Answer:
B
Step-by-step explanation:
To find the slope, find the vertical distance and the horizontal distance between the points. Then write the distances as a ratio.
6 - 3 = 3
0.4 - 0.2 = 0.2
The slope is 3/0.2 = 15.
Let’s do 3x - 8 ≤ 23 first.
You need to rearrange this so that x is on its own.
+8 to both sides
3x ≤ 31
/3 on both sides
x ≤ 31/3
Then the second, -4x + 26 ≥ 6
-26 from both sides
-4x ≥ -20
/-4 on both sides
x ≥ 5
So x is greater than or equal to 5, which can also be written as 5 ≤ x
And for the first one, x is less than or equal to 31/3, which can still be written as x ≤ 31/3, so your final answer is:
5 ≤ x ≤ 31/3
The first and last one are the same the teo middle ones are the same. the two middle ones equal -20 and the last and first one equal 20. this is for the question above problem 3.2
Well you want to do 7.8 divided by 2 which is 3.9. Then you add that to 7.8 to signify that is it 1 1/2 which is 11.7. You subtract that from 60 and you get 48.3 and that is your answer
