Which expression correctly represents “three less than the product of a number and two, increased by five”?
Answers
Answer:
Let x represents the number.
Given the statement: "Three less than the product of a number and two, increased by five".
"Product" means multiply
"Product of a number and two" translated to
"Three less than the product of a number and two" translated to 2x - 3
Increased by 5 means +5
then;
the given statement becomes;
Therefore, the expression that represents "three less than the product of a number and two, increased by five" is

You have the information given above. Let's start with just ad = 11.6 for now. since these are variables, it can also be understood be understood as a times d= 11.6.
Knowing this, we can figure out that d = 11.6/a, when you divide both sides by a.
You now have d, so plug (11.6/a) into cd=6.7. You have to do the same thing you did last time, except this time you are aiming to get c by itself. So, multiply both sides by a/11.6 and you get c = (6.7a)/ 11.6.
Guess what, you know c now! so you put (6.7a)/11.6 in for c in the equation given to you earlier, bc =8.3. The math gets a bit messy here, but you basically solve for b here, which, when you crunch the numbers down, ends up being ~14.3705 divided by a. You are looking for ab, so just multiply both sides by a, and round to the nearest tenth so that you have ab= 14.4

Would take the terms in reducing powers of x, and increasing powers of 2.
1st term = ¹⁰C₀ x¹⁰(2)⁰ = x¹⁰
Second term = ¹⁰C₁ x¹⁰⁻¹(2)¹ = ¹⁰C₁ x⁹(2)¹
Third term = ¹⁰C₂ x¹⁰⁻²(2)² = ¹⁰C₂ x⁸(2)²
Fourth term = ¹⁰C₃ x¹⁰⁻³(2)³ = ¹⁰C₃ x⁷(2)³
So we shall now simplify the fourth term which is = ¹⁰C₃ x⁷(2)³
ⁿCr = n! /( r!(n -r)! )
¹⁰C₃ = 10! /( 3!(10 -3)! ) = 10! / (3!*7!) = (10 *9 * 8* 7!) / (3!*7!)
= 10*9*8 / 3! = (10*9*8) / (3*2*1) = 120
4th term = ¹⁰C₃ x⁷(2)³ = 120 *x⁷*(2)³ = 120*2³*x⁷
= 120*8x⁷
= 960x⁷
So the fourth term in reducing powers of x = 960x⁷
I hope this helped.

Step-by-step explanation:
You can easily identify intercept points by solving for one variable when the other is zero.
x-intercept (y=0)
4x = 12
x = 12/4 = 3
y-intercept (x=0)
-3y = 12
y = 12/-3 = -4
So, the coordinate pairs of these points are ...
(3, 0) and (0, -4)
__
If you solve for y, you get ...
-3y = 12 -4x
y = (4/3)x -4 . . . . . divide by -3
This suggests that x being a multiple of 3 will be useful for finding integer values of y.
We already have points for x=0 and x=3. We can add points for x=6 and x=-3.
y = 4/3(6) -4 = 4
y = 4/3(-3) -4 = -8
So, the additional points are ...
(6, 4) and (-3, -8)
Answer:X=3
y= -4
Step-by-step explanation:
If we're solving for x or y, then the intercept we're not solving for is equal to zero. Solving for y means x=0, solving for x means y=0.
so solving for x, 4x=12--> x=3, since y=0 in this scenario.
Solving for y, x=0, so -3y=12--> y=(-4)

Step-by-step explanation:
The mirror is set away from the flagpole on the same scale set away from her.
The distance she stand's away from the mirror is 1/4 of the length of the distance between the mirror and the flag pole because she's 1/4 of the flagpole's size.
This means her size x4 is the size for the flag pole. This checks out because 12x4=48
So to find the height we must do 5x4
5x4=20

There are 5π/3 radians in 300 degrees.
To convert degrees to radians, we can use the formula:
Radians = Degrees x (π / 180)
Given that we want to convert 300 degrees to radians, we can plug this value into the formula:
Radians = 300 x (π / 180)
Simplifying this expression, we get:
Radians = 5π/3
Therefore, there are 5π/3 radians in 300 degrees.
