Here, “p” is a numerator and “q” is a denominator. The examples of rational numbers are 6/5, 10/7, and so on. The rational number is represented using the letter “Q”. Like real numbers, the arithmetic operations, such as addition, subtraction, multiplication, and division are applicable to the rational numbers.

Solve the following system of equations by linear combination: 5x 2y = 14 y = x – 7

natta225 [31]

I would use subsitution
y=x-7
sub x-7 for every x
5x+2(x-7)=14
5x+2x-14=14
add 14 to both sides
7x=28
divide both sides by 7
x=4
sub
y=x-7
y=4-7
y=-3

x=4
y=-3
(4,-3)

Find the minimum point of y=5+3x-x^2 Show working out if u can plz

RoseWind [281]

This will be a maximum point as the coefficient of x^2 is negative.
y' = -2x + 3 = 0

x = 1.5

y = 5 + 3(1.5) - 1.5^2 = 7.25

required point is (1.5,7.25)
