Answer:
y=4/3x
Step-by-step explanation:
First you have to divide the 3x on both sides, causing the Y to be by itself and you'll have your answer for X.
Answer:
x=25
Step-by-step explanation:
angles are vertical angles so they are equal
set expressions equal to each other: 5x-10=3x+40
subtract 3x from both sides: 2x-10=40
add 10 to both sides: 2x=50
divide by 2: x=25
Answer:
29.12%
Step-by-step explanation:
Given that :
A = 49
B = 50
C = 38
D = 60
E = 75
Total = (49 + 50 + 38 + 60 + 75) = 272
Pie chart % for each :
A = (49 / 272) * 360 = 64.85
B = (50 / 272) * 360 = 66.18
C = (38 / 272) * 360 = 50.29
D = (60 / 272) * 360 = 79.41
E = (75 / 272) * 360 = 99.26
Difference between C and D
(79.41 - 50.29) = 29.12%
Answer:
Step-by-step explanation:
The function y = x² + 16 is positive for any value of x, hence the graph has no intersection with the x-axis and therefore has no real zero's.
If no zero's, -4 also can't be its zero.
