Based on theword problem, the inequality of the word problem is 7/2 + 4h >= 1
What are inequalities?Inequalities are used to represent expressions that do not have equal values i.e. unequal expression
How to translate the word problem to an inequality?The word problem is given as
Half of 7 added to product of h and 4 is at least 1
At least 1 means greater than or equal to 1
So, the word problem becomes
Half of 7 added to product of h and 4 is at least 1 ⇒ Half of 7 added to product of h and 4 >= 1
The product of h and 4 means 4h

Linear Regression
The table below shows the average price of a movie ticket during certain years.
PLS HELP
Answer:
a) y = -441.105 + 0.2232x
b) 2043
Step-by-step explanation:
Correlation measures how closely two variables are linked.
If two variables are correlated, you can draw a line of best fit on the scatter plot.
Explanatory (independent) variable is drawn on the x-axis.Response (dependent) variable is drawn on the y-axis.Plot the points from the table where:
x = yeary = average price (in dollars)(See attached graph).
We can see that the points lie close to a straight line. Therefore, a line of best fit with a positive slope can be drawn, since the two variables are positively correlated.
Linear regression is a method for finding the equation of a line of best fit on a scatter plot.
The regression line of y on x:
[tex]y = a + bx[/tex]
where a = y-intercept and b = slope
If b is positive, the variables are positively correlated.If b is negative, the variables are negatively correlated.We cannot find the y-intercept from inspection of the scatter plot (attached) since we would need to extend the x-axis to thousands of years.
Therefore, to find the regression equation, use a graphing calculator:
[tex]y=-441.105+0.2232x[/tex]
To find the approximate year the movie ticket price will reach $15, substitute y = 15 into the equation and solve for x:
[tex]\implies -441.105+0.2232x=15[/tex]
[tex]\implies 0.2232x=456.105[/tex]
[tex]\implies x=2043.481...[/tex]
Therefore, the approximate year the movie ticket price will reach $15 is during 2043.
Note:
For this problem, we have used the line of best fit (regression line) to predict a value of that is outside the range of the original data. When using values outside the range to predict corresponding values, this is called extrapolation. These predictions can be unreliable because there is no evidence that the relationship described by the regression line is true for all values of x. Therefore, caution should be applied in these cases.
Find the real and imaginary solutions of each equation.

A solution that is real in its nature is called the real solution of that equation.
X + 5 = 0
We can solve the above equation as,
X + 5 = 0
X = -5
Now, if we plug the value of X into the equation,
X + 5 = 0
-5 + 5 = 0
0 = 0
The solution is real and is true for this equation.
While the solution of an algebraic expression solution is imaginary if it is the square root of a negative number. It involves the imaginary unit iota.

f = 7x + 4y
5x + y ≥
60
x+6y ≥ 60
4x+6y ≥ 204
x ≥ 0, y ≥0
Minimum =[?]
The minimum of the objective function, f, subject to the constraints is (10.3, 8.3)
Plugging in 5 points, the intersections of the bounds of the 5 constraints, yields the least solution, f = 7x + 4y.
(0,60) provides 240
(6,30) f= 42+120 = 162
(10.3,8.3) = 72.1+ 33.2 = 105.3
(48,2) = 336+ 8 = 344
(60,0) = 420
At the moment when the minimum f is approximately (10.3,8,3)
5x+y = 60 and x+6y = 60 intersect at that point. Multiply the first equation by 6 and take the second equation out to get 30x + 6y = 360.
x + 6y = 60
29x = 300
Rounding to 10.3, x = 300/29 = about 10.345
adjusted to 8.3, y = 60-5x = 60 - 5(10.345) = 60-51.724
10.3, 8.3 reduces the value of the function f = 7x+4y.

Solve the mass energy equivalence formula e=m c² for c .

(I) c=√(e-m)
The correct option is (H) c=√e/m.
The solution for mass energy equivalence formula e=m c² for the value of c is c = √e/m.
What is termed as the mass energy equivalence?An equation deduced from Einstein's Special Theory of Relativity that expresses the correlation between the mass & energy of mass objects.
Some key features related to the mass energy equivalence are-
E = mc², where E is the object's energy in joules, m is its relativistic mass in kilograms, & c is the speed of light (approximately 3 X 10⁸ meters per second). The concept of mass-energy equivalence states that the total mass of a system can change while the total & total momentum stay unchanged; for instance, the collision of an electron & a proton shatters the mass of both particles while producing energy in the form of photons. The discovery of mass-energy equivalence was critical in developing a theory of atomic fission and fusion reactions.As per the given question, the expression is;
=> e = m c²
=> c² = e/m
Now, taking square root of both sides.
=> c=√e/m
Therefore, the value of the c derived from the mass energy equivalence formula e=m c² is c=√e/m.

From the question, we are to determine how long it would take Amal to run 1 mile
From the given information,
Amal can run 1\8 mile in 1 1\2 minutes.
First, we will calculate Amal's speed
Using the formula,
Speed = Distance/ Time
Then,
Amal's speed = 1/8 ÷ 1 1/2
Amal's speed = 1/8 ÷ 3/2
Amal's speed = 1/8 × 2/3
Amal's speed =1/12 miles/minute
Now, we will determine how long it would take him to run 1 mile
Time = Distance/ Speed
Time = 1 ÷ 1/12
Time = 1 × 12/1
Time = 12 minutes

The equation in slope intercept form of the line that passes through the points (-4, 2) and (12, 6) is y = 0.25x + 3
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the equation of the line?The points are given as
(-4, 2) and (12, 6)
Calculate the slope of the points using
m = (y2 - y1)/(x2 - x1)
So, we have
m = (6 - 2)/(12 + 4)
Evaluate
m = 0.25
The equation is then calculated as
y = m(x - x1) + y1
Where
(x1, y1) = (-4, 2)
So, we have
y = 0.25(x + 4) + 2
Expand
y = 0.25x + 1 + 2
Evaluate
y = 0.25x + 3

If a polynomial f(x) has a remainder of -4 when divided by x-8, what is f(8)?
The value of f(8) is -4.
What is a polynomial?Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer.
For example, 4x + 5x - 1 is a polynomial.
We can consider the polynomial to be:
f(x) = x - 12 so that when we divided by x - 8 we get a remainder of -4.
i.e
(x - 12) / (x-8)
x - 8 ) x - 12 ( 1
x - 8 [ (x - 8) x 1 = x - 8 ]
-4 [ we change the sign of the coefficient ]
[ x - 8 becomes (-x + 8) ]
[ x gets canceled and -12 + 8 = -4 ]
We see that the quotient is 1 and the remainder is -4.
Now,
We can use this polynomial f(x) = x - 12.
f(8) = 8 - 12 = -4
We can also directly say that the value of f(8) is -4 because the remainder is given as -4.
Thus,
The value of f(8) is -4.
