Answer:
[tex]x = 2[/tex]
Step-by-step explanation:
First simplify the equation.
[tex]\frac{7}{9}x -\frac{4}{9} =\frac{1}{4} +\frac{5}{12}[/tex] [tex]\frac{3}{9}x= \frac{3}{12} +\frac{5}{12}[/tex] [tex]\frac{3}{9}x=\frac{8}{12}[/tex] [tex]\frac{1}{3}x=\frac{2}{3}[/tex]Now multiply both sides by 3.
[tex]x = 2[/tex]
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]

y=x squared - 4x
Answers
This is one way of doing it.
We want to get the function into vertex form.
y = x2 - 4x + 2 Subtract 2 from both sides.
y - 2 = x2 - 4x Add (-4/2)2 , or 4, to both sides.
y - 2 + 4 = x2 - 4x + 4 Now that the right hand side is a perfect square trinomial, factor it.
y + 2 = (x - 2)(x - 2)
y + 2 = (x - 2)2 Subtract 2 from both sides.
y = (x - 2)2 - 2
When the equation is in this form, we can see that this is the graph of y = x2 shifted to the right 2 units and shifted down 2 units. The vertex is at (2, -2). So plot the first point at (2, -2) and go up just like a basic parabola from there. :)

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

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]

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.
