18x+3y=-21
slope -intercept form: y=mx+b
move 18x to the other side
sign changes from +18x to -18x
18x-18x+3y=-18x-21
3y=-18x-21
divide both sides by 3 to find slope-intercept form
3y/3=-18x/3-21/3
y=-6x-7
answer: y=-6x-7

Consider quadrilateral EFGH.
The slope of EF is .
Which statements are true? Check all that apply.
EH is parallel to FG.
EF is perpendicular to EH.
HG is neither parallel nor perpendicular to FG.
Quadrilateral EFGH is a rectangle because it is a parallelogram with four right angles.
Quadrilateral EFGH is a trapezoid because it has exactly one pair of parallel opposite sides.
Answers
(B) EF is perpendicular to EH.
Quadrilateral:A quadrilateral in geometry is a four-sided polygon with four sides and four corners (vertices). The Latin words Quadri, a variation of four, and latus, meaning "side," are the source of the name. In reference to other polygons, it is also known as a tetragon, from the Greek "tetra" for "four" and "gon" for "corner" or "angle" (e.g. pentagon). Since "gon" is an anagram for "angle," it is also known as a quadrangle or 4-angle. Display style "square ABCD" is sometimes used to indicate a quadrilateral with the vertices A, B, C, and D.Therefore, the correct option is (B) EF is perpendicular to EH.

The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V. Write the direct variation equation for the scenario above.
Answers
Answer:
[tex]D=kV^2[/tex]
Step-by-step explanation:
In this problem, it is given that,
The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V.
We need to write the direct variation equation for the scenario above. It can be given by :
[tex]D\propto V^2[/tex]
To remove the constant of proportionality, we put k.
[tex]D=kV^2[/tex]
k is any constant
Hence, this is the required solution.
Segment A'B' is parallel to segment AB. What is the length of segment AB? What is the length of segment B'B? Your answer should be in decimal form with only one decimal place.
Answers
B’B is 3.5
Step-by-step explanation:
Segment A'B' is parallel to segment AB.
So, The length of segment AB is 7.5 units
The length of segment B'B is 3.5 units
Given :
Segment A'B' is parallel to segment AB. Few sides of the triangle is given.
Apply basic proportionality theorem
When A'B' is parallel to segment AB then sides are proportional
[tex]\frac{CB'}{B'B} =\frac{CA'}{A'A}[/tex]
Substitute the values
[tex]\frac{7}{B'B} =\frac{6}{3} \\cross \; multiply\\7(3)=B'B(6)\\21=B'B(6)\\Divide \; by \; 6\\B'B= \frac{21}{6} \\B'B=3.5[/tex]
Now we find AB by making a proportion
[tex]\frac{CA'}{CA} =\frac{BA'}{BA} \\\frac{6}{9} =\frac{5}{AB} \\Cross \; multiply\\6(AB)=5 \cdot 9\\6AB=45\\Divide \; by \; 6\\AB=7.5[/tex]
The length of segment AB is 7.5 units
The length of segment B'B is 3.5 units

The main idea is using the Pythagorean formula to find the length of line segment [tex]DB[/tex].
Alr so you use the formula [tex]A^2 + B^2 = C^2[/tex]
[tex]C^2[/tex] is already given and is [tex]2\sqrt{5}[/tex]
and [tex]A^2[/tex] is [tex]3\sqrt{2}[/tex]
So using algebraic rules you'll get [tex]B[/tex] as:

Now using the formula: [tex]\frac{1}{2} b * h[/tex], you can find the area of tri ABD and CBD which would be [tex]3[/tex] and [tex]1[/tex] so add them up and you get [tex]4[/tex]!

What is the image point of (0,9) after a translation left 1 unit and down 2 units?
Answers
Answer:-1,7
Step-by-step explanation:
The point after translation left 1 unit and down 2 units will be (-1, 7)
What is translation?A translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system.
Given that, a point (0,9) is being translated left 1 unit and down 2 units
We know that, translation rule for, left and down is,
(x, y) = (x-a), (y-b) where a and b are units by which points are being translated.
Therefore,
(0, 9) = (0-1, 9-2)
= (-1, 7)
Hence, the point after translation left 1 unit and down 2 units will be (-1, 7)
