If I remember how to properly do matrices the answer should be:
-15 10 6
30 25 6
-15 0 16
Answer:
y=x/3
Step-by-step explanation:
this is because y=1 and x=3 so y/x=1/3=x/3
Answer:
It is impossible to tell because the sample is not randomly selected
Step-by-step explanation:
The survey here comprises of white male voters and does not cover the entire demographic. The poll is not comprised of female voters and non-white electorate. Therefore, nothing can be inferred by a sample limited to a certain population group.
Answer:
-(1/4)
Step-by-step explanation:
Divide 2 by -8
Answer:
m∠T = 79°
m∠V = 14°
Step-by-step explanation:
Given
As the sum of measures of the angles is 93°.
so
m∠T + m∠V = 93°
(2x + 85)° + (5x + 29)° = 93°
Remove parentheses


Subtract 114 from both sides

Simplify

Divide both sides by 7

simplify

Determining m∠T
m∠T = (2x + 85)°
substitute x = -3
m∠T = (2(-3) + 85)°
= -6 + 85
= 79°
Thus, we conclude that m∠T = 79°
Determining m∠V
m∠V = (5x + 29)°
substitute x = -3
m∠T = (5(-3) + 29)°
= -15 + 29
= 14°
Thus, we conclude that m∠V = 14°
<u>VERIFICATION:</u>
m∠T + m∠V = 93°
substitute m∠T = 79° and m∠V = 14°
79° + 14° = 93°
93° = 93°
