The fraction will be undefined on x=5 and x=-5

Step-by-step explanation:

The fraction is undefined on values that make the denominator of the fraction zero.

Given fraction is:

$\frac{5x-10}{x^2-25}$

To find the values on which the denominator will be zero, we put the denominator equal to zero.

$x^2-25=0\\(x)^2-(5)^2=0\\(x+5)(x-5)=0\\x+5 = 0 => x=-5\\x-5 = 0 => x=5$

So,

The fraction will be undefined on x=5 and x=-5

Help!! What is arc HLK? Thankyou!

Bezzdna [24]

We know Angle HMK is half the sum of Arc JI and Arc HLK. So, we can set up an equation.

8x - 1 = 1/2 (3x + 2 + 15x - 36)

8x - 1 = 1/2 (18x - 34)

16x - 2 = 18x - 34

32 = 2x

16 = x

Then, we can substitute x into Arc HLK

HLK = 15x - 36

HLK = 240 - 36

Arc HLK = 204°

Answer:

option: C is correct.

Step-by-step explanation:

since, we are given a parent function f(x) as: f(x)=x.

We are asked to find what change will occur in the function when the parent function f(x) is replaced by f(9x).

let g(x) be the function formed by replacing f(x) with f(9x) i.e.

g(x)=f(9x)=9x.

clearly the slope of the function g(x)=f(9x) is 9. ( since on comparing the equation with the slope intercept form y=mx+c; where m is the slope of the line and c is the y- intercept).

whereas the slope of the function f(x)=x is 1.

Hence there is an increment of slope by a factor of 9.

Hence, option C is correct.

The volume of a rectangular solid can be written as V=LWH, where L is the length of the solid, W is the width, and H is the heig

marshall27 [118]

Answer:

The length of the rectangle is 9 inches.

The height of the rectangle is 11 inches.

Step-by-step explanation:

Given : The volume of a rectangular solid can be written as V=LWH, where L is the length of the solid, W is the width, and H is the height. A box of cereal has a width of 2 inches. It’s height is 2 inches longer than it’s length. If the volume of the box is 198 cubic inches.

To find : What are the length and height of the box ?

Solution :

The width of the box is L inches

The width of the box is W=2 inches

The height is 2 inches longer than it’s length i.e H=L+2

The volume of a rectangular solid is $V=L\times W\times H$
