I need help trying to solve this world problem

Answer:

x = 1

Step-by-step explanation:

Given

[tex]\frac{2x^2-7x-4}{x^2-5x+4}[/tex] ← factor numerator and denominator

= [tex]\frac{(x-4)(2x+1)}{(x-4)(x-1)}[/tex] ← cancel (x - 4) on numerator/ denominator

= [tex]\frac{2x+1}{x-1}[/tex]

The denominator of the rational expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.

x - 1 = 0 ⇒ x = 1 ← excluded value

Answer:

29.70

Step-by-step explanation:

Add up purchases 4.35+8.20+12.45+2.5=27.50

calc sales tax 27.50 x .08=$2.20

27.50+2.20=29.70

The solution is, 29.70 is the total amount Charlotte will pay for her purchases if there is an 8% sales tax.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

given that.

from the given data, we get,

mouth wash = 4.35

detergent = 8.20

paper towels = 12.45

dish soap = 2.50

so, we get,

as total,

Add up purchases 4.35+8.20+12.45+2.5=27.50

now, we get,

calc sales tax 27.50 x .08=$2.20

so, we have,

27.50+2.20=29.70

Hence, The solution is, 29.70 is the total amount Charlotte will pay for her purchases if there is an 8% sales tax.

A, C and d are correct 9,27 and 30

Answer:

since A is getting smaller it cant be the last 2, so its either 1/2 or 3/4 and a 1/2 dilation would be wayy smaller than that. so I'm thinking its 3/4

Answer:

23 degrees

Step-by-step explanation:

First add a diameter. The triangle \pink{ABD}ABDstart color #ff00af, A, B, D, end color #ff00af is isosceles as \pink{AB}ABstart color #ff00af, A, B, end color #ff00af and \pink{BD}BDstart color #ff00af, B, D, end color #ff00af are radii, so must be equal. Therefore, \pink{\angle{BAD}}∠BADstart color #ff00af, angle, B, A, D, end color #ff00af and \orange{\angle{ADB}}∠ADBstart color #ffa500, angle, A, D, B, end color #ffa500 are equal. Since, the angles in a triangle sum to 180^\circ180   180∠ABD+∠BAD+∠ADB∠ABD+2⋅∠ADB∠ABD===180∘180∘180∘−2⋅∠ADB

So, \blue{\angle{ABE}} = 2 \cdot \orange{\angle{ADB}}∠ABE=2⋅∠ADBstart color #6495ed, angle, A, B, E, end color #6495ed, equals, 2, dot, start color #ffa500, angle, A, D, B, end color #ffa500. We can also create an isosceles triangle, \pink{BCD}BCDstart color #ff00af, B, C, D, end color #ff00af.Using the same argument we can find that, \blue{\angle{CBE}} = 2 \cdot \orange{\angle{CDB}}∠CBE=2⋅∠CDBstart color #6495ed, angle, C, B, E, end color #6495ed, equals, 2, dot, start color #ffa500, angle, C, D, B, end color #ffa500.∠ABC=∠ABE−∠CBEstart color #6495ed, angle, A, B, C, end color #6495ed, equals, start color #6495ed, angle, A, B, E, end color #6495ed, minus, start color #6495ed, angle, C, B, E, end color #6495ed

\orange{\angle{ADC}} = \orange{\angle{ADE}} - \orange{\angle{CDE}}∠ADC=∠ADE−∠CDEstart color #ffa500, angle, A, D, C, end color #ffa500, equals, start color #ffa500, angle, A, D, E, end color #ffa500, minus, start color #ffa500, angle, C, D, E, end color #ffa500

