Answer:
C
Step-by-step explanation:
Convert to slope intercept form:
y = mx + b
2x + y = 7
y + 2x = 7
y + 2x - 2x = 7 - 2x
y + 0x = -2x + 7
y = -2x + 7
Slope = -2
Y-intercept = 7
The volume of a cube can be found by cubing the side length. So, since 7 cubed is 343, the answer would either be c or d. Then, since the unit for volume is units cubed, the answer is D.
Answer:
add 21 to both sides to get everything on one side
x^2 - 10x + 21 = 0
do factorization, guess and check
(x - 7) (x -3) = 0
x =7, and x =3
Answer: It Diego i think please don’t be mad at me if you get it wrong
0.14x + 25 = 0.19x
25 = 0.05x
x = 500
the costs of the two plans will be equal after 500 minutes
