Waich of the following is a true statement about perpendicular lines?
A. Perpendicular lines intersect to form a 45° angle.
B. Perpendicular lines can also be parallel lines.
C. Perpendicular lines cannot be parallel to each other.
D. Perpendicular lines intersect in at least two points.
Answer:
C
Step-by-step explanation:
perpendicular lines intersect at a 90 degree angle, meaning it is not answer choice A.
B is incorrect because perpendicular lines intersect, so they can not be parallel.
C is correct because parallel lines never intersect, so perpendicular lines can never be parallel to each other.
D is incorrect because perpendicular lines only intersect at one point and create four consistent right angles.

. Three out of four students in school have at least one sibling. If there are 300 students in your school, how many would have at least one sibling?
Answer: 225 students would have at least one sibling.
Step-by-step explanation:
Three out of four is the same as 3/4 meaning that if there are 300 students in your school then 3/4 times 300 will give the number of students with at least one sibling.
3/4 * 300 = 225
This means 225 students would have at least one sibling.
write a linear equation in slope-intercept form with a slope of -5 and passes through the point (-1,8)
Answer:
y=-5x-13
Step-by-step explanation:
use y-y1=m(x-x1)
y+8=-5(x+1)
y+8=-5x-5
subtract 8 from both sides
y=-5x-13
A transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°. What is the value of x?
Answer:
x=116°
Step-by-step explanation:
If a transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°, then the sum of those angles is equal to 180°.
ATQ,
x°+(x-52)°=180°
2x=180°+52
⇒2x=232
⇒x=116°
So, the value of x is 116°
Find x and y. Give reasons to justify your solution.
AB, CD , and EF are straight lines.
Answer:
x = 15.6°, y = 14°Step-by-step explanation:
From the picture we can see that:
∠COE and ∠DOF are vertical angles as formed by intersection of lines CD and EF, so these angles are equalMO⊥AB as ∠MOB = 90°, therefore ∠AOM = 90°Considering the above we get below to find x:
12° + 2x + 3x = 90°5x = 90° - 12°5x = 78°x = 78°/5x = 15.6°And using this to find y:
48° + 3y = 90°3y = 90 - 483y = 42°y = 42°/3y = 14°(PLEASE ANSWER!) Elena went to a store where you can scoop your own popcorn and buy as

1. How much does popcorn cost per ounce?
2. How much popcorn can you buy per dollar?
3. Write two different equations that represent this situation. Use p for
ounces of popcorn and c for cost in dollars.
4. Choose one of your equations, and sketch its graph. Be sure to label
the axes.
Answer:
1. 25 cents per ounce
2. 4 ounces.
3. 10x=$2.50 and $2.50x=10
4. I need picture
Step-by-step explanation:
The cost of popcorn per ounce will be $0.25, the amount of popcorn you can buy per dollar will be 4 ounces per dollar, and the equation that represents the cost will be c = 0.25p.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
Elena went to a store where you can scoop your own popcorn and buy as much as you want. She bought 10 ounces of spicy popcorn for $2.50.
The cost of popcorn per ounce will be
⇒ $2.50 / 10
⇒ $0.25
The amount of popcorn you can buy per dollar will be
⇒ 10 / $2.50
⇒ 4 ounces per dollar
Let p for ounces of popcorn and c for cost in dollars. Then the equation is given as,
c = 0.25p

Let the graph of g be a horizontal shrink by a factor of 1/6 and a reflection in the x-axis, followed by a translation 2 units down of the graph of f(x)=x^2. write a rule for g.
Answer:
Step-by-step explanation:
A function s is the HORIZONTAL SHRINK of a function h by a factor k
if s(x) = h(kx)
It is called a shrink, because for k > 1 that has the effect of compressing
the function h towards the y-axis.
I find the problem statement a little confusing because
using k = 1/6 would result in stretching, not shrinking.
Therefore my guess is that the author means k = 6.
A function r is a REFLECTION of a function h in the x-axis
if r(x) = -h(x).
The reason is that r looks like a mirror image of h,
where the mirror is the x-axis.
A function t is a TRANSLATION 2 units down of a function h
if t(x) = h(x) - 2.
The graph of t looks like h, except shifted down 2 units.
Applying the definitions to your function f:
g(x) = -f(6x) - 2 = -36x^2 - 2
