2x²+7x+3=0

2x²+(1+6)x+3=0

2x²+1x+6x+3=0

x(2x+1)+3(2x+1)=0

(2x+1)(x+3)=0

2x+1=0. x+3=0

2x=-1. x=-3

x=-1/2

Bogdan [553]
The correct question is
<span>Suppose you know that S angle and Y angle are complementary, and that angle S=5(angle Y)- 180 degrees. What is the value of angle Y?

we know that
</span>S angle and Y angle are complementary
so
S+Y=90-------> S=90-Y------> equation 1
and
S=5Y-180----> equation 2

equate equation 1 and equation 2
90-Y=5Y-180------> 5Y+Y=180+90-----> 6Y=270-----> Y=45°
S=5*45-180-----> S=45°

the answer is
Y=45°

What is 1+1×80+5-23+456×47+56784-2647= Put the answer in Standard form
slamgirl [31]

Answer:

7.5632 *10^{4}

Step-by-step explanation:The simplification

1+1×80+5-23+456×47+56784-2647

=1+80+5−23+(456)(47)+56784−2647

=81+5−23+(456)(47)+56784−2647

=86−23+(456)(47)+56784−2647

=63+(456)(47)+56784−2647

=63+21432+56784−2647

=21495+56784−2647

=78279−2647

=75632

Converting 75632 into standard form 7.5632 *10^{4}

Solve the system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent.
Vesnalui [34]
I think this is inconsistent because I got "y" by itself in both equations and not the slope nor the base number matched.
