vovikov84 [41]

Answer:

The slope is m=2.5 $/movie

Step-by-step explanation:

The slope of the graph could be found using any two points (x_{1} ,y_{1} ) y (x_{2} ,y_{2} ) and the equation for slope of a line, which is

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

So, we select the points (12,35) y (22,60), and we replace the values in the equation for slope,

m=\frac{60-35}{22-12}=2.5

And in this case, represents the cost to rent one movie.

strojnjashka [21]

Answer:

Therefore tomatoes\hspace{0.1cm} patch = \frac{3}{8}\hspace{0.1cm}of\hspace{0.1cm} garden

Step-by-step explanation:

i) from the figure shown pumpkins and lettuce seem to make up half of the of the garden

ii) the other half of the garden seems to be tomatoes and cucumber.

iii) tomatoes seems to be 3 times that of cucumber.

iv) therefore we can say that tomatoes would make up three fourths of half of the garden which would equal to three eights of the garden.

tomatoes\hspace{0.1cm} patch = \frac{3}{8}\hspace{0.1cm}of\hspace{0.1cm} garden

Benny gets a job at a law firm with a salary of $70,000 per year after the first year his salary increases to 73,000 over the ne
Ierofanga [76]

Answer:

  b(t) = 70,000 + 3000t . . . . . salary after t years; t∈{0,1,2,3,4,5,6}

Step-by-step explanation:

We can let b(t) represent Benny's salary function with t being the number of completed years at the law firm, an integer. The function's domain includes only the first 6 years at the firm.

Since Benny gets the same raise each year, The function is linear. Its "y-intercept" is Benny's initial salary, and the rate of change is Benny's annual increase:

  b(t) = 70,000 + 3,000t . . . . salary in dollars after t years with the firm

Iteru [2.4K]

answer:

x = 0.80

y = 1.50

step-by-step explanation:

x = cost of tacos

y = cost of burritos

both equations:

3x + 2y = 5.40

2x + 1y = 3.10

             ^

turn this | into this |

                             v

               y = 3.10 - 2x

then add it to the equation :

3x + 2 [ 3.10 - 2x ] = 5.40

3x + 6.2 - 4x = 5.40

-1x = - 0.8

x= 0.80

then add x = 0.80 to the equations to get :

3 [ 0.80 ] + 2y = 5.40

2.4 + 2y = 5.40

2y = 3

y = 1.5
