Answer:
x=4
Step-by-step explanation:
Step 1: Add 3x to both sides.
−5x+9+3x=−3x+1+3x
−2x+9=1
Step 2: Subtract 9 from both sides.
−2x+9−9=1−9
−2x=−8
Step 3: Divide both sides by -2.
−2x/−2=−8/−2
Recall that:
sin(A + B) = sinAcosB + cosAsinB
Therefore:
sin11°cos19° + cos11°sin19° = sin(11° + 19°)
= sin30° = 0.5
I hope this explains it.
Answer:
y = 13/3
Step-by-step explanation:
First input 10 as our x into the equation. So our new equation is 2(10) - 3y=7.
Once you simplify your equation would be 20 - 3y = 7. Subtract 20 from both sides. New equation is -3y = -13. Divide each side by -3. Your answer for y is 13/3.
Answer:
x = 8
Step-by-step explanation:
Lines plotted through the given points intersect at (x, y) = (8, -4).
The x-coordinate of the solution is 8.
Answer:
(x+y)²
Step-by-step explanation:
Given the expressions (x + y) and (x + y)².
We are to find the LCM of (x + y) and (x + y)²
Taking the factors as shown
(x+y ) || (x + y) (x + y)²
(x+y ) || 1 (x+y)
|| 1 1
Multiplying both factors to get the LCM
= (x+y)(x+y)
= (x+y)²
<em>Hence the LCM of (x + y) and (x + y)² is (x+y)²</em>
