Answer:
k = -7
Step-by-step explanation:
Step 1: Write equation
-k/5 = 7/5
Step 2: Solve for <em>k</em>
- Cross multiply: -5k = 35
- Divide both sides by -5: k = -7
Step 3: Check
<em>Plug in k to verify it's a solution.</em>
-(-7)/5 = 7/5
7/5 = 7/5
Answer:
try the option provided in the attachment.
(4y−3)(2y^2+3y−5)
=(4y+−3)(2y^2+3y+−5)
=(4y)(2y^2)+(4y)(3y)+(4y)(−5)+(−3)
(2y^2)+(−3)(3y)+(−3)(−5)
=8y^3+12y^2-20y-6y^2-9y+15
=8y^3+6y^2-29y+15
6 - 2x + 2y = 3x + 5
-2x + 2y = 3x - 1
-5X + 2y = -1
All your X's are positive so we multiply by -1
5X - 2y = 1
Answer:
-3
Step-by-step explanation:
y-5x = 3
use the commutative property to reorder the terms
-5x + y = 3
change the signs on both sides of the equations
-5x + y = -3
