Answer:
Lisa is not right.
Step-by-step explanation:
The equation Lisa is solving is x+6=8+x
The solution for the given value will be the value of x.
To solve for x we isolate the x term that is bring both x on one side of the equal sign.
Subtracting x both sides we have:
x-x+6=8+x-x
The x on both sides gets cancel and hence there is no value of x that will satisfy the equation x+6=8+x.
So Lisa solution is not right.
Answer:
Yes!
Step-by-step explanation:
GIVENS:
A = (-2,-5)
B = (1,-3)
C = (2,-5)
A' = (-2,5)
B' = (1,3)
C' = (2,5)
We can see analytically (through the points) and by inspection that the triangles seem to be reflected in the x-axis.
INSPECTION
The plot shows us this because any point we pick from one triangle we can see the reflected point on the opposite side (like there is a horizontal mirror on the x axis)
ANALYTICALLY
The points show us this because all the pairs (A and A' for ex) share the same x values but have negative y values!. So if we know point A is -2,-5, by taking the negative of the y we can see its reflected point A' which has the value of -2,5.
Answer:
3x+5
3(4)+5=12+5+17
Step-by-step explanation:
x is the hours
so you substitute the number of hours for x
Answer:
500 = 100%
20% = 60
Step-by-step explanation:
300 = 60%
50 = 10%
500 = 100%
100% = 300
10% = 30
20% = 60
Hope this helps!
