Answer:
Equation: f(x) = -x² + 3
Step-by-step explanation:
If we want to find the roots/solve for <em>x</em>, we can either graph the problem or use quadratic formula to find when f(x) = 0:
To get the equation of the graph, our parent function is: f(x) = a(x - h)² + k, or f(x) = x². Since we are reflecting over the x-axis with a vertical stretch and vertically moving up to (0, 3), we are modifying <em>a</em> and <em>k</em> only.
You can solve it by several ways, but easiest and shortest would be "By Elimination"
So, subtract 2nd equation from 1st,
-2x = 20
x = -10
Substitute it in 2nd equation,
-3(-10) + 9y = -6
30 + 9y = -6
9y = -6 - 30
y = -36/9
y = -4
In short, Your Answer would be: (-10, -4)
Hope this helps!
I don’t understand what you’re asking. Do u want the total of how many shirts there are together?
Answer:
x=-
Step-by-step explanation:
subtract -3(2x-1)+8=15
-8 -8
_____________
-3(2x-1)=7
divide
then simplify
2x-1=
add both sides
2x-1+1=+1
simplify again
2x-1+1=+1=2x=
divide by 2
2x=
-2 -2
_________
2x÷2=1
x=-
Hello there! Given the equation, we can solve through a series of steps:
1. Convert
In this step, we convert the mixed numbers to make them improper:
2 x 4 + 1 = 9, which means -4 1/2 = -9/2
4 x 3 + 3 = 15, which means -3 3/4 = -15/4
2. Multiply
Now that we have the improper fractions, we can multiply accordingly:
(-9/2 • -15/4) = -135/8
3. Simplify
Since we have our result, we can simplify to a mixed number:
-135/8 = 16 7/8
Your final answer is 16 7/8. Hope this helps!
