Step-by-step explanation:

\frac{1}{5 * 10^{6} }  = \frac{d}{350} \\\\d = \frac{350}{5 * 10^{6} } \\\\d = 7 * 10^{-5} km = 7 * 10^{-5} * 10^{6} cm = 70 cm

earnstyle [38]
If there are 18 students every one of the will pair up with 17 other students throughout the year so the total amount of pairs that can be made is 18x17=306 but since it’s not important if student A is paired with student B or student B with student A we should divide the total amount of pairs by two- 306:2=153 so in total there will be 153 projects finished

I WILL GIVE YOU BRAINLIEST IF YOU ANSWER THE WHOLE QUESTION.
kicyunya [14]

Answer:

B)y=2x   and     C) y=-7x+9

Step-by-step explanation:

Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.

Considering f(x)=y

f(x) = 2x  has a constant positive rate of slope 2.  

$\frac{dy}{dx}=2 $

f(x)=-7x+9 has a constant negative rate of slope -7

$\frac{dy}{dx}=-7 $

Pls help me with this problem!!!!
kolbaska11 [484]

Answer: 55°

Step-by-step explanation:

∠YAZ + ∠YAX = 180° because they are linear pairs

∠YAZ + ∠YAX = 180°

∠YAZ + 125 = 180

Subtract both sides by 125

∠YAZ = 55°

Hope that helped!
