What is an algebraic expression for each phrase? A. The product of 9 and a number t. B. The difference of a number x and 1/2 c. The sum of a number m and 7.1

a) 9 x t

b) x - 1/2c

c) m + 7.1

Step-by-step explanation:

STEP 1

Giving the algebraic expression  becomes

A- The product of 9 and a number t. =       9 X t

B. The difference of a number x and 1/2 c=     x  -  1/2 c

C.   The sum of a number m and 7.1  =      m + 7.1

Step 2

The answers are

a) 9 x t

b) x - 1/2c

c) m + 7.1

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)
