Answer:
A is correct ..............
Answer:
B) −2
Explanation:
When x is positive then y is positive integer.
When x is negative then y is negative integer.
<u>For Option A</u>
- y = -1 [x is negative so is y]
<u>For Option B</u>
- y = 1 [<u>x is negative</u> but <u>y is positive</u>]
<u>For Option C</u>
- y = 7 [x is positive so is y]
<u>For Option D</u>
- y = 9 [x is positive so is y]
Answer:
x + 2x + 2x + 2 + 4x + 4 = 42
Step-by-step explanation:
Let us assume the number of orange buttons be x
So, the grey buttons be 2x
The white buttons would be 2x + 2
And the black buttons be 2(2x + 2) i.e. 4x + 4
Also the total is 42 buttons
So, the equation is
x + 2x + 2x + 2 + 4x + 4 = 42
Answer:
The first set is a set of linear equations.
The way to figure this out is pretty easy. If you want to see it visually, go search up desmos graphing calculator and put in these equations.
A linear equation is a function that has a constant slope, meaning that the rate it increases or decreases will never change. The first one is a set of linear equations because it is 2 equations with constant slopes, meaning that the slopes will never change no matter what y and x are.
The second set is not, because while the first equation is linear, the second is an inequality. While it is a straight line, it doesn't count as a linear equation.
The third set, both equations have exponents on the x, which means that the slope will change depending on x. This means that both of these are not linear equations.
The only set that is a linear set is the one that has only linear equations.
