Answer:448.5

Step-by-step explanation: first you have to see what 50% of 299 is so you do 299/2=149.5 so now they are marking it up so you do 299+149.5 =448.5

12. Write the slope-intercept form of the equation of the line.
wlad13 [49]

Answer:

The answer is the first choice.

Step-by-step explanation:

We can eliminate choices 2 and 4 because the y-intercept is wrong. The line passes through the y-axis at 3, so you would add 3 after the slope. Now we have choices 1 and 3. Choice 1 is y=-4/5x+3 and choice 3 is y=4/5x+3. When we do rise over run, we can use the points (0,3) and (5,-1). We get -4/5. Therefore, the answer is choice 1.

I hope this helps and please mark me as brainliest!

Solve each system by elimination<br><br> 5x+y=9<br> 10x-7y=-18<br><br> -4x+9y=9<br> x-3y=-6
tiny-mole [99]
5x + y = 9....multiply by 7
10x - 7y = -18
----------------
35x + 7y = 63 (result of multiplying by 7)
10x - 7y = -18
----------------add
45x = 45
x = 45/45
x = 1

5x + y = 9
5(1) + y = 9
5 + y = 9
y = 9 - 5
y = 4

solution is : (1,4)
=========================
-4x + 9y = 9
x - 3y = -6 ....multiply by 4
----------------
-4x + 9y = 9
4x - 12y = -24 (result of multiplying by 4)
---------------add
- 3y = - 15
y = -15/-3
y = 5

x - 3y = -6
x - 3(5) = -6
x - 15 = -6
x = -6 + 15
x = 9

solution is : (9,5)
