Answer:

the standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. The standard form of a line is just another way of writing the equation of a line.

25 POINTS PLZ HELP ASAP!!!<br><br> Match the functions with their inverse functions.
antoniya [11.8K]
To calculate the inverse isolate x on one side and switch x with y on both sides

1)
y=(2x-3)/5
5y=2x-3
5y+3=2x
(5y+3)/2=x
-> f(x)=(5x+3)/2

2)
y=(x+8)/2
2y=x+8
2y-8=x
-> f(x)=2x-8

3)
y=(x+2)/7
7y=x+2
7y-2=x
-> f(x)=7x-2

4)
y=(1-2x)/x
y=(1/x)-2
y+2=1/x
x=1/(y+2)
-> f(x)=1/(x+2)

The distance between points (X7, Yı) and (4, 8) is the square root of (x7 - 8)2 +
serious [3.7K]

Answer:

B. False

Step-by-step explanation:

Given

Points: (x_7 - y_i),(4,8)

Required

Is the distance between them \sqrt{(x_7 - 8)^2 + (y_1 - 4)^2}

Given that there are two points, the distance between them is calculated using

Distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

In this case;

(x_1,y_1)= (x_7 - y_i)\\(x_2,y_2) =(4,8)

Substitute these in the given formula

Distance = \sqrt{(4- x_7)^2 + (8 - y_1)^2}

Comparing this with the given formula, both are not the same;

Hence, the formula is false and the correct formula is of the form \sqrt{(4- x_7)^2 + (8 - y_1)^2}

AveGali [126]
r\approx0.139

1) Since this is a Continuously Compounded operation in a 10 yrs period, then we can write out the following equation:

\begin{gathered} A=Pe^{rt} \\  \end{gathered}

2) Plugging into the equation the given data and since Otto is 20 yrs old and he plans to get $4,000 in ten years, we can write out:

\begin{gathered} 4000=1000e^{\mleft\{10r\mright\}} \\ \frac{4000}{1000}=\frac{1000e^{10r}}{1000} \\ 4=e^{10r} \\ \ln (4)=\ln (e)^{10r} \\ 10r=\ln (4) \\ r=\frac{\ln (4)}{10} \\ r=0.1386 \end{gathered}

3) Thus the rate Otto needs is

r=0.1386\approx0.139

Note that since the 0.1386 the six here is greater than 5 then we can round up to the next thousandth, in this case: 0.139. For the 0.1386 is closer to 0.139 (0.004) than to 0.138 (0.006).

Or 13.9%

castortr0y [4]

Answer:

distance=rate*time

2520=(r)(3)+(r+90)(3)    (they both travel for 3 hours)

2520=3r+3r+270

2520-270=6r

2250=6r

r=2250/6

r=375 mph

r+90=375+90=465 mph
