Answer:
y = -10
Step-by-step explanation:
Hey there!
To solve this you first have to distribute the -3 to y and 5. When you do this you get...
-3y - 15 = 15
Add 15 on both sides you get...
-3y = 30
Divide by -3 and you get...
y = -10
Hope this helped :)
Answer:
3/8
Step-by-step explanation:
The slope of the line is -2/-5
√x+3 = 2
First we should simplify the equation by squaring both sides:
x + 3 = 4
Isolate x by taking 3 off both sides:
x = 1
We should ALWAYS check that our answer is correct after working out the value of x. We can do this by substituting x into the original equation:
√x + 3 = 2
Turns into:
√1 + 3 = 2
Which turns into:
√4 = 2
Which is true, therefore we can confirm:
x = 1
