Consider the equation 5a = 4+b. What values of a and b make the equation above true?

A a= 5 b = 9

B a=-5 b= -9

С a= -1 b= -9

your answer will be option d

Step-by-step explanation:

look.

5a=4+b

now put the values

of option d

5×-1=4-9

-5=-5 I hope u understand

answer: idk

step-by-step explanation:

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.
