Answer:
The equation of the line that passes through the point (2, -1) and has a slope of -3 will be:
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
Given
substituting m = -3 and the point (2, -1) in the slope-intercept form of the line equation
y = mx+b
-1 = -3(2)+b
-1 = -6 + b
b = -1 + 6
b = 5
Thus, the y-intercept form of the line equation is b = 5
now substituting b = 5 and m = -3 in the slope-intercept form of the line equation
y = mx+b
y = -3x + 5
Thus, the equation of the line that passes through the point (2, -1) and has a slope of -3 will be:
Answer:
No
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A triangle with some side measure .
- The sides are 4 ,6,7.
And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.
<u>Pythagoras</u><u> Theorem</u><u> </u><u>:</u><u>-</u><u> </u>
- In right angle triangle the sum of squares of the two smallest sides is equal to the square of the largest side .
Here the two smallest sides are 4 & 6 .
<u>Sum </u><u>of </u><u>Squares </u><u>of </u><u>4</u><u> </u><u>and </u><u>6</u><u> </u><u>:</u><u>-</u><u> </u>
4² + 6²
24 + 36
60
<u>Square</u><u> </u><u>of </u><u>7</u><u> </u><u>:</u><u>-</u><u> </u>
7²
49
<u>And </u><u>:</u><u>-</u><u> </u>
- They aren't equal. So the triangle is not a right angled triangle .
<u>Hence </u><u>the triangle is not a right angle triangle</u><u>.</u>
Answer:
area of the BCD triangle=1/2×10×9
=45
area of the ABD triangle=1/2×10×3
=15
Total area=45+15
=60 square centimetres
Answer:
Both the mean and median are greater for Plot A than for Plot B.
Step-by-step explanation:
Plot A data set is : 4,4,5,5,6,6,7,7,10
mean(Plot A) = 5.7
median(Plot A) = 5.5
Plot B data set is : 4,4,5,5,5,6,6,6,7
mean(Plot B) = 5.1
median(Plot B) = 5
Both the mean and median are greater for plot A than for plot B.
