Answer:
The correct option is D.
Step-by-step explanation:
It is given that the after transformation figure ABCD onto HGFE. It means HGFE is image of ABCD after transformation.
From the figure it is noticed that A(2,-1) and H(-6,1).
Rotation of 90 degree clockwise about the origin followed by the reflection across the x-axis is expressed as
Therefore the image of A(2,-1) is (-1,2), which are not the coordinates of H. Option A is incorrect.
Translation 3 unit up followed by the reflection across the y-axis is expressed as
Therefore the image of A(2,-1) is (-2,2), which are not the coordinates of H. Option B is incorrect.
Reflection across the x-axis followed by rotation of 90 degree counterclockwise about the origin is expressed as
Therefore the image of A(2,-1) is (-1,2), which are not the coordinates of H. Option C is incorrect.
Translation 8 unit left followed by reflection across the x-axis is expressed as
Therefore the image of A(2,-1) is (-6,1), which are the coordinates of H. Option D is correct.
Answer: y = 4x + 5
Step-by-step explanation:
Find the slope of the second line.
4x - y = 12
-y = -4x + 12
y = 4x - 12
slope = 4
Therefore, the slope of the second line must also be 4.
Use point-slope form to write the equation.
y + 3 = 4(x + 2)
y = 4x + 5
Bret paid $12 as sales tax.
A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In a fraction say (x/y), [y] is called denominator.
We have Bret buys a dining table that costs $150 before tax. The sales tax is 8%.
Assume that he paid $[x] as sales tax. Then, we can write -
[x] = 8% of 150
[x] = (8/100) x 150
[x] = 12
Therefore, Bret paid $12 as sales tax.

Answer:
$12
Step-by-step explanation:
to find sales tax you multiply the cost by the percentage
you do 150 * 8%
thats also 150 * 0.08
150 * 0.08 is 12
so you pay $12 in tax
