Write as a Vector Equality D=3s-7t , s=-4 , t=2

Problem

D=3*s−7*t,s=−4,t=2

Solution

1. Identify the given vector equation and the scalar values provided for the vectors s() and t

2. Substitute the value −4 for s() and the value 2 for t into the expression for D

D=3*(−4)−7*(2)

3. Multiply the coefficients by the substituted values.

D=−12−14

4. Simplify the expression by performing the subtraction to find the resulting value for D

D=−26

Final Answer

D=3*(−4)−7*(2)=−26
