To find the mean or the avg you add up all the numbers you have and then divide by how many numbers you added together in this case 5
so the mean is 22, hope this helped you!
Answer:
The equation for this sentence is: 9 = 2(4y)
Hi there!
To start, we can use the two points to find the slope using the formula y2-y1/x2-x1. Just sub in the points and solve!
-0.5-0.5/3-(-3)
-1/6
Sub that into the formula y-mx+b for m, and use one of the points for x and y - solve for b and you get your equation.
y=mx+b
y=-1/6x+b
0.5=-1/6*-3+b
0.5=-0.5+b
0.5+0.5=b
b=1
Therefore your equation is y=-1/6x+1
Hope this helps!
Answer:
380; 5% increase is 399
39; 33% decrease 26.13
48; 15% increase 55.2
3,000; 325% increase 12,750
160; 20% decrease 128
Step-by-step explanation:
If you would like to solve the equation 2 * x^2 + 8 * x = x^2 - 16, you can calculate this using the following steps:
<span>2 * x^2 + 8 * x = x^2 - 16
</span><span>2 * x^2 - x^2 + 8 * x + 16 = 0
</span>x^2 + 8 * x + 16 = 0
(x + 4) * (x + 4) = 0
x = - 4
<span>The correct result would be x = - 4.</span>
