what is the slope of the line that passes through (-3,-3) and (-9,5)
The question gives us two points, (-3,-3) and (-9,5), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (5 -(-3)) ÷ (-9 -(-3))
= (5 + 3) ÷ (-9 + 3)
= - ⁴/₃
Checking my answer visually:
Finding the Equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line. Once we have that equation, we can graph it to see if it passes through the two points. If it does, then we calculated the slope correctly.
⇒ y - (-3) = - ⁴/₃ (x - (-3) [ using the point (-3, -3)]
y + 3 = - ⁴/₃ (x + 3)

Answer:
13.896 kg
Step-by-step explanation:
Volume of Gold Bar = Area of [Trapezium x Length of Bar]
Length of Bar = 16 cm
Area of Trapezium = 2 × Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 × 5 × 3 = 7.5 cm²
2 × Area of Triangle = 2 × 7.5 = 15 cm²
Area of Rectangle = 6 × 5 = 30 cm²
Area of Trapezium = 15 + 30 = 45 cm²
Volume of Gold Bar = 45 × 16 = 720 cm³
Density of Gold = 19.3 g/cm³
Mass of Gold Bar = 720 × 19.3 = 13896 g = 13.896 kg
Mass of Gold Bar = 13.896 kg
Therefore the mass of the Gold Bar is: 13.896 kg (kilograms).
Answer:
13.896kg
Step-by-step explanation:
First, find the volume of the trapezium.
Volume = area of cross-sectional area times the length (16cm)
[(a+b)/2] times height
(6+12)/2 x 5
(18/2) x 5
9 x 5
= 45 <-- area of cross section
45 x 16 = 720 cm^3 <-- volume
To find the mass, multiply volume times density
720 x 19.3 = 13 896g = 13.896kg

Answer:
- The graph is decreasing over its entire domain
- The graph is symmetrical about the origin
Step-by-step explanation:
The graph has an unremovable discontinuity at X=0, therefore all continuity answers are incorrect.
The graph is neither symmetrical about the x-axis nor y-axis, but if it were to be rotated around the origin, it would be symmetric.
On both sides of the graph, the slope is decreasing.
Therefore:
- The graph is decreasing over its entire domain
- The graph is symmetrical about the origin
What is the slope of the line that passes through the points (-3, 5) and (1,7)?
01
1/2
02
Answer:
You will use the formula y2-y1 over x2-x1.
This would make 7-5 over 1+3.
7-5=2 and 3+1=4. 2/4=1/2.
The answer is 1/2 :) If it turns out wrong, then the answer is most definitely 2.
A burrito costs $6.50 at a local restaurant.
Choose the table that correctly identifies three points on the graph
Answer:
The bottom left
Step-by-step explanation:
To solve we can create an equation to represent the problem given. In this case, the equation should be linear. This is because the total cost will change by the same amount each time the number of burritos changes. The slope (the amount the cost changes per burrito) is $6.50 because that is how much one burrito costs. So, the function would look like- y=6.5x. Plug in the x-values for the number of burritos and that will give the cost. Once you solve this equation, the bottom left chart is the only one that matches the values.

At an amusement park there's only enough room for 4500 people to be in it at any time. The manager has also worked out that there needs to be 2800 people in the park to make a profit after all the overhead costs and employee pay. If people are entering the park at a rate of 12 people a minute and there are 850 people in the park currently between how many minutes should the door stay open to let guests in?
(a) Translate the scenario above into a compound inequality involving the number of minutes, m, that the door has been open. Take into account both the fact that there must be a minimum of 2800 people and a maximum of 4500 people.
(b) Rewrite the inequality you found in part (a) using the AND connector and then solve the compound inequality.
(c) Write a solution set as a single statement using interval notation.
Using the concept of inequality, the number of minutes which ensures that the park makes profit while also ensuring that the park isn't overcrowded ls expressed below :
m ≤ 304m ≥ 163 (m ≥ 163) AND (m ≤ 304) 163 ≥ m ≤ 304Given the Parameters :
Total capacity = 4500Number of people required in park = 2800Entry rate, r = 12 people per minute Initial capacity, c = 850 Time, m =?The number of minute to keep the gates opened :
c + rm ≤ 4500
850 + 12m ≤ 4500
12m ≤ 4500 - 850
12m ≤ 3650
m ≤ (3650÷ 12)
m ≤ 304.16
Hence, the gates should be left opened for at most 304 minutes
B.)
In other to allow atleast 2800 in for profit sake
850 + 12m ≥ 2800
12m ≥ 2800 - 850
12m ≥ 1950
m ≥ 162.5
The gates should be opened for 163 minutes.
C.)
In other to make profit by allowing atleast 2800 people in while also ensuring that not more than 4500 people are in the park ; the inequality representing the number of minutes the gates should be open is :

Help me decrease 25 by 30%
Step-by-step explanation:
Percentage decrease = 30% × 25
New value = 25 - Percentage decreaseNew value =
25 - Percentage decrease =
25 - (30% × 25) =
25 - 30% × 25 =
(1 - 30%) × 25 =
(100% - 30%) × 25 =
70% × 25 =
70 ÷ 100 × 25 =
70 × 25 ÷ 100 =
1,750 ÷ 100 =
17.5
Absolute change (actual difference) =
New value - 25 =
17.5 - 25 =
- 7.5
Answer:
25 decreased by 30% equals 17.5
Step-by-step explanation:
To solve this, we need to make our equation to solve.
x/25=30/100
We did x because we don't know what 30% of x is. The 25 shows the total, while the right side shows the percent.
Now cross multiply
100x=750
Now divide both sides by 100.
you will get x=7.5
So now we know that 7.5 is 30% of 25. Now, subtract 7.5 from 25 in order to find out what 25 decreased by 30% is.
25-7.5=17.5
So the answer is 17.5

- 0.2 ( 25x + 5 ) - 5 = 4
Answer:
x= -2
Step-by-step explanation:
-0.2(25x+5)-5 = 4
We move all terms to the left:
-0.2(25x+5)-5-(4) = 0
We add all the numbers together, and all the variables
-0.2(25x+5)-9 = 0
We multiply parentheses
-5x-1-9 = 0
We add all the numbers together, and all the variables
-5x-10 = 0
We move all terms containing x to the left, all other terms to the right
-5x= 10
x= 10/-5
x= -2
Answer:
x=-2
Step-by-step explanation:
step 1 -5x-1-5=4
step 2 -5x-6=4
step 3 -5x=10 cause you add 6 on both sides
step 4 and then divide both sides by -5 to get x=-2

We have,
AV = d÷t
80 = d÷2.75
80 × 2.75 = d
d = 220km
Sarah stated that given the following information,
she can prove that the lines 1 and m are not parallel.
Is Sarah correct?
Explain your reasoning.
Answer:
Sarah is correct: lines l and m are not parallel.
Step-by-step explanation:
Given that m < 1 = 130°, and m < 7 = 45°,
Sarah is correct, that lines l and m are not parallel.
If lines l and m were parallel cut by the transversal, n, then its exterior angles < 1 and < 7 that lie on the same side of the transversal should be supplementary. In other words, m < 1 and m < 7 should have a sum of 180°
Since according to the given prompt that m < 1 = 130°, and m < 7 = 45°, the sum of their measure add up to 175°, and not 180°.
Therefore, lines l and m are not parallel.
