Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
First, we combine like terms.
2-x = x-4
Next we move the variables to one side and the numbers to another
2x = 6
We divide by 2.
x = 3

Step-by-step explanation:
the number line : a potentially infinite horizontal line.
it shows all numbers, with 0 in the center, eher we are looking at it. the negative numbers go to the left of 0, with -1, -2, -3, ... going from right to left.
the positive numbers go to the right of 0, with 1, 2, 3 going from left to right.
point S = -14
and the distance to a point R (RS) is 10.
now, on such a line we can always go in 2 directions : left and right.
our starting point is S (-14).
going 10 units to the right (positive direction) we get to -4.
as -14 + 10 = -4
going 10 units to the left (negative direction) we get to -24.
as -14 - 10 = -24
so, R can be at -4 or -24.

I need help with three and four
Answer:
Step-by-step explanation:
Part 3 :
We simply expand the brackets
(a+b)² = (a+b)(a+b)
(a+b)(a+b) = a²+ab+ab+b² = a²+2ab+b²
This is part 3 done
Part 4:
We simply expand 3 brackets now:
(2x-1)³ = (2x-1)(2x-1)(2x-1)
We do the first 2 brackets first:
(2x-1)(2x-1) = 4x²-2x-2x+1 = 4x²-4x+1
Now we multiply this by the last bracket:
(4x²-4x+1)(2x-1) = 8x³ -4x²-8x² +4x+2x -1 = 8x³-12x²+6x-1
This is part 4 done

Suppose that $5500 is placed in an account that pays 2% interest compounded each year.
Assume that no withdrawals are made from the account.
Follow the instructions below. Do not do any rounding.
(a) Find the amount in the account at the end of 1 year.
(b) Find the amount in the account at the end of 2 years.
Х
?
Answer: After 1 year: $5,610
After 2 years: $5,722.20
Step-by-step explanation: Use the formula for periodic compounding interest, which is
A = P(1 + r/n)^(nt), where A is the final amount, P is the initial deposit, r is the interest rate as a decimal, n is the number of times the interest is compounded per year, and t is how many years.
Here, P = 5,500, r = 0.02 (that's 2% as a decimal), n = 1,
t = 1 for the first answer, t = 2 for the second answer (1 year, then for 2 years)
Plug the known values in to solve...
For 1 year...
A = 5,500(1 + 0.02/1)^(1*1)
A = 5,500(1.02)^1
A = 5,610
For 2 years...
A = 5,500(1 + 0.02/1)^(1*2)
A = 5,500(1.02)²
A = 5,722.20

Answer:
a = -3 and b=5
Step-by-step explanation:
Given that 10 can be written as 2*5 or √2*√2*5, and √18 can be written as √(2*9) or √2*√9 or 3√2, you can write the fraction as:

it looks like an isosceles triangle, 2 equal side and 2 equal angles (F&E)
the sum of the interior angles in a triangle is 180°, and FH is 180°.
180 - 120 = 60° (angle G)

Gerald has three shirts (blue, white, and grey), four pairs of pants (black, light grey, dark grey, and blue), and three ties (orange, blue, and black). How many different outfits that include one shirt, one pair of pants, and one tie can Gerald make?
Answer:
36
Step-by-step explanation:
By the Fundamental Counting Principle, if there are x ways to choose one thing, y ways to choose another thing, and z ways to choose another thing, then there are x*y*z possible combinations of all of those things.
Here, there are 3 ways to choose a shift, 4 ways to choose a pair of pants, and 3 ways to choose a tie. Therefore, there are 3*4*3 = 36 different outfits that Gerald can make that include one shirt, pair of pants, and tie.

7*10 = 70
24*(21-10) = 264
264 + 70 = 334
Answer:
334 ft²
Step-by-step explanation:
split the polygon into two
Area of A = 21 ft × 7 ft = 147 ft²
Area of B = (21 ft - 10 ft) × (24 ft - 7 ft)
Area of B = 11 ft × 17 ft = 187 ft²
Area of polygon = sum of Areas of A and B
147 ft² + 187 ft² = 334 ft²

Ruby has a pulse rate of 73 beats per minute and a blood pressure of 121 over 85. If ruby’s blood pressure can be modelled by a sinusoidal function, find an equation of this sinusoid.
The blood pressure of Ruby is modelled by following sinusoidal equation: [tex]y = 103 +18\cdot \sin (146\pi\cdot t)[/tex].
How to model blood pressure by sinusoidal functionsA sinusoidal function is represented by following model:
[tex]y = 0.5\cdot (y_{min}+y_{max}) + 0.5\cdot (y_{max}-y_{min})\cdot \sin (2\pi\cdot f\cdot t)[/tex] (1)

The graph for Pool A shows the gallons of water filling the pool as a function of time. The graph for Pool B shows the rate of filling the pool as a function of time. Use the drop-down menus to complete the statements below about the two pools.
The graphs of pool A and pool B are illustrations of piece-wise functions
The rate of both pools from t1 to t2, t is 0.
How to determine the rates of the graphsFrom 0 to t1, the rates of the pools are:
Pool A = A/t1
Pool B = B/t1
Where A represents the gallons of water in the pool and B represents the rate at time t1
From t1 to t2, the rate of both pools is 0.

Two airplanes leave the airport. Plane A departs at a 44° angle from the runway, and plane B departs at a 40° angle from the runway. Which plane was farther away from the airport when it was 6 miles from the ground? Round the solutions to the nearest hundredth.
Group of answer choices
Plane A because it was 31.67 miles away
Plane A because it was 22.78 miles away
Plane B because it was 34.23 miles away
Plane B because it was 26.22 miles away
Answer: Answer:
Plane B was farthest away from the airport
Step-by-step explanation:
"This question requires you to visualize the run way as the horizontal distance to be covered, the height from the ground as the height gained by the plane after take of and the distance from the airport as the displacement due to the angle of take off.
In plane A
The take-off angle is 44° and the height gained is 22 ft.
Apply the relationship for sine of an angle;
Sine Ф°= opposite side length÷hypotenuse side length
The opposite side length is the height gained by plane which is 22 ft
The angle is 44° and the distance the plane will be away from the airport after take-off will be represented by the value of hypotenuse
Applying the formula
sin Ф=O/H where O=length of the side opposite to angle 44° and H is the hypotenuse
In plane B
Angle of take-off =40°, height of plane=22miles finding the hypotenuse
Solution
After take-off and reaching a height of 22 ft from the ground, plane A will be 31.67 miles from the airport
After take-off and reaching a height of 22 ft from the ground, plane B will be 34.23 miles away from the airport."

The inverse of G(x) is a function.
Answer:
False
Step-by-step explanation:
In order for the inverse of a relation to be a function, it must pass the horizontal line test. That is, a horizontal line cannot intersect the graph in more than one place. Here, the x-axis intersects the graph of G(x) in 3 places, so the inverse of G(x) is not a function.
angles of a quadrilateral are y,2y,3y+20 and 4y+30 . find each angle if the sum of the angles of a quadrilateral is 360°
Answer:
31° , 62° , 113° , 154°
Step-by-step explanation:
sum the 4 angles and equate to 360
y + 2y + 3y + 20 + 4y + 30 = 360 , that is
10y + 50 = 360 ( subtract 50 from both sides )
10y = 310 ( divide both sides by 10 )
y = 31
2y = 2(31) = 62
3y + 20 = 3(31) + 20 = 93 + 20 = 113
4y + 30 = 4(31) + 30 = 124 + 30 = 154
the 4 angles are 31° , 62° , 113° , 154°
