tl;dr: The slope is -5/2.

Hello!

First, if you get graphing paper and place those points, you'll see that the line is going down instead of up. This tells us that the slope is negative.

Now, we use the rise/run strategy.

Doing so, we are given 5/2. Since this is a negative, the slope will actually be -5/2.

So, the slope is -5/2.

Hope this was helpful. Please, correct me if I got something incorrect. Have a great day!

Answer:same number i think

Step-by-step explanation:

Since we are solving for b, you need to get it by itself. So you would divide both sides by 3a. That would leave b= -7/3a.

TRUE , the two system of equations are equivalent

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

We have two sets of equations

Let the first set of equation be A

Let the second set of equation be B

Equation set A :

6d + 4.5e = 16.5    be equation (1)

5d + 0.5e = 4   be equation (2)

Equation set B :

30d + 22.5e = 82.5   be equation (3)

5d + 0.5e = 4   be equation (4)

Now , we can see that Equation (3) is a multiple of Equation (1)

Multiply equation (1) by 5 , we get

5 ( 6d + 4.5e = 16.5 )

30d + 22.5e = 82.5   be equation (5)

Therefore , equation (5) = equation (3)

So , equation (1) = equation (3)

And , equation (2) = equation (4)

Therefore , Equation set A is equivalent to Equation set B

Hence , the two system of equations are equivalent

Answer:

18 yards

Step-by-step explanation:

To find the height of the kite we need to consider the problem as a right triangle and use the Pythagorean theorem to solve it:

[tex] c^{2} = a^{2} + b^{2} [/tex]

Where:

c: is the length of the hypotenuse

a and b: are the length of the sides of the triangle

We have that the length of one side is 29 yards and the length of the hypotenuse is 34 yards, so we need to find the other side (which represents the height) as follows:

[tex] a = \sqrt{c^{2} - b^{2}} = \sqrt{(34)^{2} - (29)^{2}} = 18 [/tex]                          

Therefore, the height of the kite is 18 yards.

Answer:

Step-by-step explanation:

There are 72,072 ways of choosing different councils consisting of 5 freshmen and 7 sophomores

A permutation is an arrangement of things where order matters, AB and BA are two different permutations.

The combination is a selection of things where order does not matter, AB and BA are the same combinations.

Given, A pool of possible candidates for a student council consisting of 14 freshmen and 9 sophomores.

∴ 5 freshmen out of 14 freshmen can be chosen in [tex]^{14}C_5[/tex] ways and 7 sophomores can be chosen out of 9 sophomores in [tex]^{9}C_7[/tex] ways.

So,  The no. of different councils consisting of 5 freshmen and 7 sophomores are possible is,

= [tex]^{14}C_5\times^{9}C_7[/tex] ways.

= 14!/(14 - 5)!×5! × 9!/(9 - 7)!×7! ways.

= 14×13×12×11×10/120 × 9×8/2 ways.

= 2002× 36 ways.

= 72,072.

Answer:

18

Step-by-step explanation:

w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:

w = kz

When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:

12 = 4k

Dividing both sides by 4:

12/4 = 4k/4

k = 3

Therefore the equation becomes:

w = 3z

The value of w when z = 6 is given as:

w = 3(6)

w = 18
