Y=4x and 3x+y=-21. Substitute

gizmo_the_mogwai [7]

value of x= -3 and value of y = -12

Solution set is (-3,-12)

Step-by-step explanation:

We need to solve the system of equations using substitution

The system of equations are:

$y=4x\\3x+y=-21$

Solving:

Let

$y=4x\,\,eq(1)\\3x+y=-21\,\,eq(2)$

Solving:

Putting value of y from equation 1 into equation 2

$3x+y=-21\\3x+4x=-21\\7x=-21\\x=-21/7\\x=-3$

So, value of x = -3

Now, putting value of x into equation 1 and find value of y

$y=4x\\y=4(-3)\\y=-12$

Value of y = -12

So, value of x= -3 and value of y = -12

Solution set is (-3,-12)

Angle DCA is 120°. What percent of the circle's area does this section represent?

dolphi86 [110]

A circle is 360

so we're going to set up a proportion

120 x
------ = ------
360 100

then cross multiply and divide

120 times 100=12000/360=33.3333333

so the answer is C. 33

I hope I've helped!
