Answer:
(3, 9)
Step-by-step explanation:
Set 3x and 2x+3 equal to each other forming an equation in x.
3x=2x+3
Solve for x.
x=3
Substitute the given value of x into the equation y=3x.
y=3x3
Solve for y.
y=9
(x, y) = (3, 9)
Hope this helps :)
Answer:
y = 4x - 1
Step-by-step explanation:
The slope of the line (m) is 4. The line crosses the y-axis at a y-value of -1, so b = -1.
For being in proportion,
Product of means = Product of extremes
Here,
only pair pair fulfills that
8 : 12 :: 18 : 27
8 × 27 = 12 × 18
216 = 216
Answer:
A bill
Step-by-step explanation:
A bill becomes a law. Search up a bill becomes a law schoolhouse rock.
This is called a literal equation, or an equation with multiple variables. You solve it the same as you solve any other equation, but the variables stay there the whole time.
If they want "r" to be the subject, then they want you to solve for r. This means that you need to get the variable r by itself on one side of the equation, but still have the equation be equivalent to it original form.
I'm going to show you, in steps, how to solve this problem:
<span>V=πr²h
Divide both sides by "</span>π²h<span>"
</span>V/π²h=(πr²h)/<span>π²h
</span>
V/(π²h)=r
Your answer is r=V/<span>π²h</span>
