4x+15≥−9and8x−6≤34 For the first one, you have 4x + 15 is greater than or equal to -9. You need to isolate the x so first subtract 15 from both sides. so it would be x≥−6 is this what
is this what you are looking for

Q. Find the total cost. $ 990 T.V., 9% tax

Maslowich

Answer:$1,079.1

Step-by-step explanation:

Cost of TV = $990

Sales tax = 9% of TV cost= 9/100 × 990

= 0.09 x 990 = $89.1

Total cost of TV will be calculated by cost of TV + sales tax

=$990 + $89.1

=$1,079.1

Use substitution to solve the following system of equations.-3x - 4y = 2−3x−4y=2minus, 3, x, minus, 4, y, equals, 2-5 = 5x + 5y−

Scrat [10]

Answer:

The solution to this system is (-2,1)

Step-by-step explanation:

The given system of equations is;

$-3x-4y=2$ ...eqn1

and

$-5=5x+5y$ ....eqn2

We make y the subject of the second equation to get:

$-5y=5x+5$

$\implies y=-x-1$ ...eqn3

We put eqn3 into eqn1 to get;

$-3x-4(-x-1)=2$

We expand to get:

$-3x+4x+4=2$

$-3x+4x=2-4$

Simplify both sides to get:

$x=-2$

Put x=-2 into eqn3

$\implies y=--2-1$

$\implies y=1$

The solution to this system is therefore (-2,1)
