Answer 1

Answer:

y = x

Step-by-step explanation:

Hi,

We know that in the equation...

y = mx + b

m = slope

So, to find the equation of the line, we have to plug in what we already know. So...

-7 = 1 (-7) + b

Solve...

-7 = -7 + b

b = 0

That means that your equation is...

y = x

(you don't have to put the one in front of the x)

I hope this helps :)

Answer 2
y = mx + b
The m represents your slope.
y = (1)x + b
You can now plug in your coordinate points.
-7 = -7 + b
You will notice that they are equal to each other, which means b can only equal zero.
The equation will be...
y = x + 0
or
y = x

Update: answer is 0,5

Answers

Answer:

x = 0 , 5

Step-by-step explanation:

[tex]\frac{2x}{x-3}=\frac{3x}{x-2}[/tex]

Cross multiply,

2x* ( x - 2) = 3x *(x - 3)

2x*x - 2*2x  = x*3x - 3*3x

2x² - 4x   = 3x² - 9x

subtract 2x² from both sides

-4x = 3x² - 2x² - 9x           {Combine like terms}

-4x = x² - 9x

Add 9x to both sides

-4x+ 9x = x²

x² = 5x

x² - 5x = 0

x(x - 5) = 0

x = 0  ; x - 5 = 0

                 x = 5

y = [? ]ft

Answers

Answer:

178.3

Step-by-step explanation:

Hello There!

We can find the value of y using trigonometry

These are the trigonometric ratios

Remember SOHCAHTOA

Sine = Opposite over Hypotenuse

Cosine = Adjacent over Hypotenuse

Tangent = Opposite over Adjacent

For the angle that has a measure of 27 degrees

we are given its adjacent angle and we need to find its opposite angle (y)

Adjacent and Opposite sides corresponds with the trigonometric ratio Tangent so we are going to use the trigonometric ratio tan to solve for y

Now we set up an equation (remember tangent = opposite over adjacent)

[tex]tan(27)=\frac{y}{350}[/tex]

Now that we have created an equation we want to solve for y

What we want to do is isolate the variable using inverse operations

So basically we want to get rid of the 350

The opposite of division is multiplication so we multiply each side by 350 to get rid of it

[tex]tan(27)*350=350tan(27)\\\frac{y}{350} *350=y\\y=350tan(27)\\350tan(27)=178.3339073\\[/tex]

so we can conclude that y = 178.3339073

finally we want to round to the nearest tenth and we get that the answer is 178.3

A car travels 30
303
miles in
of an hour. What is the average speed, in miles per hour,
of the car?

Answers

Answer:

45.3 miles/h

Step-by-step explanation:

let 'x' be the speed of the car.

60 × 2/3 = 120/3 = 40

30 × 1/5 = 151/5

151/5 /40 = x / 60

151 / 200 = x / 60

=> x = (151×60) / 200

=> x = 45.3

A boat can travel 40mph in still water. If it travels 126 miles with the current in the same length of time it travels 114 miles against the current, what is the speed of the current?
no links please

Answers

Answer:

rate of the current = 2 mph

Step-by-step explanation:

d = rt

Let c = rate of the current

Rate going downstream = c + 40

Time going downstream = 126/(40 + c)

Rate going up stream =  40 - c

Time going upstream = 114/(40 - c)

Since the times are equal, then

126/(40 + c) = 114/(40 - c)

126(40 - c) = 114(40 + c)

5040 - 126c = 4560 + 114c

   240c  =  480

          c = 2 mph
