HOPE IT HELPS!!!!

I am guessing that you mean 2cos2(45° - A) = 1 + sin2A

According to a double angle identity, 2cos2θ - 1 = cos(2θ)

So, 2cos2(45° - A) - 1

= cos (90° - 2A) =cos90°cos2A + sin90°sin2A = (0)cos2A + (1)sin2A = sin2

Thus, 2cos2(45° -A ) = 1 + sin2A

Answer:

3(x+6)

Step-by-step explanation:

Parenthesis after a number typically means multiply, so 3 times the sum of an unspecified number (x), plus 6 would be 3 (x+6)

9y^2 + 11 = 19

9y^2 = 8

9y = [tex]2\sqrt{2}[/tex]

y = [tex]\frac{2\sqrt{2} }{9}[/tex]

Answer:

x= 10

YZ=60

Step-by-step explanation:

X____Y____Z

XZ= XY+YZ

81 = (2x+1) + 6x

81 = 8x +1

8x = 81 -1

8x =80

x = 80/8

x = 10

YZ = 6x = 6(10) = 60

Answer:

x = 12 or x = -6

Step-by-step explanation:

Solve for x over the integers:

abs(x - 3) = 9

Split the equation into two possible cases:

x - 3 = 9 or x - 3 = -9

Add 3 to both sides:

x = 12 or x - 3 = -9

Add 3 to both sides:

Answer: x = 12 or x = -6

Answer:

-(5/14)

Step-by-step explanation:

Make the denominators the same.

-9/14 (Stays)

2/7(Times by 2 to make denominator 14)

-9/14 + 4/14 = -5/14

Final asnwer is -(5/14)

Answer:

-5/14

Step-by-step explanation:

first make them the same denominator

we can multiply the 2/7 by 2/2 to get 4/14 so it becomes really easy to add :)

-9/14 + 4/14 = -5/14!

it's already in simplest form so there's nothing else you have to do :D

Answer:

y-intercept is 8 and slope is -2

Step-by-step explanation:

General equation of a line:

[tex]y = mx + b[/tex]

m » slope

b » y-intercept

Our equation given:

[tex]{ \boxed{y = - 2x + 8}}[/tex]

by comparison with general equation

m » -2

b » 8

Answer:

Step-by-step explanation:

If we know that D is the midpoint, then 2x + 7 = 4(x-3). Doing the algebra on that gives us

2x + 7 = 4x - 12 and

19 = 2x so

x = 9.5

Answer:

B

Step-by-step explanation:

The steps in the original function of f of B are

1. multiply by 2

2. subtract 9

Then the steps of the inverse equation would be

1. add 9

2. divide by 2

And this is what we see here. G is actually the inverse of f. Therefore B is the correct answer. If you repeat the same process for the other answers you'll find that it doesn't actually make an inverse.

You can also graph these to see whether or not its an inverse.

[tex]\\ \sf\longmapsto AC=\sqrt{100}[/tex]

[tex]\\ \sf\longmapsto AC=10[/tex]

The simplified expression after combining like terms is 2(6r-10).

An expression is combination of variables, numbers and operators.

In the given expression 12r-8-12

The expression has three terms

The r in the expression is a variable.

Minus and plus are the operators of the expression.

We have to add the constant terms in the expression.

12r-(8+12)

12r-20

2(6r-10)

Hence, the simplified expression after combining like terms is 2(6r-10).

Answer:

[tex]42 = - 48 + 3r[/tex]

add 48 to either sides:

[tex]42 + 48 = ( - 48 + 3r) + 48 \\ 90 = 3r \\3r = 90[/tex]

divide all sides by 3:

[tex] \frac{3r}{3} = \frac{90}{3} \\ \\ { \boxed{ \boxed{r = 30}}}[/tex]

Answer:

r = 30

Step-by-step explanation:

42 = -48 + 3r

42 + 48 = -48 + 48 + 3r

90 = 3r

[tex]\frac{90}{3} =\frac{3r}{3}[/tex]

30 = r

Step-by-step explanation:

The perimeter of a parallelogram is twice the sum of the length of a longer and a shorter side.

The length can be evaluated by the distance formula between two points (x_1,y_1), (x_2, y_2)

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For the longer side,

[tex]d=\sqrt{(7-(-4))^2+(3-2)^2}=\sqrt{122}[/tex]

or the shorter side,

[tex]d=\sqrt{(7-6)^2+(3-(-2))^2}=\sqrt{26}[/tex]

Therefore, the perimeter is given by,

[tex]2(\sqrt{122}+\sqrt{26})\approx254.2[/tex]
