Answer:
x = -4
Step-by-step explanation:
Simplifying
2[x + 4] = 2[-8 + -1x] + -2x
Reorder the terms:
2[4 + x] = 2[-8 + -1x] + -2x
[4 * 2 + x * 2] = 2[-8 + -1x] + -2x
[8 + 2x] = 2[-8 + -1x] + -2x
8 + 2x = [-8 * 2 + -1x * 2] + -2x
8 + 2x = [-16 + -2x] + -2x
Combine like terms: -2x + -2x = -4x
8 + 2x = -16 + -4x
Solving
8 + 2x = -16 + -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
8 + 2x + 4x = -16 + -4x + 4x
Combine like terms: 2x + 4x = 6x
8 + 6x = -16 + -4x + 4x
Combine like terms: -4x + 4x = 0
8 + 6x = -16 + 0
8 + 6x = -16
Add '-8' to each side of the equation.
8 + -8 + 6x = -16 + -8
Combine like terms: 8 + -8 = 0
0 + 6x = -16 + -8
6x = -16 + -8
Combine like terms: -16 + -8 = -24
6x = -24
Divide each side by '6'.
x = -4
Simplifying
x = -4
Answer:
87
Step-by-step explanation:
Complementary angles add to 90 degrees
Let c be the complement
c + 3 = 90
Subtract 3 from each side
c+3-3 = 90-3
c = 87
Answer: 12
Step-by-step explanation:
Given:
A = 452
r = √A/3
Step 1: Substitute 452sqf for A
r = √452/3
Step 2: Solve
452 ÷ 3 = 150.66∞
√150.66∞ = 12.27∞
12.27∞ rounded to the nearest integer equal 12
Part 1: the function would be
h(t)= -16t^2+15t+6.5
Part 2: using the same steps it stated on the calculator
x=1.26
Part 3: by using t= -b/(2a) 15 as b and -16 as a makes it
t= 15/32
Part 4: You then put 15/32 in for t in the equation making the maximum height
10.02
IDK IF THIS IS RIGHT BUT IVE SPENT ALL DAY ON THIS
The answer is B.
The formula for axis of symmetry is -b/2a.
The b value is -8 and the a value is 1.
Plug it in.
-(-8)/2(1)
8/2(1)
8/2=4
