Answer:
B
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:
[tex]x^2+x<0[/tex]
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.

Y = A system of equations. Y equals StartFraction 2 over 3 EndFraction x plus 3. X equals negative 2.X + 3 x = –2
Answer: The solution is the pair (-2, 5/3)
Step-by-step explanation:
The system of equations is:
y = (2/3)*x + 3
x = -2
When we have a system of equations, we usually start by isolating one of the variables in one of the equations and then replacing it in the other ones (in that way, we can "remove" variables, until we have only one and we can solve the problem)
In this case, we have already isolated the variable x in the second equation, then we can just replace it in the first one, to get:
y = (2/3)*(-2) + 3
y = -4/3 + 3 = -4/3 + 9/3 = (-4 + 9)/3 = 5/3
y = 5/3
Then the solution of this system is
x = -2
y = 5/3
Which also can be represented with the ordered pair (-2, 5/3)

The measure, in degrees of an angle that represents 50/360 of a circle is 50 degrees.
What is a circle?A circle is a locus of a point that moves in a plane such that its distance from a fixed point is always constant.
As we know that a circle has a total of 360 degrees all the way around the center.
So, the measure, in degrees of an angle that represents 50/360 of a circle will be = 50/360 * 360 degrees.
the measure, in degrees of an angle that represents 50/360 of a circle will be = 50 degrees.
Therefore, the measure, in degrees of an angle that represents 50/360 of a circle is 50 degrees.

The measure of the angle at the centre of the circle that represents 50/360 of a circle is 50°.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
A complete circle has a 360° angle at the center of it, since the angle we need to calculate is represented by 50/360, therefore, the measure of the angle can be written as,
[tex]\theta = \dfrac{50}{360}\times 360^o = 50^o[/tex]
thus, the measure of the angle at the centre of the circle that represents 50/360 of a circle is 50°.

In order to find the value of x, we can write the following statements and reasons:
Triangle PQR:
1. Statement: PS = PS
Reason: Reflexive property of equality
2. Statement: angle PSQ is congruent to angle PSR
Reason: Given
3. Statement: SQ is equal to SR
Reason: Given:
4. Statement: Triangle PSQ is congruent to triangle PSR
Reason: Case SAS of congruency
5. Statement: PQ is congruent to PR, so PR = 8
Reason: Corresponding sides of congruent triangles
Quadrilateral VSTU:
1. Statement: VT = VT
Reason: Reflexive property of equality
2. Statement: angle SVT is congruent to angle UVT
Reason: Given
3. Statement: angle VST is congruent to angle VUT
Reason: Given
4. Statement: Triangle VST is congruent to triangle VUT
Reason: Case AAS of congruency
5. Statement: ST = TU
Reason: Corresponding sides of congruent triangles
So we have 5z = 2z + 3. Solving for z, we have z = 1, so ST = 5z = 5

Trophies for Gunther's soccer team will cost $6.25 each, plus 15 cents for every word on the engraving. Which equation could be used to find the cost, c, of each trophy based on the number of words, w , on the engraving?
Answer:
Step-by-step explanation:
c = $6.25 + 0.15w
$6.25 represents the fixed cost. it is the cost that does not vary with the number of words
15 cents is the variable cost. it is the cost that varies with the number of words.
to write the equation convert 15 cents to dollars by dividing by 100.
