Answer:
y=1/2x-2
Step-by-step explanation:
perpendicular lines have a neg. reciprocal for the slope.
for example:
in this equation y=-2x+1
-2 is the slope and the negative reciprocal would be 1/2
hence, the slop of our new line is 1/2
y=1/2x+b
we can substitute the coordinates given for x and y:
2=1/2(8)+b
2=4+b
-2=b
hence the new equation is y=1/2x-2
5.5(7.5 + x)
Multiply 7.5 and x by 5.5.
41.25 + 5.5x
41.25 is the area of the blue part of the mural, and 5.5x is the area of the red part of the mural.
Answer:
Check the solution in both equations. The solution is ( − 1, 2). Solve the system by graphing: {− x + y = 12 x + y = 10 . Solve the system by graphing: {2x + y = 6 x + y = 1 . In all the systems of linear equations so far, the lines intersected and the solution was one point.
Hope it helps!!!
15a^3b^4c^5----> answer B
you can only multiple like terms so
(5x3)= 15
now just add
a+a^2= a^3
b + b^3 = b^4
c^5 + 0= c^5
Answer:
The rational numbers are 
and the irrational functions are 
.
Step-by-step explanation:
A rational number can be expressed in the form of 
, where p and q are integers and q is not equal to 0. For example 
.
An irrational function can not be expressed in the form of , where p and q are integers and q is not equal to 0. For example 
.
If any number is multiplied by a irrational number then the resultant number is an irrational number.
By the above definition we can conclude that:
The number 
is a rational number.
Therefore 
is an irrational number.
Therefore 6.25 is a rational number.
Therefore 0.01045 is a rational number.
The number 
is a rational number.
The number 
is an irrational number.
Therefore 
is an irrational number. The numbers with recursive bar are always rational numbers.
