Answer:

23(2+7y-())=0

Step-by-step explanation:

(10+13)(2+7y=)

We move all terms to the left:

(10+13)(2+7y-())=0

We add all the numbers together, and all the variables

23(2+7y-())=0

Answer:

0 and 2

Step-by-step explanation:

f(x) = g(x) will be the input or x value at which f and g have the same output or y value. Look in the table where two numbers repeat right next to each other.

−1 −7/2 −9/2


0 −3 −3


1 −2 −3/2


2 0 0


3 4 3/2


4 12 3


5 28 9/2

There are two solutions to f(x) = g(x) which are x=0 and x=2.

A pair of vertical angles has measures<br> (3x + 4) and ( 73 – 9)<br> What is the value of x?
sergij07 [2.7K]

Answer:

20

Step-by-step explanation:

Vertical angles are always equal to each other. So the answer is

3x + 4 = 73 - 9                 Are you sure this is what the question is?

3x + 4 = 64                      Subtract 4 from both sides

 <u>    -4      -4</u>

3x = 60                           Divide by 3

3x/3 = 60/3

x = 20

Point R is located at (1, 2) on a coordinate grid. Point S is located at (4, 5) on the same
Aleksandr-060686 [28]

Answer:

4.2 units

most likely answer choice B

Step-by-step explanation:

(1, 2) and (4, 5)

To find the distance between two points, we use the distance formula:

d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }

Let's plug in what we know.

d = \sqrt{(4 - 1)^2 + (5 - 2)^2 }

Evaluate the parentheses.

d = \sqrt{(3)^2 + (3)^2 }

Evaluate the exponents.

d = \sqrt{(9) + (9) }

Add.

d=\sqrt{18}

Evaluate the radical.

d = 4.24

Round to the nearest tenth.

d = 4.2 units

*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.

Hope this helps!
