You are going to rent a car to drive while you are on vacation. There are two car rental packages for you to choose from. The fist package offers a $120 per day flat rate. The second package offers a $100 flat rate plus $0.55 per mile. How many miles would you need to drive while on vacation in order to make the first package the better deal? A.24 miles B. 28 miles C . 32 miles D.37 miles E.45 miles
Answer:
E. 45 miles
Step-by-step explanation:
The difference between the packages is $20. You would need to drive at least 40 miles since 40(0.5) =$20. The best answer is E. 45 miles
You would need to drive 37 miles for the first package ($120 flat rate per day) to be a better deal than the second package ($100 flat rate plus $0.55 per mile).
To determine how many miles you would need to drive for the first package to be a better deal, we need to set up an equation where the cost of both packages is equal. The first package costs a flat rate of $120 per day, while the second package costs a $100 flat rate plus $0.55 per mile. We can write these costs as equations:
First Package: Cost1 = $120Second Package: Cost2 = $100 + $0.55m, where m is the number of miles driven.To find the number of miles required to make the first package cost the same as the second, we set Cost1 equal to Cost2:
$120 = $100 + $0.55m
Solve for m:
$120 - $100 = $0.55m
$20 = $0.55m
m = $20 / $0.55
m = 36.36
Since we need a whole number of miles and it's not an option given in the multiple choices, we can conclude you would need to drive 37 miles for the first package to be the better deal, since after 36 miles, the second package becomes more expensive.

The function g(x) = x2 - 10x + 24 is graphed on a coordinate plane. Where will the function cross the x-axis?
10 (-6, 0) and (4,0)
O (-2, 0) and (-12, 3
O (4,0) and (6,0)
O (12, 0) and (2,0)
Answer:
Option C.
Step-by-step explanation:
The given function is g(x) = x² - 10x + 2x which is graphed on a coordinate plane.
We have to find the coordinates of the points at which function crosses x-axis.
As we know the points at which function crosses x-axis, y-coordinates will be 0/
In other words, g(x) = 0
So x² - 10 + 24 = 0
x - 6x - 4x + 24 = 0
x (x-6) - 4(x - 6) = 0
(x-4) (x-6) = 0
x = 4 and 6
So points at x-axis will be (4, 0 ) and ( 6, 0 )

Answer:
9. A. (3,-2)
10. B. 43°
11. D. 343 cm²
12. A. 15
Step-by-step explanation:
9.Coordinates for summit/vertex U (2,3) after a rotation of 270 degrees.
Rotating a figure by 270 degrees is exactly like rotating it -90 degrees, crossing down over the X-axis (at least for the two summits that are in the first Quadrant).
Doing so, what we do is invert the coordinate numbers (so 2,3 become 3,2) and we change the sign of the Y-value, since we are now in the 4th quadrant, in a negative Y-value domain.
So, vertex U (2,3) becomes (2,-3) after a 270 degrees rotation.
10. Parallelogram JKLM. Determine angle L real value, using the expressions: ∠J =(6x + 7)° , ∠M =(y + 10)° and ∠L =(4x + 19)° ,
Since it's a parallelogram, we know that ∠J = ∠L, so we create an equation and solve it.
6x + 7 = 4x + 19
2x = 12
x = 6
Then we use that value inside the expression given for L:
∠L =(4x + 19)° = (4 (6) + 19)° = (24 + 19)° = 43°
Answer is 43°
11. 2 similar trapezoidal prisms, 5 and 7 of sides respectively. Surface area of the small one is 175 sq cm, what' the surface area of the larger one?
We know that the two prisms are similar.... so all respective sides will be in the same proportion. We know the scale factor is 1.4 (7/5).
So, to calculate the surface area of any side, we'll have something like that:
SA = 1.4x * 1.4y = 1.96xy (x and y representing the dimensions of the small prism)
So, the surface area of the large one is 1.96 times the one of the small one.
SA = 1.96 * 175 = 343

The graph shows two lines, A and B.
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. Another straight line labeled B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.
Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.
Part B: What is the solution to the equations of lines A and B? Explain your answer.
Answer:
Part A:
Since the slopes of the lines are not equal, the pair of equations for lines A and B will have one solution.
Part B:
(3 ,5 ) is the solution to the equations of lines A and B.
Step-by-step explanation:
Part A:
We are required to determine the number of solutions that the pair of equations for lines A and B have. To do this, we shall determine the slope of each line;
A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. The slope is defined as;
(change in y) / (change in x)
The slope of line A is thus;
(2 - 6)/(6 - 2) = -1
A straight line B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.
On the other hand, the slope of line B is;
(6 - 3) / (4.5 - 0) = 2/3
Since the slopes of the lines are not equal, the pair of equations for lines A and B will have one solution.
Part B:
What is the solution to the equations of lines A and B?
We first need to determine the equation of each line;
Line A, the slope was found to be -1 and the line passes through (2,6)
The equation of the line in slope intercept form is;
y = -x + c
6 = -2 + c
c = 8
y = -x + 8
On the other hand, the slope of line B was found to be 2/3 and the line passes through (0,3). Therefore, we have;
y = 2/3x + c
3 = 2/3 (0) + c
c= 3
y = (2/3)x + 3
The graph of these two lines is shown in the attachment below. The lines intersect at (3 ,5 ) which is the solution to the equations of lines A and B.
The graphical solution to a system of linear equations is given by the point of intersection of the two lines representing each equation.

