Solve the inequality and graph your answerx + 19 < 16
Answers
Solution
For this case we have this inequality:
x+19 <16
We can subtract 16 in both sides and we got:
x +19-19 < 16-19
x < -3
For the second part we have:
[tex]\frac{x}{5}\ge-2[/tex]We can multiply both sides by 5 and we got.

Answers
Given
Sasha has $850 to deposit into two accounts.
Sasha will deposit $450 at First Oak Bank.
She will deposit the rest into River Point Bank.
Sasha will not make additional deposits or withdrawals.
To find how much more money will be in her account at First Oak than at River Point after 2 years.
Now,
It is given that,
In the first Oak bank the rate of interest is 6%.
Then, the amount in her account after 2 years is,
[tex]\begin{gathered} A=P+\frac{Pnr}{100} \\ A=450+\frac{450\times2\times6}{100} \\ A=450+54 \\ A=454 \end{gathered}[/tex]Hence, the amount in the First Oak bank is $454.
In the River point bank the rate of interest is 2% compounded annually.
Then, the amount in her account after 2 years is,
[tex]\begin{gathered} A=P(1+\frac{r}{100})^t \\ A=P(1+\frac{2}{100})^2 \end{gathered}[/tex]Since Sasha will deposit $450 at First Oak Bank and she will deposit the rest into River Point Bank.
Then, the amount deosited in the River point bank is,
[tex]\begin{gathered} P=850-450 \\ =400 \end{gathered}[/tex]Therefore,

This parabola opens to the left. P. O A. True O B. False
Answers
Answer:
True.
Explanation:
We take the analogy from the graph of y = ax^2
When y = x^2, the parabola opens upward (towards the positive y-axis). However, when the parabola is y = -x^2, it opens downward (towards the negative y-axis).
In a similar way, when we have x = ay^2, the parabola opens towards the positive x-axis ( towards the right). However, if we have x = -ay^2, then the parabola opens towards the negative x-axis ( towards the left).
Therefore, by comparison, x = - 1/8 y^2, opens to the left, and the correct option to choose is 'True'.

Answers
The given percentage is 1.75%.
To find the decimal expression of this percentage, we just have to divide it by 100. It's important to know that when we divide a number by 100, we just have to move the decimal point two spots to the left, as follows
[tex]\frac{1.75}{100}=0.0175[/tex]Therefore, as a decimal is 0.0175.
Now, to find the simplified fraction, we divide the number by 10000, as follows
[tex]\frac{175}{10000}[/tex]The reason for dividing by 10000 is that we need to have a whole number in the numerator, so the extra two zeros allow us to get rid of the two of the number. Now, we simplify the fraction dividing each part by 5
[tex]\frac{175\colon5}{10000\colon5}=\frac{35}{2000}=\frac{7}{400}[/tex]Once we get the simplest fraction, we can finish.
Therefore, as a simplified fraction is 7/400.
