Underroot of x = 12

x can be Option A because underroot of 125 is more than 12.
x cannot be option b because the under root of 144 is 12 and this wont be an inequality.
x cannot be Option C or D as the under root will be smaller
X is Option E because the under root will be more
X is not F as the under root of 143 is less
Option A and E

Problem: Square root of x<12

To solve that, we square both size, x<144

Choices that is less than 144 are the correct answers

Confused on the steps and I need help

Answer:

3) y = -1

5) x = -14

Step-by-step explanation:

The first step is to recognize that the equation describes a vertical line in problem 3 and a horizontal line in problem 5. The perpendicular to a vertical line is a horizontal line, and vice versa.

3. To make the desired horizontal line go through the point (-8, -1) the y-value of the line must match that of the point:

y = -1

5. To make the desired vertical line go through the point (-14, 81), the x-value of the line must match that of the point:

x = -14

Which is the additive inverse of the complex number -8+3i?

lawyer [7]

The additive inverse of a complex z is a complex number $-z,$ so that

$\mathsf{z+(-z)=-z+z=0+0i=0}$

Finding $-z:$

$\mathsf{z=-8+3i}\\\\\\ \mathsf{z+(-z)=0+0i}\\\\\ \mathsf{-8+3i+(-z)=0+0i}\\\\ \mathsf{-z=0+0i+8-3i}\\\\ \mathsf{-z=(0+8)+(0i-3i)}\\\\ \boxed{\begin{array}{c}\mathsf{-z=8-3i} \end{array}}\qquad\checkmark$

A child bus ticket costs $0.40 and an adult’s ticket costs $0.70. A group of 11 individuals pays $5.90 for their fare.

oee [108]

Here we have a system of equation like this:
$A+B=11\\
0.4A+0.7B=5.9$
from the first equation we get:
$A=11-B$
Substitute in the second equation we get:
$0.4(11-B)+0.7B=5.9\\4.4-0.4B+0.7B=5.9\\0.3B=1.5\\B= \frac{1.5}{0.3}=5$
Substitute i the first equation again we get:
$A=11-B=11-5=6$
We deduce that:
$A > B$ A is bigger than B.
