In solving a two-order linear inequality, say

y>m_1 x and y \ge m_2 x +c

We graph the corresponding linear equations;

\left \{ {{y=m_1 x} \atop {y= m_2 x+c}} \right.

Each of the two equations divides the cartesian plane into half-planes.

By testing for points, we identify the half-plane that satisfies each inequality.

The intersection of the two half-planes gives us a set of points that satisfies the two inequalities simultaneously.

Therefore the solution to the two-order inequality is the intersection of two half-planes.

The correct answer is option C

Based on the information in the table what is the probability of being a girl and choosing lemonade?
tresset_1 [31]

Using it's concept, it is found that the probability of being a girl and choosing lemonade is given by:

b. 0.2.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, out of 130 people, 26 are girls who choose lemonade, hence the probability is given by:

p = 26/130 = 0.2, which means that option b is correct.

What is the formula for finding the perimeter of a quads?
VLD [36.1K]

The formula for finding the perimeter of a quadrilateral is  Length + Length + Width + Width.

<h3>What is Perimeter?</h3>
  • A perimeter is the path that surrounds a certain shape. To calculate the path that surrounds a quadrilateral, we need to get the sum of its four sides, both lengths and widths, lengths being the longest sides and the widths being the shortest.
  • The formula used for calculating perimeter is Perimeter = Length + Length + Width + Width.
  • For instance, to calculate the perimeter of a parallelogram with a side of 5 cm and one of 3 cm, we insert the numbers in their corresponding spot in the formula as such: Perimeter=5+5+3+3=16 cm or since parallelograms have 2 sets of 2 equal sides, we can use this formula Perimeter=(5×2)+(3×2)=10+6=16 cm.
  • For a square on the other hand, we only need to know the length of one side because it has 4 equal sides.

Therefore, the formula for finding the perimeter of a quadrilateral is  Length + Length + Width + Width.

PLEASE HELP ME WITH THIS QUESTION!!!!!!
mr Goodwill [35]

From the table, y varies directly as x. Therefore,  the constant of variation is k = 2 and y = 2x.

<h3>How to find a direct variation?</h3>

For direct variation,

y ∝ x

Therefore,

y = kx

where

  • k = constant of proportionality

Hence,

(-2, -4)

-4 = -2k

k = -4 / -2

k = 2

(-4, -8)

y = -4(2) = -8

Therefore,

k = 2 and y = 2x
