For the function f(x)=5x2−5x, evaluate and simplify.

Answer:

10x -5 +5h

Step-by-step explanation:

Use the function definition with the given arguments.

$\dfrac{f(x+h)-f(x)}{h}=\dfrac{(5(x+h)^2-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{(5(x^2+2hx+h^2)-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{5x^2+10hx+5h^2-5x-5h-5x^2+5x}{h}=\dfrac{10hx-5h+5h^2}{h}\\\\=\boxed{10x-5+5h}$

4.a) 2x=7*3

2x=21

x=21/2 OR

x=10.5

4.b)5x=25*6

5x=150

x=150/5

x=30

4.c)4x=5*14

4x=70

x= 70/4

x=17.5

4.d)4x=9*3

4x=27

X=27/4

X=6.75

4.e)x=0.05*3

X=0.15

4.f)x=0.25*7

X=1.75

4.g)x=0.4*1.5

X=0.6

4.h)x=0.7*2.2

X=1.54

5a)x/7=7-3

X/7=4

X=4*7

X=28

B)2x/5=3+8

2x/5=11

2x=11*5

2x=55

X=55/2

X=27.5

C)2x/3=74-26

2x/3=48

2x=48*3

2x=144

X=72

(I can’t finish all but it is the same method )

alisha [4.7K]

Answer:

One solution

Step-by-step explanation:

7 + 3x - 12x = 3x + 1
7 - 9x = 3x + 1
3x + 9x = 7 - 1
12x = 6
x = 6/12
x = 1/2

It has one solution
