PLS HELP.... If 4x^2 + bx + 9 = 0, where b is the constant, has exactly one solution, what is a possible value of b ?
IgorLugansk [536]
You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12

hope this helps !

Hi could someone just help me with this I'm not sure if i'm doing it correctly.
salantis [7]
Two angles are supplementary when they <span>add up to 180 degrees </span>⇒
m∠1 + m∠2 = 180°
4y + 7 + 9y + 4 = 180
13y + 11 = 180
13y = 180 - 11
13y = 169
y = 169/13
y = 13

m∠2 = 9y + 4 = 9 * 13 + 4 = 121°

Explain why 48 divided by x equal 6 is the same as 48-x-x-x-x-x-x
zhannawk [14.2K]

Answer:

Step-by-step explanation:

Well, they are not the same. For one thing, 48÷x = 6 is an equation.

48-x-x-x-x-x-x is an expression, not an equation.
