Answer:
m
=
4
Step-by-step explanation:
Given -

x
−
2
y
=
14
It is in the form
a

+
b
y
=

If a linear equation is in this form, then -
It slope is
−

The equation is 30x + 25
since the x is with the 30, that would be the cost per lesson, because you would multiply 30 by the number of lessons(x)
Let's say you are given the equation 4(x+5). What you must do is distribute the 4 to everything inside the parenthesis. What this means is that you multiply everything inside the parenthesis by the number outside the parenthesis (in this equation that would be 4). For example, the equation 4(x+5) would distribute as (4*x)+(4*5). This would then become 4x+20.
Answer: 2+(-35)
Step-by-step explanation:
When finding which equation is equivalent to the one you have. It's best to find what your equation's answer is.
2-35 equals -33
So we need to find the other equation that equals the same, for that's "equivalent". When you're trying to add a positive and a negative together, you're actually subtracting them because of the negative. In which your answer would end up as a negative, and if the negative is the greater number, you subtract it that way. Sometimes it's good to use a number line so you don't mess up if you're gonna go that way.
The equation of a circle is defined by (x – h)² + (y – k)² = r² with the center being at (h, k) and with radius r. So we have r² = 16. So the radius equals 4. Hope that helps.
