Which of following is an example of a quadratic inequality?

-Dominant- [34]

Answer:

Step-by-step explanation:

Quadratic inequalities are inequalities involving quadratics.

A is not an inequality.

B is an inequality and we can rewrite B as:

$x^2+x$

So, B is a quadratic inequality, and is the answer.

C is not a quadratic. The x terms are not squared.

Likewise, D is not a quadratic either since no x terms are being squared.

Four interior angles of a pentagon measure 88°, 118°, 132°, and 100°. What is the measure of the fifth interior angle?

bearhunter [10]

Answer:

102 deg

Step-by-step explanation:

The sum of the interior angles of a n-gon

are equal to ( n-2)*180

for a pentagon ( 5-2)(180) = 540

88+118+132+100 + x = 540 x= 102 deg

Consider a circle whose equation is x + y - 2x - 8=0. Which statements are true? Select three options

Mandarinka [93]

Answer:

The standard form of the equation is

${(x - 1)}^{2} + {(y - 0)}^{2} = {3}^{2}$

Step-by-step explanation:

The given circle has equation:

${x}^{2} + {y}^{2} - 2x - 8 = 0$

We regroup similar terms to obtain:

${x}^{2} -2x + {y}^{2} = 8$

We now complete the square to obtain:

${x}^{2} -2x + {( - 1)}^{2} + {y}^{2} = 8 + {( - 1)}^{2}$

${(x - 1)}^{2} + {(y - 0)}^{2} = 9$

${(x - 1)}^{2} + {(y - 0)}^{2} = {3}^{2}$

This is now of the form:

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

which is referred to as the standard form equation of the circle:

Passes through (4,2) perpendicular to y=-2x+3 PLZ HELP!!

Stells [14]

Answer:

coordinates will be (1/2 , -5)

Step-by-step explanation:

when x=4

y= -2(4)+3

y = -8 +3

y = -5

when y=2

2 = - 2x + 3

2-3 = -2x

-1 = -2x

1=2x

x = 1/2
