Since the function y= f(x) is decreasing on the interval (5, 7), y = -f(x) is INCREASING on the interval (5,7), because the slope is inverted due to the negative sign.

A farmer has 3/4 acre of land. He will use all the land and plant different vegetables in 1/16 -acre sections. How many sections
kati45 [8]

Answer: 12 sections of 1/16 acre

Step-by-step explanation:

We want to find how many sections of 1/16 acre we can have in a total area of 3/4 acre.

This is equal to the quotient between 3/4 and 1/16

Remember that if we have two rational numbers (a/b) and (c/d) the quotient can be writen as:

(a/b)/(c/d) = (a/b)*(d/c) = (a*d)/(b*c)

The quotient we want to solve is:

(3/4)/(1/16) = (3/4)*(16/1) = (3*16)/4 = 12

Then you can have 12 sections of 1/16 acre

Line j is parallel to line k. Find the m
Rufina [12.5K]

Answer:

- 8.14 = m = slope

Step-by-step explanation:

We know from the diagram that  8x-7  + 5x+18  = 180    so x = 13

  so 8x -7  =  97

slope = tan 97 = -8.14

Solve by factorising x² + 11x + 30 = 0<br> dont get think one could someone explain this please.
nalin [4]

Answer:

x={-5,-6}

Step-by-step explanation:

x²+11x+30=0

x²+5x+6x+30=0 (as 5*6=30 and 5+6=11)

x(x+5)+6(x+5)=0

(x+5)(x+6)=0

so

x+5=0

x+6=0

therefore

x=-5

x=-6
