Answer:

a) x = 3

b) 4x

c ) 9x - x

Step-by-step explanation:

a)2x + 4(x -1) = 2 + 4x

2x + 4x - 4 = 2 + 4x

2x[ + 4x [- 4 = 2 [+ 4x

2x + 4x - 4x = 2+4

2x = 6

(Simply both sides by 2)

X = 3

b)25 - x = 15 - (3x + 10)

25 - x = 15 - 3x + 10

25[ - x = [15[ - 3x [+ 10

25 - 15 - 10 = 3x + x

0 = 4x

4x

c)4x = 2x + 2x + 5 (x - x)

4x = 2x + 2x + 5x - 5x

[+4x =[ 2x[ + 2x[ + 5x[ - 5x

2x+ 2x + 5x -5x - 4x

(2x+ 2x + 5x) (-5x - 4x)

9x - x

Answer:

The approximate weight of 1 student back pack is 7.38 pounds.

Step-by-step explanation:

We have to find the unit rate of one back back. All we need to do is divide the 5 backpacks by the number of pounds, so:

36.90 ÷ 5 = 7.38

Answer: The approximate weight of one back pack is 7.38.

Step-by-step explanation: Divide the combined weight by 5. Hope this helps.

Answer:

$3.54

Step-by-step explanation:

$3.79-25% (because you add the 15% + 10%)

which is $3.54

Answer:

$2.90

Step-by-step explanation:

start with original price

$3.79

marked down 15%

3.79 × .15 = .5685 or .57

3.79 - .57 = 3.22 price on shelf

minus 10% coupon

3.22 × .1 = .322 or .32

$3.22 - .32 = $2.90

Answer:

$79.05

Step-by-step explanation:

Simply convert 7% into a decimal which os 0.07.  Multiply 0.07 by 85 and subtract it since it's a tax, which means it's deducted. Which will give you $79.05.

Answer:

170

Step-by-step explanation:

Since the TV is worth $100 initially but has a 70% markup, it means they increased the price by the percent markup

100 x .70 = 70

100 + 70 = $170

The new cost of the TV sold at this store is equal to $170.

Given the following data:

To determine the new cost of the TV sold at this store:

We would calculate the markup price by multiplying the cost price by the markup.

[tex]Markup\;price = \frac{70}{100} \times 100\\\\Markup\;price = 0.7\times 100[/tex]

Markup price = $70

Now, we can find the new cost of the TV:

[tex]New\;cost = Markup\;price + Cost\;price\\\\Total\;cost = 70 + 100[/tex]

Total cost = $170.

From the graph of function,

a. Domain = (-∞, ∞)

b. Range = [-2, -∞)

c. x-intercept = NA

d. y-intercept = (0, -4)

e. f(1) = -3 and f(4) = -4

"It is a set of points which for which the function is well defined."

"It is the set of all possible output values."

"It is a point at which the graph of the function intersects the x-axis or y-axis."

For given example,

From the graph of a function we can observe that, function takes all values of x

So, domain = (-∞, ∞)

The value of the function starts from -2 and it tends towards -∞.

So, Range of f(x) = [-2, -∞)

From the graph of a function we can observe that the graph of a function does not intersect the x-axis.

So, for given function has no x-intercept.

The graph of the function intersects y-axis at (0, -4).

So, y-intercept = (0,-4)

We need to find the value of f(1) and f(4)

From the graph,

for x = 1,

⇒ f(1) = -3

for x = 4,

⇒ f(4) = -4

Therefore, from the graph of function,

a. Domain = (-∞, ∞)

b. Range = [-2, -∞)

c. x-intercept = NA

d. y-intercept = (0, -4)

e. f(1) = -3 and f(4) = -4

Answer:

64°

Step-by-step explanation:

So supplement angles are equal to 180, so first our two angles added together will be 180:

x + x = 180

Now one of these angles is 6 greater than half:

x + (x/2 + 6) = 180

Then we will solve for x:

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

[tex]\frac{3}{2}[/tex]x = 174

x = 116

Plug it back in:

x + (x/2 + 6) = 180

         /\

     x/2 + 6

   (116)/2 + 6

        64

To check:

116 + 64 = 180 ✓

Answer:

it is -3/2

Step-by-step explanation:

use rise/run or y/x to find slope. Start with the lower x value, so the run (movement on the x axis) is 2 so plug that in, rise/2. Fine the rise whish is -3, plug that in and you get -3/2

Answer:

Picture for solition......

The third side of the triangle is 12 units and the measure of the angle θ is 37°.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The third side of the triangle 'a' is calculated by Pythagoras' theorem. Then we have

c² = a² + b²

20² = a² + 16²

400 = a² + 256

a² = 400 - 256

a² = 144

a = 12

Then the value of the angle θ is calculated as,

sin θ = 12 / 20

sin θ = 3 / 5

sin θ = sin 37°

θ = 37°

The third side of the triangle is 12 units and the measure of the angle θ is 37°.

  0.25 < x < 2

Step-by-step explanation:

The quadratic can be factored as ...

  4x^2 -9x +2 < 0

  (4x -1)(x -2) < 0

The factors are zero for x = 1/4 and x = 2. The product of the factors will be negative, satisfying the inequality, for values of x that make one factor positive and the other one negative. Those values of x are between x=1/4 and x=2.

The solution is 1/4 < x < 2.

The graph on the number line has open circles at x=1/4 and x=2, and is shaded between those values.

_____

Additional comment

The circles on the graph are open because those x-values are not part of the solution set.
