Answer:

Step-by-step explanation:

This is quite a trial and error question.

Given from the table

$1 cost of item = $0.08 tax on item

$2 cost of item = ($0.08x2) tax on item = $0.16 tax on item

$3 cost of item = ($0.08x3) tax on item = $0.24 tax on item

$8.50 cost of item = ($0.08x8.50) tax on item = $0.68 tax on item

$10 cost of item = ($0.08x10) tax on item = $0.80 tax on item

The only one that is different is the incorrect value therefore $0.64 is the incorrect one.

Leto [7]

Answer:

Use the given slope and point to substitute into the point-slope formula y−y1=m(x−x1).

Slope-intercept form:

y=3x²+4x−25

Point-slope form:

y+5=(3x+10)⋅(x−2)

A function f is _____ on an open interval I if, for any choice of x1 and x2 in I, with 1 less than

Zepler [3.9K]

Answer:

If $f(x_1)\leq f(x_2)$ whenever $x_1\leq x_2$ f is <em>increasing</em> on I.

If $f(x_1)\geq f(x_2)$ whenever $x_1\leq x_2$ f is <em>decreasing</em> on I.

Step-by-step explanation:

These are definitions for real-valued functions f:I→R. To help you remember the definitions, you can interpret them in the following way:

When you choose any two numbers $x_1\leq x_2$ on I and compare their image under f, the following can happen.

$f(x_1)\leq f(x_2)$ . Because x2 is bigger than x1, you can think of f also becoming bigger, that is, f is increasing. The bigger the number x2, the bigger f becomes.

$f(x_1)\geq f(x_2)$ . The bigger the number x2, the smaller f becomes so f is "going down", that is, f is decreasing.

Note that this must hold for ALL choices of x1, x2. There exist many functions that are neither increasing nor decreasing, but usually some definition applies for continuous functions on a small enough interval I.

1200+0.075x>=3300 what is the solution to the inequality

miskamm [114]

Solving inequalities is just like solving any other Algebraic problem...look to P.E.M.D.A.S. (Parenthesis, Exponents, Division, Addition, Subtraction). So lets take a look at this problem now.

1200 + 0.075x $\geq$ 3300

Subtract 1200 from both sides...
0.075x $\geq$ 2100

Now divide by 0.075...
x $\geq$ 28000

NOTE: If you divide or multiple by a negative number while solving inequalities, you must flip the sign. Ex: You answer would be x $\leq$ 28000 if you would've multiplied or divided by a negative.
