Answers

Answer 1

Answer:

[tex]n_x = -4n_{x-1}\\[/tex]

where [tex]n_1[/tex] = 2

Step-by-step explanation:

512/-8 = -64

difference of n = 3

[tex]\sqrt[3]{64} = 4[/tex]

[tex]n_x = -4n_{x-1}\\[/tex]

where [tex]n_1[/tex] = 2

Use substitution to solve the following system of equations. 4x – 13y = -12 AND X = 2y - 8 ​

Answers

Answer:

y=5/4=0.8

Step-by-step explanation:

(4×2y−8)−13y=−12

Multiply 4 and 2 to get 8.

8y−8−13y=−12

Combine 8y and −13y to get −5y.

−5y−8=−12

Add 8 to both sides.

−5y=−12+8

Add −12 and 8 to get −4.

−5y=−4

Divide both sides by −5.

y=−5−4

Fraction −5/−4 can be simplified to 5/4 by removing the negative sign from both the numerator and the denominator.

y=5/4

A function is when every input has one output.

Easiest way is to do the "vertical line test" and "horizonal line test."

Basically you draw a vertical line and a horizontal line.

If either line passes through more than one point, then it is not a function.

The only one that passes them is B, the line.

Given the two triangles shown, find the value of x

Answers

Answer: x = 150/6 = 25

Step-by-step explanation:

Here is the information shown in the diagram: in triangle ABC, Angle A = 68, Angle C = 38, AB = 6, and BC = 10. In triangle DEF, Angle D = 38, Angle E = 74, EF = 15, and DE = x.)

The value of x is (Choose...4, 11, 12, 19, 20, 25).

To solve this, we notice that the sum of the angle measures mentioned is 68 + 38 + 74 = 180. Thus Triangles ABC and FED are similar by AA Similarity. It remains only to set up the proportion:

DE/CB = EF/BA

x/10 = 15/6

x = 150/6 = 25

The value of x in the triangle is 25

The triangle are similar.

What are similar triangles:

Similar triangles are only different in sizes. There corresponding angles are equal and all corresponding side have the same ratios.

Therefore, let's find the value x by establishing the proportion below:

ΔABC ≅ ΔFED

AB / FE = BC / ED = AC / FD

6 / 15 = 10 / x

cross multiply

6x = 150

x = 150 / 6

x = 25

Answer:

(a) A trapezoid has only 1 pair of parallel sides but a parallelogram has 2

Step-by-step explanation:

Required

The difference between a trapezium and a parallelogram

The major difference is:

A trapezium has a pair of parallel side, the other sides are not parallel

A parallelogram has 4 sides where opposite sides are parallel (i.e 2 pairs of parallel sides).

Hence, (a) is correct
