The answer is D, here’s why:
You know the slope-intercept form is y=mx+b
mx being the slope and b being the y-intercept.
y=-4/7x + 9 is already in that form.
A is not the answer because the y is supposed to be by itself.
B is not the answer because again, the y is not by itself.
C is not the answer because the y is also not by itself.
In the slope-intercept form, the y must be by itself and the slope (mx) and the y-intercept must be on the other side.
Hope this helps.
Step-by-step explanation:
the explanaition of the answer and solution is in the picture, check it out. this is for question 14
A function is odd if:
f ( - x ) = - f ( x )
A ) f ( - x )= 0.8 ( - x ) ^3 = - 0.8 x^3 = - f ( x )
Answer: A ) f ( x ) = 0.8 x^3 is an odd function.
Functions B ) and C ) are even and D) is neither even nor odd.
Answer:
d

-3(4x+2)-2x
-12x+6-2x
-14x+6
Answer:
Maria (I THINK)
Step-by-step explanation:
Tanya is running 70 yards in all, while maria would be running more based on the pythagorean theorem
The pythagorean theorem is that on a right triangle, the square root of the two legs equal the hypotenuse
40^2+ 70^2 =c^2
6500=c^2
square root both sides
and roughly c= 80.6 yards so maria runs more
(Im not sure it is a right angle though?)
