Answer:
The slope of the line is -2
Step-by-step explanation:
<em>The rule of the slope of a line is</em>:
, where
and 
are two points on the line
<em>Let us find the slope using the rule above</em>
∵ The line passes through points (3, -7) and (-1 , 1)
∴ 
= 3 and 
= -1
∴ 
= -7 and 
= 1
<em>Substitute these values in the rule above to find m</em>
∴ 
∴ The slope of the line that passes through the given points is -2
Answer:
She drove 3 hours
Step-by-step explanation:
Leslie drove 2/3 of the 4 1/2 hours trip. To determine how long she drove, multiply these numbers together.
2/3 * 4 1/2
We need to change the second number to an improper fraction
4 1/2 = (2*4 +1)/2 = 9/2
2/3 * 9/2 = 9/3 = 3
She drove 3 hours
They give you an "x =" statement so you plug in the right side of the equals sign into the first equation wherever x appears. So...
y = 10 - 2(y - 4)
y = 10 - 2y + 8
y = 18 - 2y
y + 2y = 18
3y = 18
y = 6
Now we plug in this result for the y-value into the "x =" statement.
x = 6 - 4
x = 2
Your answer is (2, 6)
1. The remaing area of the yard will be found as follows:
Area of the yard
A1=length*width=10x*15x=150x^2 yd^2
area of the fountain
A2=πr²
A2=π(4x)²
=50.266x^2
The remaining area will be:
A=150x^2-50.266x^2
A=99.735x^2 yd^2
2] Area left for bleachers, restrooms and other parts of the stadium will be as follows:
Area of the lot is:
A1=length*width
A1=8x×12x= 96x^2
Area of the field
A2=length×width
A2=3x×6x=18x^2
Hence the remaining area will be:
A1-A2
=96x^2-18x^2
=78x^2 sq. units
