Answer:If (x + 1) is a factor of the polynomial p(x), then p(x) can be written as:
p(x) = (x + 1) q(x)
for some polynomial q(x). By substituting x = -1 into this expression, we can find the value of c:
p(-1) = (-1 + 1) q(-1) = 0 q(-1) = 0
So,
0 = 5(-1)^4 + 7(-1)^3 - 2(-1)^2 - 3(-1) + c
= -5 + 7 - 2 + 3 + c
= c = 3
So, the value of c that makes (x + 1) a factor of the polynomial p(x) = 5x^4 + 7x^3 - 2x^2 - 3x + c is c = 3.
F(x)=|x| is transformed to g(x)=|x|+4 what transformation happens from f(x) to g(x)
Step-by-step explanation:
The transformation from the function f(x) = |x| to the function g(x) = |x| + 4 can be thought of as a vertical shift upward by 4 units. The shape of the absolute value function remains unchanged, but the entire graph is shifted upward along the y-axis by 4 units. This can be visualized by observing that for any value of x, g(x) = f(x) + 4.
So, the transformation of f(x) to g(x) is a vertical shift upward by 4 units
3. Mrs. Doyle asks Lowell to create a verbal

Lowell complete the task correctly? Justify
your answer.
A $25 charge is added for
rush delivery
Lowell's verbal representation of the equation y = x - 25 is "y is equal to x minus 25".
This verbal representation accurately describes the equation. In the equation, y is the dependent variable and x is the independent variable. The equation says that y is equal to x minus 25, which means that for every value of x, there is a corresponding value of y that is x minus 25.
So, Lowell has completed the task correctly.

The sum of their ages is 30. Find their ages.
Their ages are _____
(Use a comma to separate answers as needed.)
Their ages are 5 years, 25 years
How to find their ages?Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.
Let L and Y represent the age of the older person and younger person respectively.
Using the given information, we can write:
L = 4Y + 5 --- (1)
L + Y = 30 --- (2)
From (2):
L = 30 - Y --- (3)
Put (3) in (1):
L = 4Y + 5
30 - Y = 4Y + 5
4Y + Y = 30 - 5
5Y = 25
Y = 25/5
Y = 5 years
Put Y = 5 into (3):
L = 30 - Y
L = 30 - 5
L = 25 years
Their ages are 5 years, 25 years

Grayson is going to invest in an account paying an interest rate of 4% compounded
continuously. How much would Grayson need to invest, to the nearest dollar, for the
value of the account to reach $15,000 in 5 years?
Grayson would need to invest approximately $10,994 to the nearest dollar for the value of the account to reach $15,000 in 5 years.
What is continuously compounded interest?
Continuous compounded interest indicates that an account balance is constantly earning interest and reinvesting that money so that it, too, earns interest.
The formula for continuous compounding is given by:
[tex]A = Pe^{rt}[/tex]
where A is the amount in the account after t years, P is the principal amount (the amount invested), r is the annual interest rate, and e is the base of the natural logarithm.
We want to find P when A = $15,000, r = 0.04, and t = 5 years.
Substituting these values into the formula, we get:
[tex]15000 =Pe^{0.04*5}[/tex]
Simplifying the right-hand side, we get:
[tex]15000 =Pe^{0.2}[/tex]
Dividing both sides by e^(0.2), we get:
[tex]P= \frac{15000}{e^{0.2}}[/tex]
Using a calculator, we get:
P ≈ $10,994
Therefore, Grayson would need to invest approximately $10,994 to the nearest dollar for the value of the account to reach $15,000 in 5 years.

If the x-values are equal for two points, then the two points are on a ____ line
If the x-values are equal for two points, then the two points are on a vertical line.
When will x - values for two points be equal ?When there is a vertical line, then it will cross the x - axis at only a single point. This point will be such that all the x - values on the line would be - values because the line stands on only one point on the x - axis.
The same applies to the y - axis for horizontal lines. This is because the horizontal line would cross the y - axis at a single point. For instance, all the points on y = 2, would have a y - value of 2.

