Answer:
So all the possible solutions are:
[tex]\bold{523,~400,~379~and,~378.6}[/tex]Solution Steps:
First you need to solve the real inequality to understand how to find the rest of the possible equations.
Add 78 to both sides:
[tex]78+78=[/tex] Cancels Out[tex]300+78=378[/tex]So now we know the real answer, but it ask for all possible answers.
(Means anything larger than 300 when you plug it into x - 78 > 300.)
Numbers that are greater than 378:
1.) [tex]377-78=299 > 300[/tex] (False)
2.) [tex]523-78=445>300[/tex] (True)
3.) [tex]0-78=-78>300[/tex] (False)
4.) [tex]-62-78=-140>300[/tex] (False)
5.) [tex]400-78=322>300[/tex] (True)
6.) [tex]379-78=301>300[/tex] (True)
7.) [tex]222-78=144>300[/tex] (False)
8.) [tex]378.6-78=300.6>300[/tex] (True)

Write an equation in point-slope form for the line through the given point with the given slope.(3,-4);m=-1/4
Answers
Answer:
The equation in point-slope form for the line through the given point with the given slope is: [tex]y+3 = -\frac{1}{4}(x-3)[/tex]
Step-by-step explanation:
The point slope form of a line is given by:
[tex]y-y_1 = m(x-x_1)[/tex]
Here m is the slope and (x1,y1) are the coordinates of the point through which the line passes.
Given
m = -1/4 and
(x1,y1) = (3,-4)
Putting the values in the point-slope form of line
[tex]y-(-4) = -\frac{1}{4}(x-3)\\y+4 = -\frac{1}{4}(x-3)[/tex]
Hence,
The equation in point-slope form for the line through the given point with the given slope is: [tex]y+3 = -\frac{1}{4}(x-3)[/tex]

Don't answer if you don't know.
Answers
Answer:
The answer is m=-2 or m=7.
Step-by-step explanation:
The steps to solve this equation are below:
Factor: to get (m+2)(m−7)=0.
m+2=0 or m−7=0
m=−2 or m=7. So, your answer is m=-2 or m=7.
Answer:
m = 7
m = -2
Step-by-step explanation:
ax^2 + bx + c
1m^2 - 5m - 14
a = 1
b = -5
c = -14
-b ± √b^2 - 4ac/2a
-(-5) ± √(-5)^2 - 4(1)(-14)/2(1)
5 ± √25 + 56/2
5 ± √81/2
5 ± 9/2
5 + 9/2
14/2 = 7
5 - 9/2
-4/2 = -2
Find an equation of the line through (3,5) and parallel to y = 3x -7. Write the equation using function notation
f(x)=__
Answers
Given:
Equation of line is [tex]y=3x-7[/tex].
To find:
The equation of line which is parallel line to [tex]y=3x-7[/tex] and passes through (3,5) in function notation.
Solution:
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
On comparing the equation [tex]y=3x-7[/tex] with slope intercept form, we get
[tex]m=3[/tex]
So, slope of given line is 3.
Slope of parallel lines are same. Thus, the slope of parallel line is also 3.
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
The parallel line passes through (3,5) with slope 3. So, the equation of line is
[tex]y-5=3(x-3)[/tex]
[tex]y-5=3x-9[/tex]
Add 5 on both sides.
[tex]y=3x-9+5[/tex]
[tex]y=3x-4[/tex]
Function notation of this equation is
[tex]f(x)=3x-4[/tex]
Therefore, the equation equation in function notation is [tex]f(x)=3x-4[/tex].

P= (x,y) is an arbitrary point on the circle x^2+y^2=36
1. Express the distance d from P to the point A= (8,0) as a function of the x-coordinate of P
2. What are the domain and range of this function d(x)?
Answers
Let (x,y) be an arbitrary point on the circle.
Then d = √[x-3)2 + (y-0)2] = √[x2 - 6x + 9 + y2]
Since x2 + y2 = 1, y2 = 1-x2.
So, d = √[x2 - 6x + 9 + 1 - x2]
d = √(-6x+10)
Domain: x is the x-coordinate of a point on the circle centered at (0,0) with radius 1. So, -1≤x≤1.
But, for d to be defined, we need -6x+10 ≥ 0. So, x ≤ 5/3 (True for all x in [-1,1]).
Domain = [-1,1]
Range: -1 ≤ x ≤ 1 So, 6 ≥ -6x ≥ -6
16 ≥ -6x+10 ≥ 4
4 ≥ √(-6x+10) ≥ 2 That is, 2 ≤ d ≤4
Range: [2,4]

The triangle in each pair are similar. Find the unknown measures.
Answers
Answer:
b=9ft a=32 degrees
Step-by-step explanation:
The triangles in each pair are similar meaning the angles will also be the same.
18ft is 2.25x 8ft so to get b, we multiply the side that is proportionate to it, which is side 4ft
4x2.25=9ft
b=9ft
angle a is directly across from side 4ft which is proportionate to side b.
therefore, angle A is also propertionate to the angle across from side b, 32 degrees.

Which method correctly solves the equation using the distributive property?
-0.2(x-4) = 1.7
Answers
Answer:
[tex] -0.2(x - 4) = - 1.7 [/tex]
[tex] -0.2x + 0.8 = - 1.7 [/tex]
[tex] -0.2x = - 2.5 [/tex]
[tex] x = 12.5 [/tex]
Step-by-step explanation:
Solving [tex] -0.2(x - 4) = - 1.7 [/tex] using the distributive property:
[tex] (-0.2)(x) + (-0.2)(-4) = - 1.7 [/tex]
[tex] -0.2x + 0.8 = - 1.7 [/tex]
Subtract 0.8 from both sides
[tex] -0.2x + 0.8 - 0.8 = - 1.7 - 0.8 [/tex]
[tex] -0.2x = - 2.5 [/tex]
Divide both sides by -0.2
[tex] \frac{-0.2x}{-0.2} = \frac{-2.5}{-0.2} [/tex]
[tex] x = 12.5 [/tex]

Which exponential function is represented by the graph?

O f(x) = 1/2(2)x
O f(x) = 1/2(1/2)x
Of(x) = 2(2)x
PLEASE HELP MEE!
Answers
Answer:
f(x) = [tex]\frac{1}{2}[/tex] [tex](2)^{x}[/tex]
Step-by-step explanation:
Using the standard form of the exponential function
y = a [tex]b^{x}[/tex]
To find a and b , substitute ordered pairs from the graph
Using (0, 0.5 ), then
0.5 = a[tex]b^{0}[/tex] [
a = 0.5 , so
y = [tex]\frac{1}{2}[/tex] [tex]b^{x}[/tex]
Using (1, 1) , then
1 = [tex]\frac{1}{2}[/tex][tex]b^{1}[/tex] , thus
b = 2
f(x) = [tex]\frac{1}{2}[/tex][tex](2)^{x}[/tex] ← exponential function representing graph
