Ecuación:
• Soluciones:
Answers
Construyendo y resolviendo una ecuación, tenemos que el número puede ser 8 o -10.
El número es desconocido, así que lo llamaremos x. El cuadrado del número es [tex]x^2[/tex].El doble es [tex]2x[/tex], sumando al cuadrado, [tex]x^2 + 2x[/tex].Se resta 5, o sea, [tex]x^2 + 2x - 5[/tex].Obtiene 75, entonces: [tex]x^2 + 2x - 5 = 75[/tex].Para encontrar el número, tenemos que resolver una ecuación cuadrática, luego:
[tex]x^2 + 2x - 5 = 75[/tex]
[tex]x^2 + 2x - 80 = 0[/tex]
Ecuación cuadrática con [tex]a = 1, b = 2, c = -80[/tex]
[tex]\Delta = 2^2 - 4(1)(-80)[/tex]
[tex]x_{1} = \frac{-2 + \sqrt{324}}{2} = 8[/tex]
[tex]x_{2} = \frac{-2 - \sqrt{324}}{2} = -10[/tex]
El número puede ser 8 o -10.

Given : VU = 8 cm, let SV = n and SU = m
[tex] \tan(45) = \dfrac{8}{m} [/tex][tex]1 = \dfrac{8}{m} [/tex][tex]m = 8 \: \: cm[/tex]so, SU = 8 cm

I hope it helps you. Please choose my answer as the BRAINLIEST.
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
[tex]\cfrac{7}{9}\:x-\cfrac{4}{9}\:x=\cfrac{1}{4}+\cfrac{5}{12}[/tex]
First, combine [tex]\frac{7}{9} x[/tex] and [tex]-\frac{4}{9} x[/tex] = [tex]\frac{1}{3} x[/tex]
[tex]\cfrac{1}{3}\: x=\cfrac{1}{4} +\cfrac{5}{12}[/tex]
LCM of 4 and 12 is 12, Convert 1/4 and 5/12 to fraction with denominator 12:
[tex]\cfrac{1}{3}\: x=\cfrac{3}{12} +\cfrac{5}{12}[/tex]
Since 3/12 and 5/12 have the same denominator, let's add numerators:
[tex]\cfrac{1}{3}\:x=\cfrac{3+5}{12}[/tex]
[tex]\cfrac{1}{3}\:x=\cfrac{8}{12}[/tex]
Reduce the fraction 8/12 to lowest term by extracting and canceling out 4,
[tex]\cfrac{1}{3} \:x=\cfrac{2}{3}[/tex]
Multiply both sides by 3, reciprocal of 1/3:
[tex]x=\cfrac{2}{3} \times 3[/tex]
Cancel out 3 and 3:
[tex]x=2[/tex]

Subtract 10x2 – 10x + 2 from - 8x2 + 7x – 7.
Answers
Answer:
18x^2 - 17x +9
Step-by-step explanation:
Original equations:
10x^2 - 10x + 2
-8x^2 +7x - 7
Calculations:
10x^2 - (-8x^2) = 18x^2
(-10x) - 7x = -17x
2 - (-7) = 9
Together, they make: 18x^2 - 17x + 9

Since the lines BO and CO are bisectors, it means that the angles are halved fo take half of angle B plus half of angle C and add them together = 65 and then do 180-65=115 so the angle BOC is 115°

28) B
29) 1/6
30) 21 degrees was the high temperature
Step-by-step explanation:
- I can't see the clock well, but I'll guess its 10:20. 30 minutes after would be 10:50.
- There are 6 common factors of 50 and 100.
1,2,5,10,50,25
- 12/4 is 3.
- A shopper purchased 2 items, each were $3.49 (That is all the info we need to create an equation to solve/estimate the cost of the purchase) We multiply 2 by $3.49 to get the total cost. Or in other words multiply the items by the price to get the total
- We multiply 1/3 by x amount of batches. So in this case we have 2. It becomes 1/3 times 2 = 1/6
- The low temperature is 8 degrees because each line represents a difference of 2 and 10 - 2 = 8. Now to calculate the high temperature, you add 13 to 8 = 21.

for,
q(x) = 1/2x² + 7
q(8) = 1/2(8²) + 7
q(8) = 39.
Answer:
q(8) = 39
Step-by-step explanation:
To solve this question, you need to plug in (substitute) 8 instead of x:
q(8) = [1/2(8)²] + 7
= (1/2 × 64) + 7
= 32 + 7
= 39
∴ q(8) = 39
