Answer:
b.
b.
Step-by-step explanation:
scientific notation should have one positive in front of the decimal point, then any number (>=1) of positions after the decimal point, followed by the multiplication with the property power of 10.
the only number not following that rule is b (2 positions in front of the decimal point).
4x - 2y = 6
2x - y = 3
are the same line, as we can multiply the second equation by 2 and get exactly equation 1.
so, both lines have the same slope and the same y-intercept. therefore, they have infinitely many solutions.
F(x) = 5x - 4.....slope is 5
g(x) : (0,1)(2,5)
slope = (5 - 1) / (2 - 0) = 4/2 = 2 .....slope is 2
h(x) : (1,14)(4,15)
slope = (15 - 14) / (4 - 1) = 1/3..slope = 1/3
so the smallest slope would be : h(x) with a slope of 1/3
They hiked about 4.7 times as far or it could also be 4 7/10 times as far
Lets check all the choices:
A. subtraction:
(3x+2)-(4y-11)=3x+2-4y+11=3x-4y+13
similarly, (4y-11)-(3x+2)=-3x+4y-13
both are polynomials (of 2 variables)
B. (3x+2)(4y-11)=12xy-33x+8y-22, which is a polynomial
C. (3x+2)+(4y-11)=3x+2+4y-11=3x+4y-9, which is a polynomial
D.
both
and
are rational expressions in 2 variables, not polynomials
Answer: D
Answer:
490
Step-by-step explanation:
because the 7 (last digit) is not less than 5, it rounds up to 490
