Answer:
The value of A in the given graph of the equation is 1
That is A=1
Step-by-step explanation:
Given graph of the equation is Ax+2y=-2
Given that the equation of line Ax+2y=-2 passes through the point (2,-2)
Let (x,y) br the point (2,-2)
Therefore we have that
A(2)+2(-2)=-2
2A-4=-2
2A-4+2=-2+2
2A-2=0
2A=2
[tex]A=\frac{2}{2}[/tex]

Therefore the value of A in the given graph of the equation is 1
How can we re-write the expression below into “friendlier” terms? 6 ∙ 29
options:
6 ∙ (30 - 1)
6 ∙ (16 + 13)
6 ∙ (19 + 10)
6 ∙ (21 + 8)
Option A: 6 ∙ (30 - 1)
Solution:
Given expression is 6 · 29.
Friendlier term means a number can be expressed using other numbers which are closest to the number.
Option A: 6 ∙ (30 - 1)
30 is closest to 29, so which is the friendlier term to 29.
6 · 29 = 6 ∙ (30 - 1)
Option B: 6 ∙ (16 + 13)
16 and 13 are not closest to 29, which are not the friendlier terms.
Option C: 6 ∙ (19 + 10)
19 and 10 are not closest to 29, which are not the friendlier terms.
Option D: 6 ∙ (21 + 8)
21 and 8 are not closest to 29, which are not the friendlier terms.
Hence Option A: 6 ∙ (30 - 1) is the correct answer.

jess walked for 45 min at 3km/h and then ran for half an hour at xkm/h. at the end of the time she was 6 km from starting point. find the x value?
Hey there! :)
~ They give us some good information in this equation. Let's use it! This can be used to change "45 min" into ".75 hours".
~ Now, let's write an equation; "distance = speed * time."
~ 3(.75) + .5x = 6
~ 2.25 + .5x = 6
~ .5x = 6 - 2.25
~ .5x = 3.75
~ x = 3.75/.5
~ x = 7.5 km/hr
Final answer:
To find Jess's running speed, the total distances she walked and ran are calculated and added to equal the given total distance of 6 km. Solving the equation 6 km = 2.25 km + 0.5x km reveals that Jess ran at 7.5 km/h.
Explanation:
To find the value of x, which represents Jess's running speed, we can use the information provided to set up equations based on the distance formula: distance = speed × time.
Jess walked for 45 minutes at 3 km/h. First, convert 45 minutes to hours by dividing by 60: 45 minutes / 60 minutes/hour = 0.75 hours. The distance walked is:
Distance walked = Speed × Time = 3 km/h × 0.75 hours = 2.25 km.
Next, Jess ran for 30 minutes or 0.5 hours at x km/h. The running distance is:
Distance ran = Speed × Time = x km/h × 0.5 hours = 0.5x km.
According to the question, the total distance from the starting point after both activities is 6 km, so:
Total distance = Distance walked + Distance ran
6 km = 2.25 km + 0.5x km
Now, solve for x:
6 km - 2.25 km = 0.5x
3.75 km = 0.5x
x = 3.75 km / 0.5
x = 7.5 km/h
Therefore, Jess ran at 7.5 km/h.

3. Divide both sides by 16 and x = -1.
Find an equation of the line passing through the point ( 6 , − 4 ) (6,-4) and perpendicular to 9 x − 3 y = 9 9x-3y=9 . Write your answer in slope-intercept form.
Answer:
[tex]y =-\frac{1}{3}-2[/tex]
Step-by-step explanation:
We are given;
A point (6, -4)An equation of a line, 9x - 3y = 9We are required to determine the equation a line passing through a point (6, -4) and perpendicular to the given line;
To answer the question we need to get the gradient of the given line first.We write the equation 9x - 3y = 9 in the form of y = mx + c, where m is the slope;That is;y = 3x -3
Thus, the slope of the line is 3But; m₁ × m₂ = -1 (For perpendicular lines)
Therefore;
m₂ = -1 ÷ 3
= -1/3
Therefore, the slope of the line in question is -1/3 and the line passes through (6, -4).
To get its equation, we get another point (x, y)
Then;

What is the question that you are asking?
Step-by-step explanation:
what is the sum of two numbers is 40 and their difference is 10
Answer:
The two numbers are 25 and 15.
Step-by-step explanation:
Let's find out the two numbers, this way:
x = first number
y = second number
This is the equations system:
x + y = 40
x - y = 10
Solving for x in the first equation:
x + y = 40
x = 40 - y
Solving for y in the second equation:
40 - y - y = 10
40 - 2y = 10
-2y = 10 - 40
-2y = - 30
y = -30/-2 = 15
Solving for x:
x + y = 40
x + 15 = 40
x = 40 - 15
x = 25
The two numbers are 25 and 15.

