Answer:

The required expression is 0.85p.

Step-by-step explanation:

Consider the provided information.

Let the original price is p.

Now it is given that we need to write an expression that the original price p of an item less a 15% discount.

15% of p can be written as:

\frac{15}{100}\times p

0.15\times p

0.15p

The original price p of an item less a 15% discount.

This can be written as:

p-0.15p = 0.85p

Hence, the required expression is 0.85p.

The function f ( x ) = x ^3 + 2x^2− 5 x − 6 has a root at 2. Name all roots of this function.
Tomtit [17]

sub x=1 into f(x),

remainder= 1^3+2(1)^2-5(1)-6= -8

since remainder≠0, x=1 is not a root of the function

sub x=-1,

remainder = (-1)^3+2(-1)^2-5(-1)-6= 0

by remainder theorem,

x=-1 is a root of f(x)

hence, the correct ans is c

Which expressions can be used to compute the approximate area of triangle XYZ? Check all that apply.
lesantik [10]

Given:

In the given ΔXYZ,

Base = 22

Height = 23.1

Also,

Base = 31.9

Height = 15.9

To find the area of the given ΔXYZ.

Formula

The area of a triangle is

A = \frac{1}{2} bh

where, b be the base and

h be the height.

Now,

Taking, b = 22 and h = 23.1 we get,

A = \frac{1}{2} (22)(23.1) sq unit

Again,

Taking,

b = 31.9 and h = 15.9 we get,

A = \frac{1}{2} (31.9)(15.9) sq unit

Therefore,

We can find the approximate area of the triangle by following two expression

a) \frac{1}{2} (22)(23.1) and

b) \frac{1}{2} (31.9)(15.9)

A tour director collected $258 for 13 tour packages. tour package a costs $18 and tour package b cost $22. how many of each tour
valkas [14]
A + b = 13
22 a + 18 b = 258
------------------------
a = 13 - b
22 * ( 13 - b ) + 18 b = 258
286 - 22 b + 18 b = 258
- 4 b = 258 - 286
- 4 b = - 28
b = ( - 28 ) : ( - 8 ) = 7
a = 13 - 7 = 6
Answer:
6 tour packages a and 7 tour packages b were sold.
