1. what is the equation of a line that has an x-intercept of 2 and a y-intercept of 8

Phoenix [80]

Answer:

Step-by-step explanation:

x- intercept = 2 .So, Coordinate(2 , 0)

y-intercept = 8 . So, Coordinate (0, 8)

$Slope = \frac{8-0}{0-2}\\\\=\frac{8}{-2}\\\\=-4$

Slope y-intercept form: y = mx + b {Here, b is y-intercept}

y = -4x + 8

6 + 2/5b = 12 What does “b” equal?

Elis [28]

Answer:

B = 15

Step-by-step explanation:

Combine multiplied terms into a single fraction

6 + 2b/5 = 12

Subtract 6 from both sides

6 + 2b/5 (-6) = 12 (-6) = 2b/5 = 6

Multiply all terms by the same value to eliminate fraction denominators

2b/5 ( x 5) = 6 (x 5)

Simplify

2b = 30

diamong [38]

Answer:

negative 21/9 times negative 18/7 is 6

Step-by-step explanation:

The phrase negative 21/9 times negative 18/7 can be written mathematically as

$-\frac{21}{9} \times -\frac{18}{7}$

Lets first convert the fractions into decimal values

$-\frac{21}{9}$ = -2.33

$-\frac{18}{7}$ = -2.57
