Answer:

  see the attachment for a graph

Step-by-step explanation:

We can't tell what your instructions are. Many graphing tools will let you click on the locations of the points, then draw a line through them. The attached image is from one such tool.

__

If you want to plot this by hand, you do it essentially the same way: plot the two points and draw a line through them.

If you want to write an equation for the line, you can start with the 2-point form:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (5 -(-3))/(2 -(-4))(x -(-4)) -3

  y = 8/6(x +4) -3

  y = 4/3x +16/3 -9/3

  y = 4/3x +7/3

__

Personally, about the only thing useful I find in this equation is that it tells you the slope is 4/3. You can determine the same thing by counting grid squares between the plotted points on the graph. The line goes up 8 for each 6 to the right, so slope = rise/run = 8/6 = 4/3.

Answer:

P(t) = 258( 1 + 6%)^t

Step-by-step explanation:

Given that the  population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, the function representing the number of caribou in the forest in t years will be

P(t) = 258( 1 + 6%)^t

Since it is increasing, it will be 1 + 6%

Where P(t) is the function representing the population after t years.

258 is the current or initial population.

Answer: 15.7oz < M < 16.3oz

Step-by-step explanation:

The average mass of each bag will be 16oz

If the bag weighs 0.3 oz more or less than 16 oz, then it is rejected.

Then the extremes are:

16oz - 0.3oz = 15.7oz (this mas counts as a rejected one)

So we have that the mass of the bag must be larger than 15.7oz

M > 15.7oz

Now, the other extreme is:

16oz +0.3oz = 16.3oz (again, this a rejected mass)

Then the mass of the bag must be smaller than 16.3oz

M < 16.3oz

Then the range of the accepted mass of the bags is:

15.7oz < M < 16.3oz

Answer:

Step-by-step explanation:

Since the equation above is a linear graph

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question the equation is

y = 12x - 197

Comparing the equation with the general equation above

Answer:

  -2x^3 +13x^2 +3x -54

Step-by-step explanation:

The product is found using the distributive property.

  (x -6)(-2x^2 +x +9) = x(-2x^2 +x +9) -6(-2x^2 +x +9)

  = -2x^3 +x^2 +9x +12x^2 -6x -54

  = -2x^3 +13x^2 +3x -54

Total amount she earn is $558

Given that;

Payment per hour on weekdays = $15.50

Payment per hour on Sunday = 2($15.50) = $31

Hour work on Sunday = 8 hour

Hour work on weekdays = 20 hour

Find:

Total amount she earn

Computation:

Total amount she earn = (20)(15.50) + (8)(31)

Total amount she earn = $310 + 248

Total amount she earn = $558

Step-by-step explanation:

the square root of of 35 is

5.916079783099616

5.9160797831

Step-by-step explanation:

You can round this to 6 as a whole number or 5.9 to 1dp.

Step-by-step explanation:

x + y = 16 (*)

x^2 + y^2 = 146 (**)

(*) <=> x= 16-y

substitute x = 16 - y

(**) <=> (16-y)^2 + y^2 = 146

<=> y^2 - 2.16.y + 16^2 + y^2 = 146

<=> 2y^2 - 32y + 110 = 0

<=> y^2 - 16y + 55 = 0

<=> (y-11)(y-5) = 0

<=> y=11 or y= 5

For y = 11, we have x= 16-11=5

For y=5, we have x= 16-5=11

Answer: (x,y) = (11,5) ; (5,11)

Answer: If i am correct the answer should be 9-10 because if it is -8 it takes 8 to bring it to 0 and it takes 9 to bring it to 1 and it takes 10 to bring it to 2.

[tex]\huge\boxed{\sf a = \frac{6-3x}{y} }[/tex]

Step-by-step explanation:

3x + ay = 6

Subtracting 3x to both sides

ay = 6 - 3x

Dividing both sides by y

[tex]\sf a = \frac{6-3x}{y}[/tex]

y = -2|x +1|

→ |x + 1| = -y/2

→ x+1 = y/2

and

x + 1 = -y/2

→ x + 1 belongs to R

→ x belongs to R

Domain = R

Range = y = -2(R)

2x+112=180

2x=68

x=34

Let me know if this helps :)

Answer:

34 degrees

Step-by-step explanation:

(2x+9) degrees and 103 degrees  form a linear pair

Therfore, the sum of these two angles = 180

(2x+9)+103=180

=>2x+112=180

=>2x=180-112

=>2x=68

=>x=68/2

=>x=34

The value of x is 34 degrees