A right rectangular prism has a square base with sides 1/2 in. Long. The volume of the prism is 3/8 in to the third power. What is the prism?
Answer:
If the base of the right rectangular prism is a square with sides that are 1/2 inch long, then the area of the base is (1/2)^2 = 1/4 square inches.
Since the volume of the prism is given as 3/8 cubic inches, we can use the formula for volume of a right rectangular prism (V = Bh) to solve for the height of the prism:
V = Bh
3/8 = (1/4)h
Multiplying both sides by 4, we get:
3 = h
So the height of the prism is 3 inches.
Therefore, the right rectangular prism has a square base with sides 1/2 inch long and a height of 3 inches, making it a 1/2 x 1/2 x 3 inch rectangular prism.
A 10-ft board is cut into 2 pieces so that one piece of 6 feet longer than 3 times the shorter piece. If the shorter piece is x feet long find the lengths of both pieces

From the information given, we have that;
The shorter side = x
The longer side of the board = 6 +3x
The total length = 10
Substitute the values, we have;
x + 6 + 3x = 10
collect the like terms
x + 3x = 10 -6
Add or substract the like terms, we have;
4x = 4
Now, make 'x' the subject of formula by dividing by 4, we get;

10. Last night, 4 friends went out to dinner at a restaurant. They split the bill evenly. Each friend paid $12.75 for his or her meal and each left the same amount for a tip, t. The total dinner bill including the tip was $61. What equation could you use to describe the situation?
Answer:
Step-by-step explanation:
Let's call the number of friends "f". Since each friend paid $12.75 for their meal, the cost of the meals can be represented as f * 12.75. And since each friend left the same amount for a tip, the cost of the tips can be represented as t * f.
The total cost of the dinner including the tip was $61, so we can write the following equation:
f * 12.75 + t * f = 61
Expanding the left side of the equation:
12.75f + t * f = 61
Combining like terms:
13.75f + t = 61
Solving for t:
t = 61 - 13.75f
So, the equation that describes the situation is t = 61 - 13.75f.
A certain antihistamine is often prescribed for allergies. A typical dose for a 100-pound person is 19 mg every six hours. Complete parts (a) and (b) below. a. Following this dosage, how many 13.2 mg chewable tablets would be taken in a week? b. This antihistamine also comes in a liquid form with a concentration of 13.2 mg/ 10mL. Following the prescribed dosage, how much liquid antihistamine should a 100-pound person take in a week?
A 100-pound person could take mL in a week? this is the question i need answered the most...thank you
Answer: First, let's find out how many times a 100-pound person would take the antihistamine in a week:
Every 6 hours * 24 hours/day = 4 times a day
4 times a day * 7 days/week = 28 times a week
Next, let's find the number of 13.2 mg chewable tablets taken in a week:
A typical dose of 19 mg * 28 doses/week = 532 mg
532 mg / 13.2 mg/tablet = 40 tablets
So, a 100-pound person would take 40 chewable tablets in a week following the prescribed dosage.
Now, let's find the amount of liquid antihistamine to be taken in a week:
A typical dose of 19 mg * 28 doses/week = 532 mg
532 mg / 13.2 mg/10 mL = 40.15 mL
So, a 100-pound person would take 40.15 mL of liquid antihistamine in a week following the prescribed dosage.

Points A, B, and C are colinear in that order. Find xusing the segment addtion postulate method
AC = 3X +3
AB = -1 + 2X
BC=11
Using the segment addition postulate approach, the valve of x is 7.
What purposes do postulates serve?A postulate is a claim that is accepted as true in the lack of supporting data. Postulates serve as a basis for the verification of succeeding propositions and serve the dual purpose of defining concepts that are not yet specified. Two points determine a line segment. A line segment can go on for ever along a line.
The segment addition postulate states that if three points A, B, and C are parallel to one another in that sequence, then the lengths of AB and BC added together equal the length of AC.
AC = AB + BC
Substituting the given values, we get:
3x+3 = (-1 + 2x)+11
When the right side of the equation is simplified, we obtain:
3x + 3 = 2x + 10
Subtracting 2x from both sides, we get:
x + 3 = 10
Subtracting 3 from both sides, we get:
x = 7
Therefore, x = 7.

Algebra: let f(x)= 3x+7 f^-1 (x)=
Answer:
Step-by-step explanation:
To find the inverse of a function, we need to switch the x and y values and solve for y (or x, depending on how the original function is written). The inverse of the function f(x) = 3x + 7 is written as f^-1(x). To find f^-1(x), we can follow these steps:
Replace the function f(x) with y to make it easier to manipulate: y = 3x + 7.
Swap the x and y variables: x = 3y + 7.
Solve for y:
Subtract 7 from both sides to get x - 7 = 3y.
Divide both sides by 3 to get (x - 7) / 3 = y.
Write the inverse function using f^-1(x) instead of y:
f^-1(x) = (x - 7) / 3
So, the inverse of the function f(x) = 3x + 7 is f^-1(x) = (x - 7) / 3.
