Answer:

y=1

Step-by-step explanation:

Given the following question:

6=2(y+2)

In order to find the answer, we will rewrite the equation by switching the sides and then solve by dividing on both sides.

6=2(y+2)
2\left(y+2\right)=6
\frac{2(y+2)}{2} =y+2
6\div2=3
y+2=3
2-2=0
3-2=1
y=1

Hope this helps.

Tiffany babysits to earn extra money. She charges a fee of $15 per hour for one child, and then an added $30 overall for each ad
Hoochie [10]

Answer: Minimum for $150: 2 Hours

Step-by-step explanation: First, Tiffany charges $30 per additional child. If she babysits for 4 children, you do 30 x 4, which is equal to 120. That would be the cost for the children. Now, if she charges $15 PER HOUR, then you just add up $15 + $15, which is $30, and you add that $30 to the $120. Which is $150. There you have it. If this is wrong, correct me please!

for what value of x is <1 complementary to <2, ifm <1=5x+4 and m <2=7x+2 a.3 b7. c.1 d.14.5
antiseptic1488 [7]
Complementary angles are angles whose sum is equal to 90°.

m∠1 = 5x + 4
m∠2 = 7x + 2

m∠1 + m∠2 = 90°.

5x + 4 + 7x + 2 = 90
12x + 6 = 90
12x = 90 - 6
12x = 84
12x / 12 = 84/12
x = 7  Choice B.

m∠1 = 5x + 4 = 5(7) + 4 = 35 + 4 = 39
m∠2 = 7x + 2 = 7(7) + 2 = 49 + 2 = 51

39 + 51 = 90
90 =90

Use the figure below to find the exact values of the double angles.
scZoUnD [109]

Right away, we know that

\cos\beta=\dfrac{16}{20}=\dfrac45

which means

\sin\beta=\sqrt{1-\cos^2\beta}=\dfrac35

Then

\cos\beta=\cos2\left(\dfrac\beta2\right)=\cos^2\dfrac\beta2-\sin^2\dfrac\beta2

\sin\beta=\sin2\left(\dfrac\beta2\right)=2\sin\dfrac\beta2\cos\dfrac\beta2

Let x=\cos\dfrac\beta2 and y=\sin\dfrac\beta2. Then

\begin{cases}\dfrac45=x^2-y^2\\\\\dfrac35=2xy\end{cases}\implies\begin{cases}\cos\dfrac\beta2=\dfrac3{\sqrt{10}}\\\\\sin\dfrac\beta2=\dfrac1{\sqrt{10}}\end{cases}

from which we find

\tan\dfrac\beta2=\dfrac{\sin\frac\beta2}{\cos\frac\beta2}=\dfrac13

You can use the same ideas above to find the trig ratios for \dfrac\alpha2, starting from the given fact that \sin\alpha=\dfrac{16}{20}=\dfrac45.
