What is 5(4x+12)+3x+2

Mathematics
1 answer:
yulyashka [42]3 years ago
5 0

Answer:

23 x + 62

Step-by-step explanation:

Simplify the following:

5 (4 x + 12) + 3 x + 2

5 (4 x + 12) = 20 x + 60:

20 x + 60 + 3 x + 2

Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):

(20 x + 3 x) + (60 + 2)

20 x + 3 x = 23 x:

23 x + (60 + 2)

60 + 2 = 62:

Answer:  23 x + 62

Find the equation of the line.
s2008m [1.1K]

Answer:

y = -\frac{1}{3}x+5

Step-by-step explanation:

Let the equation of the given line is,

y = mx + b

where 'm' = slope of the line

b = y-intercept of the line

Since slope of a line passing through two points (x_1, y_1) and (x_2, y_2) is represented by,

m = \frac{y_2-y_1}{x_2-x_1}

If the points are (0, 5) and (-3, 6),

Slope of the line 'm' = \frac{6-5}{-3-0}

                                 = -\frac{1}{3}

y-intercept of the line 'b' = 5

Therefore, equation of the given line will be,

y = -\frac{1}{3}x+5

If y=4x+2 and x=1, we can get 4*1+2=6 for y, resulting in 1*6+1/6=2+z. Subtracting 2 from both sides, we get 4+1/6=z
