Answer:
y = 6x-13
Step-by-step explanation:
Given: y+1=6(x-2)
Distribute 6: y +1 = 6x -12
Isolate y: y = 6x -13 (subtracted 1 from both sides)
This is now in the form y = mx +b

Answer:
It's not proportional
Step-by-step explanation:
The first 2 days are proportional because, they travel at an increment of 60 miles an hour.
But, on the third day, it is not proportional because they travel at an increment of 90 miles an hour.
360 / 4 = 90
120 / 2 = 60
60 / 1 = 60
Answer:
The answer would be yes and no!! But, it would be no!
Step-by-step Explanation:
Yes: On Monday and Tuesday, those would be proportional because they are just counting by 60´s. 60 plus 60 would give you 120.
No: On Wednesday, this ¨person¨ traveled 360 miles in 3 hours. Now, you aren´t counting by 60´s anymore. Even though you started out counting by the 60´s, doesn´t mean you will finish like that.
60´s:
1 hour = 60 mi
2 hours = 120 mi
3 hours should be = 180 miles, not 360 Because:
360 mi would be equal to 6 hours. Do you see where I´m going with this?
Hope that helps you so you can put it in a mathematical way. Have a great day!!

What is the x intercept of this quadratic/parabola?
Answer:
-3, 1
Step-by-step explanation:
There are actually 2 x-intercepts of the parabola. You can find them simply by looking along the x-axis and seeing where the lines of the parabola touch the axis, so -3 and 1.
Hope this helps :)
Answer:
1 and -3
Step-by-step explanation:
At x-intercept y = 0
So, parabola intersect x-axis at two places (1 , 0) and (-3 , 0)
X-intercepts are 1 and -3
A line passes through the points (-6, -8) and (-3,-7).
What is the equation of the line in Slope-Intercept Form?
A)y=1/3x-6
B) y=3x-6
C)y=1/3x+6
D) y=3x+6
Step-by-step explanation:
For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:
The question gives us two points, (-6, -8) and (-3,-7), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (-8 - (-7)) ÷ (-6 - (-3))
= -1 ÷ (-3)
= ¹/₃
Finding the Equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - (-7) = ¹/₃ (x - (-3))
we could also transform this into the slope-intercept form ( y = mx + c)
since y + 7 = ¹/₃ (x + 3)
⇒ y + 7 = ¹/₃ x + 1
∴ y = ¹/₃ x - 6

The latest thrill ride at a popular theme park takes roller coaster fans on an exciting ride. In the first 20 seconds, it carries its passengers up a 100-meter hill, plunges them down 72 meters, and quickly takes them back up a 48-meter rise. How much higher or lower from the start of the ride are they after these 20 seconds?

One grain of this sand approximately weighs 7 x 10^-5 g. How many grains of sand are there in 6300 kg of sand ? Give your answer in standard form
Answer:
90 000 000 000 Grains
Step-by-step explanation:
one grain equal approximately 0.00007 grams.
convert 6300 kg into grams (multiply by 1000) and that equals 6 300 000g.
divide that by the weight of a single grain and you get the number of grains in that weight. So 6300000/0.00007=90 000 000 000 grains.
The number of grains of sand are there in 6300 kg of sand is 90,000,000.
What is scientific notation?Scientific notation is a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power such as [tex]1.56\times10^7[/tex].
Given that, one grain of this sand approximately weighs [tex]7\times10^{-5}[/tex] g.
6300 kg of sand
Number of grains = [tex]\frac{6300}{7\times10^{-5}}[/tex]
= [tex]900\times10^5[/tex]
= 90,000,000
Therefore, the number of grains of sand are there in 6300 kg of sand is 90,000,000.

For any two real numbers, a and b one and only one of these relations is true:
1. a = b
2. a < b
3. a > b
Answer:
For real numbers according to the Law of Trichotomy,
if a = b then a will never be greater than b and a will never be less than a.
if a<b then a will never be equal to b and a will never be greater than b.
if a>b then a will never be less than b and a will never be equal to b.
And vice versa to b as well.

solve for x : -4 = (2/3)x
show steps please
To solve for x, we have to find a way to make x the subject of the equation (get x on one side and everything else on the other side)
since -4 = (2/3)x [mutiply both sides by 3]
⇒ -4 × 3 = 2x [divide both sides by 2]
⇒ (-12/2) = x [simplify by dividing -12 by 2]
∴ x = -6
Answer:
X = 6
Step-by-step explanation:
2/3 x 6/1 = 4
2 x 6 = 12
3 x 1 = 3
12/3 = 4
12 divided by 3 is 4
The answer is 6 , x = 6
