Step-by-step explanation:
We have that the constructions which would construct a line of reflection that takes point A to point B is Option D
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB
From the Options
We have that
-Construct the perpendicular bisector of segment AB.
A perpendicular bisector will NOT Create a line of reflection that takes point A to point B but rather it will divide the line AB in two equal parts
-Construct a line through B perpendicular to segment AB.
A line through B perpendicular to segment AB will NOT Create a line of reflection that takes point A to point B
-Construct the line passing through A and B.
A line passing through A and B will NOT Create a line of reflection that takes point A to point B but rather will create Line A and B again and not its reflection
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB
In conclusion
The constructions which would construct a line of reflection that takes point A to point B is Option D
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB

PLEASE HELP I WILL GIVE BRIANLIEST 15 POINTS!!! What is the equation in slope-intercept form of the line that crosses the x-axis at 36 and is perpendicular to the line represented by y = -4/9x+5
Answer
A y = 4/9x+16
B y = 4/9x-16
C y= 9/4x+81
D y = 9/4x-81
Answer:
Choice D
Step-by-step explanation:
First we should find the slope of the equation, so since it's perpendicular to the other equation that means it's the opposite and the reciprocal of that slope. So the slope is [tex]\frac{9}{4}[/tex].
Now we have to find the y-intercept. We already know the x-intercept, so we could use that to find the y-intercept. For that we need to know the slope and one ordered pair, which is (36,0). Then we plug into this formula [tex]y=mx+b[/tex].
[tex]y=mx+b\\0=\frac{9}{4}(36)+b\\0=81+b\\b=-81[/tex]
So now that we found the y-intercept we just have to put it all together....
[tex]y=\frac{9}{4}x-81[/tex]

Ruby wrote the standard form of a linear equation as 4x – y =
= 7. Jennifer told her that the equation was not yet in standard form and
gave her the right advice for how to fix it. What advice did Jennifer give to Ruby?
O
Multiply both sides of the equation by 3. The standard form of the equation is 12x - 2y = 21.
Oь
Jennifer told Ruby her equation is already in standard form and there is nothing to correct.
Oc
Multiply both sides of the equation by 3. The standard form of the equation is 12x - 2y = 7
Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x - y = 10.5.

On a coordinate plane, a rectangle and a right triangle are shown. The rectangle has points (0, 4), (4, 10), (7, 8), and (3, 2). The triangle has points (5, 2), (7, 5), and (7, 2). Each unit on the coordinate grid represents 1 yard. The rectangular pool and triangular hot tub shown are both in need of covers. How much total material is needed to cover both?
Answer:
the answer is 29 square yards. took the test got it right
Step-by-step explanation:
The total material needed to cover both is 29 square yards.
What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
Vertices of rectangular pool are (0, 4), (4, 10), (7, 8), and (3, 2).
[tex]AB=\sqrt{(7-3)^{2}+(8-2)^{2}}\\\\= \sqrt{16+36}\\\\=\sqrt{52} =CD[/tex]
[tex]BC=\sqrt{(7-4)^{2}+(8-10)^{2}}\\=\sqrt{9+4}\\\\=\sqrt{13} =DA[/tex]
To find the area of rectangular pool
=Length × Breadth
=√52 ×√13=13×2
=26 sq. yard
Vertices of triangle given are P(5,2),Q(7,2) and R(7,5).
PQ= 2 units, QR= 3 units
Area of right triangle PQR = 1/2 ×PQ×PR
Area =1/2×2×3= 3 sq. yards
To find total material needed to cover( that includes bot rectangular pool and triangular hot tub)

Find the equations of the normals to the curve xy = 3 which are parallel to the
line 3x - y - 2 = 0.
Answer:
y = 3x + 8.
y = 3x - 8
Step-by-step explanation:
The slope of the tangent to the curve at a given point is obtained from the derivative.
xy = 3
y = 3/x
y = 3 x^-1
y' = -3x^-2
The slope of the normal (which is perpendicular to the tangent)
= -1 / -3x^-2 = 1/3 x^2.
Consider the given line:
3x - y - 2 = 0
y = 3x - 2 , so the slope of this line = 3.
Now this line is parallel to the normal so 1/3 x^2 = 3
Therefore x^2 = 9 and x = -3, 3.
Find the equations of the normals:
At x = -3, y = 3/-3 = -1, which gives the equation:
y - (-1) = 3(x - -3)
y = 3x + 8.
At x = 3 , y = 1
y - 1 = 3(x - 3)
y = 3x - 8.

Answer: need the options you choos frome
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
The translation < - 3, - 2 >
Means subtract 3 ( a shift left ) from the x- coordinate and subtract -2 ( a shift down ) from the y- coordinate.
E(3, 6 ) → E'(3 - 3, 6 - 2 ) → E'(0, 4 )
F(1, 0 ) → F'(1 - 3, 0 - 2 ) → F'(- 2, - 2 )
G(- 1, 3 ) → G'(- 1 - 3, 3 - 2 ) → G'(- 4, 1 )

Edward deposited $9,000 into a savings account 2 years ago. The simple interest rate is 4% How
much money did Edward earn in interest?
Substitute the values into the equation.
Interest=$ 3.0. years
Please help
Answer:
$734.40
Step-by-step explanation:
y=9,000(1.04)^t is our equation for this.
The 9,000 is the starting amount.
1.04 is the 4% since 4% is 4/100 which equals 0.04, then we add 1 to that since it's increasing in value.
y represents our output.
t represents time (in years for this equation)
Since they give us the amount of years since he deposited the $9,000, we put the number they gave us (2 years) into the equation, replacing t.
y=9,000(1.04)^2
Put the right side into a calculator and it gives you 9734.4.
That's the total amount he has now, so to find how much he earned we subtract the starting amount (9000).
734.4.
Edward earned $734.40.

2 Name a point that is in the solution set of the quadratic inequality shown
below.
Answer:
Point (3, 2) is in the solution set of the quadratic inequality
Step-by-step explanation:
If the sign of the inequality is > OR <, then the line represents the inequality is a dashed line and all the points on the line do not belong to the solution set of the inequality If the sign of the inequality is ≥ OR ≤, then the line represents the inequality is a solid line and all the points on the line belong to the solution set of the inequalityFrom the given figure
∵ The line the inequality is a solid line
∴ The solution set of inequality have all the points on the line and
the points on the shaded area
→ We can choose any point on the line or on the red area
∵ Point (3, 2) is the vertex of the parabola
∴ Point (3, 2) is in the solution set of the quadratic inequality
