The process of solving the 3 variable with 2 equation is explained below.

The term equation is defined as a relationship between two terms on either side of an equal sign.

Here we have the following steps to solve the 3 variable for two equation is solved accordingly.

First of all we have to take any two equations and solve it for one variable.

And then again we have to take another two pair of equations and solve for the same variable.

Now, we have a system of two equations with two unknown variables.

Then we have to solve the equation by using the appropriate arithmetic operations.

The length of ST is 16 units.

A line segment is a part of line having two endpoints and it is bounded by two distinct end points and contain every point on the line that is between its endpoint.

We have to given that;

Point P is the midpoint of ST.

SP = x + 4, and ST = 4x

Since, P is the midpoint of ST.

Hence, We get;

⇒ SP = PT

And, ST = 2 SP

Substitute all values we get;

⇒ 4x = 2 (x + 4)

⇒ 4x = 2x + 8

⇒ 4x - 2x = 8

⇒ 2x = 8

⇒ x = 4

Thus, The value of ST = 4x

                                  = 4×4

Using trigonometric ratios, the value of x is as follows:

A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the angle of a right angle triangle can be found using trigonometric ratios as follows:

Hence, let's find angle x

Therefore,

sin x = opposite / hypotenuse

opposite side = 7 ft

hypotenuse side = 18 ft

Hence,

sin x = 7 / 18

x = sin⁻¹ 7 / 18

Answer:

(f/g)x = (x - 3)/(2x - 3)

Step-by-step explanation:

Try and see if f(x) can be factored.

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

That means that perhaps f(x) has one of these two factors.

(2x   3)(x   3)

You want the 2x and 3 to multiply. The middle term has to be -, so when 2x and 3 multiply likely it is 3 that gives you the minus answer.

(2x + 3)(x - 3) should be the way f(x) factors, and it is.

f(x) / g(x) = (2x + 3) (x - 3)

                 (2x + 3)(2x - 3)

2x + 3 cancels. The answer is

(f/g)x = (x - 3)/(2x - 3)

The linear equation for jj is ($7.46 - $2.66) / 5 and the cost of each bottle of juice is $0.96.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                                   Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

The first step to take in order to determine jj, is to determine the total cost of the  5-pack of juice bottles.

Cost of the  5-pack of juice bottles = Total cost before tax - cost of the bag of oranges

Cost of the  5-pack of juice bottles = $7.46 - $2.66 = $4.80

The second step is to determine the cost of each bottle of juice

The cost of each bottle of juice = Cost of the  5-pack of juice bottles / total number of bottles

$4.80 / 5

= $0.96

Answer:

[tex]-3/\sqrt{58}[/tex]

Step-by-step explanation:

tan = opposite / adjacent

opposite side is the y-coordinate of a point on the terminal side

adjacent side is the x-coordinate of a point on the terminal side

if the terminal side is in the second quadrant (the top-left quadrant), a coordinate on the terminal side would have a negative x-coordinate and a positive y-coordinate

This being the case:

the opposite side (y) would be -3 and the adjacent side (x) would be 7

using the Pythagorean theorem:

[tex]a^2+b^2=c^2[/tex]

[tex]7^2+(-3)^2=c^2[/tex]

The hypotenuse is c, so it equals [tex]\sqrt{58}[/tex]

sin = opposite / hypotenuse

The real thing is to do 46000 x 1.15, because on the 3rd year, your salary will be 115% of your salary, if that makes sense, you do 5x3 = 15, then you add 15% to 100 which is 115 % =1.15. then you do 46000x1.15= 55545$

Carlos accepts a new job with a starting salary of $46,000. He will earn a 5% increase after each year. What will be his salary after 3 years.

It is defined as the fee you pay to borrow money or the fee you levy to lend money. Interest is considerable and frequently recalled as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

Incorrect solution,
$46,000 • 1.05 • 3 = $144,900 is Carlos’ salary after 3 years.

Correct solution,
Principal amount = $46,000
rate of increase in salary each year = 5%
After t = 3 years what will be the salary = ?

following identity is used to calculate the increments in principal amount.
[tex]Amount = principal(1+r)^t[/tex]

[tex]Amount = 46000(1+0.05)^3\\Amount = 46000(1.05)^3\\[/tex]

For the provide inquilty problem,

a) The feasible region lies in between the following equations,

b) The extreme points of feasible region are (2,5) , (6,1) ,(0,0),(6,0),(0,5).

Let consider, x = A and y = B, this changes your inequalities and equations as follows: Maximize x + 2y, such that:

x ≤ 6

y ≤ 5

2x + 2y = 14

x,y ≥ 0

We use graphical method, for getting the solution of problem. So, first change the Inequalities into equality equations.

we would then find the region of feasibility by looking at the areas on the graph that satisfy the inequalities and equations,

x ≤ 6

y ≤ 5

2x + 2y = 14 (this is an equation)

x ≥0

y ≥ 0

a) The graph will look like as present above : we can see that the feasible region is the area on the graph that is:

on or below the line y = 5

on or to the left of the line x = 6

on or above the line y-axis , y = 0

on or to the right of the x-axis, x = 0

on the line 2x + 2y = 14

This says is that your solution has to be on the line of 2x + 2y = 14, have an x-coordinate that is greater than or equal to 0 and less than or equal to 5 and have a y-coordinate that is greater than or equal to 0 and less than or equal to 5. The maximum or minimum value should be at the corner points of the feasible region.

b) The corner points would be at (x,y) = (2,5) and (x,y) = (6,1). Also, plotted some other points on the line just to show the max/min value of function on the corner points of the feasible region.

(2,5) = 12

(4,3)= 10

(3,4) = 11

(6,1) = 8

the maximum solution is at the coordinate of (2,5) and all of your constraints have to be satisfied at the this point. The solution is that the maximum value is when x = 2 and y = 5, that is one of the corner points of the feasible region.

The sales tax rate on the item = 8%

We know that the sales tax is nothing but the purchase price times the percentage of tax.

An item costs $430 before tax.

This means, the purchase price is 430 dollars.

The sales tax is $34. 40

To find: the sales tax rate as a percentage

First we find a ratio of the sales tax to the cost of the items before tax.

Sales tax / Pre-tax value of item = (34.40) / 430

Now we write a proportion where the pre-tax value is proportional to 100% and solve for the percentage of sales tax.

i.e., (34.40) / 430 = sales tax percent / 100

So, the sales tax percent  = 8%

Therefore, the sales tax is of 8%
