Answer:
You ordered 5 tickets for a show on line...
The cost was $5 a ticket Plus a one time ordering fee of $15.
you total cost was $45 ....
Solving for x will determine the cost of one ticket
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
a taxi charges $5 a mile plus $15 "pull fee" ...
you ride cost a total of $45 ... x is the number of miles that you got driven
Step-by-step explanation:
You rent a car for a down payment of $15 and $5 is charged per mile driven. The total charge is therefore, $45. In essence, x is the no. of miles driven.
According to the question;
We are required to create a real-world problem that could be represented by the equation; 5x + 15 = 45.In essence, x is the no. of miles driven in this scenario.
By solving for x in 5x + 15 = 45, we may determine the no. of miles driven.

HELP PLS HELPIf the length of the minor axis of an ellipse is 6 units and the length of the major axis is 10 units, how far from the center are the foci located?
Answer:
4
Step-by-step explanation:
The distance between the center are the foci located 8 units.
It is required to find the focus is c.
What is ellipse?A closed plane curve generated by a point moving in such a way that the sums of its distances from two fixed points is a constant.
Given that:
The length of the major axis is 2a,
length of the major axis
2a=10
a=5
The length of the minor axis is 2b.
Length of the minor axis
2b=6
b=3
The distance between the center and either focus is c,
c^{2} =a^{2} -b^{2}
c^{2} =5^{2} -3^{2}
c^{2} =25-9
c=8
So, the distance between the center are the foci located 8 units.

Explain the steps necessary to convert a quadratic function in standard form to vertex form.
Answer:
A quadratic function in standard form is converted to vertex form by completing the square. The first two terms are used to create a perfect square trinomial after a zero pair is added. The zero pair is found by taking half of the x-term coefficient and squaring it. The original constant term and the negative value of the zero pair are then combined.

Boat speed: Speed of Current:
Answer: 7 miles/h and 1 miles/h
Step-by-step explanation:
With the speed of current = x + 1
Against the speed of current = x - 1

Step-by-step explanation:
3(4p - 2) +3 = 2p - 5 Remove the brackets on the left
12p - 6 + 3 = 2p - 5 Combine
12p - 3 = 2p -5 Subtract 2p from both sides
12p - 2p - 3 = -5 Combine
10p - 3 = - 5 Add 3 to both sides
10p = -5 + 3
10p = - 2 Divide by 10

The function that represents the inequality of the given graph is;
Option A
Graph Inequalities
From the given graph, the curve with the shaded dot shows less than or equal to because the dot indicates that the maximum input value of x is at that point.
Secondly, the curve without a shaded dot shows that the input function of x is only greater than 3.
Looking at the options, option A is right and we will prove it thus;
for y = x³ - 3
At x = 2, we see that;
y = 2³ - 3
y = 5
This corresponds with the given equation
For the second curve, for y = x² + 6;
At x = 2, we have;
y = 2² + 6
y = 4 + 6
y = 10
This corresponds with what is given and is thus correct.
Thus, option A is the correct answer

Answer:
5
Step-by-step explanation:
This illustrates the Remainder Theorem. If a polynomial f(x) is divided by x−a , the remainder is the constant f(a) , and f(x)=q(x)⋅(x−a)+f(a) , where q(x) is a polynomial with degree one less than the degree of f(x) . Synthetic division is a simpler process for dividing a polynomial by a binomial.

Answer:
BF = |4 – 1| = 3
FC = |4 – 0| = 4
Using the Pythagorean Theorem to find BC:
BC2 = BF2 + FC2
BC2 = 32 + 42
BC2 = 9 + 16
BC = sqaure root 25
BC = 5
Step-by-step explanation:
The length of BC is 5 unit.
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
We need to find the length of BC place point F at (4,4) and draw BF and FC now you have the right ∆BFC with BC as the hypotenuse find BC and FC using the coordinates of B,C, and,F then use the Pythagorean theorem to find BC.
Using the Pythagorean Theorem to find BC:
BC^2 = BF^2 + FC^2
BC^2 = 32 + 42
BC^2 = 9 + 16
BC = √25
BC = 5
So, BF = |4 – 1| = 3
FC = |4 – 0| = 4

Step-by-step explanation:
[tex]\frac{4^8}{(4^2)^-^3}\ / 4^4=4^n[/tex]
Simplify, remember, an exponent raised to the power of another exponent is equal to the product of the two exponents,
[tex]\frac{4^8}{(4^2)^-^3}\ / 4^4=4^n[/tex]
[tex]\frac{4^8}{4^-^6}\ / 4^4=4^n[/tex]
Now bring the term in the denominator (number under the fraction bar) to the numerator (number over the fraction bar). This can be done by multiplying the exponent of the denominator by (-1).
[tex]\frac{4^8}{4^-^6}\ / 4^4=4^n[/tex]
[tex]4^8(4^(^-^1^)^(^-^6^))\ / 4^4=4^n[/tex]
Simplify,
[tex]4^8(4^6)\ / 4^4=4^n[/tex]
Remember, multiplying two numbers of the same base is the same as adding their exponents, apply this property here,
[tex]4^8(4^6)\ / 4^4=4^n[/tex]
[tex]4^1^4\ / 4^4=4^n[/tex]
Dividing two numbers of the same base is the same as subtraction their exponents,
[tex]4^1^4\ / 4^4=4^n[/tex]
[tex]4^1^0=4^n[/tex]
Thus, the following statement can be made,
[tex]4^1^0=4^n[/tex]
[tex]n=10[/tex]
