Answer:

Step-by-step explanation:

so you set up an equation because the sides are equal

10+x=4x+1

then you solve

10=3x+1

9=3x

x=3

You walk 2 miles in 1/2 hour. At that rate, how long will it take you to walk 3 miles?

masya89 [10]

The answer is 45 mins,
Since
1/2 = 30mins

2 miles
15+15mins

3miles
15+15+15mins
= 45mins

Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. W

Answer: b. y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

time spent on history homework: 20 minutes

time spent on each math problem: 2 minutes

math problem : x

total time spent :y

So, we have to multiply each math problem (x) by the time spent on each math problem and add the 20 minutes spent on history homework.

The expression obtained is equal to the total time spent

Mathematically speaking:

y=2x+20

x can be any real number greater than or equal to 0, ( it would be 0 if there aren't any math problems)

and y is any real number greater than or equal to 20. ( 20 minutes is the minimum time spent if there aren't any math problems)

Answer:

1.) 20.2

Step-by-step explanation:

1.) You need to use the distance formula:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

Find the distance of A to B first:

$(-2,2)(3,2)\\\\\sqrt{(3+2)^2+(2-2)^2}\\\\\sqrt{(5)^2+(0)^2}\\\\\sqrt{25} =5$

B to C:

$(3,2)(-1,-5)\\\\\sqrt{(-1-3)^2+(-5-2)^2}\\\\\sqrt{(-4)^2+(-7)^2}\\\\\sqrt{16+49}\\\\\sqrt{65} =8.06=8.1$

C to A:

$(-1,-5)(-2,2)\\\\\sqrt{(-2+1)^2+(2+5)^2}\\\\\sqrt{(-1)^2+(7)^2}\\\\\sqrt{1+49}\\\\\sqrt{50}=7.07=7.1$

Add distances to find the perimeter:

$5+8.1+7.1=20.2$

2.) Part A:

You need to use the mid-point formula:

$midpoint=(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2} )$

$(3,2)(7,11)\\\\(\frac{3+7}{2},\frac{2+11}{2})\\\\(\frac{10}{2},\frac{13}{2})\\\\m=( 5,6.5)$

Part B:

1. Use the slope-intercept formula:

$y=mx+b$

M as the slope, b the y-intercept.

Find the slope of the two points A and B using the slope formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{rise}{run}$

Insert slope as m into equation.

Take point A as coordinates $(x,y)$ and insert into the equation. Solve for the intercept, b:

$(y)=m(x)+b$

Insert the value of b into the equation.

2. Use the mid-point coordinate. Take the slope.

If you need to find the perpendicular bisector, you will take the negative reciprocal of the slope. Switch the sign and flip it. Ex:

$\frac{1}{2} =-\frac{2}{1}=-2\\$

Insert the new slope into the slope-intercept equation as m.

Take the mid-point coordinate as (x,y) and insert into the equation with the new points. Solve for b.

Insert the value of b.

Answer:

my only guess is that if x and y have the same value for both equations it would not make sense if you have the same 2x+3y equal 2 different things

Step-by-step explanation:

thats my guess i hope this helps
