Using a system of equations, it is found that the value of “b” in ax^2 + bx + c would be of:

B. 6

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, when x = 0, y = 15, hence c = 15.

When x = -1, y = 10, hence:

a - b + 15 = 10

a - b = -5

a = b - 5.

Then, when x = 1, y = 22, hence:

a + b + 15 = 22

a + b = 7

b - 5 + b = 7

2b = 12

b = 6.

Hence option b is correct.

50/8 converted as a mixed number

AleksandrR [38]

50/8

Simply divide 8 into 50. That is 6. Because 8 *6 = 48.

There would be a remainder of 2.

So 50/8 = 6 whole number 2/8.

So the answer = 6 whole number 2/8. As mixed fraction.

You can reduce the 2/8 to 1/4.

So 6 whole number 1/4 is also correct.

Write a variable expression to describe the rule for the sequence. Then find the 100th term. 35, 36, 37,...

Dmitry [639]

Given expression is 35, 36, 37, 38...

First term a = 35

Common difference d = 36-35 = 1

Nth term of arithmetic sequence is:

$n_{th} = a+ (n-1)d$

$n_{th}= 35+(n-1)(1)$

$n_{th} = 34+n$

To find the 100th term, substitute n = 100

$n_{100} = 34 +100$

$n_{100} =134$

Correct option is B

What is the future value of 300000 with an interest rate of 17% per annum for 30 days?

Anvisha [2.4K]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$300000\\
r=rate\to 17\%\to \frac{17}{100}\to &0.17\\
t=years\to \frac{30}{365}\to &\frac{6}{73}
\end{cases}
\\\\\\
A=300000\left(1+0.17\cdot \frac{6}{73}\right)$

A. y=1/2x-2 <br> b. y=-1/2x+3<br> c. y=2x+1<br> d. y= -2x+4

Lyrx [107]

d. y=-2x+4

this is because in the formula used y=mx+b, b is represented as the the "y" intersept, which is 4. the slope, which is -2, is represented as x in this formula. therefore, D. y=-2x+4 is the correct answer
