Answer:
Step-by-step explanation:
Given the function :
f(x) = 7x - 8
Evaluate the given values of the independent variable and simplify.
a. f(7)
b. f(x + 5)
c. f(-x)
A.) f(7)
f(7) = 7(7) - 8
= 49 - 8
= 41
B.) f(x + 5)
7(x + 5) - 8
7x + 35 - 8
7x - 27
C.) f(-x)
7(-x) - 8
-7x - 8
Answer:
Step-by-step explanation:
T\The answer would be 3 6/10, or 3.6.
<span>Conisdering that the points labeld are (-4,-1) and (1.5, 2) this is how you find the equation of the line:
slope, m = (- 1 - 2) / ( - 4 - 1.5) = - 3 / - 5.5 = 6/11
Equation: [ y - (- 1) ] = (6/11) [ x - (-4)]
=> 11(y + 1) = 6(x + 4)
=> 11y + 11 = 6x + 24
=> 6x - 11 y + 13 = 0
=> 6x - 11y = - 13 <----- answer

Answer:
5 and 7.
Step-by-step explanation:
Hey! So to start you need to create an algebraic expression. You can express this problem through the following equation:
*Note: if x is an odd integer, x + 2 is the next consecutive odd integer.
Expanding, you get:
And moving the 35 to the other side, you get a simple quadratic.
Solving by factoring:
This means two possible solutions for the smaller consecutive number are -7 and 5. However the question asks for two positive odd integers, so one of the numbers must be 5. The next will be 7(as its x + 2).
