Answer: 47

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

<u>Given information</u>

x = 6

<u>Given expression</u>

4 (2x - 1) + 3

<u>Substitute values into the expression</u>

=4 [2 (6) - 1] + 3

<u>Simplify by multiplication</u>

=4 (12 - 1) + 3

<u>Simplify by subtraction</u>

=4 (11) + 3

<u>Simplify by multiplication</u>

=44 + 3

<u>Simplify by addition</u>

=\boxed{47}

Hope this helps!! :)

Write the slope-intercept form of the equation of the line perpendicular to the graph of y=-3/2x-7 that passes through (3,-2)
ozzi
Graph of y = -3/2x - 7 has a slope of -3/2.
For perpendicular lines the product of the slopes is -1.
m1m2 = -1
-3/2m2 = -1
m2 = -1/(-3/2) = 2/3

The required equation,
y - (-2) = 2/3(x - 3)
y + 2 = 2/3x - 2
y = 2/3x - 4
