Answer:
-3/2
Step-by-step explanation:
Given the funtion
(2x+3)² - 6x+9 = 0
(2x+3)² = 6x + 9
Expand
4x²+12x+9 = 6x + 9
4x²+12x - 6x = 0
4x²+6x = 0
4x² = -6x
4x = -6
x = -6/4
x = -3/2
Hence the value of x is -3/2
Answer:
b=7
Step-by-step explanation:
Plug 3 into a since a=3.
2(3)+b=13
Then solve for 2(3)
6+b=13
Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)
b=13-6
b=7
Answer: 7.29π mm²
Step-by-step explanation:
First, I am assuming XY is the diameter of the circle :)
The formula for the area of a circle is πr² (r = radius)
So that means we need to divide the diameter by 2 to find the radius
5.4 / 2 = 2.7
Now we simply plug in our numbers!
3.14 · 2.7²
3.14 · 7.29
And that's it!
Hope this helped you :)
Hey there!
<h2>
ANSWER: 
</h2><h2>
EXPLANATION:</h2>
All numbers are positive except -1. If a number is negative, then that negative number will be less than a positive. All are positive and -1 is negative. Since that's the only negative, -1 is the smallest number.
Hope this helps!
I assume you are trying to solve for each variable. if thats the case you want to use one equation to solve for y and then plug the y value into the next variable
Problem: y =-3x=4 so -3x+4=3x-2
x=1
plug x value into one of the equations
y=3(1)-2
y=1
