Cos x + square root 3 = -cos x

Answer: x=15/2

Step-by-step explanation: Divide both sides by 4 so 64/4  Simplify 64/4 ​to  16. 2x=16−1 2x=15 Divide both sides by 2  x=  

15/2

Answer:

z = 10

Step-by-step explanation:

Distribute 2 to the terms in the parentheses:

2(2z + 5) = 50​

4z + 10 = 50

Subtract 10 from both sides

4z = 40

Divide each side by 4

z = 10

So, the answer is z = 10

Answer:

10

Step-by-step explanation:

1. Factorize left side.

2*2z+2*5=50

4z+10=50

2. Subtract 10 from both sides

4z=50-10

4z=40

3. Divide both sides by 4

z=40/4

z=10

Answer:

A translation of 3 units to the right and a translation of one unit upwards.

Step-by-step explanation:

When we analyze translations of whole figures, all the points in the figure suffer the same translation, then we only need to analyze the translation of one of the points.

This means that we can only see the translation from A to A'

First, let's find the coordinates of each point:

A (2, 3)

A' (5, 4)

The translation is given if we calculate the difference between these coordinates:

A' - A =  (5, 4) - (2, 3) = (5 - 2, 4 - 3) = (3, 1)

The change in the x-value is 3.

The change in the y-value is 1.

Then we can conclude that:

A' is 3 units at the right of A

A' is 1 unit above A.

Then the translation is:

A translation of 3 units to the right and a translation of one unit upwards.

Answer:

every odd number that squares up and add 2 will give an even answer

Answer:

see explanation

Step-by-step explanation:

Given that p is an odd number , then

p² is always an odd number

Adding 1 to an odd number gives an even number.

So p² + 1 is always even for p odd

Step-by-step explanation:

Let's stick to one unit to facilitate things. I'm going to use quarts as the unit.

1 gal = 4 qt

Initial value = 3 gal 2 qt = 14 qt

Change = 2 gal 3 qt = 11 qt

14 qt - 11 qt = 3 qt

Answer:

x= -3 and y= 0

Step-by-step explanation:

5x+2y=-15

2x-2y=-6    

7x        =-21

x= -3

Putting value of x in equation 1  

5(-3) +2y=-15

-15+2y= -15

2y= 0

y= 0

This can be solved with the help of matrices

In matrix form the above equations can be written in the form

[tex]\left[\begin{array}{ccc}5&2\\2&-2\/\end{array}\right][/tex]  [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  = [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]

Let

[tex]\left[\begin{array}{ccc}5&2\\2&-2\/\end{array}\right][/tex] = A  [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  = X  and  [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]= B

Then AX= B

or X= A⁻¹ B

where  A⁻¹= adj A/ ║A║   where mod A≠ 0

adj A=  [tex]\left[\begin{array}{ccc}-2&-2\\-2&5\/\end{array}\right][/tex]

║A║= ( 5*-2- 2*2)= -10-4= -14≠0

X= A⁻¹ B

 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]    =- 1/14  [tex]\left[\begin{array}{ccc}-2&-2\\-2&5\/\end{array}\right][/tex]   [tex]\left[\begin{array}{ccc}-15\\-6\\\end{array}\right][/tex]

 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]    =- 1/14     [tex]\left[\begin{array}{ccc}-2*-15&+ -2*-6\\-2*-15&+ 5*-6\\\end{array}\right][/tex]

 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  =- 1/14 [tex]\left[\begin{array}{ccc} 30&+12\\30&+-30\\\end{array}\right][/tex]

 [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  =- 1/14 [tex]\left[\begin{array}{ccc}42\\0\\\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  = [tex]\left[\begin{array}{ccc}-42/14\\0/-14\\\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]  = [tex]\left[\begin{array}{ccc}-3\\0\\\end{array}\right][/tex]

From here x= -3 and y= 0

Answer:

[tex]y=3(2)^{x-5}+6[/tex]

Step-by-step explanation:

Let the equation of the exponential function with base 2 is,

[tex]y=a(2)^{x+c}+d[/tex]

Here, a = vertical stretch

c = Horizontal shift

d = Vertical shift

If this function has a vertical stretch by a factor of 3,

Equation will be,

[tex]y=3(2)^{x+c}+d[/tex]

If this function has a shift of 5 to the right,

Equation of the function will be,

[tex]y=3(2)^{x-5}+d[/tex]

If this function has a shift of 6 units upwards,

[tex]y=3(2)^{x-5}+6[/tex]

Answer:

40

Step-by-step explanation:

SO im guessing if its the full graph one box counts 1.

So the top side counts 8

The left one is 15

The perimeter means adding all the sides together.

We already have 2. But finding the hypotenuse would not be easy from graph so we will use Pythagorean theorem.

a^2+b^2=c^2

8^2+15^2 = c^2

64+225 = c^2

289 = c^2

c = 17

so the perimeter is 8+15+17 = 40
