Step-by-step explanation:

Given equation is 7x + 1 = 10x - 9

Shift all variables on LHS and Constants on RHS, changing it's sign.

→ 7x + 10x = -9 - 1

Subtract the values on LHS and RHS.

→ -3x = -10

Shift the number -3 from LHS to RHS.

→ x = -10/-3

Therefore, x = 10/3

<u>Answer</u><u>:</u> Hence, the value of x for the given equation is 10/3.

<u>Verification:</u>

<u>Check</u><u> </u><u>whether</u><u> the</u><u> </u><u>value </u><u>of </u><u>x </u><u>is </u><u>true </u><u>or </u><u>false:</u>

If x = 10/3 then the equation is

7x + 1 = 10x - 9

Substitute x = 10/3 in equation then

→ 7(10/3) + 1 = 10(10/3) - 9

→ (70/3) + 1 = (100/3) - 9

→ (70/3) + (1/1) = (100/3) - (9/1)

Take the LCM of the denominator on both LHS and RHS.

LCM of 1 and 3 is 3.

LCM of 1 and 3 is 3.

Now,

→(70 + 1*3)/3 = (100 - 9*3)/3

→ (70 + 3)/3 = (100 - 27)/3

→ 73/3 = 73/3

LHS = RHS

<u>Hence</u><u>,</u><u> </u><u>verified</u><u>.</u>

Please let me know if you have any other questions.

Answer:

x = 10/3

Step-by-step explanation:

Solve:

  • 7x + 1 = 10x - 9      
  • 1 = 3x - 9                  Isolate x
  • 10 = 3x                     Isolate x
  • x = 10/3                    

x = \boxed{\frac{10}{3}}

F(x)=5x^4 helllllpppppp
Marina CMI [18]

we can use properties of functions to find this out


for f(x)=ax^b


if b is even, then the ends of the function go in the same directions (both up or both down)

if b is odd, then the ends of the function go in different directions (one up and one down)


if a is positive and b is even, then both ends point up

if a is positve and b is odd, then it goes from bottom left to top right

if a is negative and b is even, then both ends point down

if a is negative and b is odd, then it goes from top left to bottom right


given f(x)=5x^4

a=5>0

b=4 which is even

so it has both ends pointing up

bottom right graph is yo answer
