Each two digit number has two numbers (duh!). Let's allow the tens digit to be x and the units digit to be y. Tens digit is 3 less than the units digit: x = y-3 Original number is 6 more than 4 times the sum of the digits: 10x+y-6 = 4x + 4y This gives us simultaneous equations!First let's clear the mess: 1. x= y-32. 6x-3y=6 Substitute 1 into 2: 6(y-3) -3y =66y - 18 - 3y = 6
3y = 24y = 8 Our units digit is 8 Substitute y= 8 into 1. x = y - 3x = 5 Our tens digit is 5 Therefore, our number is 58
Yep! Good job, you did it correctly.
Your y-intercept is equal to the constant of the equation (y-int = -2). Your movement/direction (or rise over run) is equal to the variable. Since your variable is x (which can also be written as 1x) means you move up one and over one (rise over run). This is because 1/1 is equal to 1.
Well first, you have to know the distance formula. You plug the coordinates into it and you get the answer.

√1² + -7² = d
d = 7.1
Answer:20
Step-by-step explanation:
I got it right on my test
Answer:
x < -6
Step-by-step explanation:
-3x > 18
Divide both sides by -3
-3x/-3 < 18/-3
Note : in inequalities when both sides are divided by negative or minus, the inequality sign changes.
Therefore
x < -6
There's no difference as the equations are the same
