Answer:

The bearing of A from B is 296 degrees

Step-by-step explanation:

Here, we want to find the bearing of point A from point B

To find the bearing of point A from B, we simply subtract the bearing of B from A from 360

Mathematically, that will be;

360 - 64 = 296 degrees

Answer:B

Answer:

It is non linear

Step-by-step explanation:

Linear means that it goes at a constant rate (aka a straight line)

This graph does not have a straight line so it is non-linear

Answer:

x < 7

Step-by-step explanation:

Given

5x - 7 < 28 ( add 7 to both sides )

5x < 35 ( divide both sides by 5 )

x < 7

Answer:

x>7

Step-by-step explanation:

Treat this inequality as a regular equation.

-5x<35

-x<7

x>7

(You switch signs if you divide with a negative btw.)

Answer:

The equation is;

y = 1/2x + 7

Step-by-step explanation:

Here, we want to write in the slope-intercept form, the equation that goes through the two points

The general form of this is;

y = mx + b

where m is slope and b is the y-intercept

we start by calculating the slope of the line

m = (y2-y1)/(x2-x1)

m = (8-6)/(2-(-2))

m = 2/4 = 1/2

So we have ;

y = 1/2x + b

To get b, we use any of the two pints

8 = 1/2(2) + b

8 = 1 + b

b = 8-1

b = 7

Answer:

1) x-intercept= (-6,0) y-intercept= (0,-3)

2) x-int= (2,0)  y-int= (0,-5)

Step-by-step explanation:

Answer:

1) x = 2 and y = -4

2) x = 4 and y = 5

Step-by-step explanation:

to check if it's correct, simply plug in the numbers to the x and y value.

1) 2 + 2(-4)

2 + -8 = -6

(x + 2y = -6)

2) 5(4) - 2(5)  

20 - 10 = 10

(5x - 2y = 10)

Answer:

[tex]x = 155 \frac{1}{13}[/tex] or 155 1/3 degrees. If you want a decimal, 155.076923 degrees.

Step-by-step explanation:

2,016 is the sum of 13 identical numbers. Let's say the unknown number is [tex]x[/tex]. We'll now write an equation to solve it.

[tex]13x = 2016[/tex]

Divide both sides by 13.

[tex]x = \frac{2016}{13}[/tex]

Now, I went ahead and solved this and ended up with a repeating decimal. But for your sake we'll just make it a nice mixed number.

13 goes into 2016 155 times.

Here, I'll check for you.

[tex]13 * 155 = 2015[/tex]

So, if we were to turn this into a mixed number, we'd get something like this.

[tex]x = 155 \frac{1}{13}[/tex]

That should be your fourteenth angle measure.

Answer:

x = [tex]\frac{25}{6}[/tex]

Step-by-step explanation:

Given expression is,

[tex]2x-\frac{11}{4}x=-\frac{25}{8}[/tex]

[tex]\frac{8x}{4}-\frac{11}{4}x=-\frac{25}{8}[/tex]

[tex]\frac{8x-11x}{4}=-\frac{25}{8}[/tex]

[tex]-\frac{3x}{4}=-\frac{25}{8}[/tex]

[tex]\frac{3x}{4}\times 4=\frac{25}{8}\times 4[/tex]

[tex]3x=\frac{25}{2}[/tex]

[tex]\frac{3x}{3}=\frac{25}{2}\times \frac{1}{3}[/tex]

x = [tex]\frac{25}{6}[/tex]

Answer:

24 Tennis balls

Step-by-step explanation:

Calculation for How many tennis balls are left

First step

Since we have 12 can with 3 balls each Let the number of balls that the tennis pro has at the beginning be x

x=(12 can ×3 balls each)

x=36

Second step

Since we have 4 players who lost 3 ball each Let the total number of balls that was lost be y

y=(4 players×3 balls each)

y=12

Third step is to calculate How many tennis balls are left

Since x represent the number of balls at the beginning and y represent the number of balls that was lost , then let the number of tennis balls that was left after the session represent z

z=36−12

z=24 Tennis balls

Therefore the numbers of tennis balls that are left will be 24 Tennis balls

Answer:

y = 2(4^(x))

Step-by-step explanation:

In 2012, the park has a population of 32 lions. A year later, in 2013, the park has 128 lions.

