Answer:
x < -3
Step-by-step explanation:
-4x - 10 < 2
-4x < 12 (+10)
-x < 3 (÷4)
x < 3 (+x, -3)
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.

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
30
factors of 6: 6 12 18 24 30
factors of 5: 5 10 15 20 25 30
so its 30
or simply multiple the denominators 6×5=30
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
