find the value of y. (3y+1) (8x-61) (6x-13)

Answer:

82 and 98.

Step-by-step explanation:

set up 2 equations

x+y=180

2x+16=180

you start by solving the second equation to find one of the angles.

180-16= 164

2x=164

164÷2= 82

x=82

since you've solved that equation, add in the missing variable to solve for the next one

82+y=180

180-82= 98

Step-by-step explanation:

Solve inequality:

Highlight the points to the right from -5

Answer:

[tex]n>-5[/tex]

Step-by-step explanation:

−105<−7(5−2n)

Divide both sides by −7. Since −7 is negative, the inequality direction is changed.

[tex]\frac{-105}{-7}[/tex] > 5−2n

Divide −105 by −7 to get 15.

15>5−2n

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

5−2n<15

Subtract 5 from both sides.

−2n<15−5

Subtract 5 from 15 to get 10.

−2n<10

Divide both sides by −2. Since −2 is negative, the inequality direction is changed.

n>[tex]\frac{10}{-2}[/tex]

Divide 10 by −2 to get −5.

n>−5

Answer:

$512.5

Step-by-step explanation:

Given data

P= $500

R=2.5%

T= 1 year

The compound interest formula is

A=P(1+r)^t

substitute

A=500(1+0.025)^1

A=500(1.025)

A=500*1.025

A=$512.5

Hence the balance is $512.5

Answer:

Step-by-step explanation:

We can let d represent the number of dimes. Then the number of quarters is 23-d, and the total value of the change is ...

  0.10d + 0.25(23 -d) = 4.70

  -0.15d + 5.75 = 4.70

  1.05 = 0.15d . . . . . . . . add 0.15d -4.70 to both sides

  7 = d . . . . . . . . . . . . . . divide by 0.15

There were 7 dimes in the change purse.

__

There were 23-7 = 16 quarters.

Are they a system or separate inequalities? I'm not sure but either way I will solve each:

[tex]\begin{bmatrix}-3x+5>20\\ \frac{1}{2}x-12<6\end{bmatrix}[/tex]

[tex]-3x+5>20,\\-3x>15,\\x<-5[/tex]

[tex]\frac{1}{2}x-12<6,\\\frac{1}{2}x<18,\\x<36[/tex]

Now if it were a system, the solution would be x<-5, since x<36 is the restriction. Otherwise just take x<-5 and x<36 independent of each other.

Answer:

x< -5, x<36

Step-by-step explanation:

[tex]-3x+5>20} \atop {\frac{1}{2}x-12<6 }} \right. \\[/tex]

Start with the first equation and solve for x

-3x+5>20

     -5   -5

-3x>15

/-3    /-3

x< -5

Do the second:

[tex]\frac{1}{2}x-12<6[/tex]

     +12    +12

[tex]\frac{1}{2}x[/tex]<18

/0.5    /0.5

x< 36

Answer:

  2/15

Step-by-step explanation:

The given expression for θ can be rewritten to ...

  5sin(θ + arctan(-3/4)) = 0

This will have solutions ...

  θ +arctan(-3/4) = nπ

  θ = nπ - arctan(-3/4) = nπ + arctan(3/4)

__

The corresponding values of sine and cosine will be ...

  sin(arctan(3/4)) = 3/5

  cos(arctan(3/4) = 4/5

or both values may be negative. Either sign will give the same result in the expression we're to find.

  (2sin(θ) -cos(θ))/(sin(θ) +3cos(θ)) = (2(3/5) -(4/5))/(3/5 +3(4/5))

  = ((6 -4)/5)/((3+12)/5) = 2/15

  [tex]\boxed{\dfrac{2\sin\theta-\cos\theta}{\sin\theta+3\cos\theta}=\dfrac{2}{15}}[/tex]

Answer:

  2

Step-by-step explanation:

We assume your recursive formula is ...

  [tex]a_1=2\\a_n=a_{n-1}^2-2[/tex]

Using this to find a4, we get ...

  [tex]a_2=a_1^2-2=2^2-2=2\\a_3=a_2^2-2=2^2-2=2\\a_4=a_3^2-2=2^2-2=2\\\\\boxed{a_4=2}[/tex]

The correct statement is the point (1, 4) means the 1st term of the sequence is 4. The point (2,3) means the 2nd term and so on

Given the function that represents a given given graph a f(x) = -x + 5

For the first term of the sequence, x = 1. Substitute into the function;

f(1) = -1 + 5

f(1) = 4

This shows that the point (1.4) means the 1st term of the sequence is 4.

For the second term, x = 2

f(2) = -2 + 5

f(2) = 3

This shows that the point (2, 3) means the 2nd term of the sequence is 3.

Answer:

Perimeter =  28·√2 + 24 feet

Step-by-step explanation:

The dimensions of the initial sheet of plywood are;

The length of the sheet of plywood = 25 ft.

The width of the sheet of plywood = 14 ft.

The shape cut from each corner of the sheet of plywood  = A right triangle

The leg length of each of the cut out right triangles = 7 ft.

The number of leg lengths of the right triangle cut from the length side of the initial sheet of plywood = 2

The length of the parallel sides of the remaining hexagonal piece of plywood = Initial length of the plywood - 2 × The leg length of the cut out right triangle

∴ The length of the parallel sides of the remaining hexagonal piece of plywood = 26 ft. - 2 × 7 ft.  = 12 ft.

The other side length of the remaining hexagonal piece of plywood = The hypotenuse side of the cut out right triangle

The hypotenuse side of the cut out right triangle = √((7 ft.)² + (7 ft.)²) = 7·√2 ft.

∴ The other side length of the remaining hexagonal piece of plywood = 7·√2

The number of side lengths in the remaining hexagonal piece of plywood = 4

The perimeter of the remaining hexagonal piece of plywood = 2 × The length of the parallel sides + 4 × The other side lengths

∴ The perimeter of the remaining hexagonal piece of plywood = 2 × 12 ft. + 4 × 7·√2 = (28·√2 + 24) ft.

The perimeter of the remaining hexagonal piece of plywood = (28·√2 + 24) feet

Answer:

The answer is 100ft2 I think

Answer:

A) 24

B) 24

Step-by-step explanation:

A) equilateral triangle means that all sides are equal

so each side is = 24 because the perimeter = 72

72/3= 24

B) 1 side = 24 and they gave you that 10+7h = 24

so h = 2

so hight of triangle = 2

Area = 1/2(b)(h)

so 24(2)(0.5) = 24
