Mathematics
1 answer:
damaskus [11]3 years ago

Answer:

y= 3 and x=5

Step-by-step explanation:

4y = 6(y-1)  distribute

4y = 6y-6   add -6y on both sides

-2y = -6  divide by -2 on both sides

y= 3

( the bottom line is twice the size of that one on the top) sooo,

2(x+4) = 4x-2   distribute

2x+8 = 4x-2    add 2 on both sides

2x+10 = 4x    subtract 2x on both sides

10 = 2x    divide both sides by 2

5= x

The cost of tickets to a circus is expressed by the function y = 4x + 2, where
-BARSIC- [3]

Answer:

2

Step-by-step explanation:

This is a linear function, written in the form y=mx+b, where m is the slope, or how many dollars each ticket costs in the case, and b is the initial value of the function, or in this case the cost before any tickets are added to the account.

Since 4x is the slope (4 times however many tickets one purchased), 2 is the initial value before we buy tickets.

You can also plug in 0 for x and get 4(0)+2=2

Hope I helped :D

Line BD is tangent to circle O at C, Arch AEC = 299, and ACE = 93. Find Angle DCE.
VladimirAG [237]
In triangle ACE,
we know C=93,E can be calulated by using arch angle AEC...what ever that is....,using this we get  A=180-(E+93)

So, by alternate segment theorem, DCE= A.

thats all i can say.

Easy algebra question below first correct answer gets brainliest
serg [7]

Answer:

Y = 27

Step-by-step explanation:

To find the the value of y when x = 4 simply substitute the given value of x

into the equation and solve for y

Equation given: y - 3x = 15

x = 4 * substitute 4 for x in given equation *

y - 3(4) = 15

Now solve for y

simplify multiplication

y - 12 = 15

Add 12 to both sides

y - 12 + 12 = 15 + 12

y = 27

So we can conclude that when x = 4 y = 27
