Step-by-step explanation:
3m+20=4m-10
-3m+10-3m+10
30=m
<u>A. X=0 Y=5</u>
Those 2 equations are a system. You answer is the value of x and y.
13x+3y=15
y=5-4x
First, lets make each equation fit into y=mx+b
13x +3y=15 y=5-4x
-13x -13x y=-4x+5
3y= -13x +15
Let's use the elimination method to solve this.
y= -4x+ 5 multiply top by 3
3y=-13x+15
3y=-12x+15
3y=-13x+15 subtract the equations
<u>0=x</u>
Lets use the x we just found to solve for y.
y=4x+5
y=4(0)+5
<u>y=5</u>

Step-by-step explanation:
A={1,2,3,4,5,6}
R={(x,y):y is divisible by x}
We know that any number (x) is divisible by itself.
(x,x)∈R
∴R is reflexive.
Now,(2,4)∈R [as 4 is divisible by 2]
But,(4,2)∈
/
R. [as 2 is not divisible by 4]
∴R is not symmetric.
Let (x,y),(y,z)∈R. Then, y is divisible by x and z is divisible by y.
∴z is divisible by x.
⇒(x,z)∈R
∴R is transitive.
Hence, R is reflexive and transitive but not symmetric.
Answer:
about 54
Step-by-step explanation:
due to the fact that it is just about a reflection but the thing is that it must be around 90, but it really depends on the angle you measure it at.
