A quadratic equation is shown below:x2 − 8x + 13 = 0

Add 3 to both sides of the equation

Add 5 to both sides of the equation

Subtract 3 from both sides of the equation

Answers

The given quadratic equation can be represented in the form $(x-p)^2 = q$

by adding 3 to both sides of the equation.

What is a quadratic equation?

The polynomial equation whose highest degree is two is called a quadratic equation. The equation is given by

$ax^2 + bx + c = 0$

where $a\neq 0$ .

The given quadratic equation is

$x^2 - 8x + 13 = 0$

Case 1: Subtract 5 from both sides of the equation

i.e. $x^2 - 8x + 13 - 5 = 0 - 5$

⇒ $x^2 - 8x + 8 = -5$

The LHS of the above equation can not be expressed in $(x-p)^2$ form. Hence, it is not the correct step.

Case 2: Add 3 to both sides of the equation.

i.e. $x^2 - 8x + 13 +3 = 0 + 3$

⇒ $x^2 - 8x + 16 = 3$

⇒ $x^2 - 2* x * 4 + (4)^2 =3$

⇒ $(x - 4)^2 = 3$

The above equation is expressed in $(x-p)^2 = q$ form where p = 4 and q = 3.

Case 3: Add 5 to both sides of the equation

i.e. $x^2 - 8x + 13 + 5 = 0+5$

⇒ $x^2 - 8x + 18 = 5$

The LHS of the above equation can not be expressed in the $(x-p)^2$ . Hence, it is not the correct step.

Case 4: Subtract 3 from both sides of the equation

i.e. $x^2 - 8x + 13 - 3 = 0-3$

⇒ $x^2 - 8x + 10 = -3$

The LHS of the above equation can not be expressed in the $(x-p)^2$ . Hence, it is not the correct step.

Hence, "Add 3 to both sides of the equation" is the correct step.

Add 3 to both sides, so you will have

x^2 - 8x + 13 + 3 = 3
x^2 -8x + 16 = 3

And now the left side is a perfect square trinolmial: (x-4)^2.

The coordinates of A, B,and C in the diagram are A(p,4), B(6,1), C(9,q). What equation correctly relates p and q?

Answers

I don't see any diagram. So, I'll just wing it.

Value of q:
p, 6, 9 ⇒ there is a difference of 3. The sequence increases by 3. So, it can be assumed that the p is equal to 3. A(p,4) ⇒ A(3,4)

Value of q:
4, 1, q ⇒ there is a difference of 3. The sequence decreases by 3. So, it can be assumed that q is equal to -2. C(9,-2)

p q
A 3 4 ⇒ 3 + 4 = 7
B 6 1 ⇒ 6 + 1 = 7
C 9 -2 ⇒ 9 + (-2) = 7

Notice that the sequence has an equation of p + q = 7.

Given: f(x)=4x-9 and g(x)= 2x-3. What is the value of (f+g)(0)=?A.-9
B.-10
C.-11
D.-12

Answers

Answer:

D. -12

Step-by-step explanation:

if f=4x-9, and g=2x-3, and the value is (f+g), then we have to add the equations. This is equal to 6x-12. And then, in '(f+g)(0)', it is asking what is the y-value at x=0. Plug in 0 into the equation, and the y-value equals -12.

1: An isosceles triangle XYZ has an equal side XY and XZ of length 16 cm. Of the third side YZ is 20 cm, calculate the altitude the triangle Leave Answer in surd form

Answers

Answer:

2√39 cm

Step-by-step explanation:

ΔXYZ is an isosceles triangle & XY = XZ, therefore:

YX' = X'Z

= 20 ÷ 2

= 10 cm

ΔXYZ' is a right triangle, therefore:

XY² = YX'² + XX'²

16² = 10² + XX'²

XX'² = 256 - 100

XX' = √156

= 2√39 cm

2x-17x+15=0 solve for x

Answers

Answer:

x=1

Step-by-step explanation:

2x-17x+15=0

Combine like terms

-15x +15 = 0

Add 15x to each side

-15x+15x+15=0+15x

15 = 15x

Divide by 15

15/15 = 15x/15

1 =x

Answer:

x=1

Step-by-step explanation:

x=1 because you need to isolate the variable by dividing each side factors that don't have a variable.
