Answer:

y = 3/7x - 6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Slope m = 3/7

Point (14, 0)

Step 2: Find y-intercept b

Substitute: 0 = 3/7(14) + b
Multiply: 0 = 6 + b
Isolate b: -6 = b
Rewrite: b = -6

Step 3: Write linear equation

y = 3/7x - 6

Alabama papas must average 80 on five test . Scores on the first four test were 81 73 84 and 76 what is the lowest score she can

Salsk061 [2.6K]

She has to score at least 86 on her fifth test.

Further explanation:

We will use the average formula to find the fifth value.

Given

$Average\ required=80\\x_1=81\\x_2=73\\x_3=84\\x_4=76\\x_5=?$

We have to find x5

The formula for average is:

$x=\frac{Sum\ of\ values}{Total\ number\ of\ values}\\Here,\\n=5\\So,\\x=\frac{x_1+x_2+x_3+x_4+x_5}{5}\\Putting\ values\\80=\frac{81+73+84+76+x_5}{5}$

$80*5=314+x_5\\400=314+x_5\\x_5=400-314\\x_5=86$

She has to score at least 86 on her fifth test.
