Sebastian is ordering a taxi from an online taxi service. The taxi charges $3 just for
the pickup and then an additional $0.75 per mile driven. How much would a taxi ride
cost if Sebastian is riding for 10 miles? How much would a taxi ride cost that is m
miles long?
Answer:
10:50
Step-by-step explanation:
Answer:
$10.50 for 10 miles & 0.75m+3 for "m" miles
Step-by-step explanation:
if the taxi charges $3 just for showing up, then in the formula (y=mx+b) 3 would be your "b"
y = mx + 3
if the taxi is charging $0.75 per mile, the mile will be your "x" in the formula, and 0.75 will represent your "m" in the formula
y = 0.75x + 3 - this is your equation for "m" miles
to find how much for 10 miles, substitute 10 for "x" in your formula
y = 0.75 (10) +3
y = 10.50
so it is $10.50 for 10 miles, including the 3 dollar pick up fee.

Written as a simplified polynomial in standard form, what is the result when ( x + 2 ) 2 (x+2) 2 is subtracted from 7 x − 4 7x−4?
Answer:
-x²+3x-8
Step-by-step explanation:
Given polynomials are :
f(x) = (x+2)²
p(x) = 7x−4
We need to find a simplified polynomial when f(x) is subtracted from p(x) i.e.
p(x) - f(x) = 7x−4 - (x+2)²
We know that, (a+b)² = a²+b²+2ab
So,
p(x) - f(x) = 7x−4 -(x²+2²+2(x)(2))
= 7x−4 -(x²+4+4x)
= 7x−4-x²-4-4x
= -x²+3x-8
Hence, the result will be -x²+3x-8.
What is the reference angle for 192°?
A 22°
B. 68°
C. 12°
D. 78°
The required reference angle of angle 192 is 12. OPtion C is correct.
Given that,
An angle of 192°
Reference angle to be determined.
The angle can be defined as the one line inclined over another line.
Angel over angle is of 360° and angle over line is 180°
The function in mathematics to operate and diagnose the function to make the function simple or more coherent is called simplifying and the process is called simplification.
Since in the question, An angle is given of 192° its corresponding and relatable angle is to be determined.
Here, a standard measure of an angle is 180, So let the reference angle b x, for reference angle the angle must be more or less than 180. So,
x = 192 - 180
x = 12
Thus, the required reference angle of angle 192 is 12. Option C is correct.

(2, -4), (x, y) , A , and B all lie on the line. Find an equation relating x and y.
Answer:
An equation relating x and y is:
y = 3/4x - 5.5
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the points
(2, -4), (x, y), A(6, -1), and B(10, 2)
Taking any two points let say A(6, -1), and B(10, 2) to determine the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(6,\:-1\right),\:\left(x_2,\:y_2\right)=\left(10,\:2\right)[/tex]
[tex]m=\frac{2-\left(-1\right)}{10-6}[/tex]
Refine
[tex]m=\frac{3}{4}[/tex]
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = -5.5
Thus, the y-intercept b = -5.5
Thus, substituting b = -5.5 and m = 3/4 in the slope-intercept form of the line equation
y = mx+b
y = 3/4x + (-5.5)
y = 3/4x - 5.5
Therefore, an equation relating x and y is:
y = 3/4x - 5.5

A jug is filled with 1 litre of orange juice. Four 200ml glasses are poured from the jug. How much orange juice is left in the jug?
Answer:
Step-by-step explanation:
As given that
Volume of jug=1 liter=1000ml
also volume of one glass=200ml
and we poured out 4 glasses so total volume of 4 glasses will be,
4 glasses volume = 4*200ml =800ml
Hence the volume of orange left in jug =1000ml-800ml =200mlStep-by-step explanation:
ml to litres = divide by 1000
200/1000 = 0.2×4= 0.8ml

