Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
You know:
m = 3
b = -2 So substitute/plug it into the equation
y = mx + b
y = 3x + (-2)
y = 3x - 2 Your answer is the 2nd option
Non proportional I think idk
Answer:
14, 21, and 63
Step-by-step explanation:
we can set the three unknown numbers as x, y, and z
so
x + y + z =98
now we are given that the first (x) is seven less than the second (y)
x = y - 7
the third number (z) is three times the second (y)
z = 3y
since we have an equation for z and x in terms of y, we can plug it into the first equation and solve for y.
(y-7) + y + (3y) =98
y - 7 + y + 3y =98
y + y + 3y =105
5y = 105
y=21
now that we know y, we can plug its value into either the second or the third equation to find x or z (I chose to find z first)
z = 3y
z = 3(21)
z = 63
now we can plug in y to find x
x = y - 7
x = 21 - 7
x = 14
so the three numbers should be 14, 21, and 63
Answer:
The first histogram is the answer.
Step-by-step explanation:
Like any other questions, you can use the process of elimination to answer this question.
There are only one fruit that has a water content of 60 - 64 %
Right away you can eliminate the second answer choice.
There are two fruits that has a water content of 65 - 69 %
All the other three has the same thing
There are only two fruits that has a water content of 70 to 74 %
Right away answer choice three can be eliminated
There are 4 fruits that are 75 - 79 % full with water
Both has same thing
There are 9 friuts that are 80 - 84 % full with water
THERE ARE 2 FRUITS THAT CONTAIN 85 - 89 % water
THE ANSWER IS THE FIRST HISTOGRAM.
