X = 7 + 2y
x - y = 22

7 + 2y - y = 22
y = 15

x = 7 + 2(15)
x = 7 + 30
x = 37

Answer:

The value of the larger number is 37 .

Step-by-step explanation:

Let us assume that the first number be u.

Let us assume that the second number be v.

As given

One number is 7 more than twice another.

Than the equation becomes

u = 7 + 2v

As given

If their difference is 22 .

Than the equation becomes

u - v  = 22

Than two equations are

u = 7 + 2v and u - v  = 22

Put u = 7 + 2v in equation u - v  = 22 .

7 + 2v - v = 22

7 + v = 22

v = 22 - 7

v = 15

Put the value of v in the equation u = 7 + 2v .

u = 7 + 2 × 15

u = 7 + 30

u = 37

Therefore the value of the larger number is 37 .

Graph f(x)=3x+5 and g(x)=3x-2
IgorLugansk [536]

Answer:

Two parallel lines

Step-by-step explanation:

the slopes are the same: slope = 3

f(x) 3x + 5                          g(x) = 3x - 2

Pick at least three x values and find their corresponding values for y. Remember the f(x)  and g(x) represent y

                                   f(x) = 3x + 5                           g(x) = 3x - 2

                                    y = 3x + 5                              y = 3x - 2

let x = 0                       y = 3(0) + 5                              y = 3(0) - 2

                                     y = 5                                         y   =  -2

Ordered pair                (0, 5)                                        (0, -2)

Let x = 1                      y = 3(1) +5                                y  = 3(1) - 2

                                  y = 8                                         y = 1

ordered pair                (1, 8)                                        (1, 1)

Let x = -1                  y = 3(-1) + 5                               y = 3(-1) - 2                  

                                  y = 2                                        y =  -5

ordered pair             (-1, 2)                                         ( -1, -5)

Locate the ordered pairs and draw the graph on the lines.  

you will graph two parallel lines

Two planes are 1380 miles apart and traveling toward each other. One plane is traveling
vaieri [72.5K]

Answer: plane 1: 420 mph; plane 2: 500 mph

Step-by-step explanation:

This is a physics exercise, but in order to solve this problem, you need to identify both planes first:

Let's call the plane 1 speed X

V1 = X

And V2 would be:

V2 = V1 + 80 = X + 80

If we combine both speeds:

V = V1 + V2 = X + X + 80 = 2X + 80

Now that we have an expression for the combined speed, let's see the rest of the data:

Distance: d = 1380 mile

Time: t = 1.5 h

We also know that the formula to get speed is:

V = d/t

We have the combined speed, so, let replace it in the above formula to solve for X:

2X + 80 = 1380/1.5

2X + 80 = 920

2X = 920 - 80

2X = 840

X = 840/2

X = V1 = 420 mph

We have V1, so to get V2:

V2 = 420 + 80 = 500 mph
