What value of b will cause the system to have an infinite
kvasek [131]

Hi there!

The way that an infinite number of solutions is achieved is when the two equations, when solved together, get an answer which is just a number equal to the same number. To do this, first substitute 6x-b in for y in the second equation.

-3x+\frac{1}{2}(6x-b)=-3

-3x+3x-\frac{1}{2}b=-3

-\frac{1}{2}b=-3

Now, we see that b needs to be equal to -3 when multiplied by -1/2. When both sides are divided by -1/2, b becomes equal to 6. Thus, b must be 6.

Check work:

6x-6=y

-3x+\frac{1}{2}(6x-6)=-3

-3x+3x-3=-3

-3=-3

Thus, as they are equal to each other, the answer is correct. b = 6.

Hope this helps!

8(5-32) equal to and explain <br> please help
Gre4nikov [31]
You would use order of operations: PEMDAS
P(parenthesis) E(exponents) MD(multiplication/division) AS(addition/subtraction)
with MD and AS order doesnt matter.
8(5-32) you would start with inside the Parenthesis for "P" so (5-32)=(-27)
next you would go to the E but because you dont have an exponent you go to the next step with is the "MD" you have multiplication so next would be 8(-27) and 8 multiplied by -27 is: 8(-27)= -216
ANSWER: -216
