HURRY PLEASE!!

Which of these could be the transformation? Choose all that are correct.
A reflection across the line x = 1
A reflection across the line y = 1
A translation 2 units to the left, and then a reflection across the y -axis
A translation 2 units to the right, and then a reflection across the y -axis
A reflection across the y -axis, and then a translation 2 units to the right
A rotation of 180° about the point (1,4)

Answer:

∠ MDF = 39°

Step-by-step explanation:

∠ MDH = 90°, so

∠ MDF + ∠ FDH = 90 , substitute values

2r + 59 + 6r + 111 = 90 , that is

8r + 170 = 90 ( subtract 170 from both sides )

8r = - 80 ( divide both sides by 8 )

r = - 10

Thus

∠ MDF = 2r + 59 = 2(- 10) + 59 = - 20 + 59 = 39°

This is the answer

y = -4x - 2

Work: The line crosses the y-axis at -2 making this the y-intercept. To find the slope, you need to take two points from the graph (you already have (0,-2) from the intercept) and put them in the equation:

y(sub 2) - y(sub 1) all over x (sub 2) over x (sub 1). Sub 1 and two just means the order of the points. so if you took the points (-1,2) and (0,-2), the equation would look like:

(-2-2)/(0-(-1)). This gives you -4/1 which is equal to -4. So now you have your y intercept (-2) and your slope (-4) so you put it into slope - intercept form:

y=mx + b where m is slope and b is y-intercept

Answer:

The answer to your question is -4x -2

Answer:

x should be 11

Step-by-step explanation:

What we know:

The angles shown are 13x + 12, and 2x + 3

The two angles are complementary, which means they equal 180 degrees.

(13x + 12) + (2x + 3) = 180

15x + 15 = 180

15x = 180 - 15

15x = 165

x = 11

Answer:

v=12500-2500h

Step-by-step explanation:

Ok so to create this equation all you need to do is look at what information is given. You start with 12500 gallons of water so we know our equation is going to have 12500 in it.

So far our equation would look like this v=12500

The next information we are given is that it is decreasing by 2500 every hour so we know that we are going to be subtracting 2500 based on how many hours have went by so our equation would then look like this.

v=12500-2500h

we can check this by plugging in some numbers to see if it works. So at Zero hours we should still be at 12500

v=12500-2500(0)

v=12500

Ok so we know that it works for zero, but we should check at least one more number. We know that after 3 hours we would of lost 7500 gallons of water so it should equal 12500-7500=5000 gallons. Lets check this in our equation

v=12500-2500(3)

v=12500-7500

v=5000 Gallons

Answer: 5 inches

Step-by-step explanation:

Perpendicular bisectors must be split directly in half, as they are *bi*sectors, meaning "*two* sections"

Perpendicular means when two angles come together to create a 90° angle

This means that angle BDA is also a 90 degree angle

Since line AC is the line segment split by the perpendicular line segment BD, then you can assume that it is the only 8 inch line, according to multiple laws of geometry. This indicates that segment BC and segment BA must be congruent.

Answer:

x=9

Step-by-step explanation:

600=-200x + 2400

-2400

-200x = -1800

x = 9

Answer:To plot these points on the number line, you should label the long lines on the number line as such starting from the left (-5-already there, -4,-3,-2,-1,0,1,2,3,4,5-already there).

Now take each number and convert the improper fraction into a mixed number. 9/2 = 4 1/2 and -7/2 = -3 1/2.

4 1/2 would plotted on the line exactly in between the 4 and 5.

-3 1/2 would be plotted on the line exactly halfway between -3 and -4.

You will draw a dot to show each of these positions on a number line.

Answer:

–18 feet

Step-by-step explanation:

Given: Garrett begins 18 feet above water level to inspect the lighting, descends 32 feet to inspect the base of the bridge underwater, then descends another 4 feet to check on the concrete anchoring the base.

Step-by-step explanation:

it depends how far you want to take the equation

Step-by-step explanation:

250 - 246 = 4

246 - 242 = 4

Since 250 is 2(mod 4), the negative value term is -2.

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.

If a point  (x, y) is rotated 90° counterclockwise, its new coordinate is (–y, x).

Give point M (3, –6) is rotated 90° counterclockwise:

Step 1: Interchange the x- and y-coordinates to get (-6, 3)

Step 2: Multiply the new x-coordinate by –1 to get (-6(–1), 3)

Step 3: Simplify to get (6, 3)

Therefore she made an error in step 1

Answer: An error in step one

Answer:

x = m - z

Step-by-step explanation:

z = m - x       add x to both sides

z + x = m - x + x

z + x = m            subtract z from both sides

z - z + x = m - z

x = m - z

Answer:

-z + m = x

Step-by-step explanation:

z = m-x

subtract the m from both sides

z-m = -x

you can't have a negative x so multiply everything by -1

-1(z-m = -x)

-z + m = x

Answer:

The equation would be y=7

Step-by-step explanation:

When you multiply a fraction by another fraction or a fraction by a whole number, the rules of fractions dictate the form of the answer. If at least one of the values is negative, you also use the rules for positive and negative signs to determine if the result is positive or negative.
