Solving linear-quadratic systems algebraically<br><br> y+2=(x-3)^2<br> y+3=x
Vikentia [17]

Answer:

(2, - 1 ) and (5, 2 )

Step-by-step explanation:

y + 2 = (x - 3)² → (1)

y + 3 = x ( subtract 3 from both sides )

y = x - 3 → (2)

Substitute y = x - 3 into (1)

x - 3 + 2 = (x - 3)² ← expand using FOIL

x - 1 = x² - 6x + 9 ( subtract x - 1 from both sides )

0 = x² - 7x + 10 ← in standard form

0 = (x - 2)(x - 5) ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 5 = 0 ⇒ x = 5

Substitute these values into (2) for corresponding values of y

x = 2 : y = 2 - 3 = - 1 ⇒ (2, - 1 )

x = 5 : y = 5 - 3 = 2 ⇒ (5, 2 )

A trapezoid (also known as a trapezium) is a 4-sided shape with two parallel bases that are different lengths. The formula for the area of a trapezoid is A = ½(b1+b2)h, where b1 and b2 are the lengths of the bases and h is the height. Hope it helps :)

Select the correct answer.

Given:

A function g has the factors (x - 7) and (x + 6).

To find:

The zeros of the function g.

Solution:

We know that if (x-a) is a factor of a function then x=a is a zero of that function because

x-a=0

x=a

It is given that the function g has the factors (x - 7) and (x + 6).

x-7=0

x=7

Similarly,

x+6=0

x=-6

Therefore, -6 and 7 are two zeros of the function g.

Hence the correct option is B.
