Answer:

  (a)  8 km

Step-by-step explanation:

Let m represent the distance (in kilometers) Michelle has walked. Then Janet walked a distance of (m-2). These distances are at right angles, so the distance between them can be found using the Pythagorean theorem.

  m² +(m -2)² = 10²

  m² +m² -4m +4 = 100

  2m² -4m = 96 . . . . . . subtract 4, collect terms

  m² -2m +1 = 49 . . . . . divide by 2 and add 1

  (m -1)² = 7² . . . . . . .write as squares

  m -1 = 7 . . . . . . positive square root

  m = 8

Michelle walked 8 km.

Leya [2.2K]

Answer:

The solution is the point (-2,1)

Step-by-step explanation:

we have

-2x+3y=7 ----> equation A

5x+8y=-2 ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system is the intersection point both lines

using a graphing tool

The solution is the point (-2,1)

Slope-intercept inequality for the graph, I have no idea how to do this
nignag [31]
Slope intercept inequality is in the form mx+b m standing for slope and b standing for y intercept
m= 4/3
b= -2 line passes (0,-2)

use y2-y1/x2-x1
(3,2)(-3,-6)
-6-2/-3-3
-8/-6
4/3 = slope
Let's set it up
y_ 4/3x-2
now the shaded area is on the LEFT side so this means that THE X has to be less than
The line is dashed which means it is not equal to!!
y >4/3x-2
plug in any (x,y) from the shaded area and see if this inequality is true
(-1,1)
1 >4/3 (-1)-2
1 >-4/3-2
1 >-4/3-6/3
1 >-10/3

-1/5c+2+c=1/5(10c-20)
Andreyy89

Let's solve your equation step-by-step.

(− 1 /5 )(c)+2+c= 1 /5  (10c−20)

Step 1: Simplify both sides of the equation.

(− 1 /5 )(c)+2+c= 1 /5 (10c−20)

(− 1 /5 )(c)+2+c=( 1 /5 )(10c)+( 1 /5 )(−20) (Distribute)

−1 /5 c+2+c=2c+−4

( −1 /5 c+c)+(2)=2c−4 (Combine Like Terms)

4 /5 c+2=2c−4

4 /5 c+2=2c−4

Step 2: Subtract 2c from both sides.

4/5 c+2−2c=2c−4−2c

−6 /5 c+2=−4

Step 3: Subtract 2 from both sides.

−6 /5 c+2−2=−4−2

−6 /5 c=−6

Step 4: Multiply both sides by 5/(-6).

( 5 /−6 )*( −6 /5 c)=( 5 /−6 )*(−6)

c=5

Answer:

c=5
