Helpppppp meeee plzzzz

Step-by-step explanation:

substitute the value of y in terms of x

-2x - 3(6x-11)= -7

-2x - 18x+ 33=-7

-20x= -40

x = -40/-20

x= 2

substitute x=2 in first equation

y= 12-11

y= 1

$60 * 3% = $1.80

y = 1.80x + $60

12 * 2 = 24

24 = x

y = 1.80(24) + $60

y = $43.20 + $60

y = $103.20

Answer:

B) Rotation

Step-by-step explanation:

The only difference between functions f(x) and g(x) is the slope. To get from f(x)=4x+1 to g(x)=2x+1, you would need to rotate slightly clockwise about point (0,1) - the y-intercept. This would make the graph less steep (2x is less steep than 4x) while still retaining the (0,1) y intercept.

Answer:

rotation

Step-by-step explanation:

Yes, Xavier have enough track for a train with 15 cars because the cars will take up 2.4 meters, leaving them with an extra .1 meters of length.

A unit conversion expresses the same property as a different unit of measurement. For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometres, or feet, or any other measure of length.

Given that, Xavier is building a model train. He has enough track for a train that is 2.5 meters long. We need to find if Javier have enough track for a train with 15 cars or not if each car will be 16 centimetres long

The length of each car is 16 cm

Therefore, length of 15 cars = 16 × 15 = 240 cm

Converting the units,

240 cm = 2.4 m

Since, The train is 2.5 m long, and he has enough track for it.

Hence, Yes, Xavier have enough track for a train with 15 cars because the cars will take up 2.4 meters, leaving them with an extra .1 meters of length.

Answer:

Step-by-step explanation:

1. it is an equilateral triangle.

let  base=2x

let h be the height from centre.

h/8=sin 30=1/2

h=1/2×8=4

so total height=8+4=12

again  x/8=cos 60

x=(√3/2)×8=4√3

Base=2x=2×4√3=8√3

area of triangle=1/2×8√3×12=48√3 sq. units.

2.

one diagonal=3+8=11

second diagonal=5+5=10

Answer:

8 kilometers per hour.

Step-by-step explanation:

1-If you multiply the hours of the trip back (which is 4 hours) and the kilometer per hour (6 km/h) you will get 24.

2-Do the same thing with the trip there and you will get 3 hours multiplied by *blank* equals 24.

3-the blank is 8 kilometers per hour. And I wrote equal 24 to mean that the distance to Guam was 24 kilometers.

Answer:

-5

Step-by-step explanation:

Score in first round = +15

Scores lost in second round = -30

Score in third round = 10

Total points = 15+-30+10= -5

Answer:

10 + 10 + 10 = 30

5 + 5 + 10 = 20

4 + 4 + 5 = 13

5 + 19 x 2 = 43

Step-by-step explanation:

Pair of shoes = 10

Boy = 5

2 snow cones = 4

One shoe = 5

boy + 2 snow cones + a pair of shoes (his feet) x one snow cone = 43

I really hope this helps!

Answer:

30/3=10

two shoes is 10

20-10=10

10/2=5

each person is 5

13-5=8

8/2=4

Two cones is 4

2 (only 1 cone) x 19(two cones is 4 + each person 5 =9. 9 + 10 because of the two shoes = 19) =  38

38+5(only 1 shoe) = 43

Answer:

Option A. 56

Step-by-step explanation:

The question talks about chosing 5 presenters out of 8 presenter.

This can be achieved b using the following formula:

nCr = n! /r! (n–r)!

n = 8

r = 5

8C5 = 8! / 5! (8 – 5)!

8C5 = 8! / 5! 3!

8C5 = (8 x 7 x 6) / (3 x 2 x 1)

8C5 = 56

Therefore, there are 56 ways in which the teacher can chose the presenters.

Answer:

24 fishes

Step-by-step explanation:

If for 1 inch of fish corresponds 12 square inches of  surface area, then for 2 inches correspond 24 square inches. Given that each fish is 2 inches, then for 1 fish 24 square inches of  surface area is needed. To know how many fish you can put in your tank, we need to solve the following proportion:

1 fish / x fish = 24 square inches / 576 square inches

x = 576/24

x = 24 fishes

The measure of the angle is ∠ADB=60

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°

Given here: ∠A =∠B=60

By triangle sum property we must have ∠A +∠B+∠D=180

                                                                                 ∠D=60

Thus the triangle must be an equilateral triangle with all its angles equal to 60

Hence, The measure of the angle is ∠ADB=60
