Answer:
19/4 or 4.75
Step-by-step explanation:
Week 1: 1 1/8 = 1.125
Week 2: -2 5/8 = -2.625*
Week 3: 1 3/4 = 1.75
Week 4: -1 1/2 = -1.5
Week 5: 2 1/8 = 2.125*
2 1/8 - (-2 5/8) = 2.125 - (-2.625)
19/4 or 4.75
Answer: D. y = -4x + 4
Step-by-step explanation:
Notice that the y-intercept is when x is zero and the x intercept is when y is 0.
and to write in the equation in slope intercept form , you will need the slope and the intercept.
We will use the y and x intercepts to find the slope, by find the difference in their y coordinates and dividing it by the difference in their x coordinates.
y intercept: ( 0,4)
x intercept: (1,0)
y coordinates difference: 4 - 0 = 4
x coordinates difference: 0 - 1 = - 1
Slope: 4/-1 = -4
Since the slope is -4 and the the y intercept is 4 , the equation will be
y = -4x + 4
Im not sure ask ur teacher
The ratio can be determined as,
Thus, the requried ratio is 7:12.
