Answer:
(x,y) (28/19, -35/19)
hope this helps
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

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)?
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
And, the same would be considered

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?
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
Answer: £2000

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

Answer:
Region B & C
Step-by-step explanation:
Usually, in inequality graphs, the solutions are usually located in the shaded region of the graph.
Also, we make the boundary line thick if the points on that line also contain solutions to the inequality.
In this question, the boundary line of function g(x) is thick and the shaded region is B and C.

AS:
If these cubes are to to be placed so that their respective faces are parallel
or perpendicular, as the case may be, to the respective orientations of the
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.
Then (3)(6)(7) = 126

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.
Given f(x)=sin x and g(x)=cos x, show that f(g(pi/2))=0. Show all your steps.
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
what's the volume of this composite figure
a. 272 cubic inches
b. 192 cubic inches
c. 180 cubic inches
d. 372 cubic inches
please help!! I'll give brainiest
Answer:
372 in³
Step-by-step explanation:
v1 = 12×4×4=192 in³
v2 = 12×3×5=180 in³
total volume =180 +192 =372 in³

[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].
