Answer:
-1
Step-by-step explanation:
"Gradient" is yet another term for "slope" or "rate of change." It is the ratio of "rise" to "run."
Here, the graph goes through grid intersections such that 1 to the right is 1 down. The "rise" is -1 for a "run" of 1, and the slop (gradient) is ...
m = rise/run = -1/1 = -1
The gradient of the graphed line is -1.
Answer:
1. 1/3 * 7 = 7/3 = 2 1/3 or two and one-third
2. 7/9 * 3/5 = (3*7)/(9*5) = 21/45
dividing numerator and denominator by 3
21/45 = 7/15 or start fraction seven over fifteen end fraction
3. 2 2/3 is equivalent to 8/3, then:
8/3 * 9 = 8 * 9/3 = 8 * 3 = 24
4. -4 1/2 is equivalent to -9/2
-2 1/3 = -7/3
Then:
-4 1/2 * (-2 1/3) = -9/2 * (-7/3) = -3/2 * (-7) = 21/2 = 10 1/2 or 10 one-half
5. (1/3) / (5/6) = 1/3 * 6/5 = 2/5 or two-fifths
6. 3 1/5 is equal to 16/5
16/5 ÷ 8 = 16/5 * 1/8 = 16/8 * 1/5 = 2 * 1/5 = 2/5 or The fraction is 2 over 5.
7. (-3/5) / (-3/4) = -3/5 * (-4/3) = 12/15
dividing each term by 3:
4/5 or The fraction is 4 over 5.
8. -3 1/5 si equivalent to -16/5
-3 1/5 ÷ 2/15 = -16/5 * 15/2 = -16/2 * 15/5 = -8 * 3 = -24
20 + 2x + 12 + 2x + 8
40 + 4x
