Answer:
6.67 is the awnser or 6.6666666666
Step-by-step explanation:
<span>Let x = the width
:
It says,"The length of a rectangle is 4 less than 3 times the width." write that as:
L = 3x - 4
:
If the perimeter is 40, find the dimensions of the rectangle.
:
We know: 2L + 2W = 40
:
Substitute (3x-4) for L and x for W
2(3x-4) + 2x = 40
:
6x - 8 + 2x = 40; Multiplied what's inside the brackets
:
6x + 2x = 40 + 8; do some basic algebra to find x; (added 8 to both sides)
:
8x = 48
:
x = 48/8
:
x = 6 which is the width
:
It said that L = 3x - 4, therefore:
L = 3(6) - 4
L = 18 - 4
L = 14; is the length
:
Check our solutions in the perimeter:
2(14) + 2(6) =
28 + 12 = 40</span>
y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)
<em><u>Solution:</u></em>
Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)
<em><u>The equation of line in slope intercept form is given as:</u></em>
y = mx + c ---- eqn 1
Where, "m" is the slope of line and "c" is the y - intercept
Given that, slope = m = 5
y intercept is (0, 4)
So, c = 4
<em><u>Substitute c = 4 and m = 5 in eqn 1</u></em>
y = 5x + 4
Thus the equation of line is found
The correct answer to this question is.....
A!!!
I hope this helped!!! (I took the test on it)
