The equation of the graph that is obtained by translating the parent function is as follows:
g(x) = |x + 2| + 1
How to write the equation of the translated graph?The parent function is given as
f(x)= |x|
The following is a translation of the parent function f(x), which may be derived from the graph as follows:
2 units left translation
1 unit up translation
The translation of the sequence mentioned above is expressed as
(x, y) = (x + 2, y + 1)
So, we have
g(x) = |x + 2| + 1
Therefore, the equation of the graph that has been translated is g(x) = |x + 2| + 1

25 students submitted the HW this week, which was 77% of the class. How many students are in the class?
Answer:
Step-by-step explanation:
25 divide 77 = 0.32467532 x 100 = 32 (Leave off the rest, there is no such thing as a fraction of a person in this)
Simplified: (25/77)*100 = 32
To check our answer we would do 32 x 77%(.77) = 24.64 round-up and you get 25!

what is the slope of the line that passes through the points (6,-8) and (6,-3)
We have a vertical line, so we have an undefined slope.
How to get the slope of the line?The general linear equation in the slope-intercept form is given by:
y = m*x + k
Where we define k as the y-intercept and m as the slope.
If we know that the line passes through two points (a, b) and (c, d), then the slope is given by the formula:
m = (d - b)/(c - a)
In this case we have the points (6,-8) and (6,-3), then the slope will give:
m = (-3 + 8)/(6 - 6)
Notice that the denominator becomes zero, so we have a "slope of infinity", thing that happens for vertical lines
Basically, these lines have undefined slopes, so that is the correct answer.

Solve. Check for extraneous solutions. (x+3)¹/₂-1=x
-2 is the extraneous solution of the equation.
The equation is:
[tex](x + 3)^{1/2}[/tex] - 1 = x
To find the extraneous solution of the expression first we need to find the value of x.
[tex](x + 3)^{1/2}[/tex] = x + 1
Squaring both sides we have,
[tex](x+ 3)^{}[/tex] = [tex](x + 1)^{2}[/tex]
x + 3 = [tex]x^{2}[/tex] + 2x + 1
[tex]x^{2}[/tex] + x - 2 = 0
[tex]x^{2}[/tex] + 2x - x - 2 = 0
x ( x + 2 ) - 1 (x + 2) = 0
(x+2) (x-1)=0
x = -2, 1
Now we have to put the value of x in the equation:
x = -2
[tex](-2 +3)^{1/2}[/tex] - 1 = -2
1-1 =-2
0≠ -2
x = 1
[tex](1 + 3)^{1/2}[/tex] - 1= 1

The answer to this question is (gof)(x)=2x+7
According to question:
Given: f(x)=4 x, g(x)=1/2 x+7,h(x)=-2 x+4
(gof)(x)=g(f(x))=g(4x)=1/2×4x+7=2x+7(fog)(x)=f(g(x))=f(x/2+7)=4×(x/2+7)=2x+28We always simplify everything in brackets first using BODMAS. Therefore, in order to compute f(g(x)), g(x) must first be calculated and then substituted within f(x). Similar to this, in order to determine g(f(x)), f(x) must first be computed and then substituted in g(x). In other words, the sequence is important when locating the composite functions. It implies that g(f(x)) and f(g(x)) may not be equal. The following procedures are used to obtain the composite function f(g(a)) for any two functions f(x) and g(x).
By changing x = a in g, find g(a) (x).

The sum of numbers from 1 to 100 is 50 × 101.
Carl Friedrich Gauss is a renowned mathematician. He has contributed many theories to the fields of mathematics and physics.
The sum of the first hundred numbers is calculated by making pairs of two numbers. The sum of these pairs is 101.
And there is a total of 50 pairs.
So, the sum of all these numbers is,

Answer:
x=m/2+k , k≠-2
Step-by-step explanation:
2x+kx=m
Factor out x from the expression:
(2+k)x=m
Assume 2+k≠0 and divide both sides of the equation by 2+k:
x=m/2k , 2+k≠0
Rewrite the restriction:
x=m/2+k≠-2
Solution:
x=m/2+k , k≠-2
The value of x in the given expression is x = m / (k+2)
What is an expression?An expression is a mathematical statement containing variables, numerical, and they are related by at least one mathematical operation.
Given an expression, 2x + kx = m
We are asked to rearrange the values and find the value of x.
Therefore,
2x + kx = m
Since, two terms have same variable, therefore, taking x common from both,
x(2+k) = m
x(k+2) = m
Now, transpose (k+2) to right side, we get,
x = m / (k+2)
Hence, we get the value of x as, x = m / (k+2)

2. x = 8; m<GDH = 126°; m<FDH = 200°; m<FDE = 137°
How to Find the Measures of Angles?1. Since QS bisects angle PQT, therefore:
measure of angle PQS = measure of angle SQT
Given:
m<SQT = 8x - 25
m<PQT = 9x + 34
m<SQR = 112°
Thus:
m<PQT = 2(m<SQT)
Substitute
9x + 34 = 2(8x - 25)
9x + 34 = 16x - 50
9x - 16x = -34 - 50
-7x = -84
x = 12
m<PQS = m<SQT = 8x - 25
Plug in the value of x
m<PQS = 8x - 25 = 8(12) - 25
m<PQS = 71°
m<PQT = 9x + 34 = 9(12) + 34
m<PQT = 142°
m<TQR = m<SQR - m<SQT [angle addition theorem]
m<TQR = 112 - 71
m<TQR = 41°
2. Given:
m<GDE = 8x - 1
m<EDH = 6x + 15
m<CDF = 43
m<GDE = m<EDH [reason: DE bisects GDH]
Substitute
8x - 1 = 6x + 15
8x - 6x = 1 + 15
2x = 16
2x/2 = 16/2
x = 8
m<GDH = 2(m<GDE)
m<GDH = 2(8x - 1)
m<GDH = 16x - 2 = 16(8) - 2
m<GDH = 126°
m<FDG = 180 - m<CDF - m<GDE
m<FDG = 180 - 43 - (8x - 1)
m<FDG = 180 - 43 - (8(8) - 1)
m<FDG = 180 - 43 - 63
m<FDG = 74°
m<FDH = m<FDG + m<GDH
m<FDH = 74 + 126
m<FDH = 200°
m<FDE = m<FDG + m<GDE
