A: ( f + g) (x) = -7x - 3
B: ( f + g) (x) = x-7
C: (f + g) (x) = -x + 3
D: ( f + g) (x) = 7x - 7

Answer:

The answer is B.

Step-by-step explanation:

r- (-12.4) = -15.8

r + 12.4 = -15.8

   -12.4     -12.4

r = -28.2

Answer:

B. -28.2

Step-by-step explanation:

r - (-12.4) = -15.8

r + 12.4 = -15.8

r = -15.8 - 12.4

r = -28.2

Answer:

(- 2, 4 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) , then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = A (4, 6 ) and (x₂, y₂ ) = B (- 8, 2 )

midpoint = ( [tex]\frac{4-8}{2}[/tex] , [tex]\frac{6+2}{2}[/tex] ) = ( [tex]\frac{-4}{2}[/tex] , [tex]\frac{8}{2}[/tex] ) = (- 2, 4 )

Midpoint be p(x,y)

P(x,y)=

[tex]\\ \sf\longmapsto \left(\dfrac{4-8}{2},\dfrac{6+2}{2}\right)[/tex]

[tex]\\ \sf\longmapsto \left(\dfrac{-4}{2},\dfrac{8}{2}\right)[/tex]

[tex]\\ \sf\longmapsto (-2,4)[/tex]

Answer:

Answer:

a) 26

b) 26/3

Step-by-step explanation:

a) 4 and 1/3 = 13/3

13/3 x 6/1 = 13/1 x 2/1

b) 2 and 3/5 = 13/5, 3 and 1/3 = 10/3

13/5 x 10/3 = 13/1 x 2/3

Answer:

1(kilometer/hour) = 1000(meters) / 3600(seconds) can also be expressed as 1(kilometer/hour) = 5/18 (meters/second), which is its simplified form. To convert km/h to m/s, directly multiply the given value of speed by the fraction 5/18

Step-by-step explanation:

so the answer wil be 20.8333 m/s

So we know that x = 90º because it is a right angle. And angle B also has to be 47º because it is a reflection of angle C. And all the angles of any triangle are equal to 180º, so if we do 180-(90+47)=43. So now we know that y=43º and x=90º Your welcome, please give me brainlest.

With given conditions we can state:

Comparing with the answer choices, correct choice is C.

Answer:

3 < S < 17

Step-by-step explanation:

picture the 10 side as the bottom

the 7 side pivoting on the right end of the 10 leg

when it swings toward the left the shortest the third side can be is >3

when it swings to the right the longest the third side can be is <17

Step-by-step explanation:

first find out the area of sector ECF

π(10)² × 40°/360°

=100π×1/9

=100π/9 m²

now find the area of sector DCG

π(2)² × 40°/360°

=4π/9 m²*

so the area of the shaded region would be the big sector minus the small sector

so

100π/9 - 4π/9

=96π/9

=33.5 m² (3sig.fig.)

*Note that 4π/9 DOES NOT equal to 2π/3

4/9 DOES NOT EQUAL TO 2/3

Answer:

2 (x_2-x_1) + 2(y_2-y_1)

Step-by-step explanation:

Length of rectangle = l ( say )

=> l = √(x_1 - x_2)² + (y_2-y_2)²

=> l = √(x_1-x_2)² = x_1 - x_2 / x_2 - x_1

Let breadth = b ,

=> b = √(x_1-x_1)² + (y_2-y_2)²

=> b = y_2-y_1

So , perimeter will be ,

2(l + b)

2 (x_2-x_1) + 2(y_2-y_1)
