Given:

Point = ( -4,8).

To find:

The image point of (-4, 8) after a translation right 4 units and up 2 units.

Solution:

We know that, if a figure translated 4 units right and 2 units up, then the rule of translation is

(x,y)\to (x+4,y+2)

The point is (-4,8).

Putting x=-4 and y=8, we get

(-4,2)\to (-4+4,8+2)

(-4,2)\to (0,10)

Therefore, the image of point (-4,8) is (0,10).

1. What is an equation for the line with slope 2/3 and y-intercept 9?
Monica [59]
Question 1:

 The generic equation of the line is given by:
 y = mx + b

 Where,
 m: slope of the line
 b: cutting point with the y axis
 Substituting values ​​we have:
 y = \frac{2}3}x + 9

 Answer:
 an equation for the line with slope 2/3 and y-intercept is:
 y = \frac{2}3}x + 9

 Question 2:

 The standard equation of the line is given by:
 y-yo = m (x-xo)

 Where,
 m: slope of the line
 (xo, yo): ordered pair that belongs to the line
 The slope of the line is:
 m =  \frac{y2-y1}{x2-x1}
 Substituting values:
 m = \frac{1-(-3)}{3-1}
 m = \frac{1+3}{3-1}
 m = \frac{4}{2}
 m = 2

 We choose an ordered pair:
 (xo, yo) = (3, 1)

 Substituting values:
 y-1 = 2 (x-3)

 Rewriting:
 y = 2x - 6 + 1

y = 2x - 5
 Answer:
 An equation in slope-intercept form for the line that passes through the points (1, -3) and (3,1) is:
 y = 2x - 5


 Question 3:

 For this case, since the variation is direct, then we have an equation of the form:
 y = kx
 Where,
 k: constant of variation.
 We then have the following equation:
 -4y = 8x
 Rewriting we have:
 y = \frac{8}{-4}x

 y = -2x
 Therefore, the constate of variation is given by:
 k = -2

 Answer:
 the constant of variation is:
 k = -2

 Question 4:

 For this case, since the variation is direct, then we have an equation of the form:
 y = kx
 Where,
 k: constant of variation.
 We must find the constant k, for this we use the following data:
 y = 24 when x = 8
 Substituting values:
 24 = k8
 Clearing k we have:
 k =  \frac{24}{8} 

 k = 3

 Therefore, the equation is:
 y = 3x
 Thus, substituting x = 10 we have that the value of y is given by:
 y = 3 (10)

y = 30 Answer:
 the value of y when x = 10 is:
 y = 30

Tpy6a [65]

Answer:

SA = 2520 ft^2

Step-by-step explanation:

a = 21ft

b = 29ft

c = 20ft

h = 30ft

SA = 2A_{B} + (a+b+c)h

A_{B} = s(s﹣a)(s﹣b)(s﹣c)

s = \frac{a + b + c}{2}

SA= ah + bh + ch + \frac{1}{2} \sqrt{-a^4 + 2(ab)^2 + 2(ac)^2 - b^4 + 2(bc)^2 - c4}

SA= (21 * 30) + (29 * 30) + (20 * 30) +

       \frac{1}{2} \sqrt{-(21)^4 + 2(21 * 29)^2 + 2(21 * 20)^2 - (29)^4 + 2(29 * 20)^2 - (20)^4}

SA = 2520 ft^2

Answer:

  C  log3(√((x -4)/x)

Step-by-step explanation:

The applicable rules of logarithms are ...

  log(a/b) = log(a) -log(b)

  log(a^n) = n·log(a)

The base is irrelevant, as long as all logs are to the same base.

__

  \dfrac{1}{2}(\log_3{(x-4)}-\log_3{(x)})=\dfrac{1}{2}\log_3(\dfrac{x-4}{x})=\boxed{\log_3\left(\sqrt{\dfrac{x-4}{x}}\right)}
