What is the equation helppp
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.

Dominique and Ella are comparing whose jet traveled faster. The graph shows the relationship between the total distance Dominique traveled and the time in hours. The distance Ella traveled after x hours can be represented by the equation y=550x.
Who if anyone, traveled at a faster speed? Explain.
Answer:
Ella
Step-by-step explanation
Ella travelled faster than Dominique by 50 miles/hr.
What is the general equation of a Straight line?
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.

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.

A motel rents double rooms at $34 per day and single rooms at $27 per day. If 26 rooms were rented one day for a total of $807, how many rooms of each kind were rented? system of equations
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.
Last month, the online price of a powered ride-on car was $250. This month, the online price is $330. What is the percent of increase in the price of the car? Round the percent to the neartst tenth if necessary.
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%.

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

a right angle is formed by the x-axis, and the line y = -3x + 6. what is the length of the hypotenuse?
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:
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

the graph below models an exponential relationship. drag one equation and one table to match the relationship shown.
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 equation that matches the given relationship is the option; y = -2ˣThe table that matches the relationship is the option;
[tex]\begin{tabular}{|c|c|c}x&y\\0&-1\\1&-2\\2&-4\end{array}\right][/tex]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

. A rocket carrying fireworks is launched from a hill above a lake. The rocket will fall into lake after exploding at its maximum height. The rocket's height above the surface of the lake is given by h(t) = −16t 2 + 64t + 80, where h is in feet and t is in seconds
Answer:
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
