X1= -3 -root 29 /2
x2=-3+ root 29 /2
Answer:
-15, -17
Step-by-step explanation:
x^2 + 32x = –255 move the -255 to the left
x^2 + 32x +255=0
What two number when multiplied equal 255? Those same two numbers when added make 32. 17*15 make 255 and added is 32
(x+15)(x+17) For x+15=0 move the 15 to the other side. x= -15. Same with x+17=0 is x= -17
x= -15, -17
Median is 4 because it’s in the middle. mean is 4 because it the average of them all. mode is 3 and 4 because it the numbers that repeat the most. range is 6 because 8-2
Answer:
E
Step-by-step explanation:
because you divide 1 3/4 (1.75) over 1/5 (.2) to get 8 3/4 (8.75)
~ : to represent sign of proportionality
y ~ 1/x
y = k/x
x=20, y=4
4 = k/20
k = (20×4) = 80
y = 80/x
x=35, y = 80/35 = 2.29
The proportional constant k = 80
The function is: y = k/x
The new value of y is: 2.29
