Answer:
The x would be -2 instead of -0.5.
Step-by-step explanation:
Write the question the symbols represent, then solve it.
f(-2)=-3+2x^2
Answer:
f(-2) = 5
Step-by-step explanation:
Step 1: Define
f(x) = -3 + 2x²
f(-2) is x = -2
Step 2: Substitute and Evaluate
f(-2) = -3 + 2(-2)²
f(-2) = -3 + 2(4)
f(-2) = -3 + 8
f(-2) = 5

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.

What happens when the scale factor is less than 1? What happens when the scale factor is greater than 1?
Answer:
When the absolute value of the scale factor is lower than 1, it decreases the size of the shape.
When the absolute value of the scale factor is greater than 1, the shape will increase in size.
How to Remember it:
Think if the number is a fraction, the shape will be a fraction of the size.
A rectangle has a perimeter of 80. if the length is four more than twice the width, what is the length of the rectangle
Answer:
28
Step-by-step explanation:
l = length
w = width
p = perimeter
w = w
l + l + w + w = p (adding all the rectangle's sides together gets us our perimeter)
l = 2w + 4 (four more than twice the width)
Substitute 2w + 4 for 'l' in the original equation
(2w + 4) + (2w + 4) + w + w = 80
Solve equation normally:
6w + 8 = 80
6w = 72
w = 72/6 = 12
(w = 12)
Length = 2w + 4
Substitute 12 for 'w':
2(12) + 4 = l
24 + 4 = l
28 = l
The length is 28

45 =
Answer: 45 divided by 3 equals 15
he has 15 dollars
Step-by-step explanation: 45= 3 times 15
Answer: 45=3a a=15
Step-by-step explanation:
We know that Molly has $45 or 3 times the amount of money her brother has, and a represents the amount of money her brother has. So we would multiply a by 3. In order to find a we just divide 45 by 3.

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°

. 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.
Solve the following literal equation for y: k = 5y + m

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

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°How many solutions does the following equation have ?
–42 – 7 + 10x = -7 + 62

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
