<u><em>Answer:</em></u>
slope = 
<u><em>Explanation:</em></u>
<u>The general form of the linear line is:</u>
y = mx + c
where:
m is the slope
c is the y-intercept
<u>The given equation is:</u>
7x + 4y = 20
<u>We will start by putting the equation in the general form:</u>
7x + 4y = 20
4y = -7x + 20
y = 
<u>Now, comparing our equation with the general form, we would find that:</u>
m = slope =
c = y-intercept = 5
Hope this helps :)
Answer:
3x+3y−z−7
Step-by-step explanation:
"Let's simplify step-by-step.
4x+2y−z−(x−y+7)
Distribute the Negative Sign:
=4x+2y−z+−1(x−y+7)
=4x+2y+−z+−1x+−1(−y)+(−1)(7)
=4x+2y+−z+−x+y+−7
Combine Like Terms:
=4x+2y+−z+−x+y+−7
=(4x+−x)+(2y+y)+(−z)+(−7)"(Mathpapa)
The answer is none of the above
The length of the inside of the garden is<u> 50 feet.</u>
What is perimeter ?
A perimeter is a closed path that covers, surrounds, or outlines a two-dimensional shape or length. The circumference of a circle or an ellipse is its perimeter.
There are various practical applications for calculating the perimeter. A calculated perimeter is the length of fencing needed to completely encircle a yard or garden. The perimeter (circumference) of a wheel/circle describes how far it will roll in one revolution. Similarly, the amount of string wrapped around a spool is proportional to the spool's perimeter; if the string length were correct, it would equal the perimeter.
Given :
The rectangular garden has a perimeter of 280 feet
breadth = 90 feet
Let the length be x.
Therefore according to the question,
2( 90 + x ) = 280
=> 90+ x = 140
=> x = 50
