Evaluate x + y when x = -19/12 and y = -7/5
Hey there!
x + y
= -19/12 + (-7/5)
= -19/12 - 7/5
= -95/60 + -84/60
= -95/60 - 84/60
= -95 + (-84) / 60 - 0
= -95 - 84 / 60
= -179 / 60
Therefore, the answer should be:
-179 / 60
Good luck on your assignment & enjoy your day!

Answer:
5. x = 17
7. x = 2
Step-by-step explanation:
The applicable relation is, "the product of the near distance to the circle and the far distance to the circle is the same for each secant." Distance is measured from the point where the secants intersect.
__
5.Using the rule, we have ...
7(7+x) = 8(8+13)
7+x = 24 . . . . . . . . . divide by 7
x = 17 . . . . . . . . . . subtract 7
__
7.The same rule applies.
7(7 +6x -1) = 9(9 +x +3)
42x +42 = 9x +108 . . . . . . simplify
33x = 66 . . . . . . . . . . . . . subtract 9x+42
x = 2 . . . . . . . . . . . . . . divide by 33

Situation:
You invest $100 in an account that pays
an interest rate of 6.5%, compounded
continuously.
Calculate the balance of your account after 6
years. Round your answer to the nearest
hundredth.
[tex]~~~~~~ \textit{Continuously Compounding Interest Earned Amount} \\\\ A=Pe^{rt}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$100\\ r=rate\to 6.5\%\to \frac{6.5}{100}\dotfill &0.065\\ t=years\dotfill &6 \end{cases} \\\\\\ A=100e^{0.065\cdot 6}\implies A=100e^{0.39}\implies A\approx 147.70[/tex]
The balance of your account after 6 years with continuous compounding would be approximately $147.56.
To calculate the balance of your account after 6 years with continuous compounding, you can use the formula:
[tex]\[ A = P \times e^{rt} \][/tex]
where:
[tex]\( A \) =[/tex] the balance after [tex]\( t \)[/tex] years
[tex]\( P \) =[/tex]the principal amount (initial investment) = $100
[tex]\( r \) =[/tex] the annual interest rate (in decimal form) = 6.5% = 0.065
[tex]\( t \) =[/tex] the number of years = 6
[tex]\( e \) =[/tex] Euler's number (approximately 2.71828)
Let's plug in the values and calculate the balance:
[tex]\[ A = 100 \times e^{0.065 \times 6} \]\[ A = 100 \times e^{0.39} \]\[ A = 100 \times 1.47560080488 \]\[ A = 147.560080488 \][/tex]
Rounding the answer to the nearest hundredth:
[tex]\[ A \approx $147.56 \][/tex]

A school needs to buy new notebook and desktop computers for its computer lab. The notebook computers cost $275 each, and the desktop computers cost $175 each. How much would it cost to buy 10 notebooks and 16 desktop computers? How much would it cost to buy nn notebooks and dd desktop computers?
Write the equation for total cost, nn notebooks and dd desktop computers:
The cost to buy 10 notebooks and 16 desktop computers is $5550
Cost of notebook computers = $275
Cost of desktop computers = $175 each
The cost to buy 10 notebooks and 16 desktop computers will be:
= 275(10) + 175(16)
= 2750 + 2800
= $5550
The cost to buy n notebooks and d desktop computers will be:
= 275(n) + 175(d)
= 275n + 175d

Using it's concept, it is found that the mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
What is the mean absolute deviation of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.The mean absolute deviation represents the average by which the values differ from the mean.In this problem, the mean is given by:
M = (65 + 58 + 64 + 61 + 67)/5 = 63.
Hence the mean absolute deviation is given by:
MAD = (|65-63| + |58-63| + |64-63| + |61-63| + |67-63|)/5 = 14/5 = 2.8.

write the equation of the line that passes through (-7,-4) and (-6,-2) in slope intercept form
Answer:
y = 2x + 10
Step-by-step explanation:
Hi there!
We are given the points (-7, -4) and (-6, -2) and we want to write the equation of the line that passes through these points in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
First, we need to find the slope (m) of the line
The slope can be calculated from 2 points using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything we need to find the slope, but let's label the values of the points to avoid any confusion & and mistakes
[tex]x_1= -7\\y_1=-4\\x_2=-6\\y_2=-2[/tex]
Substitute these values into the formula (note: remember that the formula has subtraction in it!)
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-2--4}{-6--7}[/tex]
Simplify
m=[tex]\frac{-2+4}{-6+7}[/tex]
Add the numbers
m=[tex]\frac{2}{1}[/tex]
Divide
m=2
The slope of the line is 2
We can substitute that in:
y = 2x + b
Now we need to find b
As the equation passes through both (-7,-4) and (-6,-2), we can use either point to help solve for b
Taking (-6, -2) for example:
Substitute -6 as x and -2 as y into the equation.
-2 = 2(-6) + b
Multiply
-2 = -12 + b
Add 12 to both sides
-2 = -12 + b
+12 +12
___________
10 = b
Substitute 10 as b.
y = 2x + 10
