The answer is y=-2x+4. The y-intercept is (0,4) and the slope is -2.
Answer:height=20cm
Step-by-step explanation:
Length=100cm
Breadth=40cm
Volume=80 liters which is equal to 80000cm^3
volume=length x breadth x height
80000=100 x 40 x height
80000=4000 x height
Divide both sides by 4000
80000/4000=(4000xheight)/4000
20=height
Height=20cm
You would multiply 2020×88=177760
then add 177760+1010=178770
my calculations came out as 178770
The answer to the first problem is the top left corner because it is the only one with a -3 y-intercept and that's in the problem
To find the answer of the second problem you find the slope of the two points with the formula y2-y1 divided by x2-x1 and you just plug it in so 5+1 (the minus signs cancel out and turn into positives) divided by 4-2 and which is 6/2 which is 3 is your slope. then you could plug this information into a point slope form using either point I'm just going to choose the one with no negatives so plugging this in would be y-5=3(x-4) then you distribute the 3 and that gives you y-5=3x-12 then
+5 +5 add five to both sides of the equation and get
y=3x-7 and then you can put that into standard form which would be -3x+y=-7 and your answer would be the second one.
Answer:
8
Step-by-step explanation:
Formula for area = Length times width
72 divided by 9 = 8
Double check: 9(length) x 8 (width) = 72 (area).
Width = 8 inches
