6-2x=y 14+3x=y plzzz helllllllllllllllp
pashok25 [27]

Answer:

(- \frac{8}{5}, \frac{46}{5} )

Step-by-step explanation:

Given the2 equations

6 - 2x = y → (1)

14 + 3x = y → (2)

Substitute y = 14 + 3x into (1)

6 - 2x = 14 + 3x ( subtract 3x from both sides )

6 - 5x = 14 ( subtract 6 from both sides )

- 5x = 8 ( divide both sides by - 5 )

x = - \frac{8}{5}

Substitute x = - \frac{8}{5} into either of the 2 equations for the corresponding value of y

Substituting into (1)

y = 6 - 2(- \frac{8}{5} ) = \frac{30}{5} + \frac{16}{5} = \frac{46}{5}

solution is ( - \frac{8}{5}, \frac{46}{5} )

A copy machine makes 28 copies per minute. How many copies does it make in 3 minutes and 45 seconds?
lina2011 [118]
<u>Convert minutes and seconds to minutes:</u>
\text{3 mins 45 seconds} \longrightarrow 3 \dfrac{3}{4} \text{mins}


<u>FInd 3 3/4 mins:</u>
\text{1 min} \longrightarrow 28 \text{ copies}

3  \dfrac{3}{4} \text{ min} \longrightarrow 28 \times 3\dfrac{3}{4} \text{ copies}

3  \dfrac{3}{4} \text{ min} \longrightarrow 28 \times \dfrac{15}{4} \text{ copies}

3  \dfrac{3}{4} \text{ min} \longrightarrow 105 \text{ copies}

Answer: It can make 105 copies.

Find the equation of the line that passes through (-1,-3) and is perpendicular to
miv72 [106K]

Answer:

y = -2x - 5

Step-by-step explanation:

2y = x - 3

y = 1/2x - 3/2

gradient = 1/2

perpendicular gradient = negative reciprocal = -2

y = -2x + c

(-3) = -2(-1) + c

-3 = 2 + c

-5 = c

Can someone please help me understand this?!?! i dont know what to even do.
Nonamiya [84]
Remember that a parallel line has the same slope...
So we already know the slope of the line containing point C is -4.

Using point slope equation, we can do...

y-y₁=m(x-x₁)
y-7= -4(x-4)
y-7- -4x+16
*Add seven to both sides...* y=-4x+23

There is you answer... hope this helps!
