a.
93%

b.
92%

c.
95%

d.
94%

which is the solution of the equation below, rounded to the nearest tenth?

2.1x – 4.09 = 6.98x + 1.73

a.
–0.5

b.
–1.2

c.
–0.4

d.
–1.1

solve the formula for the variable y.

z = 4x + 2y

: d

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
