Simplify the expression by combining like terms: x + 7x

Aneli [31]3 years ago

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Soon after taking an aspirin, a patient has absorbed 320 mg of the drug. after 3 hours, only 40 mg remain. find an exponential m
Anastaziya [24]
The equation will be of the form:
A(t)= A_{0} e^{rt}
where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:
40=320e^{3r}
Rearranging and taking natural logs of both sides, we get:
ln\ 0.125=3r
r=\frac{ln\ 0.125}{3}=-0.693
The required model is:
A=A _{0} e^{-0.693t}

Each picture shows a figure and its reflection. Which picture shows the line of reflection?
nikitadnepr [17]

Answer:

Bottom left

Step-by-step explanation:

The point of reflection is the bottom left one because when reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line. The fixed line is called the line of reflection.
