Answer:
b
Step-by-step explanation:
vertical line through x at one
vertical lines have undefined slopes
can take two points to verify (1,1) (1,2) m=<u> 2-1</u>
1-1
<u> 1 </u>
0 undefined zero in denominator
B)16
add the two equations and equal it to 90 and solve to get 16
Answer:
x = 12 and y = 0
Step-by-step explanation:
Use elimination by adding the equations together.
-2x + 15y =-24
2x + 9y = 24
---------------
24y = 0
y=0
Then substitute y = 0 into one equation to find x.
-2x + 15(0) = -24
-2x + 0 = -24
-2x = -24
x = 12
The equivalent expression of 4b+13/2 is (8b+13)/2.
Given an expression be 4b+13/2.
We are required to find the equivalent of the expression 4b+13/2.
Expression is combination of numbers, symbols, fractions, coefficients, determinants, indeterminants. In an expression we do not find any equal to sign. It shows some relationship. In this expression b is the only variable that exists. If we have been given some value of th expression at some point then we can get the value of variable.
The expression is 4b+13/2.
Taking LCM first.
The LCM of any two numbers is basically the value that is evenly divisible by the two given numbers.
=(8b+13)/2
Hence the equivalent expression of 4b+13/2 is (8b+13)/2.
