So I just did 3x-20=223

3x=243

x=243/3

x=81

so the answer would be 81

Answer:

81

Step-by-step explanation:

Let the number be y.

20 less than 3 times y = 223

The expression is thus

3y - 20 = 223

Add 20 to both sides to eliminate -20 on the left

3y -20 + 20 = 223 + 20

3y = 243

Divide both sides by 3 to isolate y

3y/3 = 243/3

y = 81

The number is 81

Part A:

Function A:

Slope = (7-3)/(5-3) = 4/2 = 2

Equation:

y - 3 = 2(x - 3)

y - 3 = 2x - 6

y = 2x - 3

Funcion B:

(0, 3 ) and (-5, 0)

Slope = (3 - 0)/(0 + 5) = 3/5

y-intercept (0,3) so b = 3

Equation:

y = 3/5 x + 3

Function C:

y = 3x + 1

Part B:

Rate of change is the change in y over the change in x (rise/run). It's also the slope

Function A:     rate of change = 2

Function B:     rate of change = 3/5 (smallest)

Function C:     rate of change = 3   (largest)

Order linear functions based on rate of change from least to greatest.

Function B:             y = 3/5 x + 3

Function A:             y = 2x - 3

Function C:             y = 3x + 1

How many solutions does this linear system have? y =2/3 x+ 2 6x – 4y = –10
ZanzabumX [31]
2.  They are both straight lines.  The solution of a linear system is where the two lines intersect, and if they're both straight lines, then they can only cross once.
