4x + 19 = 26 - 3x
<u>+3x               +3x</u>
7x + 19 = 26
<u>       -19  -19</u>
        <u>7x</u> = <u>7</u>

Before ordering food for a company barbecue the president took a poll. She asked people if they would eat the ribs, hamburgers,
Vinvika [58]

Answer:

The complete question is as shown in the attached figure 1

The Venn diagram is the attached figure 2

Let: R⇒ribs , H⇒hamburgers  and  C⇒corn

People would eat all three = 53

People would eat only R and H = 56 - 53 = 3

People would eat only C and H = 54 - 53 = 1

People would eat only R and C = 55 - 53 = 2

People would eat only H = 60 - (53+3+1) = 60 - 57 = 3

People would eat only R = 59 - (53+3+2) = 59 - 58 = 1

People would eat only C = 56 - (53+1+2) = 0

See Vinn diagram.

=========================================================

a. How many people did not want any of these foods?

people did not want any of these foods = 64 - (53+3+1+2+3+1) = 1

b. How many people would eat ribs but not corn?

people would eat ribs but not corn = 1+3 = 4

c. How many people would eat something as long as it was not a hamburger?

people would eat something as long as it was not a hamburger= 1+2 = 3

d. How many people would eat only corn?

people would eat only corn = 0

e. How many people would eat exactly two foods?

people would eat exactly two foods = 1 + 2 + 1

A taxi company charges $1.00 for the first mile (or part of a mile) and 20 cents for each succeeding tenth of a mile (or part).
meriva

Step-by-step explanation:

solving functions separately.

1st:  from given data taxi charges $1.00 for the first mile.so it is first rule of function.

y_{1} =1 , 0

2nd: the company charge $0.20 per tenth of a mile.so 2nd rule of the function will  be

y_{2} =1+0.2.10(x-1)

simplifying

y_{2} =1+2(x-1)

y_{2} =x+2x-2

y_{2} =x ,  1

piece wise function is f(x)={2 ,  0<x<1

                                              {x ,  1<x<2

the graph of the function is given below

Please help n show work
notsponge [240]

x = time in minutes

y = distance remaining

Steve starts at home when the time is x = 0 minutes. The y value y = 40 pairs up with this x value. This is shown by the point (0,40) on the diagonal line, aka the y intercept. The y intercept is where the line crosses the y axis.

The y = 40 indicates that Steve has 40 miles remaining when he starts at home. In other words, the distance from home to work is 40 miles.

The x intercept is where the diagonal line crosses or touches the x axis. The x intercept is (45,0) which represents the idea that 45 minutes have passed by. The y = 0 means that he has 0 miles left go to. Steve has reached the office at this point.

-----------------------------------------------

Answers:

Steve's office is located 40 miles from home

It takes him 45 minutes to travel this distance
