Help with geometry!!

Mathematics
1 answer:
Morgarella [4.7K]3 years ago
4 0

Answer:

y = x

Step-by-step explanation:

Slope-intercept form is the form that looks like

... y = mx + b . . . . . . for slope m and y-intercept b

The line connecting points D and E has slope 1 and y-intercept 0, so the equation is ...

... y = 1·x + 0

... y = x . . . . . . without the identity elements

_____

<em>Comment on the marked choice</em>

The choice that is marked is the equation in <em>point-slope form</em> using the point E (4, 4). That is not the form requested by the problem.

The lines are parallel.

In order to figure this out, let's start off by simplifying both equations as much as we can:
2y = 16 + 4x
Divide by 2
y = 2x + 8

Remember that the slope of that equation is '2' since 'm' in the equation y = mx + b represents slope.

Simplify the next equation:
6y - 30 = 12 x
6y = 12x + 30
Divide by 6:
y = 2x + 5

As you can tell, this line also has a slope of 2.
Parallel lines is defined as two lines that have the same slope. Knowing this, we can infer that these two lines are parallel.

If I have a triangular prism with the length of 9mm, the base of 6.6 mm, and the height 4 mm or 5.2 mm. What would be the surfac
Lelu [443]

The surface area of triangular prism is 117.12 mm²

<u>Explanation:</u>

Base side, a = 9 mm

Base side, b = 6.6 mm

Base side, c = 5.2 mm

Height, h = 4 mm

Total surface area = ?

We know,

Surface area, A = 2 Ab ( a+b+c) h

Ab = √s(s-a) (s-b) (s-c)

s = a+b+c/2

Solving for A

A = ah + b h + ch + 1/2 √ -a⁴ + 2(ab)² + 2(ac)² - b⁴ + 2 (b c)² - c⁴

A = 9.4 + 6.6 X 4 + 5.2 X 4 + 1//2 √ -9⁴ + 2(9 X 6.6)² + 2(9 X 5.2)² - (6.6)⁴ + 2 (6.6 X 5.2)² - (5.2)⁴

A = 117.12 mm²

Therefore, the surface area of triangular prism is 117.12 mm²

Figure ABCD is a parallelogram
Nadya [2.5K]

The first thing we must do for this case is to find the relationship between the variables.

We have then:

AB = DC\\4y - 2 = 2y + 6

From here, we clear the value of "Y":

4y - 2y = 6 + 2\\2y = 8

y = \frac{8}{2}\\y = 4

On the other hand we have:

AD = BC\\3x - 1 = 2x + 2

From here, we clear the value of "x":

3x - 2x = 2 + 1\\x = 3

Then, replacing values we have:

AB = DC = 4y - 2 = 4 (4) - 2 = 16 - 2 = 14\\AB = DC = 14

On the other hand:

AD = BC = 2x + 2 = 2 (3) + 2 = 6 + 2 = 8\\AD = BC = 8

Finally, the perimeter is given by:

P = AB + DC + AD + BC

Substituting values we have:

P = 14 + 14 + 8 + 8\\P = 44

Answer:

the perimeter of ABCD is:

44 units
