Step-by-step explanation:
3(7 + x) = 3×7 + 3x = 21 + 3x
remember, when you multiply two expressions, you need to multiply every term of the first expression with every term of the second expression, and then add all partial results (by considering the individual signs, of course).
Answer:
2/5
slope is the "inclination" of a line, so to be parallel they must have the same slope
Given
Required
First, calculate h(xc)
If
Then
Solving further:
Substitute h(xc) for x
Substitute
y = 6, z = 3
Substitute values into the expression:
Simplify both fractions:
Add the fractions:
[tex]\frac{8}{9}
