the answer is 8x-4 because
3x+−5+5x+1
=(3x+5x)+(−5+1)
=8x+−4
Answer:
-3 </= x < 2
negative 3 is less than or equal to x which is less than 2
Step-by-step explanation:
The top graph shows x is less than 2. The circle is open, so the solution excludes the number 2. (If it was solid, it would be less than or equal to 2)
The second graph shows x is greater than or equal to 3. (the circle is filled in)
So if x is greater than or equal to 3, then 3 is less than or equal to x

Answer:
6
Step-by-step explanation:
maximum calories in a day = 540
no. of calories from the dog food = 320 x 1 ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
= 480
∴ she can have: 540 - 480
= 60 calories to stay inside calorie range
no. of new treats she can have = 60 ÷ 10
= 6
Hope this helps!
Answer:
Not possible to find out area
Step-by-step explanation:
Given is an exponential function as
and we have to find the area to the left of e above x axis under the curve.
Using integrals, we find area =
![\int\limits^e_{-\infty} e^{-x} \, dx\\=-e^{-x}](https://tex.z-dn.net/?f=%5Cint%5Climits%5Ee_%7B-%5Cinfty%7D%20%20e%5E%7B-x%7D%20%20%5C%2C%20dx%5C%5C%3D-e%5E%7B-x%7D)
substitute limits
When we substitute -infinity we get e^infty which is again infinity
Hence finding out area is not possible.
The integral of area diverges.
