Answer:
Perimeter=2L+2w
P=2(x+1)+2(x-3)
P=2x+2+2x-6
P=4x-4
Area=Lxw
A=(x+1)x(x-3)
A=x^2-3x+x-3
A=x^2-2x-3
Step-by-step explanation:

Answer:
19 - 8√3
Step-by-step explanation:
(-4 + √2)^2
= (-4)^2 + 2(-4)(√3) + √3)^2
= 16 - 8√3 + 3
= 19 - 8√3
Answer:
y= 0.25x +3
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept.
y= 0.25x -5
This equation is already in the slope-intercept form, hence we can easily identify its slope from the coefficient of x.
Slope= 0.25
Parallel lines have the same slope.
Thus, the slope of the line is also 0.25.
Substitute m= 0.25:
y= 0.25x +c
To find the value of c, substitute a pair of coordinates.
When x= 8, y= 5,
5= 0.25(8) +c
5= 2 +c
c= 5 -2
c= 3
Hence, the equation of the line is y= 0.25x +3.
Answer:
A. (2, -1)
Step-by-step explanation:
(4x - 9) - x = -3
3x - 9 = - 3
3x = 6
x = 2
y = 4(2) - 9
y = 8 -9
y = - 1
(2, -1)
Check
-1 - 2 = -3
So, 2 hours times 10 this is 20 hours. $180 divided by 20. This is 9.
Her hourly rate is $9.
Hope this helps :)
