What is the solution to the system of equations?

Mathematics
2 answers:
Shalnov [3]3 years ago
6 0

Answer:

(-2 , 3)

Step-by-step explanation:

Let the linear system of equations be represented by the linear equations:

y = mx + c

where m = gradient

            c = y-intercept

from the graph, the intersection of the lines represents the solution of the equation.

In this case, the point of inter section takes place at (-2 , 3)

solving the linear equations gives x = -2 and y = 3 which gives the same answer.

What is the solution for −40 = 10c? <br> A. c = 1 <br> B. C = -1 <br> C. c = -4 <br> D. c = 4
Aleks [24]

Answer:

C. c = -4

Step-by-step explanation:

you must get c by itself. you have to divide both sides by 10. this gets rid of the 10c and keeps both sides equal

-40/10 = c

c = -4

12. Write the first five terms of two different sequences that have 10 as the
kodGreya [7K]

Answer:

a)  The arithmetic sequence with common difference 2 that has 8 as the first term.

b) The arithmetic sequence of common difference -5 and first term 15.

Step-by-step explanation:

Let's use for example the arithmetic sequence with common difference 2 that has 8 as the first term. Then the first two terms of this sequence are:

8, and (8+2) = 10 Therefore the second term is 10.

Another arithmetic sequence of common difference -5 and first term 15. The firs two terms of this sequence are:

15, and  (15 - 5)  = 10. Therefore again a 10 as second term.
