Answer:
The table is a quadratic function
Step-by-step explanation:
Given
The attached table
Required
Tell if it is a quadratic function
The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.
(1) Subtract adjacent y values.
(2) Subtract adjacent differences in (1) above
Notice the calculated differences in (2) are the same.
<em>Hence, the table is a quadratic function</em>
first you find the slope by making using the quation for slope
(7-3)/(0-5) and you find your slope is 4/-5. Then you can plug this into point slope form using on of the coordinates so:
y-y1=m(x-x1) --> y-3=-4/5(x-5)
then you distribute the -1 so -----> y-3=-4/5x+4 and then move the 3 over
so the answer is y= -4/5x+7
Answer:
wz is the corresponding part
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
KEEP 1/4 CHANGE the sign to multiplication FLIP 1/2 to 2/1
new equation: 1/4 x 2/1
now we can solve
we do: 1 x 2= 2
so 2 is our nominator
then we do: 4 x 1= 4
so 4 is our denominator
combine the nominator and denominator and we get
1/2 which in decimal form is 0.5
76.47% of 15 is 11.47 you just multiply 76.47 x 15
