7.95*0.06 to get amount of tax you're paying
$0.477is how much tax you're paying. (round it up to 0.48)
7.95-0.48
$7.47
The answer is $7.47
Probability of drawing a second red
first red not replaced = 1/5
1/3*1/5=1/15
A graph which shows a discrete domain is a set of points not connected between them, while a graph which shows a continuous domain is a continuous curve.
So for these types of questions you want to substitute the value given into the equation...
So for a,
f(x)=2x-7
f(-3)=?
well instead of x you place -3,
so
f(-3)= 2*-3 - 7
So now you solve using order of operations (PEMDAS)
So,
2*-3=-6 So,
f(-3)=-6-7
-6-7=-13
So,
f(-3)=-13
Try to do that for the others and I'll let you know if you're right. Good luck!

Answer:
- to eliminate x: multiply the first by 3, and the second by -4
- to eliminate y: multiply the first by 2, and the second by 5
Step-by-step explanation:
Pick the variable you want to eliminate. Determine the coefficients of that variable in the two equations. Negate one of them. Multiply each equation by the coefficient that came from the other equation.
__
<u>To eliminate x</u>
The x-coefficients are 4 and 3. If we negate 4, then the resulting y-coefficient will be positive. We choose to multiply the first equation by 3, the second by -4.
Here is the result of adding those:
3(4x +5y) -4(3x -2y) = 3(7) -4(-12) ⇒ 23y = 69
<u>To eliminate y</u>
The y-coefficients are 5 and -2. If we negate -2, then the resulting x-coefficient will be positive. We choose to multiply the first equation by 2 and the second by 5.
Here is the result of adding those:
2(4x +5y) +5(3x -2y) = 2(7) +5(-12) ⇒ 23x = -46
