Answer:
Option (1) ; y = 7x
Step-by-step explanation:
(1) reads y = 7x, a line with slope 7, therefore the rate of change in this is 7
(2) says that y increases 12 units every time that x increases 4 Then the rate of change is: (increase in y / increase in x = 12/4 =3
(3) shows a table from which we can see that an increase of y in 8 corresponds to an increase of x in 2: rate of change = (8 - 0) , (2 - 0) = 4
(4) shos a line with slope (rate of change) given by: (12 - 0) / (2 - 0) = 12/2 = 6
Therefore, the greatest rate of change is shown by the first expression
y = 7 x

A trapezoid has a base 1 = 6 base = 8 and a height = 3 whats the area?
Answer:
[tex]area = 21[/tex]
Step-by-step explanation:
Area of trapezoid formula:
[tex]area = \frac{a + b}{2} h[/tex]
Given information:
a: 6
b: 8
h: 3
Using the given information,
[tex]area = \frac{6 + 8}{2} 3[/tex]
Add the numbers in the numerator
[tex]area = \frac{14}{2} 3[/tex]
Reduce fraction with 2
[tex]area = 7 \times 3[/tex]
Answer:
[tex]area = 21[/tex]

We have 4[12 -15]
Next, we have subtract in the parentheses since it's part of PEDMAS
12-15
After that, we get -3. Whenever a you multiply a whole number with a negative number, the whole becomes negative.
12- 15= -3
And Lastly, we multiply.
4x -3= -12

Solve for X:
5x - 14 = 8x + 4
a X = -6
b
X = 10/3
c
X = 6
d
X = -18/13
Answer:
a) x = -6
Step-by-step explanation:
5x - 14 = 8x + 4
-14 = 3x + 4
-18 = 3x
x = -6
Answer:
A) 5 (-6) - 14 = 8 (-6) + 4
- 30 - 14 = - 48 + 4
- 44 = - 44
Step-by-step explanation:
La respuesta correcta es la A, ya que x = - 6

Answer:
(sin x)^2*(sec x) is positive in QII
Step-by-step explanation:
(sin x)^2 is always 0 or positive. Here x lies in QII.
sec x is positive when the adjacent side is positive and negative when the adjacent side is negative. In QII the adjacent side is positive.
In summary, (sin x)^2*(sec x) is positive in QII

Answer:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex], [tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
Step-by-step explanation:
Use the quadratic formula to solve for all real solutions.
Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Plug in and solve:
[tex]x=\frac{-17\pm\sqrt{17^2-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-12(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-192}}{2(3)}\\\\x=\frac{-17\pm\sqrt{97}}{6}\\[/tex]
Since that's the farthest we can simplify to, your answers would be the positive and negative versions of the expression:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex]
and
[tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
