Hello,
Here is your answer:
The proper answer to this question is "5".
Here is how:
All you have to do divide 125 by 3!
5*5*5=125
Exponent form:
=5^3
Your answer is 5!
If you need anymore help feel free to ask me!
Hope this helps!
The height would be 3.7
Because it's an isosceles triangle, you and I know that the sides are 4 and the base is 3. We also know that to find the height we need to use Pythagorean's theorem. Therefore, h square + 1.5 square = 4 square (we get 1.5 from dividing 3 to get the base). Solve it and the height is 3.7
Answer:
x ≈ 6.6 cm
Step-by-step explanation:
The Pythagorean theorem applies. The sum of the squares of the legs of this right triangle equals the square of the hypotenuse:
x^2 + 13.5^2 = (x+8.45)^2
x^2 +182.25 = x^2 +16.9x +71.4025
110.8475 = 16.9x . . . . . subtract x^2 +71.4025
6.559024 = x . . . . . . . .divide by 16.9
The value of x is about 6.6 cm.
= (-6+2/2, -2-4/2)
= (-4/2, -6/2)

If you graph y=7x-9 and y=3x-1 the two lines will intersect at one point. That is how you graphically "solve" the system of equations.
Both of these lines are of the form y=mx+b where m is the slope and b is the y-intercept.
So for y=7x-9, the slope is 7 and the y-intercept is -9
For y=3x-1, the slope is 3 and the y-intercept is -1
....
The solution for this system occurs when both coordinates are equal to each other so we can say:
7x-9=3x-1 subtract 3x from both sides
4x-9=-1 add 9 to both sides
4x=8 divide both sides by 4
x=2, making y=3x-1 become:
y=3(2)-1=6-1=5, so the solution to the system of equations is:
(2,5)
