m = 
y - = m( x - ) point - slope form of a line.
y = mx + b slope- intercept form of a line.
~~~~~~~~~~~~~~~~~
( - 2, - 7 )
( 0, - 4 )
m = 
= 
y - ( - 4 ) = ( x - 0 )
y + 4 = x
<em>y = </em><em> x - 4</em> slope- intercept form
<em>3x - 2y = 8</em> standard form
Combine like terms.
12x^4 + 4x^3 - x^2
Answer:
x= -2
Step-by-step explanation:
7x+26+5x=2
7x+5x=12x
12x=2-26
12x= -24
(divide both sides by 12)
x= -2
D, it is the correct answer
Answer: x=25
solution:
we know that
The triangle external angle theorem states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles
In this problem:
m∠9=m∠7+m∠8
substitute the given values:
(6x-20)°=30°+4x°
now solve for x:
6x-4x=30+20
2x=50
x=25 which is the final answer:)
