I'm not sure what it is
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Let the unknown number be x
Five times the number is expressed as 5x
28 greater than the product of the number and -2 is expressed as;
28 + (-2x)
Equating both expressions
5x = 28 + (-2x)
5x = 28 - 2x
5x+2x = 28
7x = 28
x = 28/7
x = 4
Hence the number is 4
Answer:
y=-6x+48
Step-by-step explanation:
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).
