Answer:
Infinite Solutions
Step-by-step explanation:
x + 2y = 10
6y = 3x - 30
To solve for x and y we use substitution method
Let's solve the first equation for x
x + 2y = 10
Subtract 2y on both sides
x = 10 - 2y
Now plug in x in second equation
6y = -3x + -30
6y = -3 (10-2y) - 30
6y = -30 + 6y - 30
6y = 6y
Both sides are the same, so both x and y have infinite solutions.
Hi There!
Answer:
A.)$15.96
Step-by-step explanation:
3 1/3 * 2.99 = 9.96666666667
1 1/2 * 3.99 = 5.985
9.9666666666 + 5.985 = 15.9516666667 = $15.96
Hope This Helps :)
Answer:Alden is 13 years old
Step-by-step explanation
Let x represent Alden's age.
Let y represent the age of his sister.
Let z represent the age of his second sister.
His sister is 5 years older than he is and 3 times as old as his second sister. This means that
y = x + 5
y = 3z
Alden's brother is 4 years younger than his second sister. It means that his brother's age is
z - 4
His brother is 2. It means that
z - 4 = 2
z = 2 + 4 = 6
y = 3z
y = 3 × 6 = 18
Substituting y = 18 into y = x + 5, it becomes
18 = x + 5
x = 18 - 5 = 13
The correct equation for this transformation is given as (x, y) ⇒ (x - 9, -(y + 2))
<h3>What is a
transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>reflection, translation, rotation and dilation.</em>
Translation is the movement of a point either<em> up, down, left or right</em> on the coordinate plane.
The graph of √(5x - x²) was translated 9 units left and 2 units up, then reflected over the x axis to get the new graph.
The correct equation for this transformation is given as (x, y) ⇒ (x - 9, -(y + 2))
