X = –6 3x − 2y = –6 solve using substetution <br> NEED FAST
kondaur [170]

Answer:

(x = -6), (y = -6)

(-6,-6)

Step-by-step explanation:

X=-6

3x - 2y = -6

3(-6) - 2y = -6

-18 - 2y = -6

What you do to one side, you do to the other. And when you take it over to the other side, you'll have to turn -18 into a positive 18.

-2y = 18 - 6

-2y = 12

Divide both sides by -2

y = -6

A dog walker charges a flat rate of $6 per walk plus an hourly rate of $30. How much does the dog walkercharge for a 45 minute w
leonid [27]

hello

from the question given, the dog walker charges a flat rate of $6 and an extra $30 per hour.

we can write out an equation in function notation

let the number of hours be represented by x

f(x)=6+30x

now we can proceed to solve the cost of the walk for 45 minutes

\begin{gathered} 1hr=60\min s \\ \text{xhr}=45\min s \\ x=\frac{45}{60} \\ x=\frac{3}{4} \\ \text{therefore 45mins = 3/4 hours} \end{gathered}

now we can input the value into the equation and know the cost for 45 minutes walk

\begin{gathered} f(x)=6+30x \\ x=\frac{3}{4} \\ f(x)=6+30(\frac{3}{4}) \\ f(x)=6+22.5 \\ f(x)=28.5 \end{gathered}

from the calculation above, the cost of 45 minutes walk will cost $28.5

2 - 4x = 3x - 12<br> Solve for x
vova2212 [387]

Answer:

x = 2

Step-by-step explanation:

Step 1: Write out equation

2 - 4x = 3x - 12

Step 2: Add 4x on both sides

2 - 4x + 4x = 3x + 4x - 12

2 = 7x - 12

Step 3: Add 12 on both sides

2 + 12 = 7x - 12 + 12

14 = 7x

Step 4: Divide both sides by 7

14/7 = 7x/7

2 = x

Step 5: Rewrite

x = 2
