If i could see the paper i prob. could help cause i am really good in scienc and biology
Answer:
x = 4.4
Step-by-step explanation:
I'm going to assume you want to solve for x so here we go.
You need to work backwards for this equation, and whatever you do to the LHS, you do to the RHS.
First, you need to remove the minus 3, which means that on both sides, you add 3. Adding three on the LHS makes the -3 disappear, and adding 3 on the RHS makes the 19 go to a 22.
Your equation is now 5x=22.
Since 5x means 5 × x, to get rid of it, you need to divide 5x by 5. Doing it to the LHS will make the five disappear, and doing it to the RHS will make it go to 22 ÷ 5 which equals 4.4
Therefore, x = 4.4
Answer:
<em>The area of the shaded region is 3.</em>
Step-by-step explanation:
Since point E lies halfway between AB and BC, the area of the shaded region (As) consists of two identical triangles with base equal to AB and height equal to half the measure of BC:
![A_s=2 * A_t](https://tex.z-dn.net/?f=A_s%3D2%20%2A%20A_t)
Where At is the area of each triangle.
![\displaystyle A_t=\frac{AB*BC/2}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A_t%3D%5Cfrac%7BAB%2ABC%2F2%7D%7B2%7D)
![\displaystyle A_t=\frac{AB*BC}{4}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A_t%3D%5Cfrac%7BAB%2ABC%7D%7B4%7D)
We know AB=3 and BC=2, thus:
![\displaystyle A_t=\frac{3*2}{4}=\frac{6}{4}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A_t%3D%5Cfrac%7B3%2A2%7D%7B4%7D%3D%5Cfrac%7B6%7D%7B4%7D)
Simplifying:
![\displaystyle A_t=\frac{3}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A_t%3D%5Cfrac%7B3%7D%7B2%7D)
Finally:
![\displaystyle A_s=2 * \frac{3}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A_s%3D2%20%2A%20%5Cfrac%7B3%7D%7B2%7D)
![A_s=3](https://tex.z-dn.net/?f=A_s%3D3)
The area of the shaded region is 3.
Note the area of the shaded region is half the area of the rectangle.
Answer:
it's d
Step-by-step explanation:
multiply 0.31 by the amount of minutes used (27) and add the flat fee to it.
0.31×27+(0.57)= 8.94
f(x)= -2 (x - 2) ( x - 4)
if x=2 ⇒ f(x)=y=0 ⇒ graph of f(x) intercept x axis in (2,0)
if x=4 ⇒ f(x)=y=0 ⇒ graph of f(x) intercept x axis in (4,0)
if x=0 ⇒f(x)= -2 *(-2)*(-4)= - 16 ⇒ graph of f(x) intercept y axis in (0,- 16)
⇒ f(x)= -2 (x - 2) ( x - 4) is the answer
