Answer:

Step-by-step explanation:

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put the coordinates of the points (-3, 4) and (-5, -6) to the formula of a slope:

[tex]m=\dfrac{-6-4}{-5-(-3)}=\dfrac{-10}{-2}=5[/tex]

Answer:

True

Step-by-step explanation:

2(4)+(3)=11

8+3=11

11=11

(3)=(4)-1

3=4-1

3=3

all you have to do is substitute 4 for you x-values, and substitute 3 for your y-values, and then solve the equations.

True. X= 4 and Y= 3.

2(4) + 3 = 11

Answer:

80.73 each month

Step-by-step explanation:

The original price of the computer is $598. It is offered for 25% off. This means you pay 75% of the original price or 0.75(598) = 448.5. The sales price is $448.50. You will pay 8% tax on this price. This means you'll pay 100% of the price plus 8% more. So this is 1.08(448.5) = 484.38.

In total you pay 484.38 over 6 months. This means each month you pay 484.38/6 = 80.73.

Answer:

{y,x} = {-6,-2}

Step-by-step explanation:

/ Solve equation [2] for the variable  y  

 [2]    y = 2x - 2

// Plug this in for variable  y  in equation [1]

  [1]    (2x-2) - x = -4

  [1]    x = -2

// Solve equation [1] for the variable  x  

  [1]    x = - 2

// By now we know this much :

   y = 2x-2

   x = -2

// Use the  x  value to solve for  y  

   y = 2(-2)-2 = -6

Answer:

The radius of the circle is [tex]24\ hm[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

In this problem we have

[tex]C=150.7968\ hm[/tex]

[tex]\pi=3.1416[/tex]

substitute and solve for r

[tex]150.7968=2(3.1416)r[/tex]

[tex]r=150.7968/(2(3.1416))=24\ hm[/tex]

Answer:

Answer:

all reals, except at x=0

Step-by-step explanation:

because x is in the denominator, x cannot equal 0

For this case we have a function of the form [tex]y = f (x),[/tex]where:

[tex]f (x) = \sqrt {\frac {3} {x}}[/tex]

we must find the domain of the function.

The domain is given by all the values for which the function is defined.

Note that "x" is not defined for negative numbers or for zero. Then x can only take strict higher values to zero.

Domain: {x | x> 0}

Answer:

Domain: {x | x> 0}

Answer:

[tex]\large\boxed{\text{The slope}\ m=3}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the equation of a line in the standard form:

[tex]12x-4y=3[/tex]

Convert to the slope-intercept form:

[tex]12x-4y=3[/tex]         subtract 12x from both sides

[tex]-4y=-12x+3[/tex]        divide both sides by (-4)

[tex]y=\dfrac{-12}{-4}x+\dfrac{3}{-4}\\\\y=3x-\dfrac{3}{4}[/tex]

Answer:  The required slope of the given line is 3.

Step-by-step explanation:  Given that Helaine graphed the following equation :

[tex]12x-4y=3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We are to find the slope of the line.

We know that

the slope-intercept form of a straight line is given by

[tex]y=mx+c,[/tex] where m is the slope of the line.

From equation (i), we have

[tex]12x-4y=3\\\\\Rightarrow 4y=12x-3\\\\\Rightarrow y=\dfrac{12x-3}{4}\\\\\\\Rightarrow y=3x-\dfrac{3}{4}.[/tex]

Comparing with the slope-intercept form, we get

slope, m = 3.

Thus, the required slope of the given line is 3.

The correct statement about rhombuses and parallelograms is that rhombuses always have four equal sides while parallelograms sometimes do not. The other options are not true for rhombuses and parallelograms.

The correct statement about rhombuses and parallelograms is option A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not. A rhombus, by definition, is a four-sided figure with all sides having equal length while a parallelogram is a four-sided figure with only opposite sides being equal.

Options B, C, and D are incorrect. Rhombuses do not always have four right angles; that is characteristic of a rectangle. Parallelograms always have opposite sides equal and parallel, so C and D are not true.

https://brainly.com/question/35882736

The correct answer is option (A).The true statement is that rhombuses always have four equal sides, while parallelograms sometimes do not. This characteristic is a key distinction between rhombuses and general parallelograms. The other statements about angles and sides are incorrect regarding rhombuses and parallelograms.

