What is the Slope of 7x+4y=20

Mathematics
1 answer:
yKpoI14uk [10]3 years ago
8 0

<u><em>Answer:</em></u>

slope = \frac{-7}{4}


<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

\frac{4y}{4} = \frac{-7x}{4} + \frac{20}{4}

y = \frac{-7}{4} x + 5


<u>Now, comparing our equation with the general form, we would find that:</u>

m = slope = \frac{-7}{4}

c = y-intercept = 5


Hope this helps :)

A textbook store sold a combined total of 255 physics and math textbooks in a week. The number of math textbooks sold was 81 les
dimulka [17.4K]

Answer:

math = 87

physics = 168

<em>Brainliest, please!</em>

Step-by-step explanation:

Variables:

m = math, p = physics

Equations:

m + p = 255

m = p - 81

Substitution:

m + p = 255

(p - 81) + p = 255

2p - 81 = 255

2p = 336

p = 168

Solving for m:

m + p = 255

m + 168 = 255

m = 255 - 168

m = 87

Checking with the other equation:

m = p - 81

87 = 168 - 81

87 = 87

So, math = 87 and physics = 168
