Switch the second equation to equal y so...
y=-2x-3
then plug in for y in the first equation
2x+4(-2x-3)=6
2x-8x-12=6
-6x=18
x=-3
now plug in for y
2(-3)+y=-3
-6+y=-3
y=3
answer (-3,3)
Answer :
step-by-step explanation:
From the question,
the diameter:
The radius :
Area of a circle is given as
By substitution,
Hence the area of the home is
Answer:
<em>Yes</em>
Step-by-step explanation:
g(x) = - 
x +
y = - x + ....... <em>(1)</em>
<em>(1)</em> × 4
4y = - x + 1
x = - 4y + 1
y = - 4x + 1
f(x) = - 4x + 1
∴ f(x) and g(x) <em>are inverses</em>
The rule of law of the square root of constants is taking the nearest divisible number which has a square root of an integer. In this case, 50 is divisible by 25. Hence sqrt of 50 is 5 sqrt 2. The sqrt of a variable applies the multiplication rule. x^6 is raised to 0.5 equal to x^3. Hence the answer is 5 x3 sqrt 2.
Answer:
The word "of" in the question means multiply, so you need to multiple these two fractions.
2/3 x 4/5 = 8/15
