Answer:
The second option
Step-by-step explanation:
The rate of change needs to stay constant.
The rate of change can be explained by looking at the "rise" (y) over the "run"(x)
The rate of change for the second option is 2. We know this because...
Rise(2)
----------
Run(1)
Try looking at one of the points, now go up 2 and over 1, you should now be at the second point, do it again but twice, you should now be at the third point. A proportional relationship must also go through the origin (0,0)
Answer:
the first answer is correct
the second answer is correct if they messed up on the question and meant to ask for the MAD of set B
I think the 3rd answer is incorrect (I got 1.09), so you might want to double-check your 3rd answer since it is asking for "times bigger", not how much bigger, which means how many times larger is the MAD of set A than that of set B and to find how many times bigger a number is than another number, you have to divide the first number by the second number.
Step-by-step explanation:
x = 160 gal
y = 80 gal
160 gallons of water and 80 gallons of premium antifreeze solution must be mixed.
I think you probably divide 7,200 gallons by 81 gallons since it's asking how many in one.
Answer:
y = 7x/8 - 53/8
Step-by-step explanation:
P(3,-4)
x = -7y/8 + 3
Isolate y and translate to slope-intercept form:
y = mx + b
x = -7y/8 + 3
x - 3 = -7y/8
8x - 24 = -7y
y = -8x/7 - 24/7
The slope of the equation is -8/7
The slope of the new equation will be perpendicular to the slope of the given equation which means it is the negative reciprocal.
y = mx + b where m = -1/(-8/7) = 7/8
y = 7x/8 + b
Plug in know values and solve for b:
-4 = 7(3)/8 + b = 21/8 + b
-4 - 21/8 = b
b = -32/8 -21/8 = -53/8
Plug in b into the equation:
y = 7x/8 - 53/8
