Y = –3x 6 y = 9 what is the solution to the system of equations? (–21, 9) (9, –21) (–1, 9) (9, –1)
Romashka [77]

we have

<u>The system of equations</u>

y=-3x+6 -------> equation 1

y=9 -------> equation 2

Substitute equation 2 in equation 1

9=-3x+6

subtract 6 both sides

9-6=-3x+6-6

3=-3x

Divide by -3 both sides

x=-1

the solution is the point (-1,9)

therefore

the answer is

the solution to the system of equations is the point (-1,9)

Ten less than three times the sum of a number and five is equal to twenty-nine. What is the number ?
kozerog [31]
Hello!
So the following would be your equation.
3(x+5)-10= 29
Your first step would be to use the Distributive Property based upon PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction). Since we have Parenthesis, we distribute first.
3(x+5)-10=29
^ ^
——————
So, your new equation would be—
3x+15-10=29
Now, you need to combine like terms—
15-10=29
3x+5=29
——————
Therefore your new equation is—
3x+5=29.
Now you need to move the constants (5,29) to one side of the equal sign. To do this, you would use the Subtraction Property of Equality and rid the 5–
3x+5=29
-5 -5
——————
Your equation is now—
3x=24.
Finally, you need to remove the 3 from x. This means you must use the Division Property of Equality, and rid the 3.
3x=24
— —
3 3
Your solved equation is—
X=8

Hope this helped!

What is the mean for the data set
Andrew [12]
First you would need to add up all of the data given, then divide the sum by 9 because there is 9 pieces of data. So it would be 229/9=25.4444444 repeating.

(X-1) squared + y squared = 36. What is the center and radius of the circle
Leni [432]

Answer:

  • center (1, 0)
  • radius 6

Step-by-step explanation:

<u>Given</u>

  (x -1)^2 +y^2 = 36

<u>Find</u>

  the circle's center and radius

<u>Solution</u>

Compare the given equation to the standard form equation for a circle.

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . centered at (h, k) with radius r

This tells you ...

  • h = 1
  • k = 0
  • r = √36 = 6

Your circle is centered at (1, 0) and has a radius of 6.