The cost of renting a truck is $40. An additional $0.79 is charged for each mile, m, the truck is driven. Which expression can be used to determine the total cost, in dollars, of renting a truck? (EE.2) *
Answer:
c = 40 + 0.79m
Step-by-step explanation:
The base cost is $40.
So we have:
c = 40
Then, since an additional $0.79 is charged for every mile driven, we add:
+ 0.79m
So then our equation is:
c = 40 + 0.79m
where c = total cost
and m = number of miles driven
If the area of a rectangle with length (4x) is 4x2 + 12x, find the width.
Answer:
The width of a rectangle is: w = x+3
Step-by-step explanation:
Given
The length of rectangle = l = 4x
The area of rectangle = A = 4x² + 12x
To determine
The width of rectangle = w = ?
We know that the formula of the area of the rectangle is
[tex]A = wl[/tex]
substitute A = 4x² + 12x and l = 4x in the equation to determine the width w of the rectangle
4x² + 12x = w×4x
w = [4x² + 12x] / [4x]
Factor 4x² + 12x: 4x(x+3)
w = [ 4x(x+3) ] / [4x]
w = x+3
Therefore, the width of a rectangle is: w = x+3
Find the value of x that makes A || B.

The Science Club wants to print stickers to promote their club and an interest in science. They got a quote to print the stickers from two printers. Pop Art Printing would charge a $25 setup fee and $0.05 per sticker. Sticky Slogans would charge a $12 setup fee and $0.09 per sticker. Write a system of equations that can be used to find the number of stickers for the cost of both printers to be equal.
Answer:
The system of equations =
25 + 0.05x = 12 + 0.09x
The number of stickers where the cost of both printers to be equal is 325 stickers
Step-by-step explanation:
Let the number of stickers = x
Printer 1
Pop Art Printing would charge a $25 setup fee and $0.05 per sticker.
$25 + $0.05× x
25 + 0.05x
Printer 2
Sticky Slogans would charge a $12 setup fee and $0.09 per sticker.
$12 + $0.09 × x
12 + 0.09x
We equate both equations together
The system of equations =
25 + 0.05x = 12 + 0.09x
Collect like terms
25 - 12 = 0.09x - 0.05x
13 = 0.04x
x = 13/0.04
x = 325 stickers
Therefore, the number of stickers where the cost of both printers to be equal is 325 stickers

Which logarithmic equation is equivalent to this exponential equation?
2,400 = 7,500(10) *
A.
B.
I = log
log (3)
I = -log ()
I = -log (*)
I = log (1)
OC.
D.
Answer:
B.
Step-by-step explanation:
2,400 = 7,500[tex](10)^{x}[/tex]
First of all, you want to isolate the [tex](10)^{x}[/tex] by dividing each side by 7,500.
After doing this, you will get
[tex]\frac{2400}{7500}[/tex] = [tex](10)^{-x}[/tex].
Putting this in the logarithmic form, you get [tex]log_{10}[/tex] [tex]\frac{2400}{7500}[/tex] = - x
To get rid of the negative sign, you would simply multiply both dies of the equation by -1. So you would get [tex]-log_{10} \frac{2400}{7500}[/tex] = x.
When you simplify 2400/7500, you get 8/25, so the answer is B.
Hope this helps!

Given logarithmic equation is: [tex]2400 = 7500(10)^{-x}[/tex]To find:The equivalent exponential function to given logarithmic equation.
What is the definition of logarithm?
Logarithm is inverse function to exponentiation.
That means:
[tex]e^a = b \implies a = log_e(b)[/tex]
Transforming given equation to exponential form:[tex]2400 = 7500(10)^{-x}\\\\ \dfrac{2400}{7500} = 10^{-x}\\\\ 10^{-x} = \dfrac{8}{25}\\\\ -x = log_{10}(\dfrac{8}{25})\\\\ x = -log_{10}(\dfrac{8}{25})\\\\[/tex]
Since log with base 10 is simply written log, thus,

if 1 is a root of the equation
[tex]5x^{2} +kx - 3 = 0 [/tex]
find the other root
Step-by-step explanation:
5x² + kx - 3 = 0 has a root x = 1.
=> 5(1)² + (1)k - 3 = 0
=> 5 + k - 3 = 0
=> k = -2.
Therefore we have 5x² - 2x - 3 = 0.
=> (x - 1)(5x + 3) = 0
=> x = 1 or x = -3/5.
Hence the other root is -3/5.

97.94 is 83% of what number?
Answer:
97.94 is 83% of 118
Step-by-step explanation:
Let the missing number be x
97.94=83% of x
I.e, 97.94=83/100 × x
97.94=83x/100
Cross multipy 97.94/1=83x/100
We have, 97.94 × 100 = 83x × 1
9794=83x
Divide both sides by 83 to make x the subject of the formula.
9794/83=83x/83
118=x
