Answer:

Mei is correct because -9 is to the left of -3 on the number line.

Step-by-step explanation:

This is because -9 is LESS than -3, when you add or subtract using negative numbers, such as 7-9, you get -2. However when you subtract 7-13, you get -6. Because you subtracted a greater number from 7, your answer is -6 is LESS than -2. This is the same with inequalities, greater negative numbers will always be smaller and smaller negative numbers will always be greater.

Step-by-step explanation:

The region that represents the solution to the system of two inequalities would be Region A.

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Since x≥0 and y≥0 at every point in the shaded region in the first quadrant represent a solution of the given system of inequalities

Since, the system of two inequalities are strict then in graph lines drawn is dotted line as point on line does not includes in the inequality.

The region that represents the solution to the system of two inequalities would be Region A; because the shaded regions are not required.

The true statement about the continuity of f(x) at x=−3 is (c) lim x -> -3 f(x) ≠ f(-3)

The graph represents the given parameter

Answer: -1

Step-by-step explanation:

    We will find the answer to this question by isolating the x variable.

    Given:

2(3x – 1) ≥ 4x – 6

    Distribute the 2 with multiplication:

6x – 2 ≥ 4x – 6

    Add 2 to both sides of the equation, and subtract 4x from both sides of the equation:

2x ≥ – 4

The line perpendicular to YX that passes through the point (3,-8) is (y = − x + 5).

Step-by-step explanation:

It is given that a line perpendicular to YX passes through the point (3,-8).​

Now,

The slope of the line perpendicular to the line YX is 1.

=> y = x

So, Slope = 1

Furthermore, the slope of the required line can be written as -1.

So, the required line can be written in slope-intercept form as;

=>  y = − x + c

It is further given that the line passes through the point (3,2);

So, after putting all the value in the above-mentioned equation, we get;

=> 2 = − 3 + c

=> c = 5

So, x + y = 5

Therefore, the line perpendicular to YX that passes through the point (3,-8) is (y = − x + 5).

The line perpendicular to YX that passes through the point (3,-8) is (y = − x + 5).

In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. It can be defined between two lines, between a line and a plane, and between two planes.

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.

It is given that a line perpendicular to YX passes through the point (3,-8).​

Now,

The slope of the line perpendicular to the line YX is 1.

=> y = x

So, Slope = 1

Further more, the slope of the required line can be written as -1.

So, the required line can be written in slope-intercept form as;

The number of toppings where the cost of each pizza would be equal is 5.

The first step is to formulate an equation that represents the cost of each type of pizza.

Total cost = price of cheese pizza + (price per topping x number of toppings)

Cost of pizza A = $10 + $1.50t

Cost of pizza B = $12.50 + t

When the cost of both pizzas are equal, the above equations would be equal to each other.

$10 + $1.50t = $12.50 + t

To determine the value of t, take the following steps:

Combine similar terms: 1.50t - t = $12.50 - $10

Add similar terms = 0.50t = 2,50

Divide both sides by 0.50 = t = 2.50 / 0.50

The equation of line can be written as, y = 2/3x + 2

Given,

The points, (x, y) = (-3, 0)

Slope = 2/3

Equation of a line, y = mx + c

Where, m is the slope and c is the y-intercept.

Here, m is 2/3.

The point at the x-intercept has co-ordinates : (-3, 0)

Where, x is -3 and y is 0.

So, substitute the values in equation:

y = mx + c

0 = 2/3 × (-3) + c

0 = -2 + c

c = 2
