Answer: x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2
Step-by-step explanation:
2x^2 = 4 + 6x
divide both sides by 2
x^2 = 2 + 3x
move expression to the left
x^2 - 2 - 3x = 0
reorder the terms
x^2 - 3x - 2 = 0
use the quadratic formula
x = - (-3) +- sqrt (-3)^2 - 4 x (-2) / 2 x 1
calculate
x = 3 +- sqrt 17 / 2
answer
x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2

Explanation:
Anything is categorized by how it matches with the definition of the category.
A composite number is a product of primes. A prime number is divisible only by itself and 1.
If a number has more than one prime factor (even if that is just multiple instances of the same prime factor), it goes into the composite number category. If its only prime factor is itself, it goes into the prime number category.

2/3 divide 1/8 using kcf
Answer:
2/3 divdied by 1/8 is 5 1/3
Step-by-step explanation:
You first keep the 2/3, change the operation to multiplication, then flip the 1/8 to 8/1, then multiply across to get 16/3. After that, simplify to get 5 1/3
Find the degree of the monomial -1.57k^2
Answer:
2
Step-by-step explanation:
Degree of the monomial is the highest power in the monomial.
Highest power in the monomial - 1.57k^2 is 2.
So, the degree of the monomial - 1.57k^2 is 2.
Yesterday you borrowed $60 from your brother. Every day that you don't pay it back, you owe $2.00 more. So today, day one, you owe him $62.00, on day two you will owe him $64.00, on day three you will owe him $66.00, etc. If you still haven't paid him back, how much will you owe him on day 25?
Answer:
110 dollars.
Step-by-step explanation:
Since every day you owe him 2 dollars more, and its been 25 days, 25 x 2 is 50.
You originally owed him 60, and 50 dollars in late fees, so 60 + 50 = 110.
You owe him 110 dollars.

Answer:
a. 19
Step-by-step explanation:
5/6x-1/5x=19
5/6(30)-1/5(30)=19
25-6=19
19=19
?/30(30)=19
19/30(30)=19
19=19
I'm not sure if this is exactly what you're looking for, but 19=19 if you plug in 19 for the box (and x=30 because of the first section, I'm guessing)
Question 6(Multiple Choice Worth 1 points)

What is the initial value of the equation shown?
y = -4x - 3
O-4
O-3
03
04
9514 1404 393
Answer:
(b) -3
Step-by-step explanation:
The "initial value" is the constant in the equation. It is the value that remains when the x-term is removed. It is the result of evaluating the equation when x=0.
y = -4(0) -3 . . . . substitute x=0
y = 0 -3
y = -3 . . . . the "initial value"

Answer:
1a: $84; 1b: 30,000A +15,000B; 1c: 37,000A +18,500B
2: 4,000 composite units
Step-by-step explanation:
We assume your "composite unit" consists of the smallest set of units in the ratio in which they are sold.
1)A "composite unit" is 1B +2A. The contribution margins are the difference between the selling price and the variable cost per unit:
A: 72 -40 = 32
B: 48 -28 = 20
composite unit: 2A+B = 2(32) +20 = 84
(a) The contribution margin per composite unit is $84.
__
(b) The break-even point is the number of composite units that have a total contribution margin equal to the total fixed costs:
84n = 1260000
n = 1260000/84 = 15000
30,000 units of A and 15,000 units of B must be sold to break even.
__
(c) The additional number of composite units required to achieve pre-tax income of 294000 is ...
294,000/84 = 3500
37,000 units of A and 18,500 units of B must be sold for a pretax income of $294,000.
__
2)Contribution margins per unit are ...
H: 6 -4 = 2
C: 8 -6 = 2
I: 10 -7 = 3
A composite unit is 3H +2C +I, so the contribution margin per composite unit is ...
3(2) +2(2) +1(3) = 6 +4 +3 = 13 . . . dollars
The break-even point is 52,000/13 = 4,000 composite units

The sum of the interior angles of a triangle is 180 degrees. Therefore, we can add up angles E, F and G, set the sum equal to 180, and solve.
(8x - 16) + (x + 8) + (2x - 10) = 180
11x - 18 = 180
11x = 198
x = 18

Anna spends one- fifth of her monthly paycheck on books. If she spends $50 per month,what is her monthly paycheck
Answer:
$250
Step-by-step explanation:
Reverse division is multiplication. So one fifth of 50 is ?/5=50. Now reverse this to 50*5=?. This should come out to 250, because you can leave off the zero, and do 5*5, which equals 25, and add the zero back in you get 250. So your answer is $250.
Use function notation to write the equation of the line. PLEASE ANSWER ASAP
Answer:
option 2: f(x) = 4x + 4
Step-by-step explanation:
Graph is positive, so with this you should already know that options: 1, 3, 4 are incorrect since those are negative.
However, let's break it down more.
To write the function for a line, you use y = mx+b
m stands for the rise/run
b stands for the y-intercept
Rise over run is 4/1, or just 4
With this we know that option 3 is not correct, yet again
Our y intercept is 4
With this we know that option 1 is not correct, yet again
This just leaves option 2 and 4 with the correct slope and y-intercept, yet as we said before this is a positive slop, so again, 4 is incorrect

Four fifth of a number 'm' is 4 more than three-fourth of the same number. Find the number.
Answer:
Let the number be x. Then, 4/5x - 3/4x = 4. Hence, The required number is 80.
Step-by-step explanation:
Let the number be x.
According to the question, lets form an equation
5
4x −4
3x +4
⇒ 5 4x − 4
3x =4
20
16x − 15x =4
⇒ 20x =4
⇒ x=4×20
⇒x=80
∴ The number is x=80.

O f(x) = 1/2x + 4
Of(x) = 1/2x + 6
O f(x) = 1/2x-10
Of(x) = 1/2x-12
Answer:
y = 1/2x + 6
Step-by-step explanation:
y - 8 = 1/2 (x - 4)
y - 8 = 1/2x - 2
y = 1/2x -2 + 6

Here is a diagram of triangle DEF.
Find the measures of angles q, r, and s.
(PLEASE help ASAP I will give brainliest!)
Answer:
q= 100
r= 135
s= 125
Step-by-step explanation:
These are the angles
The measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.
What are Alternate Interior Angles?Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.
These are the angles
⇒ q = 180 - 80 = 100
⇒ r = 180 - 45= 135
⇒ s = 180 - (180 - 80 - 45) = 125
So the sum of the measures of angles q, r, and s
⇒ q + r + s = 100 + 135 + 125 = 360°
Thus, the measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.
