Answer:

(x,y) (9,4)

Step-by-step explanation:

-2x+7y = 10

x -3y = -3 (move x to the other side)

-2x +7y = 10

x = -3 + 3y (put in for x)

-2 (-3 +3y) +7y =10 ( slove for y)

6-6y +7y = 10

6+y = 10

y = 10-6

y = 4

go back slove for x

x = -3+3x4

x = 9

What are the x and y intercepts of the equation y=log(3x+3)-2
tatyana61 [14]

y \:  =  \:  log(3x \:  +  \: 3)  \:  -  \: 2
For x-intercept,
y = 0,
log(3x+3) = 2
(3x + 3) = antilog(2)
x = (antilog(2) - 3)/3
x ≈ 32.3333
For y-intercept,
x = 0,
y = log(3) - 2
y ≈ -1.5228

Solve the radical equation 3/(√x+3)=1.Be sure to check for extraneous solutions.
jeka94

Answer:

The solution to the equation is x = 0.

Step-by-step explanation:

Hi there!

First, let´s write the equation:

3/(√x+3)=1

To solve the equation, let´s start multiplying both sides by (√x+3)

3 = √x+3

subtract 3 to both sides of the equation

0 = √x

0 = x

Now, let´s check the solution:

3/(√x+3)=1

x = 0

3/(√0 + 3) = 1

3/3 = 1

1 = 1

Then, x = 0 is the solution to the equation.

It's not 65 I dont know how but when I put 65 it says it's wrong.

The correct answer should be 95. I don’t know how you did it but try the PEMDAS method (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
