Answer:

y = -\frac{7}{4} + 3 , y = -\frac{1}{4}x - 3 : x = 4, y = -4

Step-by-step explanation:

\begin{bmatrix}y=-\frac{7}{4}x+3\\ y=-\frac{1}{4}x-3\end{bmatrix}

Substitute: y=-\frac{1}{4}x-3

Isolate x for: -\frac{1}{4} x - 3 = -\frac{7}{4} x + 3 : x = 4

For \:}y=-\frac{1}{4}x-3

Substitute: x = 4

y=-\frac{1}{4}\cdot \:4-3

-\frac{1}{4}\cdot \:4-3 = - 4

y = -4

The solutions to the system of equations are:

x=4,\:y=-4

Hope I helped, if so may I get brainliest and a thanks?

Thank you, have a good day! =)

a sweater that originally cost $40 is on sale for 10 percent off. what is the amount of the discount?
Andrej [43]
The retail price is 100% of the cost, and when 10% is taken off, that is the new price of the sweater.
100%-10%=90%
Then you convert the percentage to decimal and multiply the decimal with the retail price.

90%=0.9
0.9(40)=36
The new price of the sweater is $36.

Two parallel lines are 7 units apart. If you
Sedaia [141]

Answer:

14 units

Step-by-step explanation:

We apply the <em>Theorem of reflection over parallel lines.</em>

Theorem: The composition of two reflections over parallel lines that are h units apart is the same as a translation of 2h units.

Given that the two parallel lines are 7 units apart

h=7 units

2h= 2 X 7 =14 units

Therefore, the preimage and the final image will be 14 units apart.
