Answer:
7 games
Step-by-step explanation:
Ricardo has 2 cases with x number of games in each. This means 2x is the amount of video games in both. He gives away 4. He now has 2x-4 and has 10 left. This is 2x-4=10. Solve for x.
2x - 4 = 10
2x = 14
x=7
12. 32
6*2. 8*4
3*2*2. 4*2 2*2
2*2*2*2*2
Do the rest of the math yourself lol
Answer: ok i got this. 9.79 cm^2 ???
Its really hard to understand the numbers shown in the picture or even written in the question ≡(▔﹏▔)≡
Slope-intercept form is <em>y = mx + b</em> where m is the slope and b is the y-intercept. (the value of y when x = 0)
To find the slope, use the slope formula,
, where (x¹, y¹) and (x², y²) are your two points.
For (-2, 6) and (2, 14):
As a fraction, we would write the slope 2/1, but dividing by 1 is redundant when writing the actual equation.
Since slope is rise over run, we can interpret this slope as <em>"when y changes by 2, x changes by 1 (and vice versa)"</em>
Let's take one of our points, how about (-2, 6), and find our y-intercept from this.
We want to add 2 to x. According to our slope, this means adding 4 to y.
Our y-intercept is at (0, 10), with the value we put into our equation b = 10.
Final equation:
y = 2x + 10
The answer is 17 and 9
Because 13-4=9 13+4=17
