Answer:

17-3-5=9???

Step-by-step explanation:

The number expression is 9 = 17 - 3 - 5 if Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have:

"Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.’’

Let x be the total number of basketballs that can be used.

x = 17 - 3(broken) - 5(need to pump)

x = 17 - 3 - 5

x = 17 - 8

x = 9

9 = 17 - 3 - 5

Thus, the number expression is 9 = 17 - 3 - 5 if Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.

Answer:

Step-by-step explanation:

Answer:x = -0.1290322581

Step-by-step explanation:

Simplifying

9x + -4(1 + 10x) = 0

9x + (1 * -4 + 10x * -4) = 0

9x + (-4 + -40x) = 0

Reorder the terms:

-4 + 9x + -40x = 0

Combine like terms: 9x + -40x = -31x

-4 + -31x = 0

Solving

-4 + -31x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + -31x = 0 + 4

Combine like terms: -4 + 4 = 0

0 + -31x = 0 + 4

-31x = 0 + 4

Combine like terms: 0 + 4 = 4

-31x = 4

Divide each side by '-31'.

x = -0.1290322581

Answer:

The degrees of freedom are

                         ν₁ = n₁ -1 = 13 -1 = 12

                          ν₂= n₂-1 = 13 -1 =12

Step-by-step explanation:

Step(i):-

Given size 'n' = 13

size of sample of X score     n₁ = 13

size of sample of Y score     n₂ = 13

The degrees of freedom are

                         ν₁ = n₁ -1 = 13 -1 = 12

                          ν₂= n₂-1 = 13 -1 =12

Answer:

The probability is 1/51

Step-by-step explanation:

In a deck of cards, there are 52 cards

one king of spades and one king of club

If the first is a king of club, after drawing it, the number of cards that we will have left will be 52-1 = 51 cards

So the probability that the second is a king of spades is the number of king of spades/number of remaining cards

Mathematically that will be 1/51

2 3 x - 6

Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=3x2+9 f - 1 ( x ) = 3 x 2 + 9 is the inverse of f(x)=23x−6 f ( x ) = 2 3 x - 6

To have only one solution the two lines must have different slopes, then the correct option is:

y = x + 4.

We want our system to have exactly one solution, so the two lines must have different slopes.

The already graphed line s:

y = 2x + 4

Notice that the slope is 2, then we need to select the option with an slope different than 2, which is the last option:

y = x + 4

If we graph that line, the system will have only one solution.

Step-by-step explanation:

In geometry, an isosceles triangle is a triangle that has two sides of equal length.   An acute angle is less than 90 degrees. Have a great day!

Answer: 5 inches

Step-by-step explanation:

Perpendicular bisectors must be split directly in half, as they are *bi*sectors, meaning "*two* sections"

Perpendicular means when two angles come together to create a 90° angle

This means that angle BDA is also a 90 degree angle

Since line AC is the line segment split by the perpendicular line segment BD, then you can assume that it is the only 8 inch line, according to multiple laws of geometry. This indicates that segment BC and segment BA must be congruent.

Answer:

y = 1/8x + 25/8

Step-by-step explanation:

Answer:

x = 13

y = 7

Step-by-step explanation:

✔️Recall that sum of the interior angles of a ∆ = 180°

Therefore:

(3x - 3) + (4x + 20) + (7x - 19) = 180° (sum of ∆)

Solve for x

3x - 3 + 4x + 20 + 7x - 19 = 180

14x - 2 = 180

Add 2 to both sides

14x = 182

Divide both sides by 14

✅x = 13

✔️Recall also that an isosceles has two equal sides, therefore:

8y - 7 = 5x - 16

Plug in the value of x

8y - 7 = 5(13) - 16

8y - 7 = 65 - 16

8y - 7 = 49

Add 7 to both sides

8y = 56

Divide both sides by 8

✍️y = 7
