Answer:
-2x-6y= -14 (i)
-6x-2y= -26 (ii)
Multiply eq (i) by 3
-6x-18y= -42 (iii)
-6x-2y= -26 (ii)
Subtract eq (iii) from ii
-6x -18y = -42
+6x+2y = +26
_______________
0 - 16y = -16
●y= 1
Put y =1 in eq 1
-2x -6 (1) = -14
-2x = -14 + 6
-2x = -8
●x =4

A ship leaves a port and travels 21km on a bearing of 32 and then 45km on a bearing of 287 calculate its distance from the port and the bearing of the port from the ship
Answer:
44.5 km on a bearing of 134.1°
Step-by-step explanation:
A suitable vector calculator will tell you the location of the ship from port is ...
21∠32° +45∠287° = 44.5∠-45.9°
The bearing of the port is in the reverse direction, so 180° added to this:
180° +(-45.9°) = 134.1°
The distance from port is 44.5 km. The bearing of the port is 134.1°.
_____
Additional comment
The distance from port is perhaps most easily found using the Law of Cosines. It is the third side of a triangle with sides 21 and 45. The included angle is (287° -(180° +32°)) = 75°. The distance is then ...
c = √(a² +b² -2ab·cos(C)) = √(21² +45² -2·21·45·cos(75°)) ≈ √1976.83
≈ 44.5 km
The angle between the 32° bearing and the bearing from the port to the ship can be found using the Law of Sines.
B = arcsin(b/c·sin(C)) = arcsin(45/44.5sin(75°)) ≈ 77.9°
so, the bearing angle from the ship to the port is ...
180° +(32° -77.9°) = 134.1°
__
Bearings are measured clockwise from north. A diagram can be helpful.

9514 1404 393
Answer:
D. -17%
Step-by-step explanation:
The change from March to April is (April - March) = (100 -120) = -20. As a fraction of the March bill, that is ...
-20/120 = -1/6
As a percentage, that change is ...
-1/6 × 100% ≈ -16.667% ≈ -17%
The electric bill changed by about -17% from March to April.
_____
Additional comment
Water went up 4%; groceries went up about 14%, and restaurant changed by -15%.
The percentage change is found by ...
% change = ((new amount)/(original amount) -1) × 100%
Above, we have rearranged this to ...
% change = ((new amount) -(original amount))/(original amount) × 100%

determine the measurement of segment XV
Answer:
Segment XV is equal to 24 mm
Step-by-step explanation:
Both triangles are clearly congruent, both having the same type of angles as well as angle LKJ and angle VKW having the same angle measure, 21 degrees. Lastly, if you were to take out segment JL and WV, the triangles would fold the same. All of this leads to segment XV being the same as segment KL which leads it to be 24 mm. (Sorry if this is confusing, just trying to explain how my brain understood the problem. If you need me to elaborate more let me know).
Write an equation for the line in the given form.
Contains the points (5, 2) and (8, 11); slope-intercept form
Answer:
y = 3x-13
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= ( 11-2)/(8-5)
= 9/3
=3
Then using slope intercept form
y= mx+b
Using one of the points and the slope
2 = 3(5) +b
2 = 15 +b
2-15 = b
-13 =b
y = 3x-13

How do you Find cross products with multiplication?
I will give 500 pts and Brainliest!
Answer:
A cross product is an form from an vector multiplication, performed in between for two vectors from a different kinds or nature. An vector may have both magnitude also direction. So we can multiply two or more vectors for crossing a product also a dot product. The resultant vector is an perpendicular to a plane having the two add vectors.

Describe how the graph of y= 2x is the same and different from the graph of y=2x+8
Answer:
They are the same because they have the same slope, 2. and they are different because they different y-intercepts, 0 and 8.
Step-by-step explanation:
Your equations y=mx+b
m is your slope, both 2 and
b is your y-intercept, 0 for your first one because it doesn't have any, and 8 for your second one.

divide £64 in the ratio 3:5
Answer:
64/1 . 5/3
320/3
106.666666?
Answer:
£24 and £40
Step-by-step explanation:
To divide into the ratio of 3:5, we can start by dividing into 8 parts - as 3+5=8, then do 3 parts and 5 parts to achieve the ratio.
£64 / 8 = £8
3 * £8 = £24
5 * £8 = £40

Suppose that $2000 is placed in an account that pays 2% interest compounded each year. Assume that no withdrawals are made from the account.
The amount in the account after 1 year is $2,040.00
The amount in the account after 2 years is $2,080.80
What is future value of a single cash flow?
The future value of a single cash flow like the $2,000 is the future equivalent worth of the initial amount when interest earned is added to it.
The future value in this case can be determined as shown thus:
FV=PV*(1+r)^N
FV=unknown future value
PV=initial investment=$2000
r=interest rate=2%
N=years of investment , 1 and 2 years respectively
FV after one year:
FV=$2000*(1+2%)^1
FV=$2,040.00
FV after two years:
FV=$2000*(1+2%)^2
FV=$2,080.80

What is an equation of the line that passes through the points (-6, -2) and
(-3, 2)?
Answer:
y = (4/3)x - 2/3
Step-by-step explanation:
From (-6, -2) to (-3, 2) we see the x-component changing by 3 units and the y-component by 4 units. Thus, the slope of this new line is
m = rise / run = 4/3.
Let's focus on the point (-3, 2). Here x = -3 and y = 2. Plugging these three values into the slope-intercept form of the equation of a line, we get:
2 = (4/3)(2) + b.
Then 2 = 8/3 + b, or 6/3 = 8/3 + b. Thus, b = 6/3 - 8/3, or -2/3.
The equation of the desired line is y = (4/3)x - 2/3
Answer:y=4/3x+6
Step-by-step explanation:

What is the point slope and slope intercept of this graph below
Answer:
Line is y = -3x + 3
Slope = -3
y-intercept = 3
Step-by-step explanation:
Slope is the movement up or down, and left or right. Y-intercept is the point in which the line crosses the y-axis. In slope-intercept form (y=mx+b), m represents the slope, while b represents the y-intercept.
So since the line crosses the y-axis at positive 3, that will be the y-intercept. Now if we go from that very same point, and do rise/run, we'd move downwards 3 units and to the right 1 unit, to get our slope of -3/1 (it's written as just -3 though).
So now we plug it in: y = -3x + 3
