Answer:
x²-3x-10=0
x²-5x+2x-10=0
x(x-5)+2(x-5)=0
(x-5)(x+2)=0
either
x-5=0
x=5
or
x+2=0
x=-2
Answer:
x = 5 and -2
Step-by-step explanation:
i hate the factorization method
The factorization method is that there are factors of c that add up to b
so -2 * 5 = -10, but so does -5 * 2, so um, i kinda forgot how to do this, but the answer is 5 and -2, I got it using m+/- √(m^2 - p)
Megan owns a clothing boutique. The table below represents the profit made, in dollars, every year since 2010, where x represents the number of years since 2010.

Answer:
4/5x+2/5 = y
Step-by-step explanation:
(-3, -2) & (2,2) - given points
1. Find Slope
2-(-2) / 2-(-3) = 4/5
m=4/5
2. plug in points to find b
4/5(x)+b=y : mx+b=y (slope intercept form)
4/5(2)+b=2
8/5+b=2
2 - 8/5 = b
10/5 - 8/5 = b
b=2/5
Therefore: 4/5x + 2/5 = y

Is it possible to construct a triangle with side lengths of 3, 6, and 9 units? If not, explain why not
no; 9+6>3
O no: 6+39
no, 3+946
yes
Answer:
no: 6+3 = 9
Step-by-step explanation:
In order to construct a triangle with given side lengths, sum of any two side length must be greater than the third side length.
Here we can see that:
6 + 3 = 9, which is defying the required condition.
Hence, it is not possible to construct a triangle with side lengths 3, 6, and 9 units.
A fire ranger on a 150-ft-tall tower spots a fire at a 30° angle of depression. How
many feet away from the tower is the fire to the nearest tenth?
Answer:
259.8ft
Step-by-step explanation:
The distance from the tower to the fire to the nearest tenth is 260 feet.
Let the adjacent side be a.Given the following data:
Angle of depression = 30°.Opposite side = 150 feet.To determine how far away (in feet) from the tower is the fire to the nearest tenth:
How to apply trigonometric function.In order to solve this exercise, we would form a mental image of the scenario being described. The height of the tower is the opposite side while the distance from the tower to the fire is the adjacent side.
Next, we would apply the Tan trigonometric function:
[tex]Tan \theta = \frac{Opp}{Adj} \\\\Tan 30=\frac{150}{a} \\\\a=\frac{150}{Tan 30} \\\\a=\frac{150}{0.5774}[/tex]
a = 259.79 ≈ 260 feet.

Por una calculadora y un cuaderno habríamos pagado, hace tres días, 10,80 €. El precio de la calcula-dora ha aumentado un 8%, y el cuaderno tiene una rebaja del 10%. Con estas variaciones, los dos artículos nos cuestan 11,34 €. ¿Cuánto costaba cada uno de los artículos hace tres días?
Answer:
La calculadora y el cuaderno costaba 9 y 1,8 euros hace tres días.
Step-by-step explanation:
A partir del enunciado podemos construir el sistema de ecuaciones lineales:
Hace tres días:
[tex]x+y = 10.80[/tex] (1)
Actualmente:
[tex]1.08\cdot x + 0.9\cdot y = 11.34[/tex] (2)
Donde:
[tex]x[/tex] - Precio de la calculadora.
[tex]y[/tex] - Precio del cuaderno.
Por métodos algebraicos, tenemos que el sistema de ecuaciones tiene la siguiente solución:

On a math test, Rosie answered 36 questions correctly, which was 72%. how many questions were on the test?
Answer:
50
Step-by-step explanation:
What I did first is I converted 72% into a decimal (I work better with decimals), giving me 0.72. Then I solved the equation 36/0.72=x.
x = 50
Answer:
50 questionsStep-by-step explanation:
Let the number of questions be x.
We have:
72% of x is 36.Build an equation and solve for x:
0.72x = 36x = 36/0.72x = 50Parker and Eugene sold tickets for the school play.They each need to sell 35 tickets To receive a prize. On day one sold 23 tickets on day two sold 25 tickets and on day three the sold 35 tickets if they want to equally share the number of tickets between them how many ticket sales will each boy have
Answer: 41.5
Step-by-step explanation:
Number of tickets sold on day one = 23
Number of tickets sold on day two = 25
Number of tickets sold on day three = 35
Total tickets sold = 23 + 25 + 35 = 83
Since they want to share it equally, each boy will have:
= 83/2
= 41.5

1. The cost of attending college has been rising at an average increase of 7% for the past ten
years. How much will a college that now costs $10,368 for room, board, tuition and fees cost
two years from now?
Answer: $11,870.32
Step-by-step explanation:
Use a compound interest formula for this as it shows what happens when when something increases at a certain rate per period.
= Amount * ( 1 + rate) ^ no. of periods
= 10,368 * ( 1 + 7%) ²
= 10,368 * 1.1449
= $11,870.3232
= $11,870.32
what is the ordered pair solution for y>= 1/3x+4
Answer:
Step-by-step explanation:
y > (1/3)x + 4 has an infinite number of solutions. Draw a dashed line representing y = (1/3)x + 4 and then pick points at random on either side of this line. For example, pick (1, 6). Substitute 1 for x in y > (1/3)x + 4 and 6 for y. Is the resulting inequality true? Is 6 > (1/3)(1) + 4 true? YES. So we know that (1, 6) is a solution of y > (1/3)x + 4. Because (1, 6) lies ABOVE the line y = (1/3)x + 4, we can conclude that all points abovve this line are solutions.

#2 A triangle has a height three times its base. The area of a triangle is 73.5
square centimeters. What is the possible value of x for this real world
shape? (enter only a numerical answer. Do not put x=)
Answer: See explanation
Step-by-step explanation:
Let the base be represented by x.
Therefore, the height will be = 3 × x = 3x
Since Area of a triangle = 1/2 × base × height
1/2 × x × 3x = 73.5
3x²/2 = 73.5
3x² = 73.5 × 2
3x² = 147
x² = 147/3
x² = 49
x = ✓49
x = 7
Base = 7cm
Height = 3 × 7 = 21cm

Supplementary means the angels add up to 180 degrees. So 95 + ? = 180. The ? is equal to 85, but how do you get it. Well we know 5x means to multiply a # by 5. So 17 x 5 = 85. So x = 17. Hope this helps!
Answer:
17
Step-by-step explanation:
5 x 17 = 85 right?
95 + 85 = 180.

Answer:
sorry i forgoti would just look it up it might be right
Step-by-step explanation:
my last name is henry
Answer:
No solution
5 stars plz!
Step-by-step explanation:
describe y in terms of x, so using the equation 2x+y=5 we can determine:
5-2x=y
now replace y with 5-2x in the other equation
5-2x=-2x+5
take 5 from each side
-2x=-2x
uh-oh... no solution here
(I used the other one to define y and skipped to the part where I had one equation)
2x-2x+5=5
so simplify
5=5
