Answer:
Below.
Step-by-step explanation:
9(3+5) = 9×3+5:-
Now left side = 9*8 = 72 and
right side = 27 + 5 = 32
- so FALSE.
4^2 = 16
3(4) + 4 = 12 + 4 = 16
so TRUE.
Answer:
x=8
Step-by-step explanation:
4:3=x:6
Multiply the first set by 2
4*2 : 3*2
8:6
That means x =8
Answer:
y = -x/6 + 17
Step-by-step explanation:
Step 1: find the slope
y = 6x - 1
Equation of a line is
y = mx + c.
m - slope
m = 6
Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other
m = -1/6
Step 2 : using a point slope form equation
y - y1 = m( x - x1)
( -6 , 18)
x1 = -6
y1 = 18
y - 18 = -1/6(x - (-6)
y - 18 = -1/6( x + 6)
y - 18 = -x - 6 / 6
y = (-x - 6)/6 + 18
LCM = 6
y = (-x - 6 + 108)/6
y = -x + 102 / 6
y = -x/6 + 102/6
y = -x/6 + 17
The equation of the line is
y = -x/6 + 17
Answer:
c = 3/5
Step-by-step explanation:
5c+16.5=13.5+10c
Subtract 5c from both sides:
13.5+5c=16.5
5c=3
c = 3/5
78
/ \
39 2
/ \
3 13
you cannot simplify the square root of 78.
