 , -4)

Step-by-step explanation:

The left & right is controlled by the "x" in the coordinate (x , y). When you translate to the left 6, it means that you subtract 6.

Subtract 6 from the number in the x-coordinate (5):

(5 (-6), -4)

(-1 , -4)

Your new point is (-1 , -4).

Answer:
(-1,-4)

Explanation:
A coordinate is written like (x,y). When you translate left/right, you are moving across the x axis and when you translate up/down, you are moving across the y axis. Using this, we know that translating left 6 would only change the x value.

Translating left 6 means you’re subtracting 6, and 5-6=-1

Therefore, the final coordinate would be (-1,-4)

Find area of the isosceles triangle formed by the vertex and the x-intercepts of parabola y=x2+4x−12.

xz_007 [3.2K]

The area of the isosceles triangle is 64 sq units.

<u>Solution:</u>

Part 1: x-intercepts

The x-intercepts occur at the points on the function where y=0

So, we need to solve

$x^2-4x-12=0$

The left side factors fairly easily into:

$(x-6)(x+2)=0$

So solution occur when

$x-6=0\rightarrow x=6$

and

$x+2=0\rightarrow x=(-2)$

So the x-intercepts are at (0,6) and (0,−2)

Part 2: vertex of the parabola

The vertex of a simple quadratic parabola occurs when the derivative of the quadratic is equal to 0.

The derivative of the given quadratic is

$\frac{dy}{dx}=2x-4$

By observation, this is equal to 0 when x=2

When x=2 the original equation becomes

$y=(2)^2-4(2)-12$

$y=-16$

Therefore the vertex of this parabola is at (2,−16)

The endpoints of the base of the isosceles triangle are (-6, 0) and (2, 0)

$\Rightarrow$ so its base is 8

The height of the triangle reaches from the midpoint of the base (-2, 0) and the vertex (2, -16)

$\Rightarrow$ so its height is 16

The area is $\frac{1}{2}\times \text { base }\times \text { height }=\frac{1}{2}\times8\times16=64 \text{ sq units }$

What is the answer to 5-10x<-145

Nuetrik [128]

Answer:

x > 15

Step-by-step explanation:

So here we have to find the value of x

So, Subtract 5 from both sides;

-10x < -5 - 145

Now collect like terms,

-10x < -150

Divide both sides by -10

x > 15

The sign changes because if an equality is divided by a negative number the sign automatically changes.
