Evaluate the expression y - x + z for x = 4.7, y = 6, and z=0.68 y – X + z =
(Type an integer or a decimal.)

1.98

Step-by-step explanation:

y - x + z for

x = 4.7, y = 6, and z=0.68

6 - 4.7 +.68

1.3+.68

1.98

Step-by-step explanation:

given that,

Let's solve now

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
