Question

Evaluate the expression for g = –14, h = –10, and j = 5.

g + h − j =

Answer 1

To evaluate the expression \( g + h - j \) for \( g = -14 \), \( h = -10 \), and \( j = 5 \), we can substitute the values into the expression.

\[
g + h - j = -14 + (-10) - 5
\]

Now, we perform the calculations step by step:

1. Add \( g \) and \( h \):
\[
-14 + (-10) = -14 - 10 = -24
\]

2. Next, subtract \( j \):
\[
-24 - 5 = -29
\]

Therefore, the final result is:
\[
g + h - j = -29
\]

Answer 2

Evaluate the expression for c = –4, d = –2, and f = –3.

cdf =

Answer 3

To evaluate the expression \( c \cdot d \cdot f \) with the given values \( c = -4 \), \( d = -2 \), and \( f = -3 \), we can substitute the values into the expression:

\[
cdf = (-4) \cdot (-2) \cdot (-3)
\]

Now, let's perform the calculations step by step.

1. First, multiply \( c \) and \( d \):
\[
(-4) \cdot (-2) = 8
\]

2. Next, multiply the result by \( f \):
\[
8 \cdot (-3) = -24
\]

Therefore, the final result is:
\[
cdf = -24
\]

Answer 4

Evaluate the expression for x = 0 and y = 5.

–2y 2 to sec power − x =

Answer 5

To evaluate the expression \(-2y^2 - x\) for \(x = 0\) and \(y = 5\), we can substitute the values into the expression.

First, calculate \(y^2\):

\[
y^2 = 5^2 = 25
\]

Now, substitute \(y^2\) and \(x\) into the expression:

\[
-2y^2 - x = -2(25) - 0
\]

Now simplify:

\[
-2(25) = -50
\]

Thus:

\[
-50 - 0 = -50
\]

Therefore, the final result is:

\[
-2y^2 - x = -50
\]

Answer 6

Evaluate the expression for w = –10 and x = –3.

wx + x =

Answer 7

To evaluate the expression \( wx + x \) with \( w = -10 \) and \( x = -3 \), we first substitute the values into the expression:

\[
wx + x = (-10)(-3) + (-3)
\]

Now, calculate it step by step:

1. First, calculate \( wx \):
\[
(-10)(-3) = 30
\]

2. Next, add \( x \):
\[
30 + (-3) = 30 - 3 = 27
\]

Thus, the final result is:

\[
wx + x = 27
\]

Answer 8

Evaluate the expression for w = 6, x = –2, and y = 3.

wxy =

Answer 9

To evaluate the expression \( wxy \) with \( w = 6 \), \( x = -2 \), and \( y = 3 \), we can substitute the values into the expression:

\[
wxy = 6 \cdot (-2) \cdot 3
\]

Now, let's perform the calculations step by step:

1. First, multiply \( w \) and \( x \):
\[
6 \cdot (-2) = -12
\]

2. Next, multiply the result by \( y \):
\[
-12 \cdot 3 = -36
\]

Therefore, the final result is:
\[
wxy = -36
\]

Answer 10

Evaluate the expression for c = –4 and d = 8.

cd + d =

Answer 11

To evaluate the expression \( cd + d \) with \( c = -4 \) and \( d = 8 \), we can substitute the values into the expression:

\[
cd + d = (-4)(8) + 8
\]

Now, let's calculate it step by step:

1. First, calculate \( cd \):
\[
(-4)(8) = -32
\]

2. Next, add \( d \):
\[
-32 + 8 = -24
\]

Therefore, the final result is:
\[
cd + d = -24
\]
