The difference between a and b is 12. The number a is 5 more than 3 times the number b. Which of the following pairs of equations could be used to find the values of aand b?

Answer:

Only point C. (9,4)

Step-by-step explanation:

To check if the points are inside the region of the inequalities, we just need to use the values of the point in each inequation, and if the point satisfy all inequations, the point is inside the region.

point A = (1,8): s = 1 and t = 8

first inequation: s<24 - 0.66t

1 < 24 - 0.66*8

1 < 18.72 (true)

second inequation: s>12 - t

1 > 12 - 8

1 > 4 (false)

So point A is not inside the region.

point B = (-9,21): s = -9 and t = 21

As we can see from the fourth inequation, the s value needs to be greater than 0, and point B has s negative, so point B is not inside the region.

point C = (9,4): s = 9 and t = 4

first inequation: s<24 - 0.66t

9 < 24 - 0.66*4

9 < 21.36 (true)

second inequation: s>12 - t

9 > 12 - 4

9 > 8 (true)

third inequation: s< 30 - t

9 < 30 - 4

9 < 26 (true)

fourth inequation: s>0

9 > 0 (true)

fifth inequation: t>0

4 > 0 (true)

As all conditions are true, point C is inside the region.

point D = (30,10): s = 30 and t = 10

first inequation: s<24 - 0.66t

30 < 24 - 0.66*10

30 < 17.4 (false)

So point D is not inside the region.

Answer:

Because there are 24 ducks total and they are separated equally into three categories, we can figure out that there are 24 / 3 = 8 ducks of each color. This makes the probability of pulling a red/blue duck would be (8*2)/24 or 16/24. If we want this to be a percentage we can just solve 16/24*100 and it will give us 66.66...%

  reflection, then rotation, then translation

Step-by-step explanation:

Read the problem statement. It tells you the sequence:

Triangle A B C is reflected across B C to form triangle A prime B C. Triangle A prime B C is then rotated about point A to form A prime B prime C prime. Triangle A prime B prime C prime is then shifted to the right to form A double-prime B double-prime C double-prime.

Answer:

When you change the inequality as the formula of y>ax+b, it is over the boundary line. While the formula is y<ax+b, it is below the boundary line. So we can get the answer is D.

Answer:

118

Step-by-step explanation:

The sum of the angles is 180 degrees

(3x + 13) + (x-8) +x = 180

Combine like terms

5x +5 = 180

Subtract 5 from each side

5x+5-5= 180-5

5x =175

Divide by 5

5x/5 = 175/5

x = 35

We want to find angle A

3x+13

3(35)+13

Answer:

1)  y = -3x + 9

2) y = -3/4x + 6

3) y = x - 5

Step-by-step explanation:

1) 3x + y - 7 = 2

            +7   +7

        3x + y = 9

       -3x        -3x

                y = -3x + 9

2) 3x + 4y = 24

  -3x           -3x

          4y = -3x + 24

          4        4      4

          y = -3/4x + 6

3) x - y = 5

  -x        -x

      -y = -x + 5

       -1     -1   -1

        y = x - 5

Answer: B, but technically, all of them are correct except C.

Step-by-step explanation:

First, you fill in 1 for n:

= 2 x 4(1)

= 2 x 4

= 8

Next, I filled in 4 for n:

= 2 x 4(4)

= 2 x 16

= 32

Then, I filled in 8 for n:

= 2 x 4(8)

= 2 x 32

= 64

You can already figure this one out, and the answer is B.

Answer:

all are correct except the third choice.

The amount in equation is 5d + 3h + 8s = 231.

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Given:

Jeremy had 5 Roosevelt dimes,

3 Kennedy half dollars,

and 8 silver dollars in his coin.

Total amount = $231

As, let d be the collector value of a dime

let h be the collector value of a half dollar

let s be the collector value of a silver dollar

Now, to represent the amount in equation

5d + 3h + 8s = 231
