O (10,4)
O (4, 10)
The value of the solution to the system of equations are, (10, - 20)
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
System of equations are,
y = -5x + 30 .. (i)
x = 10
Now, We can find the solution as;
Plug x = 10 in equation (i);
y = - 5x + 30
y = - 5 × 10 + 30
y = - 50 + 30
y = - 20
Thus, The value of the solution to the system of equations are, (10, - 20)

You can solve the quadratic equation using the quadratic formula. For the system of three equations, use basic algebra according to the given condition. The equation involving sum of products can be solved by performing individual multiplications and then calculating the sum.
To help you understand and solve these mathematical equations, let's break them down. For the
quadratic equation
4.90t² + 20t +c = 0, you can use the quadratic formula to find the values of t. It's important to note here that the quadratic formula is [-b ± sqrt(b² - 4ac)] / (2a).
Also, given the system of three equations and three unknowns (Qd, Qs, and P), you can solve these using basic algebra. With Qd = Qs you can set the demand and supply equations equal to each other: 16 - 2P = 2 + 5P. You can then rearrange and solve for P.
Lastly, you have an equation where calculation of the sum of the products is involved: 1(.35) + 2(.20) + 3(.15) + 4(.15) + 5(.10) + 6(.05) = 2.6 years. This means that each number is multiplied by the corresponding percentage and then all results are added up.
