Answer:

a = -8

Step-by-step explanation:

4a - 7 = 5a + 1

<em>subtract 1 from both sides of the equation</em>

4a - 7 - 1 = 5a + 1 - 1

4a - 7 - 1 = 5a

4a - 8 = 5a

<em>subtract 4a from both sides of the equation</em>

4a - 4a - 8 = 5a - 4a

-8 = 5a - 4a

-8 = 1a

-8 = a

The unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.

<h3>How to Find the Unit Rate of a Proportional Graph?</h3>

The unit rate of a proportional graph is determined using the formula below:

k = y/x, where x and y are coordinates of any point on the line.

Thus, to find the unit rate of a proportional graph, pick the coordinates of any point on the line and find k = y/x.

From the given graph, let's pick the indicated point on the line having the coordinates, (12,16). Find k:

Unit rate (k) = 16/12

Simplify

Unit rate (k) = 4/3

Therefore, the unit rate that corresponds to the proportional relationship shown in the given graph above is: 4/3 cm/s.

Which expression represents the number of possible combinations of n items taken rat a time
Likurg_2 [28]

Answer:

nCr =  n! / (r!)(n-r!).

Step-by-step explanation:

That would be nCr =  n! / (r!)(n-r!).

A quick way of working these out is as follows:

Take 7C4:

this  is  7*6*5*4/4*3*2*1   Cancelling out the 4 and 3*2:

=  7*5

= 35.

15C12 = 15C(15-12)

= 15C3

= 15*14*13 / 3*2*1

=  5*7*13

= 455.

Bobby finds that the experimental probability that he will make a hole-in-one on any hole of a miniature golf course is 10%. If
rodikova [14]

<u>Answer:</u>

Bobby could make into 5 holes out of 50 holes in miniature golf .

<u>Step-by-step explanation:</u>

Bobby has experimental probability that he will make a hole-in-one on any hole of a miniature golf course is 10%, i.e. If there is a miniature golf of 100 holes bobby could make into 10 goals. Probability is<em> 10%</em> i.e.<em> 1/10</em>

According to question,  Bobby plays 50 holes of miniature golf :

No. of goals he could make = ( No. of holes ) × probability<em>⇒ 50× (1/10) </em>

∴ No. of goals he could make <em>⇒</em><em> 5</em>
