12x-18=90 whats the answer ?

Answer:

no a parallelogram doesn't have all equal sides but a square does

Step-by-step explanation:

E is the midpoint of DA, and F is the midpoint of DB. This means EF is a midsegment of the triangle. It is half as long as AB, and EF is also parallel to AB.

When we extend EF to form segment EC, it is now twice as long compared to EF. So that shows EC is the same length as AB, in other words, EC = AB. Also, EC is parallel to AB. This works due to points E, F, and C being on the same line.

Since EC || AB, we know that angle EBA = angle BEC. These are alternate interior angles.

From the reflective property, we can say EB = EB

---------------

Using these three facts

to prove that triangle EBA is congruent to triangle BEC. The next step is to use CPCTC (corresponding parts of congruent triangles are congruent) to lead to

angle BEA = angle EBC

we can use the alternate interior angle theorem converse to conclude that EA is parallel to BC.

-----------------

In summary, we have proven:

By the definition of what it means to be a parallelogram, we have proven quadrilateral EABC is a parallelogram. In short, we've shown that the opposite sides are parallel.

The equation expressing the number y of shopping centers in terms of the number x of years after 1992 will be LINEAR in nature

The standard equation is expressed as;

y = mx+c

m is the slope

c is the intercept

If in 1992​, there were 41,984 shopping centers in a certain country and in 2002​, there were 48,225 we can express this as coordinate points

(0, 41984) and (10, 48,225)

Get the slope

m = 48,225-41,984/10-0

m = 6241/10

m = 624.1

Get the intercept, substitute m = 624.1 and the point (0,48225) into the formula y = mx+c

48225 = 624.1(0)+c

48225 = 0+c

c = 48225

Get the required equation

y = 624.1x+48225

Answer:

C (Kinda blurry)

Step-by-step explanation:

By looking at the two points you can tell the slope is 1, because it moves 2 over it moves 2 up.

If you back track to find the y value when x=0, then you have the x intercept.

So the equation is y=x+2. In this equation the values are jumbled so you just do a few transformations to make the equation look like the correct one.

subtract y on each side to get 0=x-y+2

subtract 2 from each side to get -2=x-y

now you have x-y=-2

Answer: 9/14 of a pound each day.

Step-by-step explanation:

We can convert the mixed fraction into an improper fraction:

4 1/2 → 9/2

Now we divide by 7, since there are 7 days in a week:

9/2 ÷ 7

When we divide, by a number, it can be placed in the denominator:

9/2*7 = 9/14

There's no other way to simplify it, so that's our final answer.

Answer:

C. 92 degrees

Step-by-step explanation:

Given that the [tex]\angle{wxy}=[/tex]92° which is one of the angles of the quadrilateral WXYZ

The quadrilateral is first rotated by 270° about the origin and then translated 2 units up, the new position of the quadrilateral is W'X'Y'Z'.

The shape of the quadrilateral is remained unchanged due to rotation and translation, so all the angles of the final quadrilateral W'X'Y'Z' is the same as the angles of the given quadrilateral WXYZ.

So,[tex]\angle{w'x'y'}= \angle{wxy}[/tex]

By using the given value,

[tex]\angle{w'x'y'}=[/tex] 92°

Hence, option (C) is correct.

Rotating and translating quadrilateral WXYZ would not change its angle measure.

The measure of W'X'Y is (c) 92 degrees

The given parameters are:

[tex]\mathbf{WXY = 92^o}[/tex]

Translation and rotation are rigid transformations, and they do not alter the angle measure of the shape being transformed.

This means that: angles WXY and W'X'Y are congruent

i.e.

[tex]\mathbf{WXY = W'X'Y}[/tex]

So, we have:

[tex]\mathbf{W'X'Y = 92}[/tex]

Hence, the true option is (c) 92 degrees

Answer:

y = 8x - 55

Step-by-step explanation:

Given

Point (x1,y1) = (7,1)

Slope, m = 8

Required

Determine the equation of the line

The question asks that the equation to be in form: y = mx + b

This above form is a representation of point-slope and is calculated using the following formula:

y - y1 = m(x - x1)

Substitute values for y1, x1 and m

y - 1 = 8(x - 7)

Open bracket

y - 1 = 8x - 56

Collect Like Terms

y = 8x - 56 + 1

y = 8x - 55

Hence, the calculated line equation in form of y = mx + b is y = 8x - 55

Answer:

x=3.75

Step-by-step explanation:

15x - 45= 3x

Subtract 15x from both sides:

-45 = -12x

Divide both sides by -12, the -12's cancel and you get:

-45/-12 = 3.75

x= 3.75

I hope this helps!! blessings, xx,nm! :)

Answer:

y = -3/4*x + 1

Step-by-step explanation:

y = mx + b

m = -3/4

b = 1

y = -3/4*x + 1

The equation of the line that has a slope (-3/4) and y-intercept 1 is

y = (-3/4)x + 1.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = -3/4

y-intercept = 1

The equation of a line.

y = mx + c

y = (-3/4)x + 1

Thus,

y = (-3/4)x + 1 is the equation of the line.
