Which expression is equivalent to –(3 + 4x)?

Answer:

The two numbers are 6 and 19

Step-by-step explanation:

Assume that the two numbers are x and y

We are given that:

The sum of the two numbers is 25

This means that:

x + y = 25 ..........................> equation 1

We are also given that:

One number is twice the other plus 7

This means that:

x = 2y + 7 ..........................> equation 2

Substitute with equation 2 in equation 1 and solve for y:

2y + 7 + y = 25

3y + 7 = 25

3y = 18

y = 6

Now, substitute with the value of y in equation 2 to get x as follows:

x = 2y + 7

x = 2(6) + 7

x = 12 + 7

x = 19

Based on the above, we can conclude that the two numbers are:

6 and 19

Hope this helps :)

x+y=25 => x=-y+25

x= 2y+7

x=-y+25

x=2y+7

subtract the first equation from the 2nd

0=3y-18

y=6

x=19

Answer:

[tex]x=6,50[/tex]

Step-by-step explanation:

The revenue from their ticket sales is a function of the ticket price, x , and can be modeled with [tex](x-6)(250-5x)[/tex]

To find the two ticket prices at which the band would make no money at all, solve the following equation:

[tex](x-6)(250-5x)=0\\x-6=0\,,\,250-5x=0\\x=6\,,\,5x=250\\\\x=6\,,\,x=\frac{250}{5}\\\\x=6,50[/tex]

The two ticket prices at which the band would make no money at all is 6, 50.

Since the revenue from their ticket sales is a function of the ticket price, x , and can be modeled with (x - 6)(250 - 5x).

So here it can be like

(x - 6) (250 - 5x) = 0

x - 6 = 0, 250 - 5x = 0

x = 6, 5x = 250

x = 5, x = 50

hence, The two ticket prices at which the band would make no money at all is 6, 50.

Step-by-step explanation:

You take the 64 teams, split it in half, and then the exponent is r

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation that represents the number of teams t that remained in the tournament after r rounds is t = 64 x [tex](1/2)^{r}[/tex]

Option A is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 3x + 3 = 4 is an equation.

We have,

Number of teams = 64

The number of teams eliminated after each round = Half the team.

The equation represents the number of teams t that remained in the tournament after r rounds.

t = 64 x [tex](1/2)^{r}[/tex] ____(1)

Put r = 1, we must get 32 teams.

t = 64 x 1/2 = 32

Put r = 2 we must get 16 teams.

t = 64 x (1/2)² = 64 x 1/4 = 16

We see that (1) is the correct equation to represent the number of teams t that remained in the tournament after r rounds.

Thus,

The equation that represents the number of teams t that remained in the tournament after r rounds is t = 64 x [tex](1/2)^{r}[/tex]

Option A is the correct answer.

Answer:

[tex]\displaystyle y=\frac{1}{4}x+\frac{1}{4}[/tex]

Step-by-step explanation:

We want to find the equation of the line that passes through the point (-1, 0) and have the slope 1/4.

We can use the point-slope form given by:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

We will substitute (-1, 0) for (x₁, y₁) and 1/4 for the slope m. Therefore:

[tex]\displaystyle y-(0)=\frac{1}{4}(x-(-1))[/tex]

Simplify:

[tex]\displaystyle y=\frac{1}{4}(x+1)[/tex]

Distribute. Thus, our equation is:

[tex]\displaystyle y=\frac{1}{4}x+\frac{1}{4}[/tex]

Step-by-step explanation:

1. Subtracting 21 from 115 which gives you 94, but that wouldn't be the answer because its asking for two numbers with a difference.

2. From you subtract 21 from 94 which is 73, next subract 73 from 115 which gives you 42.

Answer:

35 degrees

Step-by-step explanation:

for all positive angles less than 360°, if csc (2x+30°)= cos (3y-15°), the sum of x and y is?​

Let the given expression be equal to 1, hence;

csc (2x+30°)= cos (3y-15°) = 1

csc (2x+30°) = 1

1/sin(2x+30) = 1

1 = sin(2x+30)

sin(2x+30) = 1

2x+30 = arcsin(1)

2x+30 = 90

2x = 90-30

2x = 60

x = 60/2

x = 30 degrees

Get the value of y;

cos (3y-15°) = 1

3y - 15 = arccos (1)

3y - 15= 0

3y = 0+15

3y = 15

y = 15/3

y = 5

Sum of x and y;

x+y = 30 + 5

x+y = 35degrees

Hence the sum of x and y is 35 degrees
