Let's take a look at D:

D) y = (x-1)^2 - 16 Compare this to
y = (x-h)^2 + k This is the std. equation of a parabola in vertex form.

You can see, by comparison, that h=1 and k= -16; these are the coordinates of the vertex, clearly shown in the diagram.

Since the coefficient of (x-h)^2 is +1, the graph opens upward (which the given graph confirms), and is neither compressed nor stretched vertically.

The line perpendicular to y=3/4x+7 containing (3,-4)

Ainat [17]

Answer:

y = - $\frac{4}{3}$ x

Step-by-step explanation:

1). $y_{1}$ = $m_{1}$ $x_{1}$ + $b_{1}$

$y_{2}$ = $m_{2}$ $x_{2}$ + $b_{2}$

$y_{1}$ ⊥ $y_{2}$ if $m_{2}$ = - $\frac{1}{m_{1} }$

2). ( $x_{3}$ , $y_{3}$ )

y - $y_{3}$ = m( x - $x_{3}$ )

~~~~~~~~~~~~~~~~~~

y = $\frac{3}{4}$ x + 7

$m_{1}$ = $\frac{3}{4}$

$m_{2}$ = - $\frac{4}{3}$

( 3, - 4 )

y - ( - 4) = - $\frac{4}{3}$ ( x - 3 )

y + 4 = - $\frac{4}{3}$ x + 4

y = -  $\frac{4}{3}$  x

At the beginning of the season, carl had to remove 50 dead orange trees from his farm while each of the remaining trees produced

Len [333]

Answer:

y > (x - 50) * 210

Step-by-step explanation:

Given :

Number of dead trees = 50

Number of oranges produced by each of the remaining trees > 210

Let total number of trees = x ; total number of oranges produced = y

Hence, number of oranges produced, y

y > number of remaining trees * number of oranges produced per tree

y > (x - 50) * 210

Workout the value of the largest angle

Elanso [62]

Step-by-step explanation:

These angles all add up to 360° because they form a circle, so b + b + 2b + 5b = 360°, and b = 40°. The largest angle is 5b which is 5 * 40 = 200°.

Find the value of x. Then find the angle measures of the polygon.

Bess [88]

Question 11

x+x+1/2x+1/2x=360

x+x+2/2x+=360

x+x+x=360

3x=360

x=120

Then substitute 120 in the place of x

x1=120

x2=120

1/2(120)=60

To check your answer you can add 60+60+120+120 the should be equal to 360

Question 12

x+x+(x-45)+(x-45)+(x-45)=540

x+x+x-45+x-45+x-45=540

5x-135=540

5x=540+135

5x=675

x=675/5

x=135

Then substitute 135 in the place of x

x1=135

x2=135

135-45=90

To check your answer you can add 135+135+90+90-90 the should be equal to 540

Hope it helps