This means in 2012, it was 2^(5) lions while after 1 year it was 2^(7) lions

Thus, it increases every year by a ratio of 2^(2)

Thus, in 2011, it was 2^(5) - 2^(2) = 2^(3) lions

In 2010, it was 2^(3) - 2^(2) = 2

Since Lions were introduced in the park in 2010, using f(x), it means;

at x = 0, f(x) = 2

at x = 1, f(x) = 2^(3)

at x = 2, f(x) = 2^(5)

at x = 3, f(x) = 2^(7)

To find an exponential function that models the situation, let's use the generic formula: y = ab^(x)

At x = 0 and y = 2, we have;

2 = a × b^(0)

Thus,a = 2

At x = 1, y = 2^(3)

Thus; 2^(3) = 2 × b^(1)

b = 8/2

b = 4

So the exponential equation is;

y = 2(4^(x))

You can use the fact that the given figures are expressible as 2 raised to some powers.

The exponential function modeling the number of lions to the years passed since 2010 is given as

[tex]f(x) = 2^{1+2x}[/tex]

Those functions which are expressed as some constant raised to the power of the argument called exponential function.

Since 2012  - 2010 = 2 and the number of lions = 32 = [tex]2^5[/tex]

and 2013 -2010 = 3 and the number of lions =128 = [tex]2^7[/tex]

Thus, there is increment of 2 exponent as 1 year was changed.

Thus, we have:

[tex]f(x) = 2^{2x + a}[/tex] where a might be some constant( i took this form of exponent just by trial and error. It was already visible that one year was increasing double output, thus 2x and since there was just double increase and no other effect, there might be some non variable thing(a constant) so i thought to try some variable and see if this can work)

Since at x = 2, we get 2 raised to the power 5

thus.

[tex]2(2) + a = 5\\a = 1[/tex]

Thus,

The exponential function modeling the number of lions to the years passed since 2010 is given as

[tex]f(x) = 2^{1+2x}[/tex]

You can see that this will give correct output for x = 2 and x = 3

Answer:

27: -5/11

28: 4x^2+12x

29: (2b-7c+5a)(2b-7c-5a)

30: 2/3

Step-by-step explanation:

27 is pretty simple, start by multiplying both sides by 6

so we have 2(6y+1)=y-3

this equal 12y+2=y-3

Subtract 1y and 2 from both sides to get

11y=-5

divide and get y= -5/11

28: this one is a lot to write so if you need me to explain it leave a comment but I got 4x^2+12x

30: For this one I just distributed then combined like terms to get y=2/3

You can see that for every one grid square to the right, the graph moves two grid squares up.  Therefore the slope is 2.

Graphing is pretty easy. Think of the x and y axis as a number line, you go to the right of 0 you get positive. You go to the left, you get negative. The x axis is just that, the y axis is just like a number line but flipped. You go up for positive and down for negative on the y axis. The middle point is always (0,0). To graph a shape, you just connect the points. To plot positive points you would go right and up. So to plot (8,2), you would go 8 points right on the x axis, then 2 points up on the y axis. Think of Quadrant I as 2 positive points, if both points are positive, plot them there. If you need to plot a negative point then a positive point you would go to Quadrant II. If both of the points are negative, plot them in Quadrant III. If it is a positive point then negative, go to Quadrant IV. Remember, the x axis always comes first. Always go right or left first, then up or down. You determine how many points to go right or left then up or down by the point given. Lets take another example. If you were told to plot (-1,5), that would go in Quadrant II. You would go left 1 and up 5. I explained the concept of the coordinate plane, although, I'm not sure what you mean by coordinate proof. Hope that helped :)

Answer:

£120

Step-by-step explanation:

With regards to the above, the difference between the ratio is

3:1 is 2

I.e

(3 - 1) = 2

Nick gets 2 extra, which is equal to £60

Therefore,

1 share = £60/2 = £30

June gets 1 share = 1 × £30 = £30

Nick would get = 3 × £30 = £90

Therefore, the value gotten by both would be;

= £30 + £90

= £120
