Answer:

The answer is (-1,1)

Step-by-step explanation:

First of all, you can see where the two lines intersect.

Also, if there was no graph, then you could solve by substitution:

1. Substitute y from y = 2x + 3 to -x

2. Then simplify

-x = 2x + 3

subtract 2x from each side

-3x = 3

divide -3 from each side

x = -1

3. To solve for the value of y, you can plug -1 for x and solve.

y = -(-1)

y = 1

Consumer complaints are frequently reported to the Better Business Bureau. Industries with the most complaints to the Better Bus

kiruha [24]

Answer:

(a)

$\begin{array}{ccc}{Industry} & {Frequency} & {\%Frequency} & {Bank} & {26} & {13\%} & {Cable} & {44} & {22\%} & {Car} & {42} & {21\%}& {Cell} & {60} & {30\%} & {Collection} & {28} & {14\%} & {Total} & {200} & {100\%} \ \end{array}$

(b): Cell industry

Step-by-step explanation:

Given (Missing from the question)

$Bank = 26$

$Cable = 44$

$Car = 42$

$Cell = 60$

$Collection = 28$

$Total = 200$

Solving (a) Show the frequency and percent frequency.

The percentage frequency is calculated by:

$\%Freq = \frac{Freq}{Total} * 100\%$

So. we have:

$\%Freq = \frac{26}{200} * 100\% = 13\%$ -- Bank

$\%Freq = \frac{44}{200} * 100\% = 22\%$ --- Cable

$\%Freq = \frac{42}{200} * 100\% = 21\%$ --- Car

$\%Freq = \frac{60}{200} * 100\% = 30\%$ --- Cell

$\%Freq = \frac{28}{200} * 100\% = 14\%$ --- Collection

The table becomes:

Solving (b): The industry with the highest complaints

From the above table, the highest frequency is 60 and this represents the number of complaints of Cell industry.

Hence, the cell industry has the highest number of complaints

Solving (c): Comment

The percentage frequency table shows that the industry with the highest number of complaints is the cell industry (at 30%) and the industry with the least is the banking industry (at 13%)

Nagaraj has a party-length sandwich that is 45 inches long and is to be cut into three pieces. The middle piece will be 3 inche

Sergio039 [100]

Answer:

The length of the shortest piece is 11 inches. The length of the medium piece is 14 inches. The length of the longest piece is 20 inches.

Step-by-step explanation:

Ok, so we have a long sandwich of 45 inches that will be divided in 3, giving us the following formula (x = shortest, y = medium, z=longest):

x + y + z = 45

Then we have middle piece (y) is 3 inches longer than the smallest (x):

y = x + 3

And the shortest piece (x) is 9 inches shorter than the longest (z):

x = z - 9 or z = x + 9

Let's place the found values of y and z in the first equation:

x + y + z = 45

x + (x + 3) + (x + 9) = 45

3x + 12 = 45

3x = 33

x = 11

So, x = 11, y = 14 and z = 20. (11 + 14 + 20 = 45).
