Answer:

The answer is 66.

Step-by-step explanation:

The lengths with the angles and the segments have the same length. For example, at the top angle, where it says 6, the length is also 6 for the other segment of the angle till the point. Where it says 17, you already know the shorter segment is 6 because the opposite length down there is also 6, so 17 minus 6 is 11. Now you know there is 6+6+11+11+6+6+10+10. This is a geometric rule but I forgot what it was called so it's hard to explain, but I hope that helped!

vodomira [7]

X= weight of TV
y= weight of CD

3x+5y= 62.5
3x+ 2y= 52
You can either solve for a variable, or eliminate a variable by subtracting the second equation from the first:

3x + 5y = 62.5
-(3x+2y = 52)
0 + 3y = 10.5, so y = 10.5/3 or 3.5.

Now plug y= 3.5 back into any equation to get x:

3x + 5(3.5) = 62.5
3x + 17.5 = 62.5
3x = 45
x = 15
Always check work. Both equations should be true for x=15, y= 3.5

What is the range of the function f(x) = 4x + 9, given the domain D = {-4, -2, 0, 2}?

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f( - 4) = 4( - 4) + 9 = - 7$

_________________________________

$f( - 2) = 4( - 2) + 9 = 1$

_________________________________

$f(0) = 4(0) + 9 = 9$

_________________________________

$f(2) = 4(2) + 9 = 17$

_________________________________

Thus ;

R = { - 7 , 1 , 9 , 17 }

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

The correct answer is (( D )) .

A rental car company charges $25 per day to rent a car and $0.12 for every mile driven. Violet wants to rent a car, knowing that

AleksAgata [21]

Answer:

The written inequality can be written as 0.12x + 25 <= 150.

Step-by-step explanation:

To solve the inequality you would plug in the 125 miles for x so 0.12(125) + 25 <= 150 0.12(125) would equal 15 so 15 + 25 <= 150 150/40 would equal 3.75 days but you cant have .75 of a day so Violet would have three days max to afford to rent the car while staying in her budget.