What is a quadratic function (f) whose zeros are 2 and -11
Answer:
f(x) = x² + 9x - 22
Step-by-step explanation:
Given that x = 2 and x = - 11 are zeros, then
(x - 2) and (x + 11) are factors
and f(x) equals the product of the factors
f(x) = (x - 2)(x + 11) ← expand factors
f(x) = x² + 9x - 22 ← is a possible function
The quadratic function [tex]\( f \)[/tex] with zeros at [tex]\( x = 2 \) and \( x = -11 \)[/tex] can be written in factored form as: [tex]\[ f(x) = x^2 + 9x - 22 \][/tex]
The standard form of a quadratic function is:
[tex]\[ f(x) = ax^2 + bx + c \][/tex]
To convert the factored form to standard form, we expand the factors:
[tex]\[ f(x) = a(x^2 + 11x - 2x - 22) \] \[ f(x) = a(x^2 + 9x - 22) \] \[ f(x) = ax^2 + 9ax - 22a \][/tex]
[tex]\[ b = 9a \] \[ c = -22a \][/tex]
So, the quadratic function with zeros at [tex]\( x = 2 \) and \( x = -11 \) is:[/tex]
[tex]\[ f(x) = ax^2 + 9ax - 22a \] \[ f(x) = x^2 + 9x - 22 \][/tex]

Yes, because he could divide by 3.14 to find the diameter and then divide that result by 2 to find the radius. Once he has the radius, he can use the formula.
Yes, because the area will just be twice the circumference so all he has to do is multiply by 2.
No, because the circumference equals c=diameter and there is no pi in 125.6.
No, because the circumference equals c=diameter so he could only find the diameter. He needs the radius for the area formula.

which matrix equation represents the system of equations?
The first answer choice
A system of equations can be represented by a matrix equation. The coefficients of the equations are used to form the matrixes, which can then be solved simultaneously.
Explanation:A system of equations can be represented by a matrix equation using the coefficients of the equations. Let's say you have the following system of equations, where 1. 3x + 2y is equal to 9, and 2. 4x + 5y is equal to 6.
We express this system in the form AX=B, where A is the matrix of coefficients, X is the column matrix of variables, and B is the column matrix of constants. So in this case:
A = [[3, 2], [4, 5]]
X = [x, y]
B = [9, 6].
Adding these together, we can form the matrix equation [[3, 2], [4, 5]] [x, y] = [9, 6]. This represents the given system of equations in matrix form.

Ryan bought 3 books and a magazine . He paid $30 and relieved $5 change if the magazine cost twice as much as each book, find the cost of the magazine.
please explain in algebra only :)
To find the cost of the magazine, represent the cost of each book as 'x'. Use the given information to set up an equation and solve for 'x'.
Explanation:To find the cost of the magazine, let's represent the cost of each book as 'x'. Since the magazine costs twice as much as each book, we can represent the cost of the magazine as '2x'.
According to the problem, Ryan bought 3 books and a magazine and paid $30. We can write this information as an equation:
3x + 2x = 30
Combining like terms, we get:
5x = 30
To isolate the variable 'x', we divide both sides of the equation by 5:
x = 6
Therefore, each book costs $6 and the magazine costs twice as much, which is $12.
The cost of the magazine is $10.
Let's denote the cost of each book as B and the cost of the magazine as M. According to the given information:
Ryan bought 3 books and a magazine, so the total cost is 3B + M.He paid $30 in total, so we have the equation 3B + M = 30.He received $5 in change, which means the total cost minus the payment is equal to the change: 3B + M - 30 = -5.Now, we also know that the magazine costs twice as much as each book, so M = 2B. Substitute M with 2B in the equations:
3B + 2B = 25 (Replace M with 2B in the first equation)5B = 25 (Combine like terms)B = 5 (Divide both sides by 5)Now that we know the cost of each book (B = 6), we can find the cost of the magazine (M) using M = 2B:
M = 2 times 5 = 10
So, the cost of the magazine is $10.

Step-by-step explanation:
Existing walkway
l = 10 ft
w = 4 ft
A₁ = lw = 10 ft × 4 ft = 40 ft²
New walkway
Expanding a measurement by 25 % means that you multiply it by a factor of 1.25.
New length = 10 × 1.25 = 12.5 ft
New width = 4 × 1.25 = 5 ft
A₂ = lw = 12.5 ft × 5 ft = 62.5 ft²
Increase in area
A₂ - A₁ = 62.5 – 40 = 22.5 ft²
