Answer:

Step-by-step explanation:

The slope-intercept form is

y=mx+b, where m is the slope and b is the y-intercept.y=mx+bRewrite in slope-intercept form.Simplify 2(x+1).Apply the distributive property.

y+5=2x+2⋅1

multiply 2 by 1.

y+5=2x+2

Move all terms not containing y to the right side of the equation.Subtract 5 from both sides of the equation.

y=2x+2−5

y=2x−3

the slope is the "m" so the slope is 2

A passenger traub keaves a depot 1.5 hours after a freight train leaves the same depot. The passenger train is travleing 18 mph

skelet666 [1.2K]

Answer:

Speed of passenger train=18+30=48 mph

Speed of freight train=30 mph

Step-by-step explanation:

Let x be the speed of freight train.

Speed of passenger train=x+18 mph

Time taken by freight train=1.5+2.5=4 hrs

Time taken by passenger train to overtake the freight train=2.5 hrs

Distance= $Speed\times time$

By using this formula

Distance traveled by passenger train=2.5(x+18) miles

Distance traveled freight train=4x

According to question

$2.5(x+18)=4x$

$2.5 x+45=4x$

$45=4x-2.5 x$

$45=1.5 x$

$x=\frac{45}{1.5}=30$

Speed of freight train=30 mph

Speed of passenger train=18+30=48 mph

A wild horse runs at a rate of 8 miles per hour for 6 hours. Let yy be the distance, in miles, the horse travels for a given amo

spin [16.1K]

Answer:

$0\leq x\leq 6$

$0\leq y\leq 48$

Step-by-step explanation:

we are given

speed =8 mph

time = 6 hours

so, we have

$x=6$

now, we can find distance

distance = (speed)*(time)

$distance=8\times 6 miles$

$distance=48 miles$

so, we have

$y=48 miles$

so, our range for x and y can be

$0\leq x\leq 6$

$0\leq y\leq 48$

1.2,3,7.5,18.75 which formula can used to describe the sequence?

n200080 [17]

Answer:

$a_n=1.2 \cdot 2.5^{n-1}$

Step-by-step explanation:

The first step is to realize that this is a geometric sequence, where each next term in the sequence is 2.5 times larger than the previous. You can confirm this by the fact that 3=1.2*2.5, 7.5=3*2.5, and 18.75=7.5*2.5. Now, you can write the formula, where n is where the number is in the sequence, and a is the number itself. Since 1.2 is the first term in the sequence and the rate of expansion is 2.5, the formula is:

$a_n=1.2 \cdot 2.5^{n-1}$

Hope this helps!
