Answer:

f(n) = 4(n-1) + 7

First term

f(1) = 4(1-1) +7 = 0 + 7 = 7

Second term

f(2) = 4(2-1) + 7

= 4(1) + 7 = 4 + 7 =11

Third term

f(3) = 4(3-1) + 7

= 4(2) + 7

= 8 + 7 = 15

Therefore the first three terms of the sequence are 7, 11 and 15.

Hope this helps

In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10. What is the value of x?

Stels [109]

Answer: The value of x= 18

Step-by-step explanation:

Given: In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10.

The sum of all angles of a triangle is 180°.

Therefore, in triangle EFG

∠E + ∠F +∠G= 180°

⇒ 8x-16 +x+8+ 2x-10 = 180

⇒ 11x-18= 180

⇒ 11x = 180+18

⇒11x=198

⇒ x= 18 [Divide both sides by 11]

Hence, the value of x= 18

Quadrilateral FGHI is similar to quadrilateral JKLM. Find the measure of side JK

Stells [14]

Answer:

Heyyyy!!

The answer is 66.9

please read the explanation... it will help... I promise

Step-by-step explanation:

Okay... Here we go...

The context mentions that the two quadrilaterals are similar... meaning their sides are proportional...

So... you basically have to find the scale factor...

(the math itself is easier than the explanation...

51/16 = 3.1875 (that is the number we multiplied the sides of quadrilateral FGHI to get quadrilateral JKLM...

so to get side JK all you have to do is multiply that scale factor by side FG... which after the use of a calculator results in 66.9 (i rounded, and used a calculator... lol)

but yeah... i hope this helps...

Create a number pattern that follows the rule

vazorg [7]

Answer:

The pattern form is 8,15,34,71 which follows the rule $x^3+7$

Step-by-step explanation:

Given : Rule $x^3+7$

To find : Create a number pattern that follows the rule. Use at least three terms in the pattern ?

Solution :

Rule $x^3+7$

Put n=1,

$x^3+7=(1)^3+7$

$x^3+7=1+7=8$

Put n=2,

$x^3+7=(2)^3+7$

$x^3+7=8+7=15$

Put n=3,

$x^3+7=(3)^3+7$

$x^3+7=27+7=34$

Put n=4,

$x^3+7=(4)^3+7$

$x^3+7=64+7=71$

The pattern form is 8,15,34,71 which follows the rule $x^3+7$

This has two answers so ya give um to me

alexandr1967 [171]

Let's separate this absolute value equation into two different equations.

x + 1 = 3.

Subtract 1 from each side

x = 2.

x + 1 = -3

Subtract 1 from each side

x = -4

The two solutions are x = 2 and x = -4
