Answer: The text also states, “And her friends told her afterwards that she had spoken in a very loud voice, not shouting, just a very loud voice” (p.2). This proves that Celeste took a risk standing up to the teacher in a firm voice; her actions show that she believed the risk of getting in trouble was worth it to stop the Teacher’s unfair punishment.

State the value of the discriminant for the equation,<br> 3x^2 + 7x + 3 = 0

Irina-Kira [14]

Answer: 13

Step-by-step explanation:

If you remember the quadratic equation formula;

$x=\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}$

You can easily extract what is under the root to find the discriminant.

$b^2-4ac=?\\$

a = 3

b = 7

c = 3

$(7)^2-4(3)(3)\\49-36=13$

Use the figure to find the measure of angle 1. *

QveST [7]

Answer: angle 1 = 110 degrees

This is because angle 1 and the red 110 degree angle are corresponding angles.

They correspond to one another due to the fact they are both in the southwest corner of each 4-corner angle configuration (which is the result of crossing two lines)

Corresponding angles are congruent only when we have parallel lines like this.
