24. Solve the system of equations below: 2x - 6y = - 12 x+2y = 14
how do I do this I don't get it please help​

Answers

Answer 1

Answer:

(x,y) (28/19, -35/19)

hope this helps

Answer 2

Answer:

x = 6, y = 4

Step-by-step explanation:

multiply the equation x + 2y = 14 by two then subtract the equation 2x - 6y = - 12 to eliminate x and solve for y:

×2 => 2x + 4y = 28

     -)   2x - 6y = -12

_________________

                10y = 40

=>                 y = 4

substitute y = 4 to either of the equation 2x - 6y = - 12 OR x + 2y = 14   to solve for x:

=> 2x - 6(4) = -12

=> 2x = 12

=> x = 6

Given f(x)=sin x and g(x)=cos x, show that f(g(pi/2))=0. Show all your steps.

Answers

Answer:

f (g (pi / 2)) = 0

Step-by-step explanation:

We have the following functions:

f (x) = sin x

g (x) = cos x

The first thing we must do in this case is the composition of functions:

f (g (x))

By making the composition we have:

f (g (x)) = sin (cos x)

We evaluate for x = pi / 2:

f (g (pi / 2)) = sin (cos (pi / 2))

f (g (pi / 2)) = sin (0)

f (g (pi / 2)) = 0

The cost of a new car is $16,500. You can Finance the purchase by paying $500 down, and $350 a month for 60 months. What is the amount financed (Cash Price - Down Payment)?

Answers

Answer:

the amount financed is $16,000

Step-by-step explanation:

The computation of the amount financed is shown below:

As we know that

Amount financed = cash price - down payment

= $16,500 - $500

= $16,000

Hence, the amount financed is $16,000

If we deduct the down payment from the cash price so we can get the amount financed

If these cubes are to to be placed so that their respective faces are parallel

dimensions of the box, without tilting any cubes in any directions,

then choice B) can be justified. This leaves spaces (some volume) in the box

not filled by the cubes.

How many whole number of edges of the cubes fit into 4 cm?  

4 / 3 √ 2   must be rounded down to 3.

How many whole number of edges of the cubes fit into 8 cm?  

8 / 3 √ 2   must be rounded down to 6.

How many whole number of edges of the cubes fit into 10 cm?  

10 / 3 √ 2   must be rounded down to 7.

[tex]\sum\limits_{i=1}^{n} c \cdot a_i \ is \ equal \ to \ c = \ c \cdot \sum\limits_{i=1}^{n} a_i[/tex]

[tex]\sum\limits_{i=1}^{n} i^2 \ is \ equal \ to \ a = \dfrac{n \cdot (n + 1) \cdot (2 \cdot n + 1)}{6}[/tex]

Step-by-step explanation:

1) The sum of a series of the cubes of numbers 'i' is given as follows;

Sₙ = n/2 × (1st term + Last term)

∴ Sₙ = n/2 × (1 + n) = n·(n + 1)/2

It can be shown that the sum of a series of the cubes of numbers 'i²' is given as follows;

Sₙ = (n·(n + 1)·(2·n + 1))/6

It can be also be shown that the sum of a series of the cubes of numbers 'i³' is given as follows;

Sₙ = (n·(n + 1)/2)²

Therefore, we have;

[tex]\sum\limits_{i=1}^{n} c \cdot a_i= c \cdot \sum\limits_{i=1}^{n} a_i = c[/tex]

[tex]\sum\limits_{i=1}^{n} i = \dfrac{n \cdot (n + 1)}{2} = b[/tex]

[tex]\sum\limits_{i=1}^{n} c = c \cdot n = d[/tex]

[tex]\sum\limits_{i=1}^{n} i^3 = \left [ \dfrac{n \cdot (n + 1)}{2} \right]^2 = e[/tex]

[tex]\sum\limits_{i=1}^{n} i^2 = \dfrac{n \cdot (n + 1) \cdot (2 \cdot n + 1)}{6} = a[/tex].

Answer:

divide the figure into two parts.

area of triangle = 1/2×base×height

area of triangle = 1/2×3×3

area pf triangle = 4.5 units²

area of square = side²

area of square = 3²

area of square = 9unit²

Answer:

The figure is made up of a square and a triangle.

We will find both of their areas separately and then combining them will give us the required area.

Area of the triangle : ½ × base × height

= ½ × 3 × 3

= ½ × 9

= 4.5 units²

Area of the square : (side)²

= 3²

= 9 units²

Now, required area = (4.5 + 9) units²

= 13.5 units²

Jamie invests money. In the first year it increases to 110% of its original value.
He spends 20% of the profit on a cricket bat and 1/8 of the reminder on a cricket jumper.
He is left with £140 profit. How much did Jamie invest?

Answers

Answer:

£2000

Step-by-step explanation:

Let the money invested be x.

After 1 year, the money is now 110% of x = 1.1x

Original amount of money: x

Profit in 1 year: 0.1x

He spends 20% of the profit on a cricket bat.

0.2 * 0.1x = 0.02x spent on cricket bat

The reminder of the profit is 0.8 * 0.1x = 0.08x

He spends 1/8 * 0.08x on a cricket jumper.

Amount of profit he has:

0.1x - 0.02x - 0.125 * 0.08x

This equals £140

0.1x - 0.02x - 0.125 * 0.08x = 140

0.08x - 0.01x = 140

0.07x = 140

x = 140/0.07

x = 2000
