Step-by-step explanation:
y = Total number of miles driven
= Number of days * Number of miles per day
= (x) * (300).
Therefore the equation is y = 300x.
When x = 2, y = 300(2) = 600.
The Nguyen family drove 600 miles during the 2 days.
What is the slope of a line perpendicular to the line whose equation is 2x+10y=20. Fully reduce your answer.
Answer:
m=5
Step-by-step explanation:
2x+10y=20
10y=-2x+20
y=-1/5x+2
slope of this line=-1/5
(replace the denominator by the nominator and the nominator by the denominator and change the sign to the opposite one negative to positive)
slope of perpendicular line=5

Original price is $300; Discount is 25%
Answer:
$225
Step-by-step explanation:
25% of 300 is also 1/4 of 300 which is 75
you take the discounted price away from the original price
300-75=225
How does 10 x (-3)^24 simplify to positive 10 x 3^24 and not negative 10 x 3^24 ?
Answer:
Below.-
Step-by-step explanation:
Because when a negative is taken to an even power the results is positive.
So (-3)^24 is positive as 24 is even, and is the same as 3^24, and so the whole expression
10 * (-3)^24 = 10 ^ 3^24.

In this case, we need to substitute n with 10.
So, it is like this: f(10) = 3(10) + 4
f(10) = 3(10) + 4
f(10) = 30 + 4
f(10) = 34
A ton might weigh 2000 pounds. How many six grades might weigh 2000 pounds?
Answer:
25
Step-by-step explanation:
An average 6th grader weight 80 pounds and 2000/80 is 25
25 six graders might weigh 2000 pounds, considering the average weight of a six grader is 80 pounds.
Average is the mean value of the data. It is a measure of central tendency.
Given the following information:
A ton might weigh 2000 pounds.
We need to find the total number of six graders require to collectively weigh 2000 pounds.
Let the total number of six graders require = x
Consider the average weight of a six grader is 80 pounds.
Total weight= average weight of a six grader x total number of six graders x
Total weight= 80x
2000=80x
To calculate the value of x, divide 80 both the sides.
2000/80=80x/80
25=x
x=25
Thus, 25 six graders might weigh 2000 pounds.

Answer:
y =4(x-3)^2+2 => y=4x^2-24x+38
y=2(x-3)^2+4 => y=2x^2-12x+22
y=2(x+3)^2+4 => y= 2x^2+12x+22
Y= 4(x+3)^2+2 => y= 4x^2+24x+38

What is the distance between the points R(5, 7) and S(-2, 3)?
Answer:
Step-by-step explanation:
D
The distance between points is √65.
What is distance?The length of the line that connects two points is the distance between them. The distance can be determined by subtracting the coordinates that are not the same if the two points are on the same horizontal or vertical line.
The distance formula is used in analytic geometry to determine the distance between two lines, the sum of the lengths of all sides of a polygon, the perimeter of polygons on a coordinate plane, the area of polygons, and a variety of other measurements.
Given coordinates
R(5, 7) and S(-2, 3)
to find the distance between
the formula of distance for coordinates is
d = [tex]\sqrt{(y_{2} - y_{1} )^{2} + (x_{2} - x_{1} )^{2} }[/tex]
here y₂ = 3, y₁ = 7
x₂ = -2, x₁ = 5
substitute value in equation we get
d = [tex]\sqrt{({3 - 7 )^{2} + (-2 - 5 )^{2} }[/tex]
d = [tex]\sqrt{({-4 )^{2} + (-7 )^{2} }[/tex]
d = √(16 + 49)
d = √65
Hence the distance is √65.

Answer:
y<-2x-3
Step-by-step explanation:
Your first step is to find the equation of the line. You can see that the y-intercept is -3, therefore your b is -3. So now your formula looks like this:
y=mx-3
To find m, you substitute in an x value and its corresponding y value. When you do this you will get -2.
Now it looks like this:
y=-2x-3.
Now that you have the equation of the line, you can look at the inequality. Since the line is dotted, that means it is not included in the inequality. That mean it cannot contain an equal to. So the only options we have are < and >. Since the shaded area is to the left, which is the negative side, we can conclude that y<-2x-3 is the correct equation.
