Can anyone explain the basics of solving systems to linear equations?

Len [333]

Answer:

A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane. ... The lines intersect at infinitely many points.

Reuben learned in art class that a mosaic is made by arranging small pieces of colored material such as glass or tile to create

anastassius [24]

Pattern is the rule that guides the formation of a set.

The sequence of the first five mosaics is 5, 8, 11, 14, 17
The sequence is arithmetic
There are 32 tiles in the tenth mosaic.

From the given design, the number of tiles used is:

$T_1 = 5$

$T_2 = 8$

$T_3 = 11$

(a) The first five

Notice that the difference in the number of tiles of successive mosaic is 3.

This means that:

$T_4 = T_3 + 3 = 11 +3 = 14$

$T_5 = T_4 + 3 = 14 +3 = 17$

So, the sequence of the first five mosaics is 5, 8, 11, 14, 17

(b) The type of sequence

The sequence is arithmetic

This is so, because the difference in the number of tiles of successive mosaic is 3.

This difference is called the common difference

(c) The number of tiles in the tenth mosaic

The nth term of an arithmetic sequence is:

$T_n = T_1 + (n - 1) \times d$

In this case:

$T_1 = 5$

$d =3$

$n = 10$

So, we have:

$T_{10} = 5 + (10 - 1) \times 3$

$T_{10} = 5 + 9 \times 3$

$T_{10} = 5 + 27$

$T_{10} = 32$

There are 32 tiles in the tenth mosaic.

F(x) = -4x + 15 g(x) = 7x^3 Find (f-g)(2)

djyliett [7]

$(f-g)(2)=f(2)-g(2)$

Therefore, find f(2) and g(2) first before subtracting.

$f(x)=-4x+15$

Therefore,

$f(2)=-4(2)+15\\f(2)=-8+15\\f(2)=7$

Then find g(2)

$g(x)=7x^3\\g(2)=7(2)^3\\g(2)=7(8)\\g(2)=56$

Then put f(2) to subtract g(2)

$f(2)-g(2)=7-56\\f(2)-g(2)=-49$

Therefore, the answer is (f-g)(2) = -49.