Hint #1010 / 11

Since \blue{\angle{ABE}} = 2 \cdot \orange{\angle{ADE}}∠ABE=2⋅∠ADEstart color #6495ed, angle, A, B, E, end color #6495ed, equals, 2, dot, start color #ffa500, angle, A, D, E, end color #ffa500 and \blue{\angle{CBE}} = 2 \cdot \orange{\angle{CDE}}∠CBE=2⋅∠CDEstart color #6495ed, angle, C, B, E, end color #6495ed, equals, 2, dot, start color #ffa500, angle, C, D, E, end color #ffa500, \blue{\angle{ABC}} = 2 \cdot \orange{\angle{ADC}}∠ABC=2⋅∠ADCstart color #6495ed, angle, A, B, C, end color #6495ed, equals, 2, dot, start color #ffa500, angle, A, D, C, end color #ffa500

Hint #1111 / 11

Please solve the third question and answer in the comments and I will tell you if you are correct.

Step-by-step explanation:

1)Find the solution of the following system of equations; express the answer as a coordinate pair (x,y):

y = x + 3         subtract from the bottom  and solve for x

y = -2x - 3    

y - y = x - (-2x) + 3 - (-3)

  0  =  3x + 6

 -6  =  3x

-2  =  x

 y = x + 3     y = -2 + 3     y = 1      (-2, 1)

2)Find the solution of the following system of equations; express the

answer as a coordinate pair (x,y):

y = 2x + 1              subtract from the bottom  and solve for x

y = x/2 + 4

y-y = 2x - 1/2 x +1 - 4

 0  = x(2-1/2) - 3

 3  = 1.5x

 2  = x          y = 2x + 1      y = 2(2) + 1       y = 5       (2, 5)

3) Find the solution of the following system of equations; express the

answer as a coordinate pair (x,y):

y = -3x + 6          subtract from the bottom  and solve for x

y= -1/2x+1            

y-y = x(-3 - (-1/2)) + (6 - 1)       follow the examples above

It is true

you just solve for x on the left side first then the same on the right they should be the same

i think this is how i would do it

Answer:

The y-intercept is y = -$150

Step-by-step explanation:

We know that:

Each necklace is sold for $8.

The total cost for Michelle is $150.

The profit equation is:

Profit = Revenue - Cost.

We already know that Cost = $150

The revenue will depend on x, the number of necklaces sold, so if each one costs $8, and she sells x of them, the revenue is:

Revenue = $8*x

Then the profit, as a function of x, is:

y = P(x) = $8*x - $150

Where y represents the profit.

Now we want to find the y-intercept of the profit equation, where the y-intercept is the y-value when we use x = 0

Then the y-intercept is:

P(0) = $8*0 - $150 = -$150

Also the graph of the equation can be seen below, where you need to remember that x can be any value in [0, 200] and only can be an integer.

So you only need to graph the line between x = 0 and x = 200.

Answer:

y= 327(0.85)^t

Step-by-step explanation:

Given data

Initial Population= 327

Increase= 15%

The model for an exponential function is represented as

y= P(1-r)^t

Substitute

y=327(1-0.15)^t

y= 327(0.85)^t

Answer:

  5000π mm³ ≈ 15,700 mm³

Step-by-step explanation:

The volume of the cylinder is given by the formula ...

  V = πr²h

For the given radius and height, the volume is ...

  V = π(10 mm)²(50 mm) = 5000π mm³

Using 3.14 for π, the volume is ...

  5000(3.14) mm³ = 15,700 mm³

Step-by-step explanation:

Answer: 24 cm²

Step-by-step explanation:

To find the area, first find the width of the rectangle.

Perimeter = (2 * Length) + (2 * Width)

20 = (2 * 6) + (2w)

20 = 12 + 2w

2w = 20 - 12

w = 8/2

w = 4 centimeters

Area = Length * Width

= 6 * 4

= 24 cm²

Answer:

(- 3, 1 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

([tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = K(- 1, 5) and (x₂, y₂ ) = M(- 5, - 3) , then

midpoint = ( [tex]\frac{-1-5}{2}[/tex] , [tex]\frac{5-3}{2}[/tex] ) = ( [tex]\frac{-6}{2}[/tex] , [tex]\frac{2}{2}[/tex] ) = (- 3, 1 )
