A line has a slope of zero. Which of the following points could this line pass through?
A.(-9, 7) and (9,-7)
B(1, 4) and (3,7)
C. (2,-5) and (6,-5)
D.(1, 2) and (10, 12)
Answer:
C
Step-by-step explanation:
slope 0 means same y
so C (y is -5 for both)
if my answer helps please mark as brainliest.
Answer:
C
Step-by-step explanation:
A line with slope of zero means that the y value doesn't change like the x axis. so we'll need to find points that even though they have different x values, they have the same y value. That. being said C is the answer

Answer:
Answer: Pct women = 56%; pct men = 44%
Step-by-step explanation:
Pct men = total men/total people * 100
men = 750-420 = 330
Pct men = 330/750 *100 = 11/25 *100 = 0.44 * 100 = 44%
.
Pct women = 100% - 44% = 56%
.
Check the answer by checking the percentage of women.
women = 420
Pct women = 420/750 * 100 = 14/25 = 56%
Correct.
.
Answer: Pct women = 56%; pct men = 44%
Describe how to find what value of x must be to minimize the function f(x) = 9x^{2} - 36x + 32 using factoring.
Answer: x=2, f(x)=-4
Step-by-step explanation:
Given
[tex]f(x)=9x^2-36x+32[/tex]
Solving it, add and subtract 4 to it
[tex]\Rightarrow f(x)=9x^2-36x+36-4\\\Rightarrow f(x)=(3x)^2+(6)^2-2\times 3x\times 6-4\\\Rightarrow f(x)=(3x-6)^2-4\\\\\text{here minimum value of }\ (3x-6)^2\ \text{is 0 for x=2}\\\text{so mnimum value of }\ (3x-6)^2-4\ \text{is}\ -4[/tex]
Answer: after you factor use the results (3x-6)^2 - 4 to find the minimum X value but picking a number for the X value to solve to 0.
Step-by-step explanation:
Plug x=2 into the equation and it solves to 0 leave out the -4 because this is the y value

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
here, we have,
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
here, we have,
we know that,
note :
cot a = cosa /sina
here,
so : cot(π/3) = cos(π/3)/sin(π/3)
but : cos(π/3) = 1/2
and sin(π/3) = √3 /2
now, we get,
cot(π/3) = (1/2) / (√3 /2)
= (1/2)×(2/√3 )
= 1/√3
= (1×√3)/( √3 ×√3)
= √3/3
Hence, The solution is, the required value is cot(π/3) = √3/3

7. Angles that are complementary
add up to 90 degrees. If two
complementary angles are in the
ratio of 4:1. how large is the larger
angle?
Answer:
72 degrees is the larger angle
Step-by-step explanation:
SImple ratio problem
So we got a ratio of 4:1 that eqauls to 90 degrees when added up. We can jsut add the 2 numbers 4+1 which will be 5. Now divide 90 by 5 which will equal 18. Now we multiply 18 by each number int he same order of the ratio.
4*18: 1*18
72:18 which equals 90. SInce they ask for the larger angle the answer will be 72.

Answer:
Y = 1
Step-by-step explanation:
Proportional
Answer:
y=1
Step-by-step explanation:
Because they are proportional, the two points have to be equal if they were like a fraction. This means (15,3) would be 15/3 which is equal to 5. The other point is (5,?), so that means that the point will have to be 1. This is because then the point will be equal to 5.
Hope this helps
Natalie is playing the Integer Game and only shows you the four cards shown below. She tells you that the rest of her cards have the same values on them and match one of these four cards.
Missing part of question
(a) If all matching cards will increase her score by 18, what are the matching cards
(b) If all matching cards will decrease her score by 12, what are the matching cards
See attachment for cards
Answer:
(a) 9 card number 2 or 6 card number 3
(b) 6 card number -6
Step-by-step explanation:
Given
The number on the cards are: 2, 3, -6 and 4
Solving (a): An increment of 18
From the card numbers attached, there are 3 positive numbers and 1 negative number
If any of the card numbers is to increase her score, then the card number must be positive. So, we have: card numbers 2, 3 and 4 that fit in this category.
Next, for a card number to give an increment of 18; the card number must be a factor of 18.
So, we have:
[tex]\frac{18}{2} = 9[/tex]
[tex]\frac{18}{3} = 6[/tex]
[tex]\frac{18}{4} = 4.5[/tex]
Only 2 and 3 are factors of 18.
So, Natalie cards are: 9 card number 2 or 6 card number 3
Solving (b): A decrement of 12
If any of the card numbers is to decrease her score, then the card number must be negative. So, we have: card -6 that fit in this category.
Next, is to check if -12 is divisible by -6 (-12 means decrement of 12)
So, we have:
[tex]\frac{-12}{-6} = 2[/tex]
So, Natalie cards are: 6 card number -6
In Las Vegas, a particular sports bet has about a 30% chance of winning. If the bet wins, the bettor will win 15
dollars. If the bet loses, the bettor will lose 10 dollars.
The expected return of placing one of these bets is -2.50 dollars.
Which of the following statements are true?
Choose all answers that apply:
The average return per bet from 2 of these bets must be exactly -2.50 dollars.
It is possible for a bettor to place 2 of these bets and win both of them.
If a bettor places a large number of these bets, they should expect to average a return of about
-2.50 dollars per bet.

In a class there are x amount of students. z amounts of these students are ( y+1 ) years old. The rest of the students are y years old. Write an expression for the sum of all their ages. Simplify.
x = y + z
To simplify,
substitute z = y + 1
x = y + y + 1
x = 2y + 1

!!!Please help will give the brainliest, and please do not put in a silly answer because you want some points or I will report you!!! What are the properties of a kite, trapezoid, square, rectangle, parallelogram, rhombus?
Answer:
In short, they are all quadrilaterals.
Step-by-step explanation:
Rectangle:
- Every angle equals 90 degrees
- Opposite sides are equal and parallel
Square:
- Every angle equals 90 degrees
- Opposite sides are equal and parallel
- Diagonals within the square are perpendicular
Parallelogram:
- Opposite sides are equal and parallel
- Opposite angles are equal
- Any two angles next to each other have to equal 180 degrees, since it would be a line
Rhombus:
- Opposite angles are equal
- All sides are equal
- Opposite sides are parallel
- Diagonals within the square are perpendicular
- Any two angles next to each other have to equal 180 degrees, since it would be a line
Trapedzoid:
- There is only one pair of parallel lines
Kite:
- There are two pairs of equal signs
- There are two equal angles
- You can look at it like two equal triangles glued together

Aiden and Haisem are going to eat the same amount of hamburgers and fries, but from different restaurants. Aiden goes to Burger King and spends $4.75. Each burger costs $1.25 and fries cost $0.50. Haisem spends $6.48 at McDonalods. Each burger costs $1.50 and fries cost $0.99. How many burgers and fries did Aiden and Haisem each buy?
Answer:
the burgers be 3 and fries be 2
Step-by-step explanation:
The computation is shown below:
Let us assume burgers be x
And, the fries be y
Now according to the questiojn
1.25x + 0.50y = $4.75
1.50x + 0.99y = $6.48
Now multiply by 1.2 in the first equation
1.50x + 0.6y = $5.70
1.50x + 0.99y = $6.48
-0.39y = -0.78
y = 2
Now put the value of y in any of the above equation
1.25x + 0.50(2) = $4.75
x = 3
Hence, the burgers be 3 and fries be 2
