answer is 7.
since the unkown number is multiplied by itself what we need to do to get out answer is to work backwards. Thats where we cube root 343 to get 7.(∛343 =7)
Answer:
y= 1/3x
Step-by-step explanation:
1.Plug the points into the slope formula- m=y2-y1/x2-x1.
So M=3-(-3)/9-(-9)
2.Solve: M=6/18
3.Simplify: M=1/3
4.Input into y=Mx+b
y=1/3x+b
<em>The x and y won't be changed for this equation.</em>
5.Plug in one of the points into the new equation
For (9,3): 3=1/3*9+b so B=0 because 1/3*9=3 which is what we want.
5.5 Or you can do it by solving for b: b=3-(1/3)(9)=0
6. Therefore B=0
7. So the end equation is y=1/3x
Answer:
Given - A rectangle whose area is 1 2/5 m^2
- length is 4/5 m
To find - Length of rectangle
Solution -
1 2/5 = 7/5 m^2
Let the length be X
Area of rectangle= Length × Breadth
7/5 = X × 4/5
7/5 × 5/4 = X
7/4 = X
Length of rectangle= 7/4
