Answer:

x ≤ 3

Step-by-step explanation:

Just divide both sides by 4, the sign stays the same because you're dividing by a positive number

Answer:

its x ≤ 3

Step-by-step explanation:

4x/4 ≤ 12/4 divide both sides by 4

that will give you x≤3.

So, that means x is less than or equal to 3.

Answer:

$f\left(x\right)=x^3-6x^2+3x+10$ is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Step-by-step explanation:

Given the function

$f\left(x\right)=x^3-6x^2+3x+10$

As the highest power of the x-variable is 3 with the leading coefficients of 1.

So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.

solving to get the zeros

$f\left(x\right)=x^3-6x^2+3x+10$

$0=x^3-6x^2+3x+10$ ∵ $f(x)=0$

$Factor\:x^3-6x^2+3x+10\::\:\left(x+1\right)\left(x-2\right)\left(x-5\right)=0$

$\left(x+1\right)\left(x-2\right)\left(x-5\right)=0$

Using the zero factor principle

if $ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

$x+1=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0$

$x=-1,\:x=2,\:x=5$

Therefore, the zeros of the function are:

$x=-1,\:x=2,\:x=5$

$f\left(x\right)=x^3-6x^2+3x+10$ is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Therefore, the last option is true.

Princess bought 7 bracelets that each cost the same amount and pair of earrings that costs $15. The items she bought cost a tota

vladimir2022 [97]

Answer:

Step-by-step explanation:

Your gonna subtract the cost of the pair earrings from the total. 260-15=245, then you will divide 245 by 7. 245/7=35. So each bracelet cost's 35 each.
