Answer:

D. 14

make y the subject of the formula in equation 1 and then substitute it in equation 2

Answer:

y=4x+5

Step-by-step explanation:

x= the number of hours

y= total number of money

4x means each hour = 4 dollars

5 = the rent of the shoes

Therefore, y = 4x + 5

Answer:

45.7miles per hour

Step-by-step explanation:

40mins = 2/3 hour

the bus travelled (2/3 x 40) miles = 80/3 miles

the cab took 35 mins (which is 7/12 hour) so it's speed is (80/3)/(7/12) miles/hour = 45.714 miles/hour (5 s.f.)

Answer: [tex]t_n = 4n - 2[/tex]

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

Work Shown:

The first term is a = 2 and the common difference is d = 4, since we're adding 4 to each term to get the next term.

[tex]t_n = \text{nth term of arithmetic sequence}\\\\t_n = a+d(n-1)\\\\t_n = 2 + 4(n-1)\\\\t_n = 2 + 4n - 4\\\\t_n = 4n - 2[/tex]

Which is the answer.

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

If you were to plug in say n = 3, then we get

[tex]t_n = 4n - 2\\\\t_3 = 4(3) - 2\\\\t_3 = 12 - 2\\\\t_3 = 10[/tex]

showing that 10 is the third term, which matches with what the original sequence shows. I'll let you check the other values of n to fully confirm the answer.

Answer:

the slope is -4/3

Step-by-step explanation:

you can either use the graph or algebra to find the slope.

to use the graph, simply count how many spaces up/down and to the left/right that you go.

to use algebra, take the coordinates of your two points and do (y2-y1)/(x2-x1).

Answer:

x : y : z = 9 : 10 : 6

Step-by-step explanation:

Expressing the ratio y : z = 5 : 3 in fractional form, that is

[tex]\frac{y}{z}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )

5z = 3y ( divide both sides by 5 )

z = [tex]\frac{3}{5}[/tex] y = [tex]\frac{3}{5}[/tex] × 10 = 3 × 2 = 6

Thus

x : y : z = 9 : 10 : 6

Answer: 68x + 36y

Step-by-step explanation:

Combine Like Terms:

= 19x + 4y + 49x + 32y

= (19x + 49x) + (4y + 32y)

= 68x + 36y

Hope this helped you!

Answer:

68x + 36y

Step-by-step explanation:

You can compeletely get rid of the parenthesis because it is addition through and thorough.

You have 19x + 4y + 49x + 32y

You can combine like terms to get

19x +49x which is 68x

and

4y + 32y which is 36y

You now have 68 + 36y which cannot be simplified anymore because the variables are different.

Hope this helps!

Answer:

Step-by-step explanation:

  Step one:

Given that membership is $9 and the cost per visit is $1

let the number of visits be x

and the total cost be y

the total cost  for the situation is modeled as

y=mx+c-----equation of a line

   Step two:

given that x=23, we can solve for the totals cost as

by substituting we have

y=1*23+9

y=23+9

y=32

The total cost for 23 visits is $32