To determine which statement about rhombuses and parallelograms is true, we need to understand their definitions and properties:

Given these definitions, let's evaluate each statement:

Option A) is the true statement as rhombuses always have four equal sides and parallelograms sometimes do not.

Answer:

-2

Step-by-step explanation:

We have been given a function f(x)=\frac{-2x}{x+1} and we are asked to find the horizontal asymptote of our given function.

Recalling the rules for a horizontal asymptote:

1. If the numerator and denominator have equal degree, the horizontal asymptote will be the ratio of the leading coefficients.

2. If the polynomial of denominator has larger degree than the numerator, then the horizontal asymptote will be the x-axis or y=0.

3. If the polynomial of numerator has larger degree than denominator, then the function has no horizontal asymptote.

Here, the numerator and denominator are of the same degree. So the horizontal asymptote will be the ratio of the coefficients.

Horizontal asymptote = [tex]-\frac{2}{1}[/tex] = -2

Step-by-step explanation:

5x2=10

9x10=90

90+10=100

Answer:

60%

Step-by-step explanation:

p/100 = 18/30

Multiply each side by 100

p/100 *100 = 18/30 *100

p = 60

18 is 60 percent of 30

The number 18 out of the number 30 is 60 percent.

We need to find what percent is 18 out of 30.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here, 18/30

= 9/15

= 3/5

= 0.6

In percentage 0.6×100

= 60%

Therefore, the number 18 out of the number 30 is 60 percent.

Answer:

Step-by-step explanation: just multiply

The ratio of the number of gallons of oil to the number of gallons of solvent is 2:3.

The ratio of the number of gallons of oil to the number of gallons of solvent can be determined by subtracting the number of gallons of oil from the total volume of the mixture and then dividing by the number of gallons of solvent. In this case, the total volume of the mixture is 45 gallons and the number of gallons of oil is 18. So, the number of gallons of solvent is 45 - 18 = 27. Therefore, the ratio of the number of gallons of oil to the number of gallons of solvent is 18:27, which can be simplified to 2:3.

Answer:

Step-by-step explanation:

Hello, you need to divide that form into two forms: a triangle and a square.

For square:

A1 = 7in X 7in = 49 in2

For triangle:

A2 = [(7in) X (11in-7in)]/2 = 10.5 in2

So, the total area is the sum of A1+A2

Area = 59.5 in2

Answer:

the correct answer is 3x-36

It’s 140 degrees. The angles are congruent from their pair.

a is 35 because vertical angles

b is 55 because triangle sum

90(right angle)+35(a)+b=180

180-90=90-90+35+b

90=35+b

-35 -35

55=b

c is 110 because linear pairs

Step-by-step explanation:

Let

x------> total distance of a trip

y-------> the price of a trip

step 1

Find the slope

Let

[tex]A(70,114.1),B(100,118)[/tex]

[tex]m=\frac{(118-114.1)}{100-70}=0.13\frac{\$}{m}[/tex]

step 2

Find the equation of the line into point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=0.13[/tex]

[tex]A(70,114.1)[/tex]

substitute

[tex]y-114.1=0.13(x-70)[/tex]

[tex]y=0.13x-9.1+114.1[/tex]

[tex]y=0.13x+105[/tex]

step 3

For [tex]y=\$131[/tex]

Find the value of x

substitute in the linear equation and solve for x

[tex]131=0.13x+105[/tex]

Both Jenna and Juan are INCORRECT.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1 job / 2 hours + 1 job / 1.5 hours = 1 job / x  When they work together.

1/2 + 1/1.5 = 1/x                Basic Equation. Change to decimal form

0.5 + 0.6666 = 1/x          Add like terms on the left

1.1666666 = 1/x              Multiply by x on both sides.

1.1666667 x = 1               Divide by 1.16666667

x = 1 / 1.166667               Do the division.

x = 0.8571428              

x = 6/7 of an hour.

This kind of question will always produce an answer that is less than the smallest number.

So the answer must be smaller than 2 hours or 1.5 hours.

Answer:

see below

Step-by-step explanation:

2.5 = 2 5/10 = 250%

40% = .40 = 40/100 = 4/10 =2/5

220% = 220/100 = 2 20/100 = 2 2/10 = 2 1/5

1/4 = 25/100 = 25%

4% = 4/100 = .04

2.5 =2/5

0.004 =4%

220% = 2 1/5

1/4 =25%
