The standard form of the equation that represents the number of quarters, q, and the number of dimes, d, that Austin has in his piggy bank is 5q + 2d = 270. This can be change to slope intercept form to see the clearer picture. By dividing the whole equation by 2, so the equation become d= -2.5q + 135.
This means that Austin has initially 135 dimes in his piggy bank and he is losing 2.5 dimes per quarter.

Answer and Step-by-step explanation:
is the equation to find the axis of symmetry of a quadratic equation.

-3 = a
18 = b
10 = c
Now we plug the values into the equation.

The axis of symmetry is on the line x = 3.
#teamtrees #WAP (Water And Plant)
Plug in both x and y values into the equation.
4(5) + 4
20 + 4
24
24 is your answer. I hope this helps!
Answer: 7 years
Step-by-step explanation:
let x be the age of Mary
so John's age will be 2x
the equation becomes
2x+x=21
3x=21
x=21/3
x=7
Answer:
None
Step-by-step explanation:
For there to be a correlation it needs to either be in a line or have equal stuff on both sides
