The amount of money saved by Andre in 40 weeks is $1280.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis of the given problem.

Given is Andre saves up the same amount of money each week.

We can write the equation, equating the total amount of money saved and the number of weeks as follows. Assume the equation to be -

y = mx + c

Then -

m = (288 - 224)/(9 - 7)

m = 64/2

m = 32

Now -

y = 32x + c

For the point (7, 224), we can write -

224 = 32 x 7 + c

c = 0

For {x} = 48, we can write the amount of money saved as -

y = 32 x 40

y = 1280

Therefore, the amount of money saved by Andre in 40 weeks is $1280.

(0.818  , 1.546)  is the point that is part of solution.

point (0,2) and (2,0) are not the part of solutions.

3y - 2x ≤ 3

y + 3x  ≤ 4

these are the system of inequalities.

What are Inequalities?

Inequality is a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.

Given in this question,

There are two lines L1 and L2.

From the graph we can find the two points that lies on the line L1 be

(0,1) and (3,3).

similarly From the graph we can find the two points that lies on the line L2 be

(0,4) and (2,-2).

From the two points (x1 , y1) and (x2,y2) we can write the equation of the Line from the following formula :

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex].   This is the equation of line for given two points.

Equation of line L1 :

[tex]y-1=\frac{3-1}{3-0} (x-0)[/tex]

3y - 3 = 2x ----------(ii)

Equation of line L1 : 3y - 2x = 3.

Equation of line L2 :

[tex]y-4=\frac{-2-4}{2-0} (x-0)[/tex]

y   = -3x + 4 ----------(ii)

Equation of line L2 : y + 3x = 4.

The point that is the part of the solution :

putting the value of y from equation (ii) in equation (i).

3(-3x+4) -3 = 2x

-9x-2x = -12+3

-11x = -9

  x = 0.818

y = -3(0.818) +4 = +1.546

so Point of intersection is (0.818  , 1.546)

This is the point that is part of solution.

The point that is not below both the lines are not part of solution.

the point that are not part of solution are:

3y - 2x ≥ 3  ->  (0,2)

y + 3x  ≥ 4   ->  (2,0)

point (0,2) and (2,0) are not the part of solutions.

Inequalities are for shaded portion :

3y - 2x ≤ 3

y + 3x  ≤ 4

A scatter plot which represents relationship between the time (in hours) and height (in meters) has been plotted in the image attached below.

In this scenario, the time (in hours) would be plotted on the x-axis (x-coordinate) of the scatter plot while the height (in meters) would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

From the scatter plot (see attachment) which models the relationship between the time (in hours) and height (in meters), a linear equation for the line of best fit is given by

y = -0.29x + 0.52

In conclusion, we can reasonably infer and logically deduce that the scatter plot indicates an inverse relationship between the time (in hours) and height (in meters).

The value of function f(x), when x=2.4 is f(x)=0.00625.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

If the function f(x) varies inversely with x, then this function is of the form -

f(x)=a/x

where a is unknown number.

Since  f(x)=0.5 when x =0.3, then -

0.5 = a/0.3

a = 0.5 × 0.3

a = 0.15

So, the function now becomes -

f(x) = 0.15/x

Substituting for x = 2.4 -

f(2.4) = 0.15 / 2.4

= 15/240

= 1/16

= 0.00625

Therefore, f(x) value is obtained as 0.00625.

d. x les-than-or-equal-to 3 Graph B

Graph B expressed as follows; The graph on the coordinate plane, a line goes through (0, 3) and (4, 5). Another line goes through (1, 0.5), and (4, 6.5). The lines intersect at (3, 4.5)

Step-by-step explanation:

The given inequality is expressed as follows;

0.5·x + 3 ≥ 2·x - 1.5

Let y₁ = 0.5·x + 3, and y₂ = 2·x - 1.5, we get;

For x = -1, 0, 1, 2, 3, 4, 5, 6

y₁ = 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6

y₂ = -3.5, -1.5, 0.5, 2.5, 4.5, 6.5, 8.5, 10.5

From the given data, the lines intersect at (3, 4.5)

The graph on the coordinate plane, a line goes through (0, 3) and (4, 5). Another line goes through (1, 0.5), and (4, 6.5). The lines intersect at (3, 4.5)

Please find attached the required inequality created with MS Excel

Therefore, we have;

3 + 1.5 ≥ 2·x - 0.5·x

4.5 ≥ 1.5·x

∴ 3 ≥ x

x ≤ 3

Therefore, with (typographical) correction, the best option is x les-than-or-equal-to 3 Graph B

The probability the coin comes up all heads or all tails after 4 tosses is 1/8

The value of the odds is given as

Odds = 1 : 7

Represent the odds as a fraction

So, we have the following representation

Odds = 1/7

To convert the odds to probability, we make use of the following equation

Probability = Odds/(1 + Odds)

Substitute the known values in the above equation, so, we have the following representation

Probability = (1/7)/(1/7 + 1)

Evaluate the sum

Probability = (1/7)/(8/7)

Evaluate the quotient

Probability = 1/8

Hence, the probability is 1/8

Answer:

4382 contains 4 significant figures, 4382 round to 1 significant figure is 4000.

Answer:

1) b   2) b

Step-by-step explanation:

1) Both expressions have (x+6). Rearrange them and you'll have one expression as (x+6) and the other as (5ab-4).

2) (4b - 7x)(a + b) factors to be 4ba + 8b - 7ax - 14x, which can be rearranged to 4ab - 7ax + 8b - 14x

Question 1

---------------------

Explanation:

Note how we have (x+6) show up twice. What we can do is erase both copies to end up with 5ab-4. Then stick parenthesis around that to get (5ab-4). Effectively what is going on here is that we're pulling out the GCF (x+6).

Lastly, tack on the (x+6) we erased earlier to get the factorization of (5ab-4)(x+6). Because multiplication can be done in any order, this means it's the same as (x + 6)(5ab - 4)

We can use the distribution method, the box method, or FOIL to expand that factorization back out and help confirm we have the correct answer.

===========================================================

Question 2

---------------------

Explanation:

We'll use the factor by grouping method.

Pair up the terms, then factor each grouping pair. From there, you'll follow the ideas mentioned in problem 1 to finish things off.

This is what the steps could look like:

4ab - 7ax + 8b - 14x

(4ab - 7ax) + (8b - 14x) ... pair up terms

a(4b - 7x) + 2(4b - 7x) ... factor out GCF from each group

(a + 2)(4b - 7x) ... use the trick done in problem 1

(4b - 7x)(a + 2) .... the order of multiplication doesn't matter

You can use the distribution method, FOIL method, or box method to help confirm the answer.
