Company B has an initial fee of $75 and charges an additional $0.70 for every mile driven. For what mileage will Company A charge less than Company B? Use m for the number of miles driven, and solve your inequality for m.
For the mileage of 80 miles company A will charge less than company B.
So, the inequality is m≤80.
What is meant by inequality?A variety of notations are available to denote different kinds of inequalities. An inequality in mathematics is a relationship between two expressions or values that is not equal. To resolve an inequality, follow these steps: First, multiply each term by the total of the least common denominators of all the fractions to be subtracted.

The height of an object that is dropped from the top of a tower is given by the expression −16t2 + 441, where t is the time in seconds.
(a) Factor this expression.
(b) Use a spreadsheet to determine how many seconds it takes the object to fall to a height of 377 feet. (Use 0.5-second intervals for t.)
t = BLANK sec
i need this fast
Hello,
I hope you and your family are doing well!
Part A)
The given expression is in the form y = -16t^2 + 441, which is a quadratic equation. A quadratic equation can be factored into the form (ax + b)(cx + d) = 0, where a, b, c, and d are constants.
To factor in the given expression, we can start by completing the square. To complete the square, we need to add and subtract the square of half of the coefficient of the x^2 term, which is (1/2)(-16) = -8. This gives us:
y = -16t^2 + 441 = (-16t^2 - 8t^2) + 441 = -24t^2 + 441
Now, we can rewrite the expression as follows:
y = -24t^2 + 441 = (-8t^2) + 441
To complete the square, we need to add and subtract (1/2)^2(-8)^2 = 16:
y = (-8t^2 + 16) + 425
This expression can be rewritten as:
y = (-8t^2 + 16) + (20t)^2
So the expression can be factored as:
y = (-8t + 4)(2t - 5) (this is the answer)
Part B)
To find the time it takes the object to fall to a height of 377 feet, we can set y equal to 377 and solve for t. Substituting the factored form of the expression into the equation and solving for t gives us:
377 = (-8t + 4)(2t - 5)
We can then solve this equation by setting each factor equal to 0 and solving for t. This gives us:
-8t + 4 = 0
2t - 5 = 0
Solving these equations separately gives us:
t = 1/2
t = 5/2
The time it takes the object to fall to a height of 377 feet is t = 1/2 seconds. (or 0.5 in decimal form)

Select the correct answer. Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(-13) = 20 B. g(-4) = -11 C. g(7) = -1 D. g(0) = 2
The correct answer is option B: "g(-4) = -11". This statement is consistent with the given information about the domain, range, and specific values of the function g. Since the domain of g is -20 ≤ x ≤ 5, the value x = -4 is within the domain of the function, and therefore we can evaluate g at this value. Similarly, since the range of g is -5 ≤ g(x) ≤ 45, the value g(-4) = -11 is within the range of the function. Furthermore, since g(0) = -2 and g(-9) = 6, we know that g takes on negative values, which is consistent with the fact that g(-4) = -11.
Option A, C, and D are all incorrect because they do not satisfy the conditions of the domain and range of the function g. For example, option A states that g(-13) = 20, but since the domain of g is -20 ≤ x ≤ 5, the value x = -13 is not within the domain of the function, and therefore it is not possible to evaluate g at this value. Similarly, option C states that g(7) = -1, but since the range of g is -5 ≤ g(x) ≤ 45, the value g(7) = -1 is not within the range of the function, and therefore this statement cannot be true for g. Option D states that g(0) = 2, but since we are given that g(0) = -2, this statement is not consistent with the given information about the function g.

The monomial that we need to add to have a square of a difference is:
-2bc
Which binomial should we introduce?
Remember that the square of a difference is written as:
(a - b)^2 = a^2 - 2ab + b^2
Here we have the two terms:
0.01*b^2 + ... + 100c^2
We can rewrite the known terms as:
0.01*b^2 = (0.1*b)^2
100*c^2 = (10c)^2
Then our expression becomes:
(0.1*b)^2 + ... + (10c)^2
And the missing term must be:
-2*(0.1b)*(10c) = -2bc

(a)Reflection: in the x-axis
(b) Rotation: 180°
The vertices after reflection will be (-6, 1), (-3, 2), (-5, 7) and the vertices after rotation of 180° will be (6, 1), (3, 2), (5, 7).
What is the reflection of points?A form of Euclidean space isometry in geometry is called a point reflection, also known as a point inversion, center inversion, or asymmetry through a point.
An object is said to have point symmetry if it is unchanged under a point reflection, and central symmetry or being centrally symmetric if it is invariant below a point reflective thinking through its center.
As per the given information in the question,
The given vertices of the triangle are:
D(-6, -1), E(-3, -2), F(-5, -7).
a.
The equation towards reflection in the x-axis: (x, -y)
D = (-6, -1)
Reflected vertex = (-6, 1)
E = (-3, -2)
Reflected vertex = (-3, 2)
F = (-5, -7)
Reflected vertex = (-5, 7)
b.
Now let's find out the rotation of 180° of the given points,
As we can see that the vertices are in the third quadrant because both the points of each vertex are negative, so after rotation of 180° it will move to the 1st quadrant where all the points are positive.
So,
D = (-6, -1)
After rotation, D = (6, 1)
E = (-3, -2)
After rotation, E = (3, 2)
F = (-5, -7)
After rotation, F= (5, 7)

The equation of line s is y=–4x–5/3
Line t includes the point (–3,3) and is parallel to line s. What is the equation of line t
Answer:
y = -4x-9
Step-by-step explanation:
The slope must stay the same for parallel lines, which is -4. Now we will plug the point into slope-intercept form(y=mx+b) where m is the slope and b is the y-intercept. Plugging in -4 for the slope and (-3, 3) for x and y, we get [tex]3=-4*13 + b[/tex], or [tex]3 = 12 + b[/tex]. Subtracting 12 from sides gives us that b = -9, which is the y-intercept! We know have both the slope and y-intercept, so we get that the equation is y = -4x - 9.
Hope this helps!
