Step-by-step explanation:
The symbol for absolute value is two straight lines surrounding the number or expression for which you wish to indicate absolute value.
This is a tricky question lol. 5/2 = 2.5 , which is half of 5 ... the picture will illustrate half of 5
Area is trapezium =
A=1/2h(a+b)
84=1/2(6)(7+b)
84=3(7+b)
84=21+3b
3b=84-21
B=63/3
B= 21 cm
I’m sorry if my answer turned out to be wrong but I tried my best so best of luck !!
Answer:
6a-6n+36
Step-by-step explanation:
-10a-9n+16-30+3n+15a+50+a
Combine a...
-10a+15a= 5a+a=6a
Combine n...
6a-9n+16-30+3n+50
-9n+3n= -6n
6a-6n+ 16-30+50
Combine # w no variable
Answer: 6a-6n+36
Step-by-step explanation:
the slope of a line is always the factor of x.
here : 1/2
it is the ratio y/x indicating how many units y changes, when x changes a certain angina amount of units when going from one point to another.
a perpendicular slope puts x and y upside-down and flips the sign.
here : -2/1 = -2
so, the equation looks like
y = -2x + b
b is the y-intercept, and we get this by putting the x and y coordinates of the given point into this equation and solve for b :
-1 = -2×-2 + b
-1 = 4 + b
b = -5
the full equation is therefore
y = -2x - 5
