Answer:
X-intercepts are also called zeros, roots, solutions, or solution sets.
Y=-2x^2+2x-4. Should be correct
I’m guessing that this is for systems of equations?
n - nickels
d - dimes
These are the equations you start off with.
n = 5d-2
0.95 = 0.10d+0.05n
Substitute the top equation for n into the variable n in the bottom equation.
0.95 = 0.10d+0.05(5d-2)
Solve for d.
0.95 = 0.10d+0.25d-0.10
1.05 = 0.35d
3 = d
Substitute d into the top equation and solve for n.
n = 5(3)-2
n = 15-3
n = 12
There are 3 dimes and 12 nickels in the coin purse! Hope this helped <3
20 ÷ 2 (5,5)
20 ÷ 2 (25)
20 ÷ 50
.4
125 because it’s symmetrical between both
