Answer:
y= 2x
Step-by-step explanation:
(0,0) and (2, 4)
m= (y2-y1)/ (x2-x1)
m= (4-0)/(2-0)
m= 4/2
m=2
y- y1= m(x -x1)
y - 4= 2(x - 2)
y-4= 2x - 4
y= 2x
Answer:
Step-by-step explanation:
y=mx+b where m is the slope and b is the y intercept. Since there is point (0,0) we know that b=0 so we only need to find m
m=(y2-y1)/(x2-x1)
m=(4-0)/(2-0)=4/2=2 so the line is
y=2x
The value of the computer decreased exponentially throughout the five-year
period. What was the average annual amount of decrease in dollars per
year) over the two-year interval from t = 2 to t = 4?
(Note: Give the answer as a positive value.
Answer:
See Explanation
Step-by-step explanation:
Incomplete question as the function is not given. So, I will give a general solution
Required
Determine the average rate of change from t = 2 to 4
Average rate of change is :
[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]
In this case: a = 2 and b = 4
So, we have:
[tex]Rate = \frac{f(4) - f(2)}{4 - 2}[/tex]
[tex]Rate = \frac{f(4) - f(2)}{2}[/tex]
Assume that the exponential function is:
[tex]f(t) = 3^{-t[/tex]
f(4) and f(2) will be:
[tex]\\ f(4) = 3^{-4} = \frac{1}{81}[/tex]
[tex]f(2) = 3^{-2} = \frac{1}{9}[/tex]
So:
[tex]Rate = \frac{f(4) - f(2)}{2}[/tex]
[tex]Rate = \frac{\frac{1}{81} - \frac{1}{9}}{2}[/tex]
Take LCM
[tex]Rate = \frac{\frac{1 - 9}{81}}{2}[/tex]
[tex]Rate = \frac{-\frac{8}{81}}{2}[/tex]
[tex]Rate = -\frac{8}{81}*\frac{1}{2}[/tex]
[tex]Rate = -\frac{4}{81}[/tex]
So, the average rate of change is a decrease of 4/81
Drag numbers to write an equation for the line slope-intercept form. Numbers may be used once, more than once, or not at all.
Answer:
y = -3x + 5
Step-by-step explanation:
Find the graph attached
The standard form of calculating the equation of a line is expressed as;
y = mx+c
m is the slope
c is the intercept
Using the coordinate points (0, 5) and (1, 2)
m = 2-5/1-0
m = -3/1
m = -3
Get the intercept
Substitute m = -3 and (0,5) into y = mx+c
5 = -3(0) + c
5 = c
c = 5
Get the required equation
Recall that y = mx+c
Substitute the gotten values
y = -3x + 5

Possible answers:
a. There is a positive linear association in this scatterplot. This means that as family size increases, then the number of loads of laundry that needs to be done also increases.
b. There is a nonlinear association in this scatterplot. This means that as family size increases, then the number of loads of laundry that needs to be done also increases.
c. There is a negative linear association in this scatterplot. This means that as family size increases, then the number of loads of laundry that needs to be done decreases.
d. There is a positive linear association in this scatterplot. This means that as family size increases, then the number of loads of laundry that needs to be done decreases.
Answer:
Your answer is A
Step-by-step explanation:

Answer:
[tex]x= 15[/tex]
Step-by-step explanation:
Francisca's mistake was that when she had an equation [tex]5 = \frac{1}{3} x[/tex] instead of dividing both sides by [tex]\frac{1}{3}[/tex] she substracted [tex]\frac{1}{3}[/tex] from both sides. So the correct way would be...
[tex]5 = \frac{1}{3} x\\\\(5)(3) = (\frac{1}{3} x )(3)[/tex]
[tex]15 = x[/tex]

Solve (x + 1 < 5) ∩ (x - 4 > -3).
{ x | x < 4 or x > 1}
{ x | 1 < x < 4}
{all real numbers}
Answer:
{all real numbers}
Step-by-step explanation:
Solve (x + 1 < 5) ∩ (x - 4 > -3).
For the expression
x + 1 < 5
Subtract 1 from both sides
x+1-1 < 5-1
x < 4
For the inequality
x - 4 > -3
Add 4 to both sodes
x-4+4 > -3 + 4
x > -1
Hence the intersection of both is on all real numbers since the value of x is greater than -1.

Mr. Jones sent his kids to Mt. Olympus. He gave each of his 5 children money for the day that included money for 4 drinks, 3 sandwiches, 2 treats, and $25 for the ticket in to the park.
If drinks (d) cost $1.50, sandwiches (s) cost $2, treats (t) costs $1, What is the total amount of money Mr. Jones gave to all five of his children?
Answer:
195
Step-by-step explanation:
4 drinks = 1.5 * 4 = 6.
3 sandwiches = 2 * 3 = 6
2 treats = 1 * 2 = 2
$6+$6+$2+$25 = 39
Multiply by 5 for each kid
39*5=195

What are the coordinates of the point on the directed line segment from (-10, 10)(−10,10) to (-5, 5)(−5,5) that partitions the segment into a ratio of 2 to 3?
Answer:
(-7, 7)
Step-by-step explanation:
The formula for calculating the coordinate point is expressed as;
M(X, Y) = (ax1+bx2/a+b, ay1+by2/a+b)
X = ax1+bx2/a+b
X = 2(-10)+3(-5)/2+3
X = -20-15/5
X = -35/5
X = -7
Y = ay1+by2/a+b
Y = 2(10)+3(5)/2+3
Y = 20+15/5
Y = 35/5
Y = 7
hence the required coordinate is (-7, 7)
A middle school has a student population of 800 students. A random group of 60 students at the school were asked if they would vote for a tiger as a school mascot.
