Answer:

Step-by-step explanation:

A linear equation is not always in the form y = 4.5 − 0.5x,

It can also be like y = 0.2(7 − x)

Or like y + 0.2x = 4.5

Or like y + 0.2x − 4.5 = 0 and more.

Answer:

B. 1.05x because adding 5% to the cost of the shoes is the same as  multiplying the cost by 1.05.

Step-by-step explanation:

Cost of a pair of shoe = $x

Tax on shoes = 5% of x

                       = 0.05 x

The total cost of shoe = cost price + tax

                       = $x + 0.05x

                       = $1.05x

This means that she would pay 1.05 multiplied by the cost of the shoes.

Example, assume that the cost of the pairs of shoe is $20, then;

Total cost = 1.05 x 20

                = $21.00

Thus, it can be inferred that adding 5% to the cost of the shoes is the same as  multiplying the cost by 1.05.

Answer:

B. 1.05x because adding 5% to the cost of the shoes is the same as  multiplying the cost by 1.05.

Answer:

A:30

Step-by-step explanation:

because 3+2(the ratio) =5

75(the total number or both) divide by 5

so 1 ratio=15

15 x 2(the ratio of dogs)

=30

Answer:

no its not

Step-by-step explanation:

x-11 is only supposed to have one y.

if its a funtion then x should only have one line comming out of it. if its not a finction then x has two lines coming out of it.

Answer: no because the x axis dont equal or match up with the y axis and because theres not a certain amount of numbers for it to equal to or match to.

Step-by-step explanation:

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.            please give me brainliest

Answer:

  (b)  38.5

Step-by-step explanation:

The polygon is a trapezoid with bases 4 and 7 and height 7. Its area is given by the formula ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(4 +7)(7) = 77/2

  A = 38.5 . . . . square units

Answer:

5

Step-by-step explanation:

At b = 5, we have a solid circle, and the value of b is greater than 5. Then the correct option is B.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given as

b ≥ 5

Then at b = 5, we have a solid circle, and the value of b is greater than 5.

Then the correct option is B.

Answer:

The answer is below

Step-by-step explanation:

Let h represent the height of the tree in meters and t represent the number of years after planting.

Initially a tree of height 1.85 m was planted, i.e. at t = 0, h = 1.85. It can be represented in form of (h, t) as (1.85, 0).

After seven years the height of the tree was 5.30 m, it can be represented as (5.30, 7). Hence the equation can be gotten using:

[tex]t - t_1=\frac{t_2-t_1}{h_2-h_1} (h-h_1)\\\\t-0=\frac{7-0}{5.30-1.85}(h-1.85)\\\\t= 2.03(h-1.85)\\\\t=2.03h-3.75[/tex]

Answer:

It would be 1,0

Step-by-step explanation:

This is because if you compare all the answers to the shaded side there would be a fit for all of them except 1,0.

Point (2, -2) lies on the dashed line which is not the solution to the system of inequalities. Then the correct option is B.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The points that lie on the dashed line will not be the solution to the equations.

Answer:

The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.

Step-by-step explanation:

Given that:

An airplane travels 5040 kilometers in 6 hours against the wind

An airplane travels 6000 kilometers in 5 hours with the wind

Let,

x be the speed of plane in still air

y be the rate of wind

Combined speed against the wind = x - y

Combined speed with the wind = x+y

Speed = [tex]\frac{Distance}{Time}[/tex]

x-y= [tex]\frac{5040}{6} = 840[/tex]

x - y = 840    Eqn 1

x + y = [tex]\frac{6000}{5} = 1200[/tex]    Eqn 2

Adding Eqn 1 and 2

x+y+x-y=1200+840

2x=2040

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{2040}{x}\\x=1020[/tex]

Putting x=1020 in Eqn 2

1020+y=1200

y=1200-1020

y=180

Hence,

The rate of plane in still air is 1020 kilometers per hour and rate of wind is 180 kilometers per hour.
