Step-by-step explanation:
Perpendicular lines are lines which intersect at 90 degrees which have negative reciprocal slopes. The slope of the line y = 3/2x + 2 is 3/2. The slope of the line perpendicular to it will be -2/3. Substitute m = -2/3 and (6,-3) into the point slope form of a line.
Answer:
-1x - 1
Step-by-step explanation:
the factor of x is the slope of the line in the form of y/x.
it simply says how many units y changes for a given change of x.
in our diagram we can see that when x changes one unit to the right (positive), y changes 1 unit down (negative).
so, the slope or factor of x = -1/1 = -1
and when x=0, y=-1.
so, the constant offset in the line equation is -1 too.
so, it is
y = -x - 1
or as explicit factor for x
y = -1×x - 1
Alright so the first one involves in shading.
You can see that Jack and Renee have two bars with rectangles inside the bar.
Jack took 3/4 hours or in words, three out of four. So in Jack's bar, shade 3 boxes and leave one unshaded.
Renee took 2/3 or two out of three. Shade 2 boxes in Renee's bar and see the difference.
As you can see, Jack has more shade length than Renee and that could only mean one thing:
Jack took longer to fix the tire than Renee.
The symbol that represents this is 3/4 > 2/3
The second activity has the same case.
Water: 3/5 means that you have to shade three boxes and leave the other two unshaded.
Sports Drink: 4/6 means that you have to shade four boxes and leave the other two unshaded.
As you can see again, there is more sports drink than the water since the shade length is longer in the sports drink than on the water.
This meant that she poured in more sports drink than water.
The third activity is just as simple, you just need to visually make up your own sections. Do the shading then see which one is bigger then just input the sign (hint: the first one is < and the second one is >)

Answer:
7 the answer is 7
Step-by-step explanation:
1. We assume, that the number 20 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 20 is 100%, so we can write it down as 20=100%.
4. We know, that x is 35% of the output value, so we can write it down as x=35%.
5. Now we have two simple equations:
1) 20=100%
2) x=35%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
20/x=100%/35%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 35% of 20
20/x=100/35
(20/x)*x=(100/35)*x -
20=2.85714285714*x -
20/2.85714285714=x
7=x
x=7
now we have:
35% of 20=7
we multiply both sides by x
then we divide both sides by 2.85714285714 to get x
