I’m sure you can do this on a calculator just input 75 + 25/100.

Answer:

$f(x)=(x-1)^2-7$

Step-by-step explanation:

Standard form:

$f(x)=x^2-2x-6$

Vertex form:

$y=(x-h)^2+k$

(h, k) is the vertex

x is the coordinate of the vertex

To find x use the formula:

$x=\frac{-h}{2a}$

$f(x)=x^2-2x-6$

a=1

b=-2

c=-6

Substitute:

$x=\frac{-(-2)}{2(1)}=1$

Substitute x in equation:

$f(x)=1^2-2(1)-6\\f(x)=1-2-6\\f(x)=-7$

h=1

k=-7

Substitute h, and k into the vertex formula:

$f(x)=(x-1)^2-7$

Find the value of x. help

Komok [63]

Answer:

X=62

Step-by-step explanation:

X=62 because the side where x is and where the other degree is, they are congruent. And since you have to add 12 it would have to be 62 to be equal to 74.

I need help with math it’s urgent thanks

Artemon [7]

Answer:

(1, 3)

Step-by-step explanation:

2x + 3y = 11 ------------(i)

-4x + 2y = 2 ------------(ii)

Multiply equation (i) by 2.

(i)*2 4x + 6y = 22

(ii) -4x + 2y = 2 {Now add and x will be eliminated}

8y = 24

y= 24/8

y = 3

Plugin the value of y in equation (i)

2x + 3*3 = 11

2x + 9 = 11

2x = 11-9

2x = 2

x = 2/2

x = 1

Line L is mapped onto the line t by a dilation centered at

STatiana [176]

The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)

Step-by-step explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size

If the equation of a line is ax + by = k is dilated, with center origin and scale factor k, then the equation of the image of the line is kax + kby = kc
The line and its image are parallel
The coordinates of a general point on the image is (kx , ky)

Line L is mapped onto the line T by a dilation centered at the origin and a scale factor of 3.

That means lint T is the image of line L after dilation

∵ The equation of line L is 2x - y = 7

∵ Line L is dilated by scale factor 3 and centered at origin

- That means multiply the equation of line L by 3 to find the

equation of line t

∵ Line T is the image of line L after dilation

∴ The equation of line T is (3)(2x) - (3)(y) = (3)(7)

∴ The equation of line T is 6x - 3y = 21

Very important note:

The equation of line T is the same with equation of line L but multiplied by the scale factor 3 ⇒ L and T are coincide lines (same line)

That means the equation of lines T and L is 2x - y = 7

The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)
