2X +12 equals 13 X minus P

1 answer:

4 0

(2x + 3)(x + 5) = x

Reorder the terms:
(3 + 2x)(x + 5) = x

Reorder the terms:
(3 + 2x)(5 + x) = x

Multiply (3 + 2x) * (5 + x)
(3(5 + x) + 2x * (5 + x)) = x
((5 * 3 + x * 3) + 2x * (5 + x)) = x
((15 + 3x) + 2x * (5 + x)) = x
(15 + 3x + (5 * 2x + x * 2x)) = x
(15 + 3x + (10x + 2x2)) = x

Hey can you help me answer this question by giving me the answer?

The value of f(a)=4-2a+6 $a^{2}$ , f(a+h) is $6a^{2} +6h^{2} -2a-2h+12ah$ , [f(a+h)-f(a)]/h is 6h+12a-2 in the function f(x)=4-2x+6 $x^{2}$ .

Given a function f(x)=4-2x+6 $x^{2}$ .

We are told to find out the value of f(a), f(a+h) and [f(a+h)-f(a)]/hwhere h≠0.

Function is like a relationship between two or more variables expressed in equal to form.The value which we entered in the function is known as domain and the value which we get after entering the values is known as codomain or range.

f(a)=4-2a+6 $a^{2}$ (By just putting x=a).

f(a+h)== $4-2(a+h)+6(a+h)^{2}$

=4-2a-2h+6( $a^{2} +h^{2} +2ah$ )

=4-2a-2h+6 $a^{2} +6h^{2} +12ah$

= $6a^{2} +6h^{2}-2a-2h+12ah$

[f(a+h)-f(a)]/h=[ $6a^{2} +6h^{2}-2a-2h+12ah$ -(4-2a+6 $a^{2}$ )]/h

= $(6a^{2} +6h^{2} -2a-2h+12ah)/h$

= $(6h^{2} -2h+12ah)/h$

=6h+12a-2.

Hence the value of function f(a)=4-2a+6 $a^{2}$ , f(a+h) is $6a^{2} +6h^{2} -2a-2h+12ah$ , [f(a+h)-f(a)]/h is 6h+12a-2 in the function f(x)=4-2x+6 $x^{2}$ .

(0,15)(1,19)
slope = (19 - 15) / (1 - 0) = 4

y = mx + b
slope(m) = 4
(0,15)...x = 0 and y = 15
sub
15 = 4(0) + b
15 = b

y = 4x + 15....so ur rule is : F(s) = 4s + 15
