Kaitaia has one more than 5 times the number or wristbands that shelly has. Rea has three more than twice the number that shelly

saul85 [17]

Answer: The required expression is 3x+4.

Step-by-step explanation:

Since we have given that

Let the number of wristbands that Shelly has be 'x'

Let the number of wristbands that Kaitaia has be $5x+1$

Let the number of wristbands that Rea has be three more than twice the number that shelly has be

$'2x+3'$

According to question, the expression that shows the number of wristbands more Katia has than Rea is given by

$5x+1-(2x-3)\\\\=5x+1-2x+3\\\\=3x+4$

Hence, the required expression is 3x+4.

The larger of two numbers is eight more than twice the smaller. The sum of the numbers is 10 less than three times the larger. F

Alinara [238K]

Answer:

-2 and 4

Step-by-step explanation:

Let's set the larger number to x, and the smaller to y. With these, we can set up our equations.

x = 2y + 8

x + y = 3x - 10

Now, we put the value of x into the second equation.

2y + 8 + y = 3(2y + 8) - 10

Now we can solve for y

3y + 8 = 6y + 24 - 10

3y + 8 = 6y + 14

8 = 3y + 14

-6 = 3y

-2 = y

Now that we have the smaller number, we can put it into the first equation and solve for the larger.

x = 2*-2 + 8

x = -4 + 8

x = 4

So your two numbers are -2 and 4.

Which is the formula for slope of a line.

PilotLPTM [1.2K]

If the line passes through the points $A(x_1,y_1)$ and $B(x_2,y_2),$ then the slope of the line can be determined as

$m=\dfrac{y_2-y_1}{x_2-x_1}.$

Then the equation of the line is

$y=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)+y_1.$

Answer: correct choice is B
