Answer: x=-2
Step-by-step explanation: First we can multiply 4 times anything in the parantheses to get rid of it.
(2x-6)+4(x-3)
(2x-6)+4x-12
Then we combine like terms.
(2x-6)+4x-12
6x-6-12
6x-18
Finally we divide both sides 6.
6x-18
6x/6-18/6
x=-2
The final answer is x=-2

The selling price of an item is $480. It is marked down by 10%, but this sale price is still marked up from the cost of $360. Find the markup from cost to sale price.
Answer:
72
Step-by-step explanation:
i just know it
If the selling price of an item is $480. It is marked down by 10%, but this sale price is still marked up from the cost of $360.Then 72 is the markup from cost to sale price
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
The selling price of an item is $480
It is marked down by 10%, but this sale price is still marked up from the cost of $360
We need to find 10% of 480
10/100=0.1
0.1×480=48
48 is the 10% of 480
Now subtract 48 from 480
480-48
432
Now subtract 360 from 432
432-360
72
Hence 72 is markup from cost to sale price

Which equation represents a line that is perpendicular to y=x?
A.
y=2x
B.
y=−x+6
C.
y=−2x
D.
y=x+1
Answer:
B
Step-by-step explanation:
The general equation of a straight line can be represented as;
y = mx + b
where m is slope
If two lines are perpendicular, the product of their slopes will be -1
So since the slope of the first line is 1, then the slope of the second line will be -1
Out of all the options, only have its slope as -1 and this y = -x + 6 and this is our answer

Answer:
a = p * q
b = p * s + q * r
c = r * s
Step-by-step explanation:
In the trinomial ax² + bx + c
a is the coefficient of x²
b is the coefficient of x
c is the numerical term
∵ The trinomial is ax² + bx + c
∵ Its factors are (px + r) and (qx + s)
∴ ax² + bx + c = (px + r)(qx + s)
∵ (px + r)(qx + s) = (px)(qx) + (px)(s) + r(qx) + (r)(s)
∴ (px + r)(qx + s) = pqx² + (psx + qrx) + rs
∴ ax² + bx + c = pqx² + (ps + qr)x + rs
→ By comparing the two sides
∵ ax² = pqx² ⇒ divide both sides by x²
∴ a = pq
∵ bx = (ps + qr)x ⇒ Divide both sides by x
∴ b = ps + qr
∴ c = rs
∴ a = p * q
∴ b = p * s + q * r
∴ c = r * s

Every ride at the country fair costs the same amount. The cost of one ride is $2.25. The fair entry fee is $6.50. Lupe paid the entrance fee and rode 7 rides. How much did Lupe pay in all?
Answer:
$22.25Step-by-step explanation:
Step one:
given data
we are told that the cost of one ride is $2.25
the entry fee= $6.5
the linear function for the situation is represented by the equation of line
y=mx+c
Step two:
let x be the number of ride
given that x=7
substituting we have
y=2.25(7)+6.5
y=15.75+6.5
y=22.25
In all Lupe we have to pay $22.25

Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.

Please help! what is an equation of a parabola with x-intercepts at (2,0) and (-7,0) and which passes through the point (1,32)?
Answer:
[tex]f(x)=-4(x-2)(x+7)[/tex]
Or, in standard form:
[tex]f(x)=-4x^2-20x+56[/tex]
Step-by-step explanation:
We can use the factored form of a quadratic equation:
[tex]f(x)=a(x-p)(x-q)[/tex]
Where a is the leading coefficient and p and q are the zeros of the quadratic.
We know that the x-intercepts are at (2, 0) and (-7, 0).
So, let's substitute 2 for p and -7 for q. This yields:
[tex]f(x)=a(x-2)(x+7)[/tex]
Now, we need to determine a.
We know that it passes through the point (1, 32). In other words, if we substitute 1 for x, we should get 32 for f(x). Therefore:
[tex]32=a(1-2)(1+7)[/tex]
We can now solve for a. First, compute:
[tex]32=a(-1)(8)[/tex]
Multiply:
[tex]32=-8a[/tex]
Divide both sides by -8:
[tex]a=-4[/tex]
So, the value of a is -4.
Therefore, our entire equation is:
[tex]f(x)=-4(x-2)(x+7)[/tex]
Notes:
We can expand this into standard form:
[tex]f(x)=-4(x-2)(x+7) \\ f(x)=-4(x^2+5x-14) \\ f(x)=-4x^2-20x+56[/tex]
-6x+9-4x=14 The value for x
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex] - 6x + 9 - 4x = 14[/tex]
[tex] - 6x - 4x + 9 = 14[/tex]
Collect like terms
[tex]( - 6 - 4)x + 9 = 14[/tex]
[tex] - 10x + 9 = 14[/tex]
Subtract sides 9
[tex] - 10x + 9 - 9 = 14 - 9[/tex]
[tex] - 10x = 14 - 4 - 5[/tex]
[tex] - 10x = 10 - 5[/tex]
[tex] - 10x = 5[/tex]
Divide sides by - 10
[tex] \frac{ - 10x}{ - 10} = \frac{5}{ - 10} \\ [/tex]
[tex]x = - \frac{5}{10} \\ [/tex]
[tex]x = - \frac{5}{5 \times 2} \\ [/tex]
[tex]x = - \frac{1}{2} \\ [/tex]

If in the 1980's about 60 million families had Tv's in their homes and in 2015 there was almost 100 million families that had Tv's in their home how many more Tv's were there in 2015?
Answer: 40 million
Step-by-step explanation:
Number of families that had TVs in their home in 1980s = 60 million
Number of families that had TVs in their home in 2015 = 100 million
To calculate the increase in TVs that were there in 2015, we subtract the number of families that had TVs in their home in 1980s which was 60 million from the number of families that had TVs in their home in 2015 which was 100 million. This can be expressed as:
= 100 million - 60 million
= 40 million
Answer:
it would be 1950 and 45 million

(45)×(512) = ___ / 5×12
Answer:
x=1382400
this should be right
Answer:
1382400
Step-by-step explanation:
Well, we can first find that 5x12 is 60 so if you substitute it, it would be:
45x512 = ___ / 60
We can also substitute ___ as x:
45x512 = x/60
45x512 is 23040 so, 23040 = x/60.
Bring sixty to the other side and multiply
x= 23040 x 60 = 1382400

The volume V of gas varies inversely to the pressure P. The volume of a gas is 200 cm3 under pressure of 32 kg/cm2. What will be its volume under pressure of 40 kg/cm2?
Answer:
V = 160 cm³ when P = 40 kg/cm²
Step-by-step explanation:
V = k / P
Where,
V = volume
P = pressure
k = constant of proportionality
The volume of a gas is 200 cm3 under pressure of 32 kg/cm2
V = k / P
200 = k / 32
Cross product
200 × 32 = k
6,400 = k
k = 6,400
What will be its volume under pressure of 40 kg/cm2?
V = k / P
= 6,400 / 40
= 160
V = 160 cm³
