Answer:
The Answer is 2
EXPLANATION:
y(x)=2x+3
y(x+Δx)=2(x+Δx)+3
=2x+2Δx+3
Δy=y(x+Δx)−y(x)
=(2x+2Δx+3)−(2x+3)
=2Δx
⇒Δy=2Δx, Δy/Δx =2
The rate of change in the equation of a line in slope-intercept form
y = 2x + 3 is 2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An equation of a line y = 2x + 3.
This is in slope-intercept y = mx + b, where 'm' is the slope.
Therefore, The rate of change in y = 2x + 3 is 2.

1. Lisa is saving $50 that she received from her grandmother. She earns $6 each time she walks her neighbor's dog, which she also saves. Which function can be used to find f, the amount of money Lisa will have saved after walking the neighbor's dog d times? A. F = 50d + 6 B. F = −6d + 50 C. F = −6d + 44 D. F = 6d + 50
Answer:
Option D. is the correct answer.
The function that can be used to find f, the amount of money Lisa will have saved is F = 6d + 50
Step-by-step explanation:
From the question,
Lisa is saving $50 that she received from her grandmother,
Also, she earns $6 each time she walks her neighbor's dog, which she also saves.
Now, to determine the function that can be used to find the amount of money Lisa will have saved after walking the neighbor's dog d times, we will determine how much she will earn from walking the dog d times and then add it to the money she received from her grandmother. \
If she earns $6 each time she walks her neighbor's dog, then
she will earn $6×d if she walks the neighbor dog for d times.
$6 × d = $6d
Hence, she will earn $6d from walking the dog d times.
The total amount she will have saved will be $6d + $50.
Hence, the function that can be used to find f, the amount of money Lisa will have saved is F = 6d + 50.
Option D. is the correct answer.

Mohammed built a building that can carry up to 5 tons. If each person weighs about 150 pounds, how many people can fit onto the building that Mohammed built?
Answer:
Step-by-step explanation:
To start solving this problem, you need to figure out how many Pounds( I'll use lbs.) = 5 Tons( I'll use T).
2,000 lbs. = 1 T.
X 5 X 5
10,000 lbs. = 5 T.
Now we divide. That just means that if we know that 1 person( I'll use P) = 150, we just divide 5 T( 10,000 lbs.) by 150 lbs.
10,000/150=66.6666666667

3x-y=5
write each equation in slope-intercept form
Answer:
y = 3x - 5
Step-by-step explanation:
3x-y=5
-3x -3x
-y= -3x + 5
divide each number by -1
-y/-1 = y
-3x/-1 = 3x
5/-1 = -5
The equation 3x - y = 5 can be converted to slope-intercept form as follows: y = 3x - 5
Given is an equation 3x - y = 5, we need to convert it in slope-intercept form.
To convert the equation 3x - y = 5 into slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate the variable "y" on one side of the equation.
Let's rearrange the given equation step by step:
Starting with 3x - y = 5, we can begin by moving the term involving "x" to the other side:
3x - y + y = 5 + y
Simplifying:
3x = y + 5
Now, let's isolate "y" by subtracting "y" from both sides:
3x - y = y + 5 - y
Simplifying:
3x - y = 5
To eliminate the "y" term on the left side, we can add "y" to both sides:
3x - y + y = 5 + y
Simplifying:
3x = 5 + y
Next, let's rearrange the equation to have "y" on the right side:
3x = y + 5
We can write this equation as:
y = 3x - 5
Now the equation is in slope-intercept form (y = mx + b), where the slope "m" is 3, and the y-intercept "b" is -5.

Answer: 3
This is because 15 times 4 equals 60 and that is equal to 1 hour, well when your multiplying fractions what you do to the bottom you have to do to the top so multiply 3 times 4 thats 12 and now you have 12/4 and that is equal to 3.

Step-by-step explanation:
Elon sent a chain letter to his friends, asking them to forward the letter to more friends. The relationship between the elapsed time, t, in days, since Elon sent the email, and the total number of people who receive the email, P(t), is modeled by the following function: P(t)=4×3^t
Answer:
Growing by 3's
Step-by-step explanation:
Every day, the number of people who receive the email increases by a factor of 3.
We have,
In the function, P(t) = [tex]4 \times 3^t,[/tex] the base of the exponent is 3.
This means that for each additional day (t), the exponent increases by 1, and multiplying by 3 represents the growth factor.
For example, if we consider t = 0 (the day Elon sent the email), we substitute t = 0 into the function:
P(0) = 4 * [tex]3^0[/tex] = 4 * 1 = 4
On the first day, 4 people received the email.
If we consider t = 1 (the day after Elon sent the email):
P(1) = 4 * [tex]3^1[/tex] = 4 * 3 = 12
On the second day, the number of people receiving the email increased by a factor of 3 (from 4 to 12).
Similarly, on the third day:
P(2) = 4 * 3² = 4 * 9 = 36
The number of people receiving the email increased by a factor of 3 (from 12 to 36).
This pattern continues, and for each additional day, the number of people who receive the email increases by a factor of 3.
Therefore,
The number of people who receive the email increases by a factor of 3 every day.

Nate has an account that pays 2.76% simple interest per year and wants to accumulate $3,090 in interest from it over the next 15 years. How much money should Nate invest in this account to meet this goal?
a
$4,369.26
b
$4,373.77
c
$1,279.26
d
$7,463.77
Answer:
To achieve this goal, he must invest $7,463.77 ( d)
Step-by-step explanation:
mathematically;
simple interest = PRT/100
I = 3,090
P = ?
R = 2.76%
T = 15 years
3,090 = P * 2.76 * 15/100
100 * 3090 = 41.4 P
P = 309000/41.4
P = 7,463.77

______ hours
PLEASE HELP DUE AT 11:59 PLEASE
Answer:
7 hours
Step-by-step explanation:
This is because 24/3=8
48/4=12
168/12=14
168/8=21
21-14=7
It take him 7 hours to earn the money if he only does yardwork for his grandmother.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Leroy wants to buy a new racing bicycle that costs $168. He earns $24 for 3 hours of yardwork and he earns $48 for 4 hours of babysitting.
We need to find the time take to earn the money if he only does yardwork for his grandmother.
Thus, $24 for 3 hours of yardwork
24/3=8
Again, $48 for 4 hours of babysitting.
48/4=12
Now, 168/12=14
168/8=21

[tex]\frac{6}{6\pi } =\frac{x}{2\pi } \\\frac{1}{\pi } =\frac{x}{2\pi }\\1=\frac{x}{2} \\2=x[/tex]
First, we try to simplify both sides. Next, we multiply both sides by pi. Then, we multiply both sides by 2. Finally, our answer is 2, so 2 radians.

60 percent of a number is 66. Which proportion best represents this relationship.
Answer:
Step-by-step explanation:
If 60% or .60 of a number is 66, then we write and equation to solve for the original number, x.
.6x = 66 Divide each side by .6
.6x/.6 = 66/.6
x = 66/.6
x = 110
as a proportion it would be:
60:100 = 66:110
The proportion that best represents the given relationship is 110 and this can be determined by using the unitary method.
Given :
60 percent of a number is 66.
The following steps can be used in order to determine the proportion that best represents the given relationship:
Step 1 - The unitary method can be used in order to determine the proportion that best represents the given relationship.
Step 2 - Let the unknown number be 'a'.
Step 3 - According to the given data, the value of 'a' can be calculated as:
[tex]a = \dfrac{100}{60}\times 66[/tex]
Step 4 - Simplify the above expression.
[tex]a = 110[/tex]
So, the proportion that best represents the given relationship is 110.
