They're called variables (this sounds like vary because the number that a letter could represent varies) so when i say 1 + x = 3 it is saying that they don't know the value of x yet but of course you can solve that by subtracting 1 from 3 which is 2
Answer:
6 hours
Step-by-step explanation:
48 + 8.80
56.8 + 8.80
65.6 +8.80
74.4 + 8.80
83.2 +8.80
92 + 8.80
100.8
The answer would be simplified to q-8 after combining the like terms (:
Answer:
Option C. 
Step-by-step explanation:
we know that
The equation of the parent function f(x) (red graph) is
This is a vertical parabola open upward
The vertex is the point (0,0) (the origin)
The function g(x) (blue graph) is a vertical parabola open upward
The vertex is the point (-5,0)
The transformation of f(x) to g(x) has the following rule
f(x) -----> g(x)
(0,0) ----> (-5,0)
(x,y) ----> (x-5,y)
That means----> The transformation is a translation of 5 units at left
therefore
The equation of g(x) is
Answer:
x = -7
y = 1
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 7x = 3y - 52
[2] x = 3y/7 - 52/7
// Plug this in for variable x in equation [1]
[1] 4•(3y/7-52/7) + 3y = -25
[1] 33y/7 = 33/7
[1] 33y = 33
// Solve equation [1] for the variable y
[1] 33y = 33
[1] y = 1
// By now we know this much :
x = 3y/7-52/7
y = 1
// Use the y value to solve for x
x = (3/7)(1)-52/7 = -7
Solution :
{x,y} = {-7,1}
