−5b+4(1+6b)<−110
Step 1: Simplify both sides of the inequality.
19b+4<−110
Step 2: Subtract 4 from both sides.
19b+4−4<−110−4
19b<−114
Step 3: Divide both sides by 19.
19b/19 < −114/19
answer: b<−6
The value of f(8) and x is 28 and 4 respectively
<h3>Function and values</h3>
From the coordinate point (x, y), we can use the coordinate points (0,4) and (4,8)
For the sequence 0, 4...
f(x) = a +(x-1)d
f(x) = 0 + (x-1)(4)
f(x) = 4x-4
If the value of x is 8
f(x) = 4(8) - 4
f(8) = 32 -4
f(8) = 28
If the value of f(x) is 12
12 = 4x-4
16 = 4x
x = 4
Hence the value of f(8) and x is 28 and 4 respectively

Answer:
Step-by-step explanation:
f(x) = x^2
reflect along the x-axis
g(x) = -x^2
expand vertilcally by a factor of 1/3
g(x) = (-1/3) x^2
move horizontally 4 units to the left
g(x) = (-1/3) (x+4)^2
hope this helps
Answer:
3x^4 + 7x^3 - 5x^2 + 8x - 13
Step-by-step explanation:
(3x^4 + 7x^3 - 9) - (5x^2 - 8x + 4) =
The negative sign to the left of the second set of parentheses changes every sign inside the parentheses.
The first set of parentheses is unnecessary, so we just drop it.
= 3x^4 + 7x^3 - 9 - 5x^2 + 8x - 4
Now we combine like terms.
= 3x^4 + 7x^3 - 5x^2 + 8x - 13
