The equation of the line which passes through the point (0,-4) and has a gradient of 0. 5 is
The equation of the line which passes through the point (0,-4) and has a gradient of 0. 5 is (x-8)/2.
A straight line can be represented by the "Point-Slope" form of the line.
In point-slope form, we can deduce an equation of any line on the Cartesian coordinate system with the help of its slope/gradient "m" and a point through which it passes (x1,y1).
the equation of Point Slope form is,
(y-y1)=m(x-x1),
where, x and y are any general point on the line.
in the given question the value of the slope/gradient (m) is given as 0.5
and it passes across the point (0,-4)
so according to the equation of the point-slope form,
the equation of line must be,

through a combination of fertility rate and decreased poverty levels, a population’s energy use is growing exponentially 1% per year. how many years until the energy use doubles?
For the energy use to double it will take approximately 69.66 years.
To find out how many years it will take for the energy use to double, we can use the formula for exponential growth:
P = P₀ * (1 + r)^t
where P is the final amount of energy use, P₀ is the initial amount of energy use, r is the growth rate (1% per year in this case), and t is the number of years.
Setting P = 2 * P₀ and solving for t, we get:
2 * P₀ = P₀ * (1 + r)^t
Dividing both sides by P₀:
2 = (1 + r)^t
Taking the natural logarithm of both sides:
ln(2) = t * ln(1 + r)
Dividing both sides by ln(1 + r):
t = ln(2) / ln(1 + r)
Plugging in the values for r = 0.01 and using the natural logarithm function, we get:
t = ln(2) / ln(1 + 0.01) = 69.66 years
So it will take approximately 69.66 years for the energy use to double.

The solution to the inequality:

x ≤ 11 or x ≥ -13
How to solve the absolute value inequality?Here we want to solve the inequality below:

To solve it we need to isolate x, so let's start by multiplying both sides by 2:
2*(1/2)*|x + 1| ≤ 2*6
|x + 1| ≤ 12
Now we can break the absolute value part into two inequalities:
(x + 1) ≤ 12

what is the vertex of this quadratic function?
y=(x+4)^2-9
( , )
Step-by-step explanation:
the vertex form of a quadratic function is
y = (x - h)² + k
with (h, k) being the vertex.
luckily for us the function is already defined in that form.
so, when we compare
y = (x + 4)² - 9
with the general form about (h, k) above we see
h = -4
k = -9
so, the vertex is (-4, -9).
A while back, either James borrowed $12 from his friend Rita or she borrowed $12 from him, but he can’t quite remember which. Either way, he is planning to pay her back or ask that she pay him back this afternoon. If he has $42.80 in his wallet, which equation represents the amount of money he may have after he sees Rita?
|x – 42.80| = 12
|x + 42.80| = 12
|x – 12| = 42.80
|x + 12| = 42.80
The solution is Option A.
The value of the modulus function is | x - 42.80 | = 12
What is Modulus Function?Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the modulus function be represented as A
Now , the equation will be
The amount James borrowed from Rita or Rita borrowed from James = $ 12
And , Let x be the amount of money James will have after he sees Rita
The amount of money with James in his wallet = $ 48
So ,
when James pays Rita , the equation will be
x = 42.80 - 12
On subtracting 42.80 on both sides of the equation , we get
x - 42.80 = -12 be equation (1)
And , when James receives the amount from Rita , the equation is
x = 42.80 + 12
On subtracting 42.80 on both sides of the equation , we get
x - 42.80 = 12 be equation (2)
Now , the modulus function will be
| x - 42.80 | = 12
Hence , the function is | x - 42.80 | = 12

A graph of a quadratic function is a type of parabola, which is a symmetric, U-shaped curve that opens either upward or downward. The equation of a quadratic function is y = ax² + bx + c, where x and y are variables, and a, b, and c are constants.
The graph of a quadratic function is determined by the value of the coefficient a. If a is positive, the parabola opens upward, and if a is negative, the parabola opens downward. The vertex of the parabola is the highest or lowest point on the graph and it is the point of symmetry of the parabola. The x-coordinate of the vertex is given by -b/(2a) and the y-coordinate of the vertex is given by the value of the function at that point.
In the given figure, we can see that it is a parabola, and if we look towards the options, then the third option is a domain of the given function

There are 55 adults and 27 younglings attended the club.
let the number of adults attended the club be x
let the number of younglings attended the club be y
total people attended the club = 82
so,
x + y = 82.....[1]
cost for the adult = $6
cost for the younglings = $4
so total amount collected = $438
so, equation formed is ,
6x + 4y = 438.......[2]
from equation [1]
x + y = 82
x = 82 - y
put this in equation [2]
6(82 - y) + 4y = 438
492 - 6y + 4y = 438
492 - 2y = 438
492 - 438 = 2y
2y = 54
y = 27
put this value in equation [1]
x + y = 82

Answer:
S = 25
Step-by-step explanation:
Since it's stated as a square, that means all sides equal each other
In other words;
s+50 = 3s
To get S alone, we will first subtract 50 on both sides
s = 3s-50
Let's now subtract 3s from both sides
s-3s = -50, aka -2s = -50
Changing those to positive, 2s = 50
Last step is to divide both sides by 2
s = 25

from production for a company where p is the total profit
in dollars and n is the number of hours per day that
the production line operates. Determine the profit when
n = 101/2 hours.
The profit when n = 101/2 hours is $1,842.50.
Determine the profit when n = 101/2 hours.When the production line operates for 101/2 hours, the total profit can be determined using the equation p(n) = 12/5n²-17.When n = 101/2, the equation becomes p(101/2) = 12/5(101/2)²-17.By simplifying this equation, we can find that the total profit for 101/2 hours of production time is p(101/2) = $723.Therefore, when the production line operates for 101/2 hours, the total profit for the company will be $723.The equation p(101/2) = 12/5(101/2)^2 - 17 can be used to determine the total profit when the production line operates for 101/2 hours. To solve this equation, the expression 12/5(101/2)^2 can be simplified to 12(101)^2/25 which evaluates to 12,405. Subtracting 17 from this result yields a total profit of 12,388 dollars when the production line operates for 101/2 hours. The profit when n = 101/2 hours can be calculated by substituting the value of n into the equation p(n) = 12/5n²-17.

What is slope intercept form?
The graph of the equation y = mx + b is a line with slope m and y-intercepts b. The form of the linear equation is called the slope-intercept form, and the values of m and b are real integers.
The slope, m, of a line indicates how steep it is. The gradient of a line is another name for the slope of a line. The y-intercept of a line is the y-coordinate of the location where the line's graph crosses the y-axis.
We are given two points which are (-1,-9) and (1,7).
First, we need to find the slope(m)
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
[tex]m=\frac{7 +9 }{1+1 }[/tex]
m = 16/2
m = 8
We know that b = y₁ - x₁(y₂ - y₁)/(x₂ - x₁)
So,
⇒b = (-9) + 1(7 + 9)/(1+1)
⇒b = -9 + 8
⇒b = -1
The equation comes out to be
⇒y = mx + b
⇒y = 8x -1
