Answer:

x=1

y=-1

Step-by-step explanation:

x = y+2

x+2y = 5

y+2 +2y = 5

3y +2 = 5

3y = 3

y=1

x=-1

Answer:

Step-by-step explanation:

Insert y+2 into your x so...

y+2+2y=5

Then solve...

Combine like terms so 2y+y is 2y^2 (squared)

and..

5-2 is 3

you are left with 2y^2 (squared) = 3 is 0.75

Does anyone know how to do this (#2) PLZZZZ HELPPPPPPPP
timurjin [86]

Answer:

a.- slope= 36

Interpretation : The cable car travels 36 meter per minute

b.- y = 36x + 100

c.- 640 meters

Step-by-step explanation:

a.-

Find slope using the slope formula : \frac{y2-y1}{x2-x1}

Plug in the two given points: \frac{1000-100}{25-0}

Subtract the numbers : \frac{900}{25}

Reduce the fraction : 36

b.-

Using the given y-interspet (100) and the slope create an equation: y = 36x + 100

c.-

Using the equation you created plug in 15 for x to find the

distance: y = 36 (15) + 100

Multiply the numbers : y = 540 + 100

Add the numbers : y = 640

Please help I need answers #5 and #6 more, but if you could do all that would be great thanks it’s urgent!!!
Rudiy27

Answer:

Step-by-step explanation:

Answer for #5

Two Points M(-7,1) and N(5,1).

1. Formula is Distance = \sqrt{(x2-x1)^2 - (y2-y1)^2}

2. Let’s say (x1,y1) = (-7,1) and (x2,y2) =(5,1)

3. Distance = \sqrt{(5-(-7))^2 + (1-1)^2} = \sqrt{(5+7)^2-(0)^2} = \sqrt{(12)^2+0} =\sqrt{144} = 12}

so distance between two warehouses is 12 miles

Answer #6

In the question it is saying the “Distance between two stores is half the distance between warehouses“ so it is   \frac{12}{2} = 6 miles

Answer #7

S1(-4,1) and distance of S1 and M is 3 Miles.

Answer #8

S2(2,1) and distance of S2 and M is 3 miles.
