Which linear function has a negative slope

Answer:

when x = 3 1/3, y = 4.5

or

when x =3 , y = 5

Step-by-step explanation:

Here, we want to solve using substitution

xy = 15

let x = 15/y

Put this into the first equation;

3(15/y) + 2y = 19

45/y + 2y = 19

Multiply through by y

45 + 2y^2 = 19y

2y^2 -19y + 45 = 0

2y^2 - 10y - 9y + 45 = 0

2y(y-5) -9(y-5) = 0

(2y-9)(y-5) = 0

2y-9 = 0

or y-5 = 0

2y = 9 or y = 5

y = 9/2 or y = 5

y = 4.5 or y = 5

Recall;

x = 15/y

x = 15/4.5 or x = 15/5

x = 3 1/3 or x = 3

Mrs. Rodrigues should use Standard deviation.

The correct option is b.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.

Given:

Mrs. Rodrigues wants to compare the spread of the test scores of her two biology classes.

From the given choices:

The measures of spread include:

Range, quartiles, interquartile range, variance and standard deviation.

Standard deviation is the appropriate choice.

Therefore, standard deviation is the correct phrase.

The name of the shape in the figure is a hexagon.

A polygon is often a plane figure in geometry that is enclosed by a closed chain made up of a finite number of straight-line segments that end in a loop. The spots where two of these segments meet are referred to as the polygon's vertices (plural: vertices) or corners. These segments are known as its edges or sides.

Given a shape,

the shape is a polygon,

to name a polygon first count the number of sides of the figure,

as we count there are 6 sides for the shape,

There are some specific names for the shapes according to their number of sides, like

Number of Sides Name          

3                      Triangle                    

4                 Quadrilateral

5                    Pentagon

6                     Hexagon

The name for the shape is Hexagon.

Hence the name of the figure is Hexagon.

Step-by-step explanation:

Answer:

The possible coins are:

P = penny = $0.01

N = nickel = $0.05

D = dime = $0.10

Q = quarter = $0.25

H = half dollar = $0.50

We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)

Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X

We know that Adam has half as much money as Ben, this can be written as:

(A + B + C) = 3*X/2

The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.

For example, if X = $0.10

then:

(A + B + C) = $0.10*(3/2) = $0.15

We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.

if x = $0.50 then:

(A + B + C) = (3/2)*$0.50 = $0.75

Here we could have:

A = $0.50

B = $0.25

then: A + B = $0.75

But we still have the coin C.

If we take X = $0.25 then:

(A + B + C) = (3/2)*$0.25 = $0.375

We could round the right part to $0.40

then the coins in the left part would be:

A = $0.25

B = $0.10

C = $0.05

A + B + C =  $0.25 + $0.10 +  $0.05 = $0.40

This is a strech, but is the only thing we can make with the given problem.

May I please have brainliest? :)

Note: Consider the dependent variable is T instead of I, and we need to find the value of T when x=5 and y=-7.

Given:

[tex]T=3x+4y[/tex]

To find:

The value of T when x=5 and y=-7.

Solution:

We have,

[tex]T=3x+4y[/tex]

Putting x=5 and y=-7, we get

[tex]T=3(5)+4(-7)[/tex]

[tex]T=15-28[/tex]

[tex]T=-13[/tex]

Therefore, the value of T is -13 when x=5 and y=-7.

Answer:

Look below!

Step-by-step explanation:

Angle A = 180-47 = 133

Angle B = 180-32-Angle A = 180-32-47 = 101

Angle D = 90-32 = 58

Angle C = 180-47-58 = 75

Hope I helped!

Answer:

A=133 ,B=15, C=75  D= 58

Step-by-step explanation:

Angle 32, d, and right angle add up to 180. So 180=32+90+x. Then x = 58 (D). The all 3 angles in the triangle add up too 180 so 180=47+58+x. x=75 (C). The 47 and a equal to 180 degrees. 180-47=133. The 133+32+x=180. x=15 (B).