352.83 in expanded notation
We can extend 352.83 and write as (3 x 100) + (5 x 10) + (2 x 1) + (8/10) + (3/100)
Step-by-step explanation:
Considering the given value 352.83 we can expand that step by step as,
(3 x 100) which will give us a value of 300.
Now adding the multiplied answer of (5 x 10) will give us 350.
Next we can also add the multiplied answer of (2 x 1 ) which will further give us 352.
Now adding the divided answer of (8/10) we will get 352.08
Finally adding the divided answer of (3/100) we will get the exact value of 352.83 as mentioned above.
The expanded notation for the number [tex]352.83[/tex] is [tex](3\times 100)+(5\times 10)+(2\times 1)+(8\times \dfrac{1}{10})+(3\times \dfrac{1}{100})[/tex]
A number can always be written in the expanded notation by multiplying the face value with the face notation.
Here, [tex]3[/tex] is at the [tex]100th[/tex] place of the number so, it can be written as [tex]3\times 100[/tex].
Similarly, the digits which are located after the decimal point can be expanded by dividing the face value of the number by [tex]10[/tex] raised to the power of face notation.
Here, [tex]8[/tex] is present just after the decimal point and so, its expanded form is [tex]8\times \dfrac{1}{10}[/tex].
Hence, the expanded notation of [tex]352.83[/tex] is [tex](3\times 100)+(5\times 10)+(2\times 1)+(8\times \dfrac{1}{10})+(3\times \dfrac{1}{100})[/tex].

A house is worth 125,000 when it is 2 years old and 135,150 when it is 7 years old. According to this model, how much will the house be worth when it is 16 years old
Final answer:
The house will be worth $153,420 when it is 16 years old, calculated by finding the annual increase in value from the given data and projecting this increase over the relevant time period.
Explanation:
To calculate the worth of the house when it is 16 years old, we need to establish the rate at which the house's value is increasing over time, based on the information given for its value at 2 years and at 7 years. The house is valued at $125,000 when it is 2 years old and $135,150 when it is 7 years old, showing an increase of $10,150 over 5 years.
First, we find the annual increase in value by dividing the total increase by the number of years:
Annual increase = $10,150 / 5 = $2,030.
Next, we predict the value when the house is 16 years old by multiplying the annual increase by the number of years from the starting point (2 years old) to 16 years old:
14 years (from year 2 to year 16) × $2,030 annual increase = $28,420 increase since year 2.
Finally, we add this increase to the original value at year 2:
Projected Value at Year 16 = $125,000 + $28,420 = $153,420.
Hence, according to the model, the house will be worth $153,420 when it is 16 years old.

Tina has 18 sunflower seeds in 15 Daisy seeds she wants to distribute them equally into pots then planting them with no seeds left over what is the greatest number of pots Tina can use
Answer:11
Step-by-step explanation:
Add 18 and 15 then find the GCF
The maximum number of pots she can make is 15.
What is subtraction?The process of subtracting one number from another is known as subtraction.
Given that, Tina has 18 sunflower seeds and 15 daisy seeds.
Since Tina wants to distribute the sunflower seeds and daisy seeds equally in each pot, each pot must contain at least one daisy seed and one sunflower seed.
Therefore, if, she has 1 daisy seed and 1 sunflower seed in each pot, then she can make 15 pots, as there are only 15 daisy seeds.
Now, there are only 3 sunflower seeds left but she cannot use them to make a pot as there are no daisy seeds.
Hence, the maximum number of pots she can make is 15.

The Carter family just left the local pet store with Rex, their new family dog. The pet store owner told the Carter family that for the next 6 months, Rex would grow at an average rate of 9 pounds per month. Currently, Rex is 2 months old and weighs 6 pounds.
Age, in months 2 3 4 5 6 7 8
Weight, in pounds 6
Part A: Complete the given table that represents Rex’s current weight, in pounds, as a function of his age, in months
Part B: Graph the data in the table from Part A. Be sure to label the graph and all data points.
Part C: Create a linear model that represents the Rex’s current weight, in pounds, as a function of his age, in months.
Part D: If Rex continues to grow at the rate of 9 pounds per month beyond the expected six months, how much will Rex weight by the time he is one year old?
Answer:
A.)
In 2 months, Rex is 6 pounds and in 8 months he's 9lbs (from 2 to 8 is 6 months). So I inferred that to get to 9lbs from 6lbs is to go 0.5 pounds more each month.
B.)
2 = 6
3 = 6.5
4 = 7
5 = 7.5
6 = 8
7 = 8.5
8 = 9
C.) I don't think I can create a linear model here. So I don't think its nessesary.
D.)
If Rex were to grow over the expected 6 months, it would be 45.
