Answer:

x = 15/4

Step-by-step explanation:

4 + 1 - 3x + 10 = x

Combine like terms on the left side.

15 - 3x = x

Add 3x to both sides.

15 = 4x

Switch sides.

4x = 15

Divide both sides by 4.

x = 15/4

Answer:

$\frac{3-2i}{1+4i}=\frac{11}{17}-\frac{10}{17}i$

Step-by-step explanation:

$\frac{3-2i}{1+4i}$ <-- Given

$\frac{3-2i}{1+4i}*\frac{1-4i}{1-4i}$ <-- Multiply by the conjugate of the denominator as a factor of 1

$\frac{(3-2i)(1-4i)}{(1+4i)(1-4i)}$

$\frac{(3)(1)+3(-4i)-2i(1)-2i(4i)}{(1)(1)+1(-4i)+4i(1)+4i(-4i)}$ <-- Use the Distributive Property and FOIL

$\frac{3-12i-2i-8i^2}{1-4i+4i-16i^2}$

$\frac{3-10i-8i^2}{1-16i^2}$

$\frac{3-10i-8(-1)}{1-16(-1)}$ <-- Rewrite $i^2$ as $-1$

$\frac{3-10i+8}{1+16}$

$\frac{11-10i}{17}$

$\frac{11}{17}-\frac{10}{17}i$ <-- Rewrite in $a\pm bi$ form

Ok so you put I = 250 x .0285 x 3 and it gives you 21,375 then you add 21,375 with 250 and it gives you 21,625 that world be your answer

Describe the transformation relative to the parent function. f(x)=(9x)^4. Correct answer will get brainliest

Ber [7]

If you start from the parent function $f(x) = x^4$ , the only transformation performed is $f(x) \to f(9x)$ . In fact,

$f(x) = x^4 \implies f(9x) = 9x^4$

In general, a transformation like $f(x) \to f(kx)$ results in a horizontal stretch. If k>1, the function is compressed, if 0<k<1, the function is streched. If k is negative, the function is reflected around the y axis, and then you apply the logic just described.
