Just know that you are smart and that you can do this
no solution
substitute y = 2x + 4 into the other equation
2x - (2x + 4) = 6 ( distribute and simplify )
2x - 2x - 4 = 6 ( add 4 to both sides )
0 = 10 ← not possible
Hence the system has no solution
Hi there!
Let's first determine the x-intercept. When dealing with an x-intercept we must realise the y-coordinates equal 0.

Add 21 to both sides.

Divide both sides by -2.

Therefore, the x-intercept is the point (10 1/2; 0).
--------------------------------------
Now let's continue with the y-intercept, which is easier. When dealing with an y-intercept we must realise the x-coordinates equal 0.

Therefore, the y-intercept is the point (0; -21).
The answer is 454. How to solve? Simple! Just divide 2951 and 6.5.
Answer:
-63
Step-by-step explanation:
Given the expression:

Using the law of indices, this can be written as:

This shows that the value of A is -63
