X = 3

x = -1 /3

3x = -1 

3x + 1 = 0

x - 3= 0 

(3x+1) (x-3) = 0

3x^2 -9x +x - 3 = 0

3x^2 - 8x - 3 = 0

The triangles are similar.
Natalija [7]
X=23

I say this because you can see that the scale factor is 3 due to just visually scaling both the long and short leg from the original triangle to the dilated triangle. Dividing 39 by 3 is 13, and doing it in reverse. Adding 10 would equal 23, the initial value. So that'd be the missing value.

Complete the recursive formula of the arithmetic sequence -15, -11, -7, -3,...−15,−11,−7,−3,...minus, 15, comma, minus, 11, comm
o-na [289]

Answer:

c(1) = -15

c(n) = c(n - 1) + 4

Step-by-step explanation:

Given arithmetic sequence is,

-15, -11, -7, -3...........

Common difference between each successive and previous term is,

d = -11 - (-15)

  = -11 + 15

  = 4

Since recursive formula of the arithmetic sequence is represented by,

a₁ = First term of the sequence

a(n) = a(n - 1) + d

where a(n) is the nth term and a(n-1) is the previous term of the nth term.

Form the given sequence,

c₁ = -15

c(n) = c(n - 1) + 4

The sum of 42 and a number x is 51
n200080 [17]

Answer:

x = 9

Step-by-step explanation:

"The sum of 42 and a number x is 51" in "mathy" words:

42 + x = 51

Then, subtract both sides by 42:

42 + x - 42 = 51 - 42

So

x = 9
