Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)
Answer: y = -3.5x - 4.5
suppose: the equation of the line is y = ax + b ( a ≠ 0 )
because the line passes through (-2;2.5) => 2.5 = -2a + b
the line passes though (0;-4.5) => -4.5 = b
=> b = -4.5
2.5 = -2a + b
=> a = -3.5
b = -4.5
=> the equation of the line is y = -3.5x - 4.5

Tina has two rectangular playpens to keep her new pet dogs. The first rectangle has a width of 6 feet and a length of x - 4 feet. The second rectangle has a width of 8 feet and a length of x + 2 feet. What is the sum of the two perimeters?
Answer:
4x+24 ft.
Step-by-step explanation:
Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.
Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.
Add these two together: 2x+4 + 2x+20 = 4x+24. Don't forget to add units: 4x+24 ft.

This table represents the number of ounces, u, a kitten grows after w, weeks. When graphed, all of the points in the table lie on the same line. What is the slope and y-intercept of the line? slope=−23, y-intercept=−0.2 slope=32, y-intercept = 3 slope=23, y-intercept=−0.2 slope=−32, y-intercept = 3
Using the slope and intercept formula, the slope and y - intercept values of the graphed data are 3/2 and 3 respectively
Given the data :
Weeks, w ___ Weight in ounces, u
0 __________ 3
3 _________ 7.5
6 __________12
9 _________16.5
The y - intercept :
This is the value of y when the value of x = 0From the table given, the initial weight of the kitten (weight at week 0) = 3 ounces
Hence, the intercept is 3 ounces.
2.)
The slope :
Slope = Rise / RunRise = y2 - y1 = (16.5 - 3) = 13.5
Run = x2 - x1 = 9 - 0 = 9
Slope = 13.5 / 9 = 1.5
Therefore, the slope is 1.5

Mario walked at a rate of 5/6 miles every 10 minutes what is his unit rate every mile per hour
Answer:
Mario's unit rate is 5/1
Step-by-step explanation:
We know that Mario walks 5/6 miles per 10 minutes.
We need to find out how many miles Mario walks in 60 minutes (1 hour).
10 * 6 = 60. Which means that we must multiply 5/6 by 6.
[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]
30/6 = 5
Mario walks 5 miles per hour.
To put this in to a unit rate we must put this is a fraction:
[tex]\frac{Miles}{Hour}[/tex]
Substitute:
5/1
Answer:
Mario's unit rate is given by 900 miles/hour
Step-by-step explanation:
We have been given that Mario walked at a rate of 2/3 miles every 10 minutes
We have the relation between speed, time and distance, which is given by
speed = distance/Time
we have,
distance = 2/3 miles
Time = 10 minutes
On substituting these values in above formula, we got
speed 2/3 /10
speed 2/10.3
We have to find the unit rate in mile per hour, so we need to multiply it by 60
Thus, unit rate is given by
1/15 X 60
= 4 miles/hour

Answer:
y = mx + b
Step-by-step explanation:
Substitute in the slope intercept formula
m = slope
x = first number in the point
y = second number in the point
and solve for b
Question 1
m=-1/2, x= -4 y=-2 substitute
-4 = -1/2(-4) + b
-4 = 2 + b
-4 -2 = 2 -2 + b
-6 = b
y=-1/2x -6

of time mice take to complete a maze for a piece of cheese.
Is it plausible that the true mean number of times for all mice to complete this maze may be less than 7 minutes?
No, this is not plausible for the population mean because 7 minutes is within the 95% confidence interval.
O No, this is not plausible for the population mean because 7 minutes is not within the 95% confidence interval.
Yes, this is plausible for the population mean because 7 minutes is not within the 95% confidence interval.

Answer:
y= -3/4x-2
Step-by-step explanation:
- perpendicular: opposite signs and reciprocal
m= -3/4
point-slope form: y-y1=m(x-x1)
y-(-1)= -3/4(x-(-4))
y+1= -3/4(x+4)
