Answer:
Step-by-step explanation:
Let the family's expense be x
In the Chang family's budget, 0.6% of the expenses are for internet service.
Then expense for internet service=0.6 % of x
The fraction of family's expense is for internet service =
Hence the fraction of family's expense is for internet expense=
system of equations algebraically are shown in the table.
y = -x2 +2x - 9
y = -6x + 6
(5,-24) and (3, -12)
(5,36) and (3, 24)
(-5, -24) and (-3, 12)
(-5, 36) and (-3, 24)
Step
Equation
-x² + 2x -9 = -6x + 6
0 = x2 – 8x+15
0 = (x - 5)(x-3)

Answer:
(3,-12) and (5,-24)
Step-by-step explanation:
Given the system of two equations
Equate right sides of these two equations:
Rewrite this equation:
If x=3, then
If x=5, then
You get two solutions (3,-12) and (5,-24)
The solution set of the system of equation is (5, -24) and (3, -12)
The given systen of equation is one linear and one quadratic. Given the syatem of equations
Equating bothequations will give
Equate to zero
Factorize
Recall that ;
y = -6x + 6
If x = 5
y = -30 + 6
y = -24
If x = 3
y =-6(3) + 6
y = -12
Hence the solution set of the system of equation is (5, -24) and (3, -12)

x > what number?
12 + 5x > 2(8x - 6) - 7x
12 + 5x > 16x - 12 - 7x
5x - 16x + 7x > -12 - 12
-4x > -24 / : (-4)
x < 6
