Answer:150
Step-by-step explanation: If you see the highest point in the number line. You can see it’s in the middle of of 140 and 160 so it’s 150
Answer:
5 millimetres
Step-by-step explanation:
Area of rectangle = lenght x width
35 = 7 x width
Width = 35/7
Width = 5 mm
Step-by-step explanation:
Find the values of x and y to determine how many solutions.
Use the elimination method. Add both of the equations.
<u>Sum:</u>
<u />![3y=-1](https://tex.z-dn.net/?f=3y%3D-1)
<u>Divide each side by 3:</u>
<u />![\boxed{y=-\frac{1}{3}}](https://tex.z-dn.net/?f=%5Cboxed%7By%3D-%5Cfrac%7B1%7D%7B3%7D%7D)
<u />
<u>Substitute y = -(1/3) into the first equation:</u>
<u />![-5x+6(-\frac{1}{3})=-2](https://tex.z-dn.net/?f=-5x%2B6%28-%5Cfrac%7B1%7D%7B3%7D%29%3D-2)
<u>Multiply:</u>
<u />![-5x-2=-2](https://tex.z-dn.net/?f=-5x-2%3D-2)
<u>Add 2 to both sides:</u>
-5x = 0
We can determine:
![\boxed{x=0}](https://tex.z-dn.net/?f=%5Cboxed%7Bx%3D0%7D)
(0, -1/3)
The system of equations have 1 solution.

Answer:
Step-by-step explanation:
it is increasing in ![]-\infty;3/2]](https://tex.z-dn.net/?f=%5D-%5Cinfty%3B3%2F2%5D)
because this is like
![f(x)=ax^2+bx+c](https://tex.z-dn.net/?f=f%28x%29%3Dax%5E2%2Bbx%2Bc)
where a > 0
and -b/a=3/2
