Answer:
Find the exact value using trigonometric identities. a MP3, 45, 0.15
Step-by-step explanation:
so your answer is $45.15 that is how much it was before the discount :)
Here is the problem.....√(15x + 10) = 2x+3
to remove the square root, we do the opposite which is to square everything.
(√(15x + 10))² = (2x + 3)² (the square negates the square root)
15x + 10 = (2x +3)(2x + 3) (use the distributive property to continue)
15x + 10 = 4x² + 6x + 6x + 9 (combine like terms)
15x + 10 = 4x² + 12x + 9 (subtract 15x and 10 from each side)
-15x - 10 -15x - 10
0 = 4x² - 3x - 1 (factor completely)
(x - 1) (4x + 1) (set each to equal 0)
x - 1 = 0 4x + 1 = 0
x = 1 4x = -1
x = -1/4
place both into the equation to check for reasonableness...we see the negative number is not reasonable, but the x value of 1 is a solution.
answer is 1
Answer:
24a+6=12a
Step-by-step explanation:
6(4a+1)
24a+6
2a X 6= 12a
24a+6=12a
Answer:
The slope is -2
Step-by-step explanation:
convert to slope intercept form. the number or fraction by the x when in slope intercept form is the slope.
