Use the distributive property of multiplication to find 6×24.<br><br> Hint: 24= 4+20.

Marina86 [1]

Answer:

see explanation

Step-by-step explanation:

6 × 24 ← replace 24 by 4 + 20

= 6(4 + 20) ← multiply each term in the parenthesis by 6

= 24 + 120

= 124

Solve linear equation y=4-x y=x-4

Hatshy [7]

{ y = 4 - x
y = x - 4

Subsititute y = x - 4

[ ( x - 4 )] = 4 - x ]

isolate x for ( x - 4 ) = 4 - x

x = 4

For y = x - 4

Subsititute<span> x = 4
</span>
y = 4 - 4

y = 0

Solution

x = 4 and y = 0

hope this helps!

Find cos θ given that cos 2θ = 5/6 and 0 ≤ θ < π/2. Give an exact answer

trasher [3.6K]

$\bf \textit{Double Angle Identities}
\\ \quad \\
sin(2\theta)=2sin(\theta)cos(\theta)
\\ \quad \\
cos(2\theta)=
\begin{cases}
cos^2(\theta)-sin^2(\theta)\\
1-2sin^2(\theta)\\
\boxed{2cos^2(\theta)-1}
\end{cases}
\\ \quad \\
tan(2\theta)=\cfrac{2tan(\theta)}{1-tan^2(\theta)}\\\\
-------------------------------\\\\
$

$\bf cos(2\theta)=\cfrac{5}{6}\implies 2cos^2(\theta)-1=\cfrac{5}{6}\implies 2cos^2(\theta)=\cfrac{5}{6}+1
\\\\\\
2cos^2(\theta)=\cfrac{11}{6}\implies cos^2(\theta)=\cfrac{11}{12}\implies cos(\theta)=\pm\sqrt{\cfrac{11}{12}}$

now, bear in mind, the square root gives us +/- versions, so, which is it? well, we know the angle is in the range of "<span>0 ≤ θ < π/2", that simply means the 1st quadrant, so, we'll use the positive one then

</span> $\bf cos(\theta)=\cfrac{\sqrt{11}}{\sqrt{12}}\implies cos(\theta)=\cfrac{\sqrt{11}}{2\sqrt{3}}
\\\\\\
\textit{now, let's rationalize the denominator}
\\\\\\
\cfrac{\sqrt{11}}{2\sqrt{3}}\cdot \cfrac{\sqrt{3}}{\sqrt{3}}\implies \cfrac{\sqrt{11}\cdot \sqrt{3}}{2\sqrt{3^2}}\implies \cfrac{\sqrt{11\cdot 33}}{2\cdot 3}\implies \boxed{\cfrac{\sqrt{33}}{6}}$ <span>
</span>

HELP! What is the range of values for X? WILL GIVE BRAINLIEST!

andreev551 [17]

Answer:

Step-by-step explanation:

The range of a function is the set of all possible values it can produce.

For example, consider the function

$f(x)=x^{2}$

No matter what value we give to x, the function is always positive:

If x is 2, then the function returns x squared or 4.

If x is negative 2, then it still produces 4 since -2 times -2 is positive 4.

So the range of the function is

"all real numbers greater than or equal to zero".
