Answer: A. y+8=-2(x-4)
Step-by-step explanation: Point-slope form is y-y₁=m(x-x₁), in which you only substitute three values: the slope, and the x and y coordinate. So, since the slope is -2, you replace it with m. And, if the point is (4, -8), you would substitute the 4 in for x₁, but the -8 is a little more complicated because it is negative. Basically, the negative and the minus sign cancel out and it becomes a plus sign.
Hope this helped! Good luck!
What is the surface area of this triangular prism? 640 square centimeters 672 square centimeters 960 square centimeters 800 square centimeters
Answer:
[tex]672 \:cm^2[/tex]
Step-by-step explanation:
Find the area of the 2 triangle faces and the 3 rectangle faces, then add the areas together to get the total surface area of the triangular prism.
[tex](16 \times 12 \times 1/2) \times 2 + (12 \times 10) + (16 \times 10) + (10 \times 20)[/tex]
[tex]=672[/tex]
Answer: 672 square centimeters
Step-by-step explanation:
20 X 10 = 200
(16 X 12)/2 X 2= 192
10 X 12= 120
16 X 10=160
160 + 120 + 192 + 200 =672

= (4 ; 5)
I do not understand 2 column proof in Geometry. PLEASE HELP
Answer:
A two-column geometric proof consists of a list of statements, and the reasons that we know those statements are true. The statements are listed in a column on the left, and the reasons for which the statements can be made are listed in the right column.
hope this helped :)
Two-column proof:
Two-segment geometric evidence comprises of a rundown of explanations, and the reasons that we realize those announcements are valid. The announcements are recorded in a segment on the left, and the purposes behind which the announcements can be made are recorded in the correct section. A scientific evidence might be composed utilizing a passage, two-sections, or utilizing a stream diagram. The two-section verification is the strategy we use to introduce a sensible contention utilizing a table with two segments. Significant data is generally given to help start a proof and is normally the beginning stage everything being equal.

For which pair of functions is (g circle f) (a) = StartAbsoluteValue a EndAbsoluteValue minus 2? f(a) = a2 – 4 and g (a) = StartRoot a EndRoot f (a) = one-half a minus 1 and g(a) = 2a – 2 f(a) = 5 + a2 and g (a) = StartRoot a minus 5 EndRoot minus 2 f(a) = 3 – 3a and g(a) = 4a – 5
Answer:
f(a) = 5 + a² and g(a) = √(a - 5) - 2
Step-by-step explanation:
(g°f)(a) means that g(a) has to be evaluated at f(a), that is, replace a in g(a) with f(a).
Taking:
f(a) = 5 + a² and g(a) = √(a - 5) - 2
we get:
(g°f)(a) = √(5 + a² - 5) - 2 = √(a²) - 2 = |a| - 2
Where the theorem that states:
for any real number a, √(a²) = |a|was used.

The figure below shows a quadrilateral ABCD. Sides AB and DC are equal and parallel
A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram
Side AB is parallel to side DC, so the alternate interior angles, angle ABD and angle CDB, are congruent Side AB is equal to side DC, and DB is the side common to triangles ABD and CDB. Therefore, the triangles ABD and
CDB are congruent by SAS postulate. By CPCTC, angles DBC and BDA are congruent and sides AD and BC are congruent. Angle DBC and angle BDA form a pair of vertical angles that are congruent. Therefore, AD is
parallel and equal to BC Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel
Which statement best describes a flaw in the students proof?
O Triangles ABD and BCD are congruent by the SSS postulate instead of the SAS postulate.
Triangles ABD and BCD are congruent by the AAS postulate instead of the SAS postulate.
O Angle DBC and angle BDA form a pair of corresponding angles, not a pair of vertical angles
O Angle DBC and angle BDA form a pair of alternate interior angles that are congruent, not a pair of vertical angles
Answer:
Angle DBC and angle BDA form a pair of corresponding angles, not a pair of vertical angles
Step-by-step explanation:
Once it is stated that the triangles ABD and CDB are congruent by SAS postulate, it is concluded that, by CPCTC, angles DBC and BDA are congruent because they are corresponding angles.

Which best describes the range of the function f(x) = { 0)* after it has been reflected over the x-axis?
all real numbers
all real numbers less than 0
all real numbers greater than 0
all real numbers less than or equal to 0
Answer:
all real numbers less than 0
Step-by-step explanation:
In the picture attached, the question is shown.
The function described is an exponential decay with the form:
y = ab^x
where a = 2 and b = 1/4
The range of an exponential decay function is all real numbers greater than 0. This means that after f(x) has been reflected over the x-axis its range is all real numbers less than 0.

a square has a area of 466.56m squared work out the peremiter
Answer:
Perimeter = 86.4 (m)
Step-by-step explanation:
A square (with side x) has an area of 466.56 (m^2)
=> x^2 = 466.56
=> x = sqrt(466.56) = 21.6
=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)

Jeff rear-ended a car on his way to work and damaged his vehicle. He drove his car to the local body shop for an estimate of the cost to repair his car. Jeff has a $500 deductible. The local body shop provided an estimate of $3725. How much will Jeff have to pay? A.) $3225 B.) $3725 C.) $4225 D.) $500
Answer: $500
Step-by-step explanation:
A deductible is the amount that an individual have to pay out of his or her pocket when the person make a claim.
From the question, we are told that Jeff rear-ended a car on his way to work and damaged his vehicle and then drove his car to the local body shop for an estimate of the cost to repair his car. We are told that Jeff has a $500 deductible and the local body shop gives an estimate of $3725.
From this information, Jeff has to pay only $500, and the insurance company will pay the remaining amount which is $3725 - $500 = $3225.
Jeff will pay $500

A Histogram is a graphic representation of data using bars varying in height as per the range of values.
In the given question, the second option correctly represents the data provided in the table using a histogram. It portrays the class ranging from 0.320 - 0.329 with an average of 1 in the first bar, from 0.330 - 0.339 with an average of 14 runs in the second bar, and moves so on till 0.360-0.369 correctly. The other options fail to portray the numerical distribution appropriately and hence, option B is the correct answer.

What is the x-intercept and the y-intercept of the graph of 6x - 3y = 18? Show your work.
Answer:
see below
Step-by-step explanation:
To find the x intercept set y = 0 and solve for x
6x - 3y = 18
6x - 0 = 18
6x = 18
Divide by 6
6x/6 = 18/6
x = 3
(3,0)
To find the y intercept set x = 0 and solve for y
6x - 3y = 18
0 - 3y = 18
-3y = 18
Divide by -3
-3y/-3 = 18/-3
y = -6
(0,-6)
