Please help!! I don’t know what i’m doing at all

53 + 3g ≤ 65, g ≤ 4

Step-by-step explanation:

To solve for g:

53 + 3g ≤ 65

First, subtract 53 from both sides.

53 - 53 + 3g ≤ 65 - 53

=> 3g ≤ 12

Divide 3 by both sides

=> 3g / 3 ≤ 12 /3

=> g ≤ 4

Therefore, g ≤ 4

Hope this helps :)

g < 4 (gigabytes)

Step-by-step explanation:

Set the equation:

Total cost = (cost per gigabyte x 3) + (flat cost)

64.99 = 3g + 53

Isolate the variable, g. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS:

64.99 (-53) = 3g + 53 (-53)

64.99 - 53 = 3g

3g = 11.99

Divide 3 from both sides to isolate the variable, g:

(3g)/3 = (11.99)/3

g = 11.99/3

g = ~3.996 , or 4 when rounded.

Note: Jose wants to stay below the budget. There is a reason why it is not 4 gigabytes. If it is 4, the number will be higher than the budget allowed. This means that the inequality is:

g < 4

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
