What does the line 5x+2y=8 look like?

1 answer:

5 0

The correct answer would be D. The plot of the line 5x+2y = 8 is slanted right downwards. To predict, we write the equation into slope-intercept form as follows:

y = mx + b where m is the slope and b is the y-intercept form

5x + 2y = 8
y = -5x/2 + 4

As we can see, the slope is negative so the graph should slope to the right downwards.

Which fraction is in reduced form?

kompoz [17]

Answer:

C 5/13

Step-by-step explanation:

A fraction is written in reduced form if there are no common factors in the numerator and denominator. Since you know your multiplication tables, you can easily identify the common factors:

A 20 = 5·4, so 4 is a common factor 4/(4·5) = 1/5

B 6 = 2·3, 9 = 3·3, so 3 is a common factor (2·3)/(3·3) = 2/3

C 13 is not a multiple of the prime number 5, so there are no common factors. 5/13 is a reduced fraction

D 14 = 2·7, 21 = 3·7, so 7 is a common factor (2·7)/(3·7) = 2/3
