Answer:
38
Step-by-step explanation:
times 3x5 then add 18+20
If xy=0 assume that at leas 1 is zero
set it to zero
0=2a^2-16a+32
undistribute 2
0=2(a^2-8a+16)
2*0=0 so assume
a^2-8a+16=0
factor
(a-4)(a-4)=0
set to zero
a-4=0
a=4
when a=4, equation equals zero
A is the correct answer because if you times them all together it equals 84
Answer:
First graph = 2/9
Second graph = 3/7
Third graph = 1/5
Step-by-step explanation:
Unit rate can be defined as number of y units changed with respect to the number of x units changed.
Consider the first graph, we can see that for x=9, the change that occurs in y is equals to 2 units. So its units can be given as 2/9
Consider the second graph, we can see that for x=7, the change that occurs in y is equals to 3 units. So its units can be given as 3/7
Consider the third graph, we can see that for x=5, the change that occurs in y is equals to 1 units. So its units can be given as 1/5.
