Q=  y=-2x+2.5

Step-by-step explanation:

the formula is y=mx+b

M=slope

B=y-intercept

The y-intercept is the number that your line goes through

The slope is two ordered pairs where you use the formula rise over run to find your slope.

Step-by-step explanation:

Answer:

389,936,267,767

Step-by-step explanation:

thats the one

Let, number of double rooms and single rooms are d and s.

d + s = 26     ....1 )

Hotel rents double rooms at $34 per day and single rooms at $27 per day.

34d + 27s = 807   ....2)

Solving equation 1 and 2, we get :

34( 26 - s ) + 27s = 807

884 - 34s + 27s = 807

7s = 77

s = 11

And d = 26 - 11 = 15

Therefore, number of double rooms and single rooms are 15 and 11.

Hence, this is the required solution.

Answer:

The length of the hypotenuse is [tex]2\sqrt{10}[/tex] ≅ 6.325

Step-by-step explanation:

∵ A right angle is formed by the x-axis, y-axis and the line y = -3x + 6

∴ The line intersected the x-axis at point (x, 0)

→ To find x substitute y in the equation by 0

∵ 0 = -3x + 6

→ Add 3x to both sides

∴ 0 + 3x = -3x + 3x + 6

∴ 3x = 6

→ Divide both sides by 3

∵ [tex]\frac{3x}{3}=\frac{6}{3}[/tex]

∴ x = 2

∴ The line intersected the x-axis at point (2, 0)

∵ The line intersected the y-axis at point (0, y)

→ Substitute x in the equation by 0 to find y

∴ y = -3(0) + 6

∵ y = 0 + 6

∴ y = 6

∴ The line intersected the xyaxis at point (0, 6)

∵ The endpoints of the hypotenuse are (2, 0) and (0, 6)

→ Use the rule of the distance d = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex] to find it

∵ x1 = 2 and y1 = 0

∵ x2 = 0 and y2 = 6

∴ h = [tex]\sqrt{(0-2)^{2}+(6-0)^{2}}=\sqrt{4+36}=\sqrt{40}=2\sqrt{10}[/tex]

∴ The length of the hypotenuse is [tex]2\sqrt{10}[/tex] ≅ 6.325

Step-by-step explanation:

Since we are not told what to find, we can as well find the time taken by the rocket to reach its maximum height as shown

The rocket reaches its maximum height when the velocity is zero

v = dh/dt

v = -32t+64

Since v = 0 at maximum height

0 = -32t+64

32t = 64

t = 64/32

t = 2secs

Hence the rocket reaches the maximum height after 2secs

Answer:

x=10

Step-by-step explanation:

Perimiter is 2(x+y) with x and y being the two differend sides. First side is 3x and the second is   2x+4. 2(3x+2x+4)=108. 10x+8=108 10x=100 x=10.

The sides are 24 and 30

Please mark brainliest hope this helps :D

Answer:

x=10

Step-by-step explanation:

Since this is a rectangle, we know that the values of opposite sides are equal and that the perimeter is all of the sides' values combined. Therefore:

2(2x+4)+2(3x)=108

First, we need to distribute the 2s on the left side.

4x+8+6x=108

Combine like terms.

10x+8=108

Subtract the 8 from both sides.

10x=100

Divide by 10.

x=10

Answer:

Ella

Step-by-step explanation

Ella travelled faster than Dominique by 50 miles/hr.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have Dominique and Ella are comparing whose jet traveled faster.

The speed of the jet will be equivalent to slope of the line representing the motions.

Dominique's speed = (2200 - 1100)/(4 - 2) = 1000/2 = 500 miles/hr

Ella's equation of motion -

y = 550x

Ella's speed = 550 miles/hr

Therefore, Ella travelled faster than Dominique by 50 miles/hr.

#SPJ5

Answer:

see explanation

Step-by-step explanation:

Calculate the distance between (x, y) and the 2 given points and equate them.

