Short answer 4 units to the right.RemarkGraph the two equations.
The purple graph is y = x^2
The black graph is y = (x - 4)^2
Rule1. When a constant is inside the brackets, the graph moves left or right. To tell which use the second part of the rule.
2. use y = (x + a)^2 as your example.
if a > 0 the graph moves left.
if a < 0 then graph moves right.
Just the opposite of what you would expect.
Answer:
-52, -69, -89, -100, -124
Step-by-step explanation:
Answer:
$46.25
Step-by-step explanation:
3/8 of 25 is 9 3/8 gal
25-9 3/8 = 15 5/8
15 5/8 x 2.96 = 46.25
Answer:
y=3,x=1.3,z=6.2 :)
Step-by-step explanation:
y=3,x=1.3,z=6.2 :)
So, we have:
: x+y+z=10 [equation 1]
: 5x+3y=14 [equation 2]
: x−2y+z=2.5 [equation3]
(I'm going to assume that you know how to solve equations with 2 variables)
1. eliminate a variable to get 2 variables
Let's reverse equation 2:
-x+2y-z= -2.5
and take equation 1, to try to eliminate "z"
x+y+z=10
add up the 2 equations to get:
3y=7.5
and solve to get
y=2.5
2. substitute what we already solved into another equation
Luckily, equation 2 only has 2 variables, and one is y, so we can sub it in.
5x+3y=14 --> 3x+3(7.5)=14
solve to get
x=1.3
3. Substitute both of our variables in to get the final variable: z
Let's take the first equation.
x+y+z=10 --> 1.3+2.5+z=10
solve to get
z=6.2
I hope this helps you!
