Mathematics

Answer:

m = - 1 and b = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line

m = \frac{-3-2}{2-(-3)} = \frac{-5}{2+3} = \frac{-5}{5} = - 1

b is the y- intercept, that is where the graph crosses the y- axis.

line crosses the y- axis at (0, - 1 ) ⇒ b = - 1

Solve for n: 7(n - 6) = a(n + 5)
Morgarella [4.7K]

Answer:

n = \frac{(5a + 42)}{( 7 - a ) }

Step-by-step explanation:

7(n - 6) = a(n + 5)

7n - 42 = an + 5a

7n - an = 5a + 42

n( 7 - a ) = 5a + 42

n = \frac{(5a + 42)}{( 7 - a ) }

Answer:  Step 5

===================================================

Reason:

The order of operations is PEMDAS

  • P = parenthesis
  • E = exponents
  • M = multiplication
  • D = division
  • A = addition
  • S = subtraction

The multiplication and division are on the same level of precedent, and the same goes for addition and subtraction. Some math textbooks may refer to PEMDAS as BODMAS, which is basically the same thing.

Notice how division comes before addition. So we must compute the 10 \div 2 portion first before adding in step 4.

This is what steps 4 and onward should look like

2 + 10 \div 2\\\\2 + 5\\\\7

So that's why the error is in <u>step 5</u>

If there was parenthesis around the "2+10", and we had (2+10) \div 2, then step 5 given by your teacher would be correct.
