Choose the correct words from the drop-down menu to make a true statement about the system of equations.

Mathematics
1 answer:
Artist 52 [7]2 years ago
4 0

Answer:

C

Step-by-step explanation:

Given the 2 equations

y = \frac{1}{3} x + 2 → (1)

- x + 3y = 6 → (2)

Substitute y = \frac{1}{3} x + 2 into (2)

- x + 3(\frac{1}{3} x + 2) = 6 ← distribute left side

- x + x + 6 = 6, that is

6 = 6 ← True

This statement indicates the system has infinitely many solutions

(7)/(3) of it is 5 (5)/(6)
slava [35]

let's firstly convert the mixed fraction to improper fraction and then take it from there, keeping in mind that the whole is "x".

\stackrel{mixed}{5\frac{5}{6}}\implies \cfrac{5\cdot 6+5}{6}\implies \stackrel{improper}{\cfrac{35}{6}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{7}{3}x~~ = ~~5\frac{5}{6}\implies \cfrac{7}{3}x~~ = ~~\cfrac{35}{6}\implies 42x=105\implies x=\cfrac{105}{42} \\\\\\ x=\cfrac{21\cdot 5}{21\cdot 2}\implies x=\cfrac{21}{21}\cdot \cfrac{5}{2}\implies x=1\cdot \cfrac{5}{2}\implies x=2\frac{1}{2}

Can someone help please!! i will give brainliest
olga_2 [115]

Answer:

1. $427.50

2. 50 hours

Step-by-step explanation:

1. First, find your salary at minimum hours, which is $360. Then, take your second equation, plug in 45, and solve using PEMDAS. This will give you $427.50

2. To solve this, you'll need to set it up like so:

495 = 13.5 (x - 40) + 360

Your next step will be to distribute the number outside the parentheses. This will give you:

495 = 13.5x - 540 + 360

Simplify, like so:

495 = 13.5x - 180

Solve.

495 = 13.5x - 180

+180             +180

This will give you:

675 = 13.5x

Divide each side.

675 = 13.5x

------    -------

13.5     13.5

  50 = x

A line passes through the points (-4,1) and (-3,3). This line can be modeled by the equation y = mx + b.
docker41 [41]

Answer:

m= 2

b=9

Step-by-step explanation:

-4, 1 -3,3

put it into y2-x2 divided by y1-x1

y2= 3

x2= 1

y1= -3

x1=-4

3-1 divided by -4--3= 2/1    =2x

get one of the points either -4,1 or -3,3

If you use -4,1    -4=x 1=y

put it into y=mx+b and you get 1= -4(2)+b    simplify

1=-8+b add 8 to other side b=9
