The two solutions for the system of equations:

y = x^2+ 5x - 3

y - x = 2

Are:

(-5, -7) and (1, -1)

Here we have the following system of equations:

y = x^2+ 5x - 3

y - x = 2

We can replace the first equation into the second one to get:

(x^2+ 5x - 3) - x = 2

x^2 + 4x - 3 = 2

x^2 + 4x - 3 - 2 = 0

x^2 + 4x - 5  = 0

Using the quadratic formula, we will get the solutions:

[tex]x = \frac{-4 \pm \sqrt{4^2 - 4*1*-5} }{2} \\\\x = \frac{-4 \pm 6}{2}[/tex]

The two solutions are:

x = (-4 - 6)/2 = -5

x = (-4 + 6)/2 = 1

To find the values of y, we can evaluate the linear equation:

when x = -5

y - (-5) = -2

y + 5 = -2

y = -2 - 5 = -7

So one solution is (-5, -7)

when x = 1

y - 1 = -2

y = -2 + 1 = -1

The other solution is (1, -1)

The system of linear equations have no solution

The system of linear equations is the set of two or more linear equations involving the same variables. Here, linear equations can be defined as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.

In the problem, given the system of linear equations are

y = 4/5x - 3 ...eq(i)

y = 4/5x + 1 ...eq(ii)

a) Since there are two unknown variables(x, y) the number of solutions expected is 2.

b)

From equation (i)

y = 4/5x - 3

Put eq(i) into equ(ii)

4/5x - 3 = 4/5x + 1

0 = 4

There's no solution for x and y

In the calculation, there's no solution for both x and y because the variables in both equation are equal to one another and hence cancel out.

Using division we know that (D) 2700÷9=300 is the basic fact using which John will get t know how many seeds will be planted in a row.

One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.

The other operations are multiplication, addition, and subtraction.

In mathematics, the division is the process of dividing a number into equal parts and calculating the maximum number of equal parts that may be formed.

For instance, dividing 15 by 3 results in the division of 15 into 3 groups of 5 each.

The division sign, "," or occasionally "/," is used in computer code.

So, we know that: Total seeds are 2700 and the total rows are 9

If there are the same amount of seeds in each row.

Following that, the number of seeds will be put in each row.

= (Total seeds) ÷ (Total rows)

= 2700÷9

= 300

Therefore, using division we know that (D) 2700÷9=300 is the basic fact using which John will get t know how many seeds will be planted in a row.

The probability that a student chosen at random studies physics and chemistry or both is  35/41 = 0.85

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

The formula for probability states that the possibility of an event happening, or P(E), equals the ratio of the number of favorable outcomes to the number of total outcomes. Mathematically, it looks like this: P(E) = favorable outcomes/total outcomes.

The Venn diagram shows:

There are 2 students studying both biology and physics.

Six students study biology and chemistry together.

There are 4 students who study physics and chemistry.

There are 5 students who just study physics.

There are 7 students who just study biology.

There are 8 students who just study chemistry.

There are 6 students that study none.

As a result, there are a total of 41 students, which is equal to 2 + 6 + 4 + 5 + 7 + 8 + 3 + 6 students.

There are 21 students who study chemistry, which is equal to 8 + 6 + 3 + 4 students.

The number of students that studies physics is = 14

The number of students that studies chemistry is =  21

The line parallel to the given line 2x+2y=-12 is also -1.

Define slope.

Slope of a line refers to the measure of the steepness and the direction of a line.

Illustrate y= m x+ c.

y = mx + c refers to an equation of a line having a gradient of m and a y-intercept of c. This equation is often referred to as the slope-intercept form of the equation of a line.

We know that,

The general equation of a line is y=m x+ c,

where m = slope and b = y-intercept, c is a constant

Now, the equation of the given line is,

2x+2y=-12

⇒x + y=-6

Now expressing the equation in the form of y=m x+ c

So, y=-6-x

Further, on rearranging we get y= (-1) x-6

                                                   y = mx + c

So, according to the equation,on comparing we get

m=-1 and c=-6

On comparing, the slope of the given line is -1.

Since, 'The slopes of two parallel line is always equal'.

Thus, the line parallel to the given line is also -1.

The percentage of all graduates who plan to enter the workforce and reside locally is 15%.

According to the tree diagram, we need to calculate the percentage of high school graduates who plan to enter the workforce and reside locally. To calculate this, we need to follow the branches in the tree diagram. Let's start from the top:

1. The first branch shows that 30% of high school graduates plan to enter the workforce.

2. From those 30%, 50% plan to reside locally.

3. To calculate the percentage of all graduates who plan to enter the workforce and reside locally, we need to multiply the percentages from steps 1 and 2 together: 30% * 50% = 0.30 * 0.50 = 0.15 or 15%.

The graph for the linear equation y = -2x + 5 is plotted and shown in the image attached below.

If we are given an equation of a line that is expressed in slope-intercept form as y = mx + b, it means that the graph will have a slope = rise / run = the value of m, while it would cut across the y-axis at b, that is the y-intercept.

Given the equation in slope-intercept form as y = -2x + 5, it means that the graph will have a slope that has a ratio of the rise to the run as -2, while the line will intercept the y-axis at y = 5.
