Solve each equation for the given variable -2x+5y=12 for y
'

Answers

Answer 1
Answer: so basically get 1 of y on one side so
-2x+5y=12
add 2x to both sides
5y=12+2x
divide both sides by 5
y=(12+2x)/5

The map below shows the length of a proposed land bridge at Phil Hardberger Park. The length of the land bridge is represented by PHin the map below.
P(2,55)
H(32, 15)
On the map, each unit represents 1 yard. To the nearest yard, what is the actual length of the land bridge from P to H?
A 50 yards
B. 150 yards
C. 78 yards
D. 234 yards

Answers

Answer:

A; the actual length of the land bridge from P to H is 50 yards

Step-by-step explanation:

Here in this case, given the coordinates of P and H, we want to calculate the actual length of the distance between the two points.

Mathematically, to calculate this distance, we make use of the distance formula;

D = √(x2-x1)^2 + (y2-y1)^2

In this case, (x1,y1) = (2,55) while (x2,y2) = (32,15)

Substituting these values

D = √(32-2)^2 + (15-55)^2

D = √(-30)^2 + (-40)^2

D = √(900 + 1600)

D = √(2,500)

D = 50 units

Now, we know that each units represent 1 yard, thus 50 units will represent 50 * 1 = 50 yards

Let y be a function of x such that 2x-3y=6. What is the rate if change of y with respect to x?

Answers

2x - 3y = 6
first, isolate y:
-3y = -2x + 6
y = (2/3)x - 2
This is a linear function in standard form, so we know that the slope (in this case the rate of change of y in respect to x) is 2/3

The sum of three consecutive numbers is 84. what is the largest of these numbers? 26 27 28 29

Answers

Answer:

The largest number is 29.

Step-by-step explanation:

Let the numbers be = x , x+1 , x+2

As given, their sum is 84, we can write as:

x+x+1+x+2=84

=> 3x+3=84

=> 3x=84-3

=> 3x=81

x = 27

So, x+1= 27+1=28

And x+2 = 27+2=29

Hence, the largest number is 29.
The largest of the three consecutive numbers whose sum equals to 84 is 29.
