How can you determine the equation of a line in y =mx + b form from its graph?
Answers
Answer:
I'm gonna go a little out of order.
To determine b, find where the line crosses the y-axis. If it's positive, put it as " + " and if it's negative, put it as " - ".
To determine m, find two points on the line that are directly on the number. Example, choose (4, 1) instead of (4.1, 5.2). Go up/down and left/right (while making sure to count) until you reach the second number. going up and right will be considered positive while down and left are considered negative.
Using rise/run, put your number for up/down as a numerator over your left/right, which will be a denominator.
Insert m and b and you're good to go!
The perimeter of a triangle is 34 feet. One side of the triangle is 2 times the second side. The third side is 2 feet longer than the second side. Find the length of each side
Answers
Answer:
6.4 feet
12.8 feet
14.8 feet
Step-by-step explanation:
let x = length of 1st side
let 2x = length of 2nd side
let 2x + 2 = length of 3rd side
add them all together and set sum equal to 34
x + 2x + 2x + 2 = 34
5x + 2 = 34
5x = 32
x = 6.4, which is 1st side
2x = 12.8, which is 2nd side
2x + 2 = 14.8, which is 3rd side

Answer:
n= 0.121978
Step-by-step explanation:
1.6-4.7n+0.23=-4.4n+2.94
4.7n+1.83=-4.4n+2.94
4.7n=-4.4n+2.94-1.83
4.7n=-4.4n+1.11
4.7n+4.4n=1.11
9.1×n=1.11
n=1.11/9.1
n=0.121978
Answer:
n=-3.7
Step-by-step explanation:
1.6-4.7n+0.23=-4.4n+2.94
-4.7n+1.83=-4.4n+2.94
+4.4n both sides
-0.3n+1.83=2.94
-1.83 both sides
-0.3n=1.11

Assuming you require to simplify the expression.
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying the radicals
[tex]\sqrt{72}[/tex] = [tex]\sqrt{36(2)}[/tex] = [tex]\sqrt{36}[/tex] × [tex]\sqrt{2}[/tex] = 6[tex]\sqrt{2}[/tex]
[tex]\sqrt{242}[/tex] = [tex]\sqrt{121(2)}[/tex] = [tex]\sqrt{121}[/tex] × [tex]\sqrt{2}[/tex] = 11[tex]\sqrt{2}[/tex]
Then
2[tex]\sqrt{72}[/tex] + 5[tex]\sqrt{242}[/tex]
= 2(6[tex]\sqrt{2}[/tex] ) + 5(11[tex]\sqrt{2}[/tex] )

The energy that generates wind comes from what source A. Soar radiation B. Magnetic attraction C. Moon's gravity D. Coriolis effect
Answers
Answer:
A. Soar radiation
Step-by-step explanation:
Blowing wind rotates the wind turbine and generates the energy called wind energy. More the speed of wind, more the energy can be generated.
That's how, wind energy depends on the speed of the wind and the speed of the wind is due to the pressure difference in various regions.
The zone having more solar radiation has low pressure and the zone having less solar radiation have high pressure of air and winds flows from high to low-pressure zone.
Therefore, the energy that generates wind comes from what source soar radiation.
Hence, option (A) is correct.

Step-by-step explanation:
d is proportional to S^2
d=900 when s=20
calculate the value of D when S=25
Answers
Answer:
d = 1406.25
Step-by-step explanation:
Given d is proportional to s² then the equation relating them is
d = ks² ← k is the constant of proportion
To find k use the condition d = 900 when s = 20
900 = k × 20² = 400k ( divide both sides by 400 )
2.25 = k
d = 2.25s² ← equation of proportion
When s = 25, then
d = 2.25 × 25² = 2.25 × 625 = 1406.25

The Lopez family is traveling from the beach to their house at a average speed of 65 miles per hour. At noon, they have driven 50 miles. Which equation represents the total distance they have driven, d, in terms of the number of hours since noon, h?
Answers
The equation that represents the total distance they have driven, d, in terms of the number of hours since noon, h is:
d = 65h + 50
Which equation represents the total distance that the family has traveled?The equation that represents the total distance that the family traveled must show the initial distance they started with, the velocity at which they are traveling and the time they have covered.
The initial distance that they started with is = 50 miles
The velocity at which they are traveling is 65miles/hr
Therefore the total distance they have driven, d, in terms of the number of hours since noon, h
= 65h + 50
Therefore, the third option is correct.

Explain how the net of rectangular prism can help you find the surface area or the prism?
Answers
A 3d cardboard box has 6 sides, each of which are rectangles. If you unfold the 3D box, and flatten it out, then you'll be left with 6 rectangles such as what you see in the attachment below. This is one way to unfold the box. This flattened drawing is the net of the 3D rectangular prism. You can think of it as wrapping paper that covers the exterior of the box. There are no gaps or overlapping portions. If you can find the area of each piece of the net, and add up those pieces, that gets you the total area of the net. This is the exactly the surface area of the box.
In the drawing below, I've marked the sides as: top, bottom, left, right, front, back. This way you can see how the 3D box unfolds and how the sides correspond to one another. Other net configurations are possible.

How do i get the answer x= 3, -1 for equation (3/x^2)+ 2/x =1
Answers
Answer:
Steps below
Step-by-step explanation:
(3/x²)+ 2/x =1 (x ≠ 0)
(3/x²) + 2x/x² = 1
(3 + 2x) / x² = 1
3 + 2x = x²
x² - 2x - 3 = 0
(x + 1) (x - 3) =0
x = -1 or x = 3
Explain why it makes sense that a system of two lines with equal slopes but different y-intercepts has no solutions.
Answers
Answer:
Please check explanations
Step-by-step explanation:
Here, we want to seek why the system has no solutions
An example is necessary
Let us have two lines with equal slopes and different y-intercepts
y = 2x + 5
y = 2x - 3
To solve this system, we equate the y-values
2x + 5 = 2x - 3
The reason why this has no solution is that there is no x value that would validate the equality
It is impossible to find an x value which when inserted would make both equations equal
In the absence of this, we can make that conclusion that the system of equations has no solution

Answers
Answer:
76
Step-by-step explanation: Given that: There are 5 butterflies onscreen
The number of butterflies doubles every minute.
That is every increase in minute = double in the numbers of butterflies
Expressing in the power of 2
= 5×2^n. .......... 1
Where n is 4 which can as well range from ( 1,2,3,4 )
Hence, using the expression in equation 1
Ist minute where n = 1
5(2^1) = 10 butterflies
2nd minutes: where n = 2
5(2)(2) = 5(2^2) butterflies
After 3rd minutes :
5(2^3) butterflies where n = 3
After 4th minutes : where n = 4
5(2^4) butterflies
But at that point she was able to capture 4.
After 4 min, number on screen = 5(2^4) - 4
= 5(16) - 4
= 80-4
= 76
