It's a quadratic equation which simplifies to x²+2x-8
Now if you want to "solve" it then you must be a little more particular with your question because you can do many things with a quadratic equation, you can:
1. Factorise it
2. find the zeros
3. graph it
4. describe the nature of its roots,etc
but let me help you factorise it

-3x + 4 > 25 explain the steps needed to solve the inequality.
Answer:
x < - 7
Step-by-step explanation:
Given
- 3x + 4 > 25 ( subtract 4 from both sides )
- 3x > 21
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x < - 7
What is the equation of the following are you sure to scroll down first to see all answer options
Answer:
Y=-3x+0 or Y=-3x
Step-by-step explanation:
Y=mx+b
m=slope
b=y-intercept (where the line crosses the y axis)
The line crosses the Y axis at (0,0), so:
Y=mx+0 or
Y=mx
Slope:
Rise/run= Change in y/Change is x= 9/-3=-3
So:
Y=-3x+0 or
Y=-3x
Answer: 3x + y = 0
Step-by-step explanation: Remember that slope is represented by
rise over run from one point to the next on our graph.
To get from the point (0, 0) to (3, -9), we go down -9 units
so our rise is -9 and we run 3 units so our run is 3.
Our slope therefore or m = -9/3 or -3.
Our y-intercept is represented by the point where this line
crosses the y-axis which in this case is up 0 units.
So our y-intercept or b = 0.
Since we have the slope and y-intercept of our line,
we can now write its equation in y = mx + b form.
Since m = -3 and b = 0, that gives us y =-3x + 0.
Now we convert this equation to standard form.
Just add 3x to both sides to get 3x + y = 0.
So the equation of this lie is 3x + y = 0.

Lara makes birdseed by mixing peanuts and sunflower seeds in a 2:3 ratio. The peanuts costs 3p per 10g and the sunflower seeds cost 9p per 10g. Lara sells the birdseed £1 per 100g portion.
How much profit does Lara make on each portion? Give your answer in pence.
Step by step explanation plssss tqsm.
Answer:
Lara will do a profit of 34 pence by 100 grams of birdseed.
Step-by-step explanation:
The given ratio means that there are 2 grams of peanuts and 3 grams of sunflower per each 5 grams of birdseed. Now, we obtain the amount required of peanuts and sunflower for 100 grams of birdseed by simple rule of three:
Peanuts
[tex]x = \frac{100\,g}{5\,g}\times 2\,g[/tex]
[tex]x = 40\,g[/tex]
Sunflower
[tex]y = \frac{100\,g}{5\,g}\times 3\,g[/tex]
[tex]y = 60\,g[/tex]
If we know that 10 grams of sunflower cost 9 pence and 10 grams of sunflower cost 3 pence, then the total cost of production of 100 grams portion:
[tex]C = \left(\frac{0.03\,GBP}{10\,g} \right)\cdot (40\,g)+\left(\frac{0.09\,GBP}{10\,g} \right)\cdot (60\,g)[/tex]
[tex]C = 0.66\,GBP[/tex]
And the profit done by Lara is:
[tex]\Delta C = 1\,GBP - 0.66\,GBP[/tex]
[tex]\Delta C = 0.34\,GBP[/tex]
Lara will do a profit of 34 pence by 100 grams of birdseed.

Hosea borrowed $20,000 to buy a new speed boat. The interest rate on his loan is 5%. If he plans to pay the loan back in three years, how much interest will he pay? What will be the total cost that he will owe including interest?
Answer:
a. Interest amount is $3,000.
b. Total cost is $23,000.
Step-by-step explanation:
a. How much interest will he pay
This can be calculated as follows:
Interest amount = Principal loan Amount * Interest rate * Number of years ........ (1)
Where;
Principal loan Amount = $20,000
Interest rate = 5%
Number of years = 3
Substituting the values into equation (1), we have:
Interest amount = $20,000 * 5% * 3 = $3,000
b. What will be the total cost that he will owe including interest?
Total cost = Principal loan Amount + Interest amount = $20,000 + $3,000 = $23,000

