Answer:

$71.40

Step-by-step explanation:

Before Tax Price: $68.00

Sale Tax: 5.00% or $3.40

After Tax Price: $71.40

Answer:

71.40

Step-by-step explanation:

Sales tax = 5% of 68

              [tex]=\frac{5}{100}*68\\\\=\frac{340}{100}\\\\= 3.40[/tex]

Sales tax = $ 3.40

Total cost = 68 + 3.40 = $ 71.40

All 3 sides of the triangle are identical so each interior angle is 60 degrees.

7x + 4 = 60

Subtract 4 from both sides:

7x = 56

Divide both sides by 7:

x = 8

Answer:

y = 8x

Step-by-step explanation:

Given that :

Ornanment are packed in boxes

Number of ornament per box = 8

x = number of boxes packed

y = Number of ornaments

Number of Ornanments packed = (Number ornaments per box * number of boxes packed

y = 8 * x

y = 8x

Answer:

x=10

Step-by-step explanation:

Pull out like factors :

  -9x + 90  =   -9 • (x - 10)

Equations which are never true:

2.1      Solve :    -9   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x-10 = 0

Add  10  to both sides of the equation :

                     x = 10

Answer:

  p (-1)  = -156

Step-by-step explanation:

Explanation:-

Given polynomial

           p(x)=7x³ -6x²+39x-104

Put x=-1

          p (-1)    = 7 ( -1 )³ - 6 ( -1 )² + 39 (-1 ) - 104

                     = - 7 - 6 - 39 - 104

          p (-1)  = -156

Answer:

y = -2x + 7

Step-by-step explanation:

to write the equation to this problem, we need to find the the y intercept, or the point where the line intersects the Y axis

a slope of -2 means that for every x unit in the positive x direction (right) two y units are moved in the negative Y direction (downward)

so if we subtract (go to the left) 1x that means we would also have to add (go up) 2y, which would leave us at the point (0,7)

now, an equation for a line is written as Y = MX + B

M = slope

B = y intercept

our slope, as we said before, is -2, and we found the Y intercept, 7, so now we can construct our equation

y = -2x + 7

Answer:

y= -2x + 7

Step-by-step explanation:

Answer:

y = [tex]-\frac{4}{3}[/tex]x + 6

Step-by-step explanation:

y = mx + b

m: slope

b: y-intercept

y-intercept point on the graph is (0, 6) because it's the point that's on the y-axis.

Therefore, y-intercept is 6.

Slope: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Point A: (0, 6)

Point B: (4, -2)

Slope (m) = [tex]\frac{-2 - 6}{4 - -2}[/tex]

[tex]m = \frac{-2 - 6}{4 +2}[/tex]

[tex]m = \frac{-8}{6}[/tex]

[tex]m = -\frac{4}{3}[/tex]

y = [tex]-\frac{4}{3}[/tex]x + 6

Answer: See explanation

Step-by-step explanation:

The best player on a basketball team makes 95​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 95% × 40

= 95/100 × 40

= 0.95 × 40

= 38

The​ second-best player makes 90​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 90% × 40

= 90/100 × 40

= 0.90 × 40

= 36

The​ third-best player makes 80​% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:

= 80% × 40

= 80/100 × 40

= 0.80 × 40

= 32

Answer:

Step-by-step explanation:

The interior angle of the m-gon is ...

  m-interior = 180 -360/m

The exterior angle of the k-gon is ...

  k-exterior = 360/k

The required relationships are ...

  m = 3k

  m-interior = 14/3(k-exterior)

Substituting for m, we can write the latter relation as ...

  (180 -360/(3k)) = 14/3(360/k)

Multiplying by 3k/180, we have ...

  3k -2 = 28

  k = (28 +2)/3 = 10

The values of k and m are 10 and 30, respectively.

_____

Check

The interior angle of the m-gon is 180 -360/30 = 168 degrees.

The exterior angle of the k-gon is 360/10 = 36 degrees.

The angle ratio is 168/36 = 14/3 as required.

Answer:

A negative integer

Step-by-step explanation:

3x - 2(5x+12) - 32 = 0

3x - 10x - 24 - 32 = 0

-7x -56 = 0

-7x = 56, x = -8

y = 5(-8) + 12, y = -28

Answer:

1) x-intercepts are at -3 and -4

2) x-intercepts are at 5/3 and 2

Step-by-step explanation:

1) y = -x^2 - 7x - 12  is -(x + 3) (x + 4)

2) y = 3x^2 + 11x + 10  is (3x + 5) (x + 2)

Answer:

24 Square Feet.

Step-by-step explanation:

Answer:

A) -2.5

Step-by-step explanation:

You have to plug the x-value into the function.

f(x) = (1/2)x - 1

f(x) = 1/2(-3) - 1

f(x) = (-3/2) - 1

f(x) = -1.5-1

f(x) = -2.5
