Write an algebraic expression in simplest form that represents the purchase described below.
Use the information provided:
Cat toy $4
Cat food $12
Litter box $16
Ms. James bought x number of litter boxes and 8 bags of cat food for the animal shelter.
Answers
Answer: 16x+96
Step-by-step explanation:
Since x is the number of litter boxes, you multiply it by the cost of the litter box. It would be 16*x, but you can also phrase it as 16x. For the cat food, you need to multiply 12 by 8. This is because it costs $12, and she bought 8 bags of the food. If you do 12*8, you get 96. In the end, you get 16x+96

Answer:
[tex]\log \:_{10}\left(\frac{1}{2}\right)=-\log \:_{10}\left(2\right)=-0.30102[/tex]
Thus, option A is true.
Step-by-step explanation:
Given the expression
[tex]log\left(\frac{1}{2}\right)[/tex]
[tex]=\log _{10}\left(2^{-1}\right)[/tex]
[tex]\mathrm{Apply\:log\:rule}:\quad \log _a\left(x^b\right)=b\cdot \log _a\left(x\right),\:\quad \:x>0[/tex]
[tex]\log _{10}\left(2^{-1}\right)=-1\cdot \log _{10}\left(2\right)[/tex]
so the expression becomes
[tex]=-1\cdot \log _{10}\left(2\right)[/tex]
[tex]\mathrm{Multiply:}\:1\cdot \log _{10}\left(2\right)=\log _{10}\left(2\right)[/tex]
[tex]=-\log _{10}\left(2\right)[/tex]
substituting the value of log 2 = 0.30103
[tex]\:=-0.30102[/tex]
Thus,
[tex]\log \:_{10}\left(\frac{1}{2}\right)=-\log \:_{10}\left(2\right)=-0.30103[/tex]
Therefore, option A is true.

For the following system,
3x + y = 8
−x − 2y = −10
if you isolated x in the second equation to use the substitution method, what expression would you substitute into the first equation?
−2y + 10
2y + 10
2y − 10
−2y − 10
Answers
Answer:
-2y+10
Step-by-step explanation:
-x - 2y = -10
add 2y to both sides
-x = -10 + 2y OR 2y - 10
divide both sides by -1
x = -2y+10

Question: Reflective symmetry over y = (3/5)x ?
Answer: No

Question: Reflective symmetry over y = (5/3)x ?
Answer: No
================================================
Explanation:
For any parallelogram that's a square, we'll have four lines of symmetry: The two diagonals and two extra lines of symmetry for the opposite pairs of sides.
In this case, we don't have a square (we can prove this by finding the lengths of each side of the parallelogram), so we move on.
--------------
If the parallelogram is a rectangle, then we'll have two lines of symmetry: one for each pair of opposite sides.
However, we don't have a rectangle either. We can prove this by finding the slopes of the blue lines of the parallelogram, and finding they are not perpendicular slopes.
So we move on.
---------------
The last case is a parallelogram that isn't a rectangle. So it's not a square either. That's what we have here. For parallelograms of this nature, there are no lines of symmetry. We cannot fold it along any line to have it match up with itself.
So that's why the answer is "no" to both of these questions.

No and No.

Answers
Answer:
Butthead has $2.3345564757548586e+217 more money than Little Jimmy. Step-by-step explanation:
Since we need to find the difference, subtract the larger number by the smaller number. In this case, Butthead’s money minus Little Jimmy’s money. The two SUPER BIG numbers can be converted to:
2.3345564757548586e + 217 − 3.8472920439976386e + 74
This equals: 2.3345564757548586e+217
So, Butthead has $2.3345564757548586e+217 more money than Little Jimmy.

Answers
Answer:
A (3, 1)Step-by-step explanation:
If we have the coordinate (x,y), if this coordinate is rotated by 180 degrees clockwise, the resulting coordinate will be expressed as (-x, -y) i.e the original coordinate axis are both negated.
Given the coordinate C(-3, -1), if this coordinate is rotated clockwise about the origin, the coordinate of the resulting point will be at C' (-(-3), -(-1))
C' (-(-3), -(-1))
C' = (3, 1)
Hence option A is correct

Answers
Answer:
15m-30
Step-by-step explanation:
To simplify this expression we simply need to multiply the equation out to get rid of the parenthesis.
So, 5 X 3m = 15 m and 5 X 6 = 30
So, our simplified expression is 15m-30
Hope this Helps!!! :)
Let me know in the comments if I should change anything or if the answer was perfect!
The simplest form of the expression is 15 (m - 2).
We have,
5 (3m - 6)
- Distributive property in the expression.
5 x 3m - 5 x 6
15m - 30
- Factoring out 15.
15 (m - 2)
Now,
It can not be further simplified.
Thus,
15 (m - 2) is the simplified form of the expression.

Answer:

Step-by-step explanation:
Closely pay attention to the transversal line running from up-left to down-right.
y) you will notice that the angle to the right of z is corresponding with 50 then 50 will be vertically opposite 6y + 2 hence making them equal.
6y - 2 = 50
6y = 50 - 2
6y = 48
y = 6
z) vertically opposite angles are equal hence the 50 will be equal to the empty space in the triangle.
z + 60 + 50 = 180
z + 110 = 180
z = 180 - 110
z = 70
2y + 3z
2(6) + 3(70)
12 + 210
= 222
