Answer:
x = xStep-by-step explanation:
The first step here is to use the distributive property to make the first equation back into a polynomial.
The way we do this is by multiplying each term on the inside of the parentheses by the -2 on the outside.
-2 x x = -2x
-2 x 3 = -6
So, our new equation reads: -2x - 6
-2x - 6 = -2x + 3 - 9
Our next step is to subtract the 9 from 3.
-2x - 6 = -2x - 6
We add 6 to each side
-2x = -2x
x = x
0 = 0

(8x – 23)
(6x + 11)°
M
L
HELPPP
Answers
Answer:
Step-by-step explanation:
J and K are equal
8x - 23 = 6x + 11 Add 23 to both sides
8x = 6x + 11 + 23 Combine the right
8x = 6x + 34 Subtract 6x from both sides
8x - 6x = 34 Combine the left
2x = 34 Divide by 2
x = 34/2
x = 17
=================================
M and L are both supplementary to J and K respectively.
J = 8x - 23
J = 8*17 - 23
J = 136-23
J = 113
K = 113
===================================
M + 113 = 180
M = 180 - 113
M = 67
L = 67
Billy's Bagels sells bagels and sandwiches. The profit on every bagel is $2 and the profit on every sandwich is $3. Billy made a profit of $1,560 last week.
a. Write an equation in a standard form that represents Billy's profits last week, where x is the number of bagels sold and y is the number of sandwiches sold.
b. Change the equation for Billy's profit to slope-intercept form.
c. Write the equation in function notation. HELP!!
Answers
Answer:
a. 2x + 3y = 1560
b. y = -2x/3 + 520
c. f(x) = -2x/3 + 520
Step-by-step explanation:
a. We are told that the profit on each Bagel is $2 for x bagels and $3 for each sandwich is $3
for a total of y sandwiches
So we have;
2x + 3y = 1560
b. Slope intercept form is generally
y = mx + b
So we have
3y = -2x + 1560
y = -2x/3 + 520
c. In function notation;
f(x) = -2x/3 + 520

By Pythagoras Theorem:
[tex] {y}^{2} = {12}^{2} + {x}^{2} \\ \\ {y}^{2} = {12}^{2} + {36}^{2} \\ \\ {y}^{2} = 144 + 1296 \\ \\ {y}^{2} = 1440 \\ \\ y = \sqrt{1440} \\ \\ y = 37.95[/tex]

Mackenzie built the small lego set it cost $5.49 Caleb built the large lego set how much do you think the large lego set cost
Answers
Answer:
Since there is no available data for the Lego set, it is safe to assume that the cost would be definitely higher than the small Lego set built by Mackenzie. For example, if the dimension of the small Lego set is 50 X 30 X 6 (length X breadth X height all in cm ) which cost Mackenzie $5.49.
On the other-hand, let assume that, the large Lego set built by Caleb is twice that of Mackenzie Lego set (that is 100 X 60 X 12 ), it could be found that, the cost for the large Lego set would cost minimum of $10.98

one factor of 8x^3+1 is 2x+1 The other factor is?
Answers
So that you have 2^3*x^3+1
Multiply the terms with equal exponents by multiply the bases (1 is basically the same as 1^3)
So that it becomes (2x)^3+1^3
Then, using a^3+b^3 equals (a+b)(a^2-2ab+b^2), factor the expression so that it becomes
(2x+1)((2x)^2-2x+1^2)
Expand the second bracket
So the two factors are (2x+1) and (4x^2-2x+1)
solve the system using substitution.

Answers
Answer:
x = 3
y= 12
Step-by-step explanation:
2x + 2y = 30
y - 4x = 0 /*2
2x + 2y = 30
2y - 8x = 0
-----------------
10x = 30
x = 3
y= 12
Answer:
( 3 , 12 )
Step-by-step explanation:
2x + 2y = 30 and y - 4x = 0 are two given equation
Name The equation
2x + 2y = 30 ...(1)
y - 4x = 0
y = 4x ...(2)
Now, Put the value of y in equation 1
2x + 2y = 30
2x + 2(4x) = 30
2x + 8x = 30
10x = 30
x = 30/10
x = 3
Now,
Put the value of x in equation 2
y = 4x
y = 4(3)
y = 12
Thus, The value of x is 3 and the value of y is 12
FOR VERIFICATION ONLY:-2x + 2y = 30 ...(1)
2(3) + 2(12) = 30
6 + 24 = 30
30 = 30
y = 4x ...(2)
12 = 4(3)
12 = 12
Hence, L.H.S = R.H.S

FG is the geometric mean of which two segments
Answers
Answer:
EG and GH
Step-by-step explanation:
FG is the geometric mean of EG and GH segments.
FG is the geometric mean of EG and GH by using the Right triangle altitude theorem.
Important information:
The given figure of a triangle EFH.Right triangle altitude theorem:According to the Right triangle altitude theorem, if an altitude is drawn on the hypotenuse of a right triangle, then the altitude of a right triangle is the geometric mean of the two segments of the hypotenuse.
From the given figure it is clear that,
Triangle EFH is a right triangle because angle F is a right angle.FG is the altitude on the hypotenuse.Two segments of the hypotenuse are EG and GH.Using the Right triangle altitude theorem, we get FG is the geometric mean of EG and GH.

Two customers went to the post office to buy postcards and large envelopes. Each postcard costs the same amount and each large envelope costs the same amount.
● The first customer paid $12 for 14 postcards and 5 large envelopes.
● The second customer paid $24.80 for 10 postcards and 15 large envelopes.
What was the cost in dollars of each large envelope?
1. $1.42
2. $1.15
3. $0.63
Answers
Answer:
The first one $1.42
Step-by-step explanation:
1.42x5=7.1 (cost of all envelopes)
12-7.1=4.9
4.9/14=0.35 (one postcard)
10 postcards= 3.5
1.42x15=21.3 (cost of all envelopes)
3.5+21.3=$24.80

Give your answer as a whole number of years.
Answers
Answer:i i think Brenda 10
Step-by-step explanation:
Age problems are the algebra word problem which deals with the ages of people in the present time.
Given information-
Abigail is 5 years older than Brenda.
Brenda is twice as old as Carly.
The total of their ages is less than 40.
Age problemsAge problems are the algebra word problem which deals with the ages of people in the present time.
Suppose Abigail is A, Brenda is B and Carly is C years old.
As Abigail is 5 years older than Brenda. Thus,
[tex] A=B+5[/tex] .... 1
As Brenda is twice as old as Carly. Thus,
[tex]C=\dfrac{B}{2} [/tex] ..... 2
As the total of their ages is less than 40.
[tex]A+B+C=40[/tex]
Keep the values of A and C from the equation 1 and 2 in the above equation,
[tex]\begin{aligned}\\ B+5+B+\dfrac{B}{2} &=40\\ 2B+\dfrac{B}{2} &=35\\ \dfrac{4B+B}{2}&=35\\ B&=\dfrac{35}{5} \times2\\ B&=14\\ \end[/tex]
Thus the Brenda is 14 year old. As the Abigail is 5 years older than Brenda. Thus the age of the Abigail is,
[tex]A=14+5\\ A=19[/tex]
Thus the Abigail is 19 year old.
