The difference between 4 and the product 6x is 40

mote1985 [20]

This would be written as 4-6x=40, then you subtract 4 from both sides to get -6x=36 which simplifies to x=-6.

Find y. Question attatched.

ICE Princess25 [194]

Answer: y=4

Step-by-step explanation:

We have a khown angle wich is 30 degree .

Cos 30 = root square of 3 /2

So root sqaure of 3/2 = 4 root square 3 / x

X= 4 r.sq 3 / r.sq 3/2 = 8

So we just need to apply the pythagorian theorem

X^2= y^2+ 48

64 = y^2 +48

Y^2 = 16

Y=4

If a b and c are three different numbers which of the following equations has exactly one solution?

Mrrafil [7]

Option B is correct.

Step-by-step explanation:

We need to identify which of the following equations has exactly one solution.

We will solve each equation to find the answer

A. $ax+b=ax+b$

Solving and finding value of x:

$ax+b=ax+b\\ax-ax=b-b\\0=0$

This equation has infinite number of solutions because both sides are equal to 0

B. $ax=bx+c$

Solving and finding value of x:

$ax=bx+c\\ax-bx=c\\x(a-b)=c\\x=\frac{c}{a-b}$

This equation has exactly one solution

C. $ax+b=ax+c$

$ax+b=ax+c\\ax-ax=c-b\\0=c-b$

This equation has no solution because both sides are not equal.

So, Option B is correct.
