Which of the following best describes the expression 2a + 3b + 4c + 5d?
a.) the product of four sums; there are four terms
b.) the product of four sums; there are eight terms.
c.) the sum of four products; there are four terms
d.) the sum of four products, there are eight terms

Option C The expression is the sum of four products; there are four terms

Step-by-step explanation:

we have

we know that

The expression is the sum of four terms

Each term is a product

so

there are four products

therefore

The expression is the sum of four products; there are four terms

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
