Answer:

Dilation factor is 2/3

Step-by-step explanation:

Look at both flat lines (M to S and M' to S') and find their lengths.

M to S = 9 units

M' to S' = 6 units

The triangle has gotten smaller so the dilation factor is a fraction

new/original = 6/9 = .66666666 or 2/3

Dilation factor is 2/3

Answer: year 1948

Step-by-step explanation:

1900 is our t = 0

The population of Greenville can be written as:

G = 4000 + 100*t

the equation for Springfield can be written as:

S = 1000*(1.04)^t

we want to find the value of t that makes S(t) = G(t)

4000 + 100*t = 1000*(1.04)^t

(4000 + 100*t) = 1.04^t

4 + 0.1*t = 1.04^t

now, you can graph both of this equations (left side and right side) and see in wich value of t the graphs intersect eachother, or you also may use different values of t until the values are about the same for both sides, which is the thing i did with the equation:

4 = 1.04^t - 0.1*t

You will find that the correct value is t = 48

So we can assume that in year 1948 the populations will be about the same.

Answer:

(4, -3)

Step-by-step explanation:

The origin is at (0,0). When you move right or left, you change the x-coordinate, or the first coordinate. You moved right which is in the positive direction so now your coordinate is (4,0).

When you move up or down, you change the y-coordinate, or the second coordinate. You moved down which is in the negative direction so your final coordinate is (4, -3).

Answer:

D)The slope is -2/3

Step-by-step explanation:

First, put this equation in slope-intercept form by subtracting 2x on both sides:

2x+3y=6

-2x. -2x

Your equation should be:3y=-2x+6

Then, divide the whole equation by 3 since y has to be by itself

3y=-2x+6

---- ------

3. 3

Your equation should be y=-2/3x+6

Since the slope in slope-intercept form is m in y=mx+b, -2/3×=m

Final answer:D) The slope is -2/3

Answer:

The speed at which the buss made the trip was 45 mph and the train was 57 mph.

Step-by-step explanation:

The average speed is given by:

speed = distance / time

Therefore we can manipulate it to give us the distance:

distance = speed*time

The time distance of each stage of his trip summed must be equal to the total distance of the trip. Since he made a trip in two legs, one by bus that lasted 3 h at a speed of "x" and one that lasted 5 hours at a speed of "x + 12". We have:

420 = 3*x + 5*(x + 12)

3*x + 5*(x + 12) = 420

3*x + 5*x + 60 = 420

8*x = 420 - 60

8*x = 360

x = 45 mph

The speed at which the buss made the trip was 45 mph and the train was 57 mph.

Answer:

45 mph

Step-by-step explanation:

Answer:x>7 or x ≤ -3

Solving the 1st inequality

-6x +14 < -28 --------------- (Collect like terms)

-6x < -28 - 14

-6x < - 42 -------------------- (Divide both sides by -6)

Note: If you decide an inequality expression by a negative value, the inequality sign changes)

-6x/-6 > -42/-6

x > 7

Solving the 2nd inequality

9x + 15 ≤ −12 ----------- (Collect like terms)

9x ≤ −12 - 15

9x ≤ −27 ------------------(Divide both sides by 9)

9

9x/9 ≤ −27/9

x ≤ -3

Bring both results together, we get

x>7 or x ≤ -3

The final result is complex (i.e. can't be combined together).

Step-by-step explanation:

Answer:

x> 7 OR x ≤−3

Step-by-step explanation:

−6x+14<−28 OR 9x+15≤−12

Solve them separately and then put back together

−6x+14<−28

Subtract 14 from each side

-6x +14-14 <-28-14

-6x <-42

Divide each side by -6, remembering to flip the inequality

-6x/-6 > -42/-6

x> 7

9x+15≤−12

Subtract 15 from each side

9x +15-15 ≤−12 -15

9x ≤−27

Divide each side by 9

9x/9 ≤−27/9

x ≤−3

Answer:

-23

Step-by-step explanation:

x = -5 lies in the last piece

h(-5) = 4(-5) - 3

= -20 - 3

= -23

Step-by-step explanation:

Step 1:  Find which piece-wise function it is in

Equation 1 → x < -7

Let x = -5 → (-5) < -7 ← False

Equation 2 → -7 ≤ x < -5

Let x = -5 → -7 ≤ (-5) < -5 ← False

Equation 3 → x ≥ -5

Let x = -5 → (-5) ≥ -5 ← True

Step 2:  Find the value of h(-5)

[tex]h(-5) = 4x - 3[/tex]

[tex]h(-5) = 4(-5) - 3[/tex]

[tex]h(-5) = -20 - 3[/tex]

[tex]h(-5) = -23[/tex]

Answer:  [tex]h(-5) = -23[/tex]

Answer:

  6.75

Step-by-step explanation:

The shaded area amounts to two congruent equilateral triangles. Each has a side length of 2(1 in)cos(30°) = √3 in.

The height of an equilateral triangle with side length √3 is ...

  height = (√3 in)sin(60°) = 3/2 in

Then the area of the two equilateral triangles is ...

  A = bh = (√3 in)(3/2 in) = 3√3/2 in^2

The square of the numerical value of the area is ...

  A^2 = ((3/2)(√3))^2 = 27/4 = 6.75

The square of the shaded area is 6.75.

i cant really plot them for you but i will help explain how to plot them.

the x-axis is the horizontal plane on the graph. the y-axis is the vertical plane on the graph. every coordinate has both a x and y point.

for you the x would be -8 and the y would be 7. first, you would go accross the x-axis to -8 and then go up to positive seven. you would be in the fourth quadrent in the graph. then  you would do the same to the other pair. remember, (x,y)

Answer:

x = 3      x = -5

Step-by-step explanation:

2|x+1|=8

Divide each side by 2

2/2|x+1|=8/2

|x+1| = 4

There are two solutions to an absolute value, one positive and one negative

x+1 = 4            x+1 = -4

Subtract 1 from each side

x+1 -1 = 4-1         x+1-1 = -4-1

x = 3                     x = -5

Answer:

x=3 and -5

Step-by-step explanation:

to start with when you work with equations there will be two answers, no solution set or the answer will be 0. in this case there are two answers.

2/x+1/=8(first you remove all the things that are extra to the equation)

2          2

/x+1/=4 in this case it has two answers because 4 is greater than 0.

so you remove the bracket.

x+1=4                               or                              x+1=-4

x=4-1                                                                  x=-4-1      

x=3                                                                    x=-5

Answer:

Option (3). $1500

Step-by-step explanation:

Cost price of the jukebox = $9400

Down payment made by the diner = $1000

Diner agreed to pay the rest amount by $275 per month for 36 months

Total amount to be paid by the diner = Down payment + monthly payments

                                                              = 1000 + 275×36

                                                              = 1000 + 9900

                                                              = $10900

Finance charge = 10900 - 9400

                          = $1500

Therefore, option (3). 1500 will be the answer.

Answer:

430

Step-by-step explanation:

Answer: 430

Step-by-step explanation:

Step-by-step explanation:

m∠1 = 180-100 = 80

m∠2 = 180-150 = 30

m∠3 = 180-(80+30) = 180 - 110 = 70

using the law of sine :

AC/sin(m∠2) = 5/sin(m∠3) ⇒ AC = sin(m∠2)*(5/sin(m∠3)) = sin(30)×(5÷sin(70))

=2.66044443119

CB/sin(m∠1) = 5/sin(m∠3) ⇒ CB = sin(m∠1)*(5/sin(m∠3)) ⇒ CB = sin(80)×(5÷sin(70)) = 5.240052604588

Answer:

91.2

Step-by-step explanation:

If there is 57 ounces in 5 boxes and you divide 57 by 5 you'll get 11.4. After that you should times 11.4 by 8 to get 91.2 ounces

Answer:

91.2 ounces

Step-by-step explanation:

Let's make a proportion using this setup:

ounces/boxes=ounces/boxes

There are 57 ounces in 5 boxes, and x ounces in 8 boxes.

57 ounces/5 boxes= x ounces/8 boxes

57/5=x/8

Now we have to solve for x. x and 8 are being divided. To undo this, multiply both sides by 8, because multiplication is the opposite of division.

8*57/5=x/8*8

The 8s on the right will cancel, so we are left with:

8*57/5=x

8*11.4=x

91.2=x

There are 91.2 ounces in 8 boxes

Answer:

there are infinite integers.
