Needs to be 20 characters long, noticed people had bad answers, I hope I did this right I’m a bit rusty. :) I recommend using Photomath and Desmos to help with stuff as well!!

Answer:
Step-by-step explanation:
We can let d represent the number of dimes. Then the number of quarters is 23-d, and the total value of the change is ...
0.10d + 0.25(23 -d) = 4.70
-0.15d + 5.75 = 4.70
1.05 = 0.15d . . . . . . . . add 0.15d -4.70 to both sides
7 = d . . . . . . . . . . . . . . divide by 0.15
There were 7 dimes in the change purse.
__
There were 23-7 = 16 quarters.
Answer:
<h2>(-1, 9)</h2>
Step-by-step explanation:
f(x)= -2 (x - 2) ( x - 4)
if x=2 ⇒ f(x)=y=0 ⇒ graph of f(x) intercept x axis in (2,0)
if x=4 ⇒ f(x)=y=0 ⇒ graph of f(x) intercept x axis in (4,0)
if x=0 ⇒f(x)= -2 *(-2)*(-4)= - 16 ⇒ graph of f(x) intercept y axis in (0,- 16)
⇒ f(x)= -2 (x - 2) ( x - 4) is the answer
H^2-36
factoring the above we shall have:
h^2-36
=h^2+0h-36
=h^2+6h-6h-36
=h(h+6)-6(h+6)
=(h-6)(h+6)
the factors are (h-6) and (h+6)
the answer is A
