Cydney is proving that perpendicular lines have slopes that are opposite reciprocals. She draws line p and labels two points on the line as (0, a) and (b, 0). Enter the answers, in simplest form, in the boxes to complete the proof. The slope of line p is . Rotate line p 90° counterclockwise about the origin to get line q. The labeled points on line p map to (−a, 0) and ( , ) on line q. The slope of line q is . The slopes of the lines are opposite reciprocals because the product of the slopes is .
Answer:
Slope of p = -a/b
(0, b) is on line q
Slope of q = ( b - 0) / (0 - -a) = b/a
Product of the slopes = (-a/b) (b/a) = (-ab) /(ab) = -1

Carlos is packing bags for treats at a party. Every bag has exactly the same amount of treats in it. Carlos has 25 granola bars and 35 small popcorn balls. What is the greatest number of treat bags Carlos can make?
Answer:
5 bags
Step-by-step explanation:
Given
[tex]Granola\ Bars = 25[/tex]
[tex]Popcorn\ Balls = 35[/tex]
Required
Determine the greatest number of bags
This question illustrates greatest common factor (GCF).
The number of bags will be solved by getting the GCF of 25 and 35.
This is shown below:
[tex]25 = 1 * 5 * 5[/tex]
[tex]35 = 1 * 5 * 7[/tex]
[tex]GCF = 1 * 5[/tex]
[tex]GCF = 5[/tex]
Hence, Carlos will need 5 bags

Is the domain of the function represented by the data shown in the graph discrete or continuous?
9514 1404 393
Answer:
continuousdistance traveled by walkingStep-by-step explanation:
You can draw the graph without lifting your pencil, so it is "continuous."
Rows, drinks, and books are all things that are counted. That is, their number takes on discrete values.
Time, on the other hand, is continuous--able to take on any value.
The graph best models distance as a function of time.

What is the answer to: three times a number K is more than 14
Answer:
k > 14/3
General Formulas and Concepts:
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Translate
"Three" = 3
"times" = multiplication
"a number k" = k
"is more than" = >
"14" = 14
Step 2: Set up inequality
3k > 14
Step 3: Solve for k
Divide both sides by 3: k > 14/3Here we see that any number k greater than 14/3, or 4.666..., will work as a solution.

will name the brainliest!!
Answer:
x/3 + 34
Step-by-step explanation:
The quotient of x and 3 would be written as x/3.

BD bisects m m Find m
The text of the question is not visible in the answering window. I'll reproduce it here:
BD bisects <ABC.
m <ABD= 2.5x + 8.6
m<CBD = 3.5x - 3.4
Find m<ABC
Answer:
[tex]m\angle ABC = 77.2^\circ[/tex]
Step-by-step explanation:
We have an angle ABC and a line BD bisecting it.
If an angle is bisected, then the two formed angles are congruent, that is
[tex]m\angle ABD=m\angle CBD[/tex]
Substituting the algebraic expressions for both angles:
[tex]2.5x + 8.6=3.5x - 3.4[/tex]
Subtracting 8.6 and 3.5x:
[tex]2.5x - 3.5x = -8.6 - 3.4[/tex]
Operating:
[tex]-x = -12[/tex]
[tex]x = 12[/tex]
The two angles are:
[tex]m\angle ABD=2.5x + 8.6=2.5(12) + 8.6=38.6^\circ[/tex]
[tex]m\angle CBD=3.5x - 3.4 = 38.6^\circ[/tex]
As expected, both angles have the same measure.
The measure of the total angle ABC is twice any of those:
[tex]m\angle ABC = 2*38.6^\circ=77.2^\circ[/tex]
[tex]\mathbf{m\angle ABC = 77.2^\circ}[/tex]
solve for z: -4 - (z - 6) = 12
Answer:
z = -10
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-4 - (z - 6) = 12
Step 2: Solve for z
Distribute negative: -4 - z + 6 = 12Combine like terms: -z + 2 = 12Subtract 2 on both sides: -z = 10Divide -1 on both sides: z = -10Step 3: Check
Plug in z to verify it's a solution.
Substitute: -4 - (-10 - 6) = 12Subtract: -4 - (-16) = 12Simplify: -4 + 16 = 12Add: 12 = 12Here we see that 12 does indeed equal 12.
∴ z = -10 is a solution of the equation.
Answer:
z = -10
Step-by-step explanation:
-4 -(z+6)=12
2-z=12
-z =12-2
ans= z = -10
What is the solution set for 9x^2-25=0?
Answer:
A
Step-by-step explanation:
9x^2-25=0
x= 5/3 and -5/3
By solving quadratic equation [tex]9x^2-25=0[/tex] we got solution set as [tex]\{\frac{-5}{4}, \frac{5}{4} \}[/tex]
What is quadratic equation ?Any equation that can be written in form as [tex]ax^{2}+bx+c=0[/tex] , where x is variable and a, b and c are any real numbers and a ≠ 0 is called quadratic equation .
given quadratic equation :
[tex]9x^2-25=0\\\\[/tex]
Adding 25 both sides
[tex]9x^2-25+25=0+25\\\\\Rightarrow 9x^2=25[/tex]
Dividing by 9 on both sides
[tex]\frac{9x^2}{9}=\frac{25}{9}\\\\x^2= \frac{25}{9}[/tex]
Taking square root both sides
[tex]x= \pm \sqrt(\frac{25}{9})[/tex]
[tex]x= \pm \frac{5}{4}[/tex]
[tex]x= \{\frac{-5}{4}, \frac{5}{4} \}[/tex]
By solving quadratic equation [tex]9x^2-25=0[/tex] we got solution set as [tex]\{\frac{-5}{4}, \frac{5}{4} \}[/tex]

Which of these is the value of y in terms of a?
Option 1 : y = 3a – 35
Option 2 : y = 2ab – 3b
Option 3 : y = 9a – 35
Option 4: y = 3 – 2a
Answer: [tex]y=3-2a[/tex], Option 4
Step-by-step explanation:

Step-by-step explanation:
83x - 6) = 6(4x + 8)
Answer:
[tex]x = \frac{54}{59}[/tex]
Step-by-step explanation:
I'm assuming you meant (83x - 6). Either way, the parentheses aren't needed there as there aren't any numbers outside of the parentheses on that side of the equation.
So:
Remember PEMDAS
P – Parentheses
E – Exponents
M – Multiplication /D – Division (whichever comes first from left to right)
A – Addition /S – Subtraction (whichever comes first from left to right)
Nothing needs to be distributed on the left side, so let's distribute the right side.
6(4x + 8)
6 * 4x = 24x
6 * 8 = 48
Now we have 24x + 48
83x - 6 = 24x + 48
Now, we must isolate the x so that in the end, we can get x =
83x - 6 = 24x + 48
+ 6 +6
83x = 24x + 54
-24x -24x
59x = 54
Now, we have isolated the x! Finally, we want x to = 1 so that it will be x = instead of 59x =.
[tex]\frac{59x}{59} = \frac{54}{59}[/tex]
Because 54/59 does not divide into a rational number or simplify any further, we can keep it as a fraction.
[tex]x = \frac{54}{59}[/tex]

What is the slope of the line graphed
Explain answer
GIVING BRAINIEST
Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (0, 6) ← 2 points on the line
m = [tex]\frac{6-0}{0+3}[/tex] = [tex]\frac{6}{3}[/tex] = 2
Answer:
The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the [tex]\frac{Rise}{Run}[/tex] technique. Moving up 2 units and to the right 1 unit, which would be represented by [tex]\frac{2}{1}[/tex].
