Let the three numbers be x, y and z respectively, then
x + y + z = 62 . . . (1)
y = x - 4 . . . (2)
z = 4x . . . (3)

The above three expressions could be used to represent the numbers.

Solving the three equations, putting (2) and (3) into (1) gives
x + x - 4 + 4x = 62
6x - 4 = 62
6x = 62 + 4 = 66
x = 66/6 = 11
x = 11.
y = 11 - 4 = 7
z = 4(11) = 44

x = 11, y = 7, z = 44.

If a and b are real numbers and if y = ax + b is a direct variation equation, what do you know about a and b?
Alenkasestr [34]
y = ax + b
 We observe that the given equation is the generic equation of a line.
 Where,
 a = represents the slope of the line. That is, the rate of change of the given function. (in this case it is constant).
 b = is the cut point with the y axis.

Write a rule for a geometric sequence that has -6 as its first term and a common ratio of 2. What is the tenth term of this sequ
slega [8]
The general form of the geometric sequence is a_{n} = a_{1} (r) ^{n-1}, where a sub n is the number term you're looking for (we're looking for the tenth term). a sub 1 is the first term in the sequence (ours is -6), r is the common ratio, and n-1 is the numbered term you're looking for minus 1.  Our formula then looks like this: a_{10} =-6(2) ^{10-1}.  Simplify it to  a_{10} =-6(2)^9.  Take 2 to the 9th power then multiply it by -6 to get -3072.  C is your answer.

G(x) = 3x + 1<br><br>f(x) = 2x - 5<br><br> Find g (f (x))​
sammy [17]

Answer:

g(f(x)) = 6x - 14

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Function Composition

Step-by-step explanation:

<u>Step 1: Define</u>

g(x) = 3x + 1

f(x) = 2x - 5

<u>Step 2: Find</u>

  1. Substitute:                    g(f(x)) = 3(2x - 5) + 1
  2. Distribute 3:                  g(f(x)) = 6x - 15 + 1
  3. Combine like terms:    g(f(x)) = 6x - 14

Consider the function RX) = 3x + 1 and the graph of the function g(x) shown below.
aleksandrvk [35]

Step-by-step explanation:

f(x) goes through the point (0, 1).

g(x) goes through (2, 1) for the same y value.

that means g(x) is f(x) translated 2 units to the right.

but we could also look at the same x value (0).

then g(x) goes through (0, -5).

and that means g(x) is f(x) translated 6 units down.

since it is a line function, shifting it left/right or up/down makes no difference to the shape or position of the new curve itself.

as it looks like you don't have 6 in the drop-down menu, then 2 units (to the right) is the desired correct result.

that means g(x) = f(x-2) = 3(x-2) + 1 = 3x - 6 + 1 = 3x - 5

and that is what the graph is showing us.
