Alright, so first we'll have to get y on the other side
So
2x+y=-9
-y -y
+9 +9
2x+9=-y
Then divide is all by -1 so y is positive
-2x-9=y
Answer:
1. c=-2
2. 0=12 no solution
3. x=4
4. r=3/2
Step-by-step explanation:
Answer:
5x^4+ 2x^3+3x² – 3x + 2
Step-by-step explanation:
(5x^4+ 2x^3– 1)+(3x² – 3x + 3)
Combine like terms
5x^4+ 2x^3+3x² – 3x + 3– 1
The only like terms are the constants
5x^4+ 2x^3+3x² – 3x + 2
Answer:
2√42 ≈ 12.961
Step-by-step explanation:
All of the right triangles are similar, so ...
short leg/long leg = BC/AC = AC/CD
AC² = BC·CD = 7·24 = 168
AC = √168 = 2√42
Answer: The answer to your question is 6
Step-by-step explanation:
To solve this problem we will use proportions. We will compare the largest right triangle and the medium size triangle.
Medium triangle Large triangle
hypotenuse y 9 + 3
adjacent size 9 y
- Write the proportions
y/9 = (9 + 3)/y
-Solve for y
y² = 9(12)
y² = 108
y = 
-Find the prime factors of 108
108 2
54 2
27 3
9 3
3 3
1
then, 108 = 2² 3³
-Expressthe root as fractional exponents
2²/² 3²/² 3¹/²
-Simplification
2(3)(3)¹/²
-Result
6