Using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (x, y) and (x₂, y₂ ) = P(- 3, 4)

d = [tex]\sqrt{(-3-x)^2+(4-y)^2}[/tex]

Repeat with (x₁, y₁ ) = (x, y) and (x₂, y₂ ) = Q(2, - 1)

d = [tex]\sqrt{(2-x)^2+(- 1- y)^2}[/tex]

Equating both distances

[tex]\sqrt{(2-x)^2+(-1-y)^2}[/tex] = [tex]\sqrt{(-3-x)^2+(4-y)^2}[/tex]

Square both sides

(2 - x)² + (- 1- y)² = (- 3 - x)² + (4 - y)² ← expand and simplify both sides

4 - 4x + x² + 1 + 2y + y² = 9 + 6x + x² + 16 - 8y + y²

subtract x² + y² from both sides

5 - 4x + 2y = 25 + 6x - 8y ( add 8y to both sides )

5 - 4x + 10y = 25 + 6x ( subtract 5 from both sides )

- 4x + 10y = 20 + 6x ( add 4x to both sides )

10y = 10x + 20 ( divide all terms by 10 )

y = x + 2 ← as required

Answer: 32.0%

Step-by-step explanation:

The price of car last month = $250

The price of the car this month = $330

Increase in price = $330 - $250 = $80

Percentage increase = (Increase in price/Cost price last month) × 100

= $80$250 × 100

= 0.32 × 100

= 32.0%

The percent of increase in the price of the car is 32.0%.

This can be determined by the concept of straight line. [tex]\bold{y=-2x+17}[/tex]  is the slope-intercept form of [tex]2x+y=17[/tex].

Given: 2x + y = 17  

As, we  know that,

Equation of line is,

 [tex]\bold{y=mx+c}[/tex]

Where, 'm ' gives the slope/gradient of the line and 'c' gives y-intercept.

From the given equation,

[tex]2x+y=17[/tex]  

Solve  it further , we get,

[tex]\bold{y=-2x+17}[/tex]

This is the slope-intercept form of [tex]2x+y=17[/tex].

Here, comparing this with [tex]y=mx+c[/tex], we get

m= -2 ( slope/gradient)  and c= 17  (y-intercept)

So, slope / gradient of line : m= -2.

Answer:

Solution:

Change the divisor 6.410251 to a whole number by moving the decimal point 6 places to the right. Then move the decimal point in the dividend the same, 6 places to the right.

We then have the equations:

2000000 ÷ 6410251 = 0.312

and therefore:

2 ÷ 6.410251.6109 1) = 0.312

Answer:

y=2x+4

Step-by-step explanation:

Answer:

The slope-intercept equation is y=2x+4

Step-by-step explanation:

The y-intercept is where it crosses the y-axis, so 4, and to find the slope find perfect points or pretty points and rise then run.  I took the point (0,4) and found the next pretty point (1,6) and rise/run it. In order to get to the next point  you have to rise 2 and run 1 or 2/1 which is 2, so the slope is 2, then you plug it into the equation y=mx+b the y=intercept is b and the slope is m.

Answer: y=-2^x is an equation.

I got the second one wrong.

The base of the exponential relationship that gives the graph that is below

the horizontal x-axis has a negative constant coefficient.

The table that matches the relationship is the option;

Reasons:

Points on the graph are; (0, -1) (1, -2), and (2, -4).

The above points can be presented in a tabular form as follows;

[tex]\begin{tabular}{|c|c|c}x&y\\0&-1\\1&-2\\2&-4\end{array}\right][/tex]

The above table which corresponds with the first table is the table that

matches the relationship of the graph.

By using the equation, y = -2ˣ, we have;

At x = 0, y = -(2⁰) = -1 which gives the point (0, -1)

At x = 1, y = -2¹ = -2, which gives (1, -2)

At x = 2, y = -2² = -4, which gives (2, -4)

The above points are the points on the graph, therefore, the equation is the option; y = -2ˣ
