Answers

Answer:

y=35z+20

Step-by-step explanation:

Y is the total cost, so it goes on the outside. 35z represents the months of service because you multiply 35 by however many months there are (for example, if you had 3 months, you'd have $35 3 times). Finally, the $20 is tacked onto the end because that's the initial payment to open an account

Mr. Nguyen bought a package of 4 chicken legs and a package of 6 chicken wings. Ms. Dawen bought a package of 3 chicken legs and a package of 6 chicken wings. Mr. Nguyen bought 52 ounces of chicken. Ms. Dawen bought 45 ounces of chicken. How much did each chicken leg and each chicken wing weigh?

Answers

Answer:

weight of legs - 7 ounces

weight of wings - 4 ounces

Step-by-step explanation:

Let the weight of a chicken leg be represented by l

Let the weight of a chicken wing be represented by w

The total weight of Mr. Nguyen's package can be represented by this equation :

4l + 6w = 52

The total weight of Ms. Dawen's package can be represented by this equation :

3l + 6w = 45

To find the weight of the legs and wing, use simultaneous equation

4l + 6w = 52 eqn 1

3l + 6w = 45 eqn 2

Subtract equation 2 from 1

l = 7 ounces

Substitute for l in equation 1

4(7) + 6w = 52

28 + 6w = 52

Solve for w

w = 4 ounces

What is an angle?

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

In the figure, the whole angle is 90°, the ray divide the angle into two angles such as 35° and 5x°.

From the given figure, we have

35°+5x°=90°

5x°=90°-35°

5x°=55°

x°=11°

Therefore, the value of x is 11°.

What is the recursive rule for the sequence −3, −1, 1, 3...?

Answers

Answer:

+2

Step-by-step explanation:

-3 + 2 = -1

-1 + 2 = 1

1 + 2 = 3

Answer:

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = - 1 - (- 3) = 1 - (- 1) = 3 - 1 = 2

A recursive rule allows a term in the sequence to be found by adding d to the previous term, that is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2

Find the slope of the line through the points (-3,1) and (-1,5).

Answers

Answer:

The slope is 2

Step-by-step explanation:

(-3,1)

+2 ——> (-1,5) <—— +4

m = y/x —> 4/2 —> 2

m = 2

Answer:

[tex]\boxed {\boxed {\sf m=2}}[/tex]

Step-by-step explanation:

The formula for slope is:

[tex]m= \frac {y_2-y_1}{x_2-x_1}[/tex]

where (x₁, y₁) and (x₂, y₂) are the points on the line.

We are given the points (-3,1) and (-1,5). Therefore,

[tex]x_1= -3 \\y_1= 1 \\x_2= -1 \\y_2=5[/tex]

Substitute the values into the formula.

[tex]m= \frac {5-1}{-1--3}[/tex]

Solve the numerator.

[tex]m= \frac{4}{-1--3}[/tex]

Solve the denominator.

-1 --3= -1+3 =2

[tex]m=\frac{4}{2} \\[/tex]

Divide.

[tex]m=2[/tex]

The slope of the line is 2.
