Hey there :)
( 5y + 9 )( 6y - 1 )
We need to use FOIL to expand, that is
First Terms
Outer Terms
Inner Terms
Last Terms
First Outer Inner Last
( 5y )( 6y ) + ( 5y )( - 1 ) + 9 ( 6y ) + 9 ( - 1 )
30y² - 5y + 54y - 9
Combine, if any, the like-terms
30y² + 49y - 9
Answer:
y = -2x + 3
Step-by-step explanation:
y2 - y1/ x2 - x1
7 - (-5) / -2 - 4
-2
The slope is -2.
To find the y-intercept, you need to plug the coordinates into the equation.
y = -2x + b
7 = -2(-2) + b
7 = 4 + b
3 = b
y = -2x + 3
Answer:
improper fractions are mixed numbers that can be multiplied by bottom to top like 2/4 x 4/5 so is 2 and 4 from 2/4 and 4/5 you can also do bottom to top like 2 x 5=10 and 4 x 4= 16 now you can add 10 + 16=26
Use this formula a2 − b2 = (a + b)(a − b)
<span>(x+1)^2-(x-1)^2 in this case, a = x+1, b = x-1</span>
<span>= [(x+1) + (x-1)] * [(x+1) – (x-1)]</span>
=(x +1 + x – 1) *(x +1 – x +1)
= 2x * 2
<span>=4x</span>
