is 60 people per square kilometer. If the region covers 23 square kilometers, what is the population of the region

**Answer: 1380**

**Step-by-step explanation:**

We have been given that population density is the number of people per unit of area.

Therefore, the population of the region would be 1380 people.

Janelle would like to give a party bag to every person who is coming to her party. The cost of the party bag is $7 per person. Write an inequality that describes the number of people P that she can invite if Janelle has No more than $95 dollars to spend on the party bags.

**Answer: **Inequality that describes the number of people P that she can invite if Janelle has No more than $95 dollars to spend on the party bags: **7P ≤ 95 **

**Step-by-step explanation:**

Given: The cost of the party bag is $7 per person.

P represents the number of people that she can invite.

Total cost for P people = ( cost per person) x (P)

=$ 7P (i)

If Janelle has No more than $95 dollars to spend on the party bags.

That means , Total cost ≤ $ 95

From (i)

**7P ≤ 95 , which is the required inequality.**

4. Write the equation of a line that passes through the point (-8, 2) and is parallel to the

line 3x – 2y = 12.

**Answer:**

3x - 2y = - 28

**Step-by-step explanation:**

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x - 2y = 12 ( subtract 3x from both sides )

- 2y = - 3x + 12 ( divide all terms by - 2 )

y = [tex]\frac{3}{2}[/tex] x - 6 ← in slope- intercept form

with slope m = [tex]\frac{3}{2}[/tex]

Parallel lines have equal slopes, thus

y = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

To find c substitute (- 8, 2) into the partial equation

2 = - 12 + c ⇒ c = 2 + 12 = 14

y = [tex]\frac{3}{2}[/tex] x + 14 ← equation in slope- intercept form

Multiply through by 2

2y = 3x + 28 ( subtract 2y from both sides )

0 = 3x - 2y + 28 ( subtract 28 from both sides )

- 28 = 3x - 2y , that is

3x - 2y = - 28 ← equation in standard form

What is the value of p in the equation shown?

3

p =-0.027

**Answer:**

According to the question,

3p=-0.027

By transposing '3' to the RHS, we get

p=0.027/3

= p=-0.009

So in this question p=-0.009

6(x – 1) = 9(x + 2)

Solve

**Answer:**

x=−8

**Step-by-step explanation:**

6(x−1)=9(x+2)

Step 1: Simplify both sides of the equation.

6(x−1)=9(x+2)

(6)(x)+(6)(−1)=(9)(x)+(9)(2)(Distribute)

6x+−6=9x+18

6x−6=9x+18

Step 2: Subtract 9x from both sides.

6x−6−9x=9x+18−9x

−3x−6=18

Step 3: Add 6 to both sides.

−3x−6+6=18+6

−3x=24

Step 4: Divide both sides by -3.

−3x/−3=24/−3

Please help, this is my first time! Here is the question: Maria earned a total of $504 the last two days. She worked 8 hours the first day, 4 hours the second day. How much did Maria earn every hour? Please show how you did it, this is my first time, so please help.

**Answer:**

$42 per hour

**Step-by-step explanation:**

Well,

She got $504 in total

8 + 4 = 12 (the total number of hours worked)

To find out how much she earned per hour you'll need to divide.

$504 ÷ 12

which equals $42

**Answer:**

Maria earned **$42** per hour.

**Step-by-step explanation:**

First, we need to add the *total amount* of hours she worked.

8 + 4 = **12**

Next, we need to divide 504 and 12 to see how much she earned *per hour*.

504 ÷ 12 = **42**.

So, Maria earned **$42 **per hour.

I hope this helps you! Welcome to Brainly. Good luck and have a great day. :)

for the graph of g(x) pictured below, over which of the following intervals is g(x) only decreasing?

Answer:

2. -8 < x < -2

Step-by-step explanation:

The x-values of the line where the line slants downwards before it begins to slant upwards to the right, is the interval at which g(x) is decreasing only.

From the graph, at x = -8, y = -2. When x = -2, y = -5.

Between the intervals of x = -8 and x = -2, g(x) decreased from -2 to -5.

Therefore, the answer is: 2. -8 < x < -2

**Answer:**

2/3

**Step-by-step explanation:**

Answer:

2/3

Step-by-step explanation:

Slope equals rise/run. You find one perfect point (-2,0) and another along the line (1,2)

You count how many units up (rise) from the first point to the second point, and then you go over (run) to the second point. Your rise over your run is your slope.

What is an equation of the line that passes through the points (6,4) and (4,1)

**First, you find the ****slope.**

**This is done by plugging in to the equation y2 - y1 / x2 - x1**

**Let 6 and 4 by x2 and y2 and 4 and 1 be x1 and y1.**

**4-1 / 6-4 = 3/2**

**The slope is 3/2.**

**Now, y = 3/2 x +b**

**To solve for b, plug in a point.**

**I plugged in (6, 4)**

**4 = 3/2(6) + b**

**4 = 9 + b**

**-5 = b**

**So, the equation is y = 3/2 x - 5**

**Hope this helps**

A bus and a truck leave a gas station at the same time and are headed to the same destination. If the bus traveled 110 miles in 2 hours, and the truck traveled 180 miles in 3 hours, who is on pace to reach the destination first?

**Answer:**

The truck is on pace.

**Step-by-step explanation:**

To find which truck will arrive first, you need to find each vehicle's mph. To get the mph of each vehicle you just need to divide the distance by time.

Bus: 110 (miles) ÷ 2 (hours) = 55 (miles per hour)

Truck: 180 (miles) ÷ 3 (hours) = 60 (miles per hour)

When you do this you can see the mph of the bus is < the mph of the truck.

What is the solution to the system of equations?

**Answer:**

(2, - 4 )

**Step-by-step explanation:**

Given the 2 equations

x + 2y = - 6 → (1)

3x + y = 2 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the term in y

- 6x - 2y = - 4 → (3)

Add (1) and (3) term by term to eliminate y

- 5x = - 10 ( divide both sides by - 5 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (1)

2 + 2y = - 6 ( subtract 2 from both sides )

2y = - 8 ( divide both sides by 2 )

y = - 4

Solution is (2, - 4 )

Answer:

X=-2.5

Step-by-step explanation:

point slope form: y-y1 = m(x-x1)

slope formula: m = y2-y1/x2-x1

substitute in for slope formula: -3 -2/0-4 = -5/-4 = 5/4

so the slope is 5/4

now pick any point (i’m using (4,2)) and plug it it in with the slope into point slope form

y-2 = 5/4(x - 4)

now solve

y-2 = 5/4x - 5

y = 5/4x - 3

ANSWER: y = 5/4x -3

slope formula: m = y2-y1/x2-x1
