Answer:
Ax + By = C
A, B and C can be any number--including negative numbers, zero and one! So examples of standard form can look like this:
3_x_ + 7_y_ = 10, where A = 3, B = 7 and C = 10.
Or they can look like this:
x + 5_y_ = 6. In this case, A = 1, B = 5 and C = 6.
Or this:
8_y_ = 9. In this case, A = 0, which is why x does not appear in the equation. B = 8 and C = 9, as you would expect.
And here's one more:
3_x_ − 5_y_ = 12. Here, A = 3, B = −5 and C = 12. Notice that in this case, B is negative five!
The standard form of a linear equation is Ax + By = C, where A, B and C can be any number.
The answer is: " 32a² − 24a − 8 " .
__________________________________________________
Given:
__________________________________________________
(8a − 8)(4a + 1) ; Let us expand this expression using the: "FOIL" method.
___________________________________________________
"FOIL" stands for "<u>F</u>irst terms, <u>O</u>uter terms, <u> I</u>nner Terms, <u>L</u>ast Terms" ;
in that order.
___________________________________________________
Basically:
_______________________________________________________
(a + b)(c + d) = ac + ad + bc + bd ;
in which the:
<u>F</u>irst term is: "ac" ;
<u>O</u>uter term is: "ad" ;
<u>I </u>nner term is: "bc" ;
<u>L</u>ast term is: "bd " .
__________________________________
So; we have (given):
(8a − 8)(4a + 1) ;
__________________________________________________
Let's take the "<u>F</u>irst, <u>O</u>uter, <u> </u><u>I</u>nner, and <u>L</u>ast terms" ; as follows:
__________________________________________________
<u>F</u>: (8a)*(4a) = 32a² ;
__________________________________________________
<u>O</u>: (8a)*(1) = 8a ;
__________________________________________________
<u>I </u>: (-8)*(4a) = -32a ;
__________________________________________________
<u>L</u>: (-8)*(1) = -8
__________________________________________________
Now, let us write out these terms:
__________________________________________________
32a² + 8a − 32a - 8 ;
__________________________________________________
Now, combine the "like terms" in this expression; to simplify:
+ 8a − 32a = -24a ;
__________________________________________________
and rewrite the simplified expression ; which is:
__________________________________________________
32a² − 24a − 8 .
______________________________________________________
Answer:
8
Step-by-step explanation:
The y intercept of a function is found by setting x equal to zero
y = 2x^2 - 5x + 8
y = 2*0 -5*0 +8
y = 8
The y intercept is 8
