G(x)=3x+2 and h(x)=ax+B

AfilCa [17]

Answer:

B= $\frac{3}{-2}$

a= $\frac{11}{2}$

Step-by-step explanation:

$g^{-1}$ = $\frac{x-2}{3}$ (g of -1 formula)

$g^{-1}$ (14)= $\frac{14-2}{3}$

= $\frac{12}{3}$

= 4

h(x)=ax + B

h(1)= a+ B

$g^{-1}$ (14)=h(1)

4=a + B

a= 4-B

h(4)=22

4a+B=22

4(4-B)=22

16-4B=22

-4B=6

B= $\frac{6}{-4}$

B= $\frac{3}{-2}$

a= 4+ $\frac{3}{2}$

a= $\frac{8+3}{2}$

a= $\frac{11}{2}$

Find the circumference and the area of a circle with diameter 2 cm . Use the value 3.14 for π , and do not round your answers. B

Fynjy0 [20]

Circumference= 2×pi×R
Area= pi× R^2
Since Diameter=2 cm ---> Radius is 2× diameter , so R=4 cm

Circumference=2×3.14×4= 25.12 cm
area=3.14× (4)^2= 50.24 cm^2

What does it mean if the rate of an airplane is modeled by the function f(x) = 1x + 500?

Julli [10]

The questions seems to be lacking some information. By rate I'm going to assume position and in that scenario the answer would be B because the position function is modeled by a linear function.

Answer:

a. 8x + 4y = −4

17x + 2y = −28

Step-by-step explanation:

{6x + 2y = −6

{3x − 4y = −18

{6x + 2y = −6

{1½x - 2y = −9

$\displaystyle \frac{7\frac{1}{2}x}{7\frac{1}{2} = -\frac{15}{7\frac{1}{2}} \\ \\ x = -2$ [Plug this back into both equations above to get the y-coordinate of 3]; $\displaystyle 3 = y$
