What is the solution to 4|0.5x – 2.5| = 0?
x = 1.25
x = 5
x = –1.25 or x = 1.25
x = –5 or x = 5
Answer:
B. X=5Step-by-step explanation:
To solve this problem, first, you have to isolate the value of x from one side of the equation.
[tex]\sf{4|0.5x-2.5|=0}[/tex]
First, divide by 4 from both sides of an equation.
[tex]\sf{\dfrac{4|0.5x-2.5|}{4}}=\dfrac{0}{4}[/tex]
Solve.
|0.5x-2.5|=0
0.5x-2.5=0
x=5
Therefore the correct answer is x=5.

What is the sum of the polynomials?
(-x2 + 9) + (-3x2 - 11x +4)
Answer:
- 4x² - 11x + 13
Step-by-step explanation:
Given
(- x² + 9) + (- 3x² - 11x + 4) ← remove parenthesis
= - x² + 9 - 3x² - 11x + 4 ← collect like terms
= - 4x² - 11x + 13

Answer:
x=4
Step-by-step explanation:
To find x, start with the equation
(7x-5)=33 because you need the two angles to equal each other
7x=28 next subtract 5 from 33 following the rules of PEMDAS
x=4 now you will end up with x=4, after dividing 28 by 4.

Find the measure of Arc MP
Answer:
Arc MP = 118 degrees
Step-by-step explanation:
From what we have;
Arc MP = PN - MN
for PN, we can see that we have a right triangle; that means the arc measure is 180 degrees
So PN is 180
Now, for MN, we are going to use angle-arc relationship
From what we have;
MN = 2 * 31 = 62 degrees
So we have the measure of MP as;
180 -62 = 118 degrees
Be sure to clearly label each part of your response as Part A, Part B, and Part C.
Part A: If the product of x and 3 is y, write an equation to represent the relationship between the two variables.
Part B: Explain your work in Part A.
Part C: Create a table of values to display five solutions to the equation. Write the solutions as ordered pairs.
Answer:
Part A: y = 3x
Part B: The relationship of y to x is y is 3 times as much as x.
Part C: (0,0), (1,3), (2,6), (3,9), (4,12)
Step-by-step explanation:
Part A: The product of x and 3 (3 times x) is (equals) y. So we can write this linear equation as y = 3x.
Part B: The linear equation is a representation of the relationship between y and x. Y is equivalent to three times x.
Part C: To create solutions to the linear equation, simply plug in a value of x to output a y.
x = 0 -> y = 3(0) = 0; (0,0)
x = 1 -> y = 3(1) = 3; (1,3)
x = 2 -> y = 3(2) = 6; (2,6)
x = 3 -> y = 3(3) = 9; (3,9)
x = 4 -> y = 3(4) = 12; (4, 12)

(3a+1)^{2} -4a^{2} +4a-1
can someone factorize this while explaining how please:)
Answer:
5a(a + 2)
Step-by-step explanation:
Given
(3a + 1)² - 4a² + 4a - 1 ← expand factor using FOIL
= 9a² + 6a + 1 - 4a² + 4a - 1 ← collect like terms
= 5a² + 10a ← factor out 5a from each term
= 5a(a + 2)

slope = change in y over change in x
as y goes up 8, x goes up 1
slope = 8/1 or just 8
Find an equation for the perpendicular bisector of the line segment whose endpoints
are (3, 1) and (-9, -5).
Help plz
Answer:
y= -2x -8
Step-by-step explanation:
I will be writing the equation of the perpendicular bisector in the slope-intercept form which is y=mx +c, where m is the gradient and c is the y-intercept.
A perpendicular bisector is a line that cuts through the other line perpendicularly (at 90°) and into 2 equal parts (and thus passes through the midpoint of the line).
Let's find the gradient of the given line.
[tex]\boxed{gradient = \frac{y1 -y 2}{x1 - x2} }[/tex]
Gradient of given line
[tex] = \frac{1 - ( - 5)}{3 - ( - 9)} [/tex]
[tex] = \frac{1 + 5}{3 + 9} [/tex]
[tex] = \frac{6}{12} [/tex]
[tex] = \frac{1}{2} [/tex]
The product of the gradients of 2 perpendicular lines is -1.
(½)(gradient of perpendicular bisector)= -1
Gradient of perpendicular bisector
= -1 ÷(½)
= -1(2)
= -2
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, we need to substitute a pair of coordinates that the line passes through into the equation. Since the perpendicular bisector passes through the midpoint of the given line, let's find the coordinates of the midpoint.
[tex]\boxed{midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2}) }[/tex]
Midpoint of given line
[tex] = ( \frac{3 - 9}{2} , \frac{1 - 5}{2} )[/tex]
[tex] = ( \frac{ - 6}{2} , \frac{ - 4}{2} )[/tex]
[tex] = ( - 3 , - 2)[/tex]
Substituting (-3, -2) into the equation:
-2= -2(-3) +c
-2= 6 +c
c= -2 -6 (-6 on both sides)
c= -8
Thus, the equation of the perpendicular bisector is y= -2x -8.
Prove: The diagonals of a square are perpendicular.
Answer:
Step-by-step explanation:
Slope of AC= (a-0)/(a-0) = 1
Slope of BD = (0-a)/(a-0) = (-a)/a =-1
Slope of AC x Slope of BD =1 x -1 = -1
Therefore AC perpendicular to BD
Helppp!!!!
Look at this graph what is the equation if the line in slope intercept form
Answer:
y =(2/3)x + 80
Step-by-step explanation:
to get the slope.. change in y/change in x in two points.
so use the points (0,80) and (30,100) and you get 2/3
you know the intercept, where x=0 (0,80) therefore the equation is 2/3x + 80

Answer:
a = 6.7
Step-by-step explanation:
a² + b² = c²

a = 6.7
Circle M has a radius of length 5 inches. A tangent is drawn from exterior point Q to point N on circle M as shown. If QN= 11 inches, determine the measure of
Answer:
look at the box did you see it
Answer:
I hope you are wanting the measure of QM
QM = 12.08 in
Step-by-step explanation:
Because a tangent to a radius forms a 90° angle, use the Pythagorean theorem:
QM² = MN² + QN² = 5² + 11² = 25 + 121 = 146
QM = √146 = 12.08 in
