The solution for the system of equation is 4534 and the graphical representation is attached below.

A system of equation or simultaneous equations are a pair of linear equation is 2 variables such that they represent a pair of straight line sin the cartesian plane.

The point of intersection of these two line on the cartesian plane is given by the solution of the two equation that are given.

A system of equations can be solved algebraically  by matrix method , elimination method or by substitution.

Now let us solve the given equation algebraically by elimination method.

5x - y = 35

3x + y = -3

Adding the equation we get:

or, 8 x = 32

or,  x  = 4

putting the value of x in the first equation we get:

5 × 4 - y = 35

or, -y = 35 - 20

or, y = -15

Hence the point of intersection is ( 4 , -15 )

Combine 7a and −a to get 6a.

6a=3

Divide both sides by 6.

a= 63

Answer:

3y = 5x - 24

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

3y = 5x + 2 ( divide through by 3 )

y = [tex]\frac{5}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{5}{3}[/tex] x + c ← is the partial equation of the parallel line

to find c substitute (6, 2 ) into the partial equation

2 = 10 + c ⇒ c = 2 - 10 = - 8

y = [tex]\frac{5}{3}[/tex] x - 8 ← equation in slope- intercept form

multiply through by 3 to clear the fraction

3y = 5x - 24 ← equation of parallel line

Step-by-step explanation:

When Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime then the total amount he earned is $232.2

Given,

The amount he earns in an hour = $5.40

Total number of hours he worked =40 hours

The amount he earns = 5.40×40 = $216

Overtime hours = 2 hours

Overtime payment per hour= 5.40×1.5= $8.1

The amount he earns for overtime = 2×8.1= $16.2

The total amount he earned = 216+16.2= $232.2

Hence, when Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime then the total amount he earned is $232.2

We need to know about the concept of compound interest to solve the given problem. The minimum interest rate that Harry needs to meet his need is 11.4%

Compound interest can be described as the interest that you earn on both the principal amount and the interest earned. In this question it is said that the bank offers annual interest compounded monthly, we will be using a formula to solve this problem. Since Harry has 21350 EUR we will take that as the principal amount and the minimum amount that he needs is 30000 EUR we will consider this to be the final amount at the end of 3 years. We need to find out the rate of interest that the bank offers.

A=P[tex](1+\frac{r}{12} )^{12t}[/tex] where A is amount, P is principal, r is the rate of interest and t is time period.

P=21350 EUR

A=30000 EUR

t=3

30000=21350[tex](1+\frac{r}{12}) ^{36}[/tex]

[tex]\frac{600}{427} =(1+\frac{r}{12}) ^{36}[/tex]

1+[tex]\frac{r}{12}[/tex]=1.00949

r/12=0.00949

r=0.1139

r=11.4%

Therefore we found that the minimum rate of interest Harry requires to meet his needs is 11.4%

a) for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

In this question, we have been given two functions.

We need to find the given function.

a) f(x) = 8x and g(x) = 12x + 3

To find (f g)(x)

We know that, the product of functions f(x) and g(x) is:

(f g)(x) = f(x) . g(x)

(f g)(x) = (8x) (12x + 3)

(f g)(x) = 96x² + 24x

So, for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) f(x)= 14 and g(x)= 3 - 12x

To find f(x) • g(x)

f(x) • g(x) = (14) . (3 - 12x)

f(x) • g(x) = 42 - 168x

So, for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

Therefore, a) for given functions f(x) = 8x and g(x) = 12x + 3,

(f g)(x) = 96x² + 24x

b) for functions f(x)= 14 and g(x)= 3 - 12x,

f(x) • g(x) = 42 - 168x

The fact that the sum of the interior angles of a triangle add up to 180 is equivalent to the parallel postulate. Therefore, the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry.

There is only one parallel to the given line in Riemannian geometry. A straight line of finite length that can be continued endlessly is the second postulate of Euclid.

One of the non-Euclidean geometries that entirely rejects the validity of Euclid's fifth postulate and alters his second postulate is Riemannian geometry, commonly known as elliptic geometry. The fifth postulate of Euclid states that there is only one line that passes through a point that is not on a particular line and is parallel to that line.

In this case, the angles won't change as it's always equal
