Which is the graph of f(x) = x2 – 2x + 3? Help its timed, also don't want an verified answers
Answers
to resolve this type of exercise you must in first place to verify The determinant of the function to know if it cuts to the x axis, with the following formula b^2-4ac, if this value is less than zero then the function , do not cut the x axis, now -(2)^2-4(1)(3) = -8, as this value is negative, it means that is less than zero nd the function do not cut the x axis
2) the graph cut the y axis eN Y = 3 for x= o, F(0) = 0+2*0+3 = 3
3) This is the graph

20 POINTS!!!
a point is translated 2 units to the right and five units down on the coordinate plane, how will this affect the x- and y- coordinates of the point?
Answers
Let y start out as y
The original point is (x , y)
Start with moving the x 2 units to the right.
To the right means going more positive.
x would become x + 2
down means the value is going in the minus y direction you are subtracting 5 from the original y
y - 5 is what you get.

Which graph represents the function f(x)=1/x+3-2
Answers
files are attached below
Answer:
The graph as shown below.
Step-by-step explanation:
Given : The function [tex]f(x)=\frac{1}{x-3}-2[/tex]
We have to plot the graph for the given function [tex]f(x)=\frac{1}{x-3}-2[/tex]
Consider the given function [tex]f(x)=\frac{1}{x-3}-2[/tex]
Domain of function [tex]f(x)=\frac{1}{x-3}-2[/tex]
DOMAIN is set of input values for which the function is real and has defined values.
So, The given function is undefined at x = 3
So, Domain is [tex]x<3\quad \mathrm{or}\quad \:x>3[/tex]
RANGE is the set of values of dependent variable for which the function is defined.
Inverse of given function is [tex]y=\frac{3x+7}{x+2}[/tex]
Now, domain of inverse function is [tex]f\left(x\right)<-2\quad \mathrm{or}\quad \:f\left(x\right)>-2[/tex]
Now, x intercept and y- intercepts
x intercept where y = 0 and y- intercept where x= 0
Let f(x) = y
Then [tex]y=\frac{1}{x-3}-2[/tex]
Put x = 0
thus y- intercept is [tex]\left(0,\:-\frac{7}{3}\right)[/tex]
Now put y = 0
Then x- intercept is [tex]\left(\frac{7}{2},\:0\right)[/tex]
Now, Calculate the vertical and horizontal asymptotes,
Vertical asymptotes,
Go over every undefined point and check if at least one of the following statements is satisfied.
[tex]\lim _{x\to a^-}f\left(x\right)=\pm \infty[/tex]
[tex]\lim _{x\to a^+}f\left(x\right)=\pm \infty[/tex]
Thus, The vertical asymptotes is x = 3
And For horizontal asymptotes,
[tex]\mathrm{Check\:if\:at\:}x\to \pm \infty \mathrm{\:the\:function\:}y=\frac{1}{x-3}-2\mathrm{\:behaves\:as\:a\:line,\:}y=mx+b[/tex]
We have y = -2 as horizontal asymptotes.
Plot we get the graph as shown below.

A survey questioned 1,000 high school students. the survey revealed that 48% are honor roll students. of those who are honor roll students, 45% play sports in school and 22% of those that are not honor roll students, don't play sports. what is the probability that a high school student selected at random plays sports in school?
Answers
Of the remaining 520 non-honor-roll students, 22%, or 114.4 don't play sports. That leaves 405.6 that do.
Thus, of the 1000 students surveyed, 216 +405.6 = 621.6 play sports, for a ratio of 621.6/1000 = 0.6126.
The probability that a randomly chosen student plays sports in school is about 0.6216.

m∠1=32°
Find: m∠S, m∠T, m∠Q
Answers
__________________________________________________________
Explanation:
__________________________________________________________
To find "m∠Q" :
Consider the triangle formed by ∠D , ∠1, and ∠Q ;
Given m∠1 = 32° ;
and m∠D = 90° (a "right triangle" ; as shown in "image attached" ;
and by definition, all triangles have 3 angles and 3 sides; and all 3 angles of a triangle add up to 180° ;
→ m∠Q = 180 − (90 + 32) = 180 − 122 = 58 ;
_______________________________________________________
Since this is an "isosceles triangle" ;
→ m∠S = m∠Q = 58° .
Since all angles of any triangle add up to " 180° " ;
→ m∠T = 180 − (58 + 58) = 180 − 116 = 64 ;
____________________________________________
Answer: m∠S = 58 ° ; m∠T = 64 ° ; m∠Q = 58 ° .
____________________________________________
Answer:
s=58 degrees, Q=58 degrees, T=64 degrees
Step-by-step explanation:

Solve the system of equations. -6y+11x = -36
-4y+7x=-24 −6y+11x=−36 −4y+7x=−24 x= y=
Answers
y -(11/6)x = 6
y -(7/4)x = 6
Subtracting one of these from the other tells you x=0, so you know immediately that y=6.
The solution is ...
x = 0
y = 6
The solution to the system of equations is:
x = 0
y = 6
To solve the system of equations:
-6y + 11x = -36
-4y + 7x = -24
You can use the method of substitution or elimination. I'll use the elimination method here.
First, multiply the second equation by 3 to make the coefficients of y in both equations equal:
-6y + 11x = -36
-12y + 21x = -72
Now, you can subtract the first equation from the second equation to eliminate x:
(-12y + 21x) - (-6y + 11x) = (-72) - (-36)
Simplify:
-12y + 21x + 6y - 11x = -72 + 36
Combine like terms:
-6y + 10x = -36
Now, divide both sides by 2 to simplify:
(-6y + 10x) / 2 = (-36) / 2
-3y + 5x = -18
Now you have a simplified system of equations:
-6y + 11x = -36
-3y + 5x = -18
You can solve this system using either the substitution or elimination method. Let's use the elimination method again. Multiply the second equation by 2 to make the coefficients of x equal:
-6y + 11x = -36
-6y + 10x = -36
Now, subtract the first equation from the second equation:
(-6y + 10x) - (-6y + 11x) = (-36) - (-36)
Simplify:
-6y + 10x + 6y - 11x = -36 + 36
Combine like terms:
-1x = 0
Now, solve for x:
x = 0
Now that you know the value of x, you can substitute it into one of the original equations to find the value of y. Let's use the first equation:
-6y + 11x = -36
-6y + 11(0) = -36
Simplify:
-6y = -36
Now, solve for y:
y = (-36) / (-6)
y = 6

Mason earns $70,000 per year and puts 7% of his earnings into a savings account. What is the total amount in Mason's account after 1 year if the interest rate is 3%?
A. $147
B. $72,100
C. $5,047
D. $2,100
Answers
Annual income of Mason is 70,000 dollars.
He saves 7% of his annual earnings into a saving account.
So, his savings would be 7% of 70,000 = 0.07 x 70,000 = 4,900 dollars.
The saving account gives an interest rate of 3% per annum.
So the interest accrued on 4900 dollars over the year would be 3% of 4,900 = 0.03 x 4,900 = 147 dollars.
Total amount in the saving account would be sum of principal amount and interest accrued.
Total balance = principal amount + interest accrued.
Total balance = 4900 + 147 = 5,047 dollars.
Hence, option C is correct i.e. 5,047 dollars.
