Step-by-step explanation:

3x+4=7x-4

add 7x to each side of equation 4x+3x+-7x=-4x+7x+-7x

combine like terms 7x+-7x=0

4+ -4x =-4 +0

4+-4x= -4

add -4 to each side of equation 4+ -4 +-4x=-4+-4

combine like terms -4 +4=0

0+ -4x = -4+ -4

combine like terms -4+-4=-8

-4x =-8

divide each side by-4

x=2

simplifying

x = 2

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

Answer:

For the first one its parallelogram

Step-by-step explanation:

We can write this word problem as two variables. Let us assume that:

x = Natalie's age

y = Fred's age

The first part of the word problem is that "If you add​ Natalie's age and​ Fred's age, the result is 39." Therefore:

Natalie's age + Fred's age = 39

x + y = 39

This will be our first equation. The second equation can be derived from the statement that "If you add​ Fred's age to 4 times​ Natalie's age, the result is 78." Therefore:

(4 times Natalie's age) + Fred's age = 78

4x + y = 78

We can now form a system of equations and solve for both x and y:

\(\left \{ {{x + y = 39} \atop {4x + y = 78}} \right.\)

The simplest way to solve would be using the Substitution method, as seen here:

x + y = 39

y = 39 - x

4x + y = 78

4x + (39 - x) = 78

3x + 39 = 78

3x = 39

x = 13

x + y = 39

13 + y = 39

y = 26

Remember that x = Natalie's age and y = Fred's age. Therefore, Natalie's age is 13 years old and Fred's age is 26 years old.

The ordered pair (-1, -7) is the solution to the equation 7x - 5y = 28.

The collection of variable values in linear equations that yields all feasible solutions is referred to as the solution of a linear equation. In order to describe real-world issues, linear equations contain unknown values in the form of one or more variables. The collection of values for each variable in a system of linear equations is referred to as the solution set.

Consider the equation,

7x - 5y = 28

Now put the values from options, the pair values at which LHS = RHS that will be the solution to the equation.

Put x = 77, y = 9 in the equation

7(7) -5(9)

= 49 - 45

= 4

This is not a solution.

Put x =4, y= 10

7(4) - 5(10)= 28 - 50

= -32

This is not a solution.

Put x= -1, y = -7

7(-1) - 5 (-7)

= -7 + 35

= 28

So, this is the solution to the equation as LHS = RHS

The fraction that compares BC to BD is 2/3.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

The distance between B and C is 2-0 = 2 units horizontally and 1-1 = 0 units vertically, so BC is a horizontal segment of length 2 units.

The distance between B and D is 3-0 = 3 units horizontally and 1-1 = 0 units vertically, so BD is also a horizontal segment of length 3 units.

Therefore, BC/BD = 2/3.

So the fraction that compares BC to BD is 2/3.

Answer:

C

Step-by-step explanation:

The red dotted line we see is the asymptote, which is a line that the functions will never cross.

The asymptotes we see currently is:

x = -3

and

x = 2

We can find the vertical asymptotes using the denominator of the function since the x value that makes the denominator 0 is the asymptote. Since -3 and 2 is the asymptote, the denominator of the function will be:

(x-2) (x+3)

If we look at the answer choices, we can see that C is the only option with a denominator of (x-2)(x+3), so that is our answer.

Answer:

C

Step-by-step explanation:

there are 2 vertical asymptotes at x = - 3 and x = 2

then the factors on the denominator will be (x + 3) and (x - 2)

then

f(x) = \(\frac{1}{(x-2)(x+3)}\)

A = 2184 cm²

Step-by-step explanation:

the area (A) of the figure is calculated as

A = \(\frac{1}{2}\) h(b₁ + b₂)

where h is the perpendicular height between the bases b₁ and b₂

here h = 42 , b₁ = 52 , b₂ = 52 , then

A = \(\frac{1}{2}\) × 42 × (52 + 52) = 21 × 104 = 2184 cm²

Answer:

A = 2184 cm2

Answer:

∠ QPT = 59°

Step-by-step explanation:

• the opposite sides are parallel

then

∠ SPT = ∠ QRT ( alternate angles ), that is

16x - 17 = 10x + 1 ( subtract 10x from both sides )

6x - 17 = 1 ( add 17 to both sides )

6x = 18 ( divide both sides by 6 )

x = 3

then

∠ SPT = 16x - 17 = 16(3) - 17 = 48 - 17 = 31°

• the vertices of a rectangle are right

∠ QPS = 90° , so

∠ QPT = 90° - ∠ SPT = 90° - 31° = 59°

This is because when you see the expression "at least," that implies that Addison wants to make $250 or anything above that, and nothing less than that. The expressions at least, at most, greater than and less than all denote an inequality.

At least 250 as sales means Addison wants to make 250 or anything greater than that.