Hunter invested $750 in an account paying an interest rate of 6\tfrac{5}{8}6 8 5 % compounded continuously. London invested $750 in an account paying an interest rate of 6\tfrac{1}{2}6 2 1 % compounded daily. After 18 years, how much more money would Hunter have in his account than London, to the nearest dollar?
Answer: $ 55
Step-by-step explanation:
When interest is compounded continuously, the final amount will be
[tex]A=Pe^{rt}[/tex]
When interest is compounded daily, the final amount will be
[tex]A=P(1+\dfrac{r}{365})^{365t}[/tex]
, where P= Principal , r = rate of interest , t = time
For Hunter , P= $750, r = [tex]6\dfrac{5}{8}\%=\dfrac{53}{8}\%=\dfrac{53}{800}=0.06625[/tex]
t = 18 years
[tex]A=750e^{0.06625(18)}=\$2471.48[/tex]
For London , P= $750, r = [tex]6\dfrac{1}{2}\%=\dfrac{13}{2}\%=\neq \dfrac{13}{200}=0.065[/tex]
t = 18 years
[tex]A=750(1+\dfrac{0.065}{365})^{18(365)}=\$2416.24[/tex]
Difference = $ 2471.48 - $ 2416.24 =$ 55.24≈$ 55
Hence, Hunter would have $ 55 more than London in his account .

In the trapezoid below, x = [ ? ].
2x+6
I
5x=20
4r+2
Answer:
x = 12
Step-by-step explanation:
To get the value of x, we use the mid-segment theorem of trapezoid
The theorem is that the mid-segment is half the sum of the other two segments
We have this as
;
5x - 20 = 1/2(2x + 6 + 4x + 2)
2(5x-20) = 6x + 8
5x -20 = 3x + 4
5x -3x = 4 + 20
2x = 24
x = 24/2
x = 12

solve the linear equation 1/5(10x-20)=x-3
Answer:
x=1
Step-by-step explanation:
1/5(10x-20)=x-3
2x-4=x-3
2x-x=4-3
x=1
Answer:
The value of x is 1 after solving the linear equation.
Step-by-step explanation:
Given equation is:
[tex]\frac{1}{5}(10x-20)=x-3[/tex]
We will solve the equation by simplifying first.
[tex]\frac{1}{5}*10x-\frac{1}{5}*{20}=x-3\\2x-4=x-3[/tex]
Now, we will subtract x from both sides of the equation,
2x-x-4 = x-x-3
x-4 = -3
Next, we will add 4 on the both sides of the equation,
x-4+4 = -3+4
x = 1
Hence,
The value of x is 1 after solving the linear equation.

Answer:
A. 3.7, because |3.7| = 3.7
Step-by-step explanation:
What the question is referring her by magnitude is units away from 0. 3.7 is 3.7 units away from 0, which is the same thing as the absolute value of 3.7. And since absolute value is always positive, C is already out. D is also out as the value doesn't change. B's reason contradicts the answer, so it is also wrong. This leaves A (3.7, because |3.7| = 3.7) as our answer.

Step-by-step explanation:
3. Problema 2: Suponga que un fabricante de radios tiene la función de costo total C (x) = 43x + 1850 dólares y la función de ingreso R (x) = 80x dólares. Donde "x" es el número de radios fabricados y vendidos. Halle:
Responder:
$ 11,137
Explicación paso a paso:
Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.
Dado
Función de costo C (x) = 43x + 1850
Función de ingresos R (x) = 80x
Obtener la función de ganancias
P (x) = R (x) - C (x)
P (x) = 80x - (43x + 1850)
P (x) = 80x - 43x - 1850
P (x) = 37x - 1850
Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:
P (351) = 37 (351) - 1850
P (351) = 12,987-1850
P (351) = 11,137
Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137
