Determine whether the two expressions are equivalent.

9 ( x + 3) ; 9x + 27

Answer:

g(-2) = -19, g(0) = -5 and g(3) = -14

Step-by-step explanation:

The given function is :

[tex]g(x) = -2x^2 + 3x - 5[/tex] ...(1)

We need to find the function when x = -2,0 and 3.

Put x = -2 in equation (1).

[tex]g(-2) = -2(-2)^2 + 3(-2) - 5\\\\=-19[/tex]

Put x = 0 in equation (1).

[tex]g(0) = -2(0)^2 + 3(0) - 5\\\\=-5[/tex]

Put x = 3 in equation (1).

[tex]g(3) = -2(3)^2 + 3(3) - 5\\\\=-14[/tex]

Hence, g(-2) = -19, g(0) = -5 and g(3) = -14

Step-by-step explanation:

A chef uses 2/3 cup of flour for every 1/8 cup of water in a dough recipe.

It means,

2/3 cup = 1/8 cup of water

[tex]1\ \text{cup}=\dfrac{\dfrac{1}{8}}{\dfrac{2}{3}}\\\\=0.1875[/tex]

Hence, the constant of proportionality is 0.1875.

Answer:

Step-by-step explanation:

1½ m = 1.5 m

¾ m = 0.75 m

area of rectangle = 1.5×0.75 = 1.125 m²

Each piece is half the rectangle. Area of one piece = 0.5625 m²

Answer:

The answer is [10+(9x3]+4 and 5x4+(7x3).

Step-by-step explanation:

I can't really explain, but if you add 10+4, it'll be 14.

If you multiply 9x3, it'll be 27.

So, if you add 27+14, it will be 41.

For the second answer:

If you also multiply 7x3, it'll be 21. If you ALSO multiply 5x4, its 20. So if you add 20+21, it will equal 41.

Answer:

f^-1(x) = (x + 4) / -5

Step-by-step explanation:

f(x) = -5x - 4        Substitute f(x) with y

y = -5x - 4         Switch the x and y variables

x = -5y - 4          Solve it down

x + 4 = -5y

y = (x + 4)/ -5

f^-1(x) = (x + 4) / -5          <----- This is the answer

Step-by-step explanation:

Answer:

a=21°b=70°c=89°

Step-by-step explanation:

a=21°[by vertical opposite angle]

b+110°=180°[by linear angle]

b=180°-110°=70°

a+b+c=180°[by sum of all angle]

21°+70°+c=180

91°+c=180°

c=180°- 91°

c=89°

To find the sizes of angles a, b, and c, we need to use the properties of straight lines and angles. Since angles on a straight line add up to 180 degrees, we have: Angle a = 21°, Angle b = 159°, Angle c = 159°

Angle b: We know that the sum of angles on a straight line is 180°. Angle b and angle a are on a straight line, so we can write the equation:

b + a = 180°

Given that angle a is 21°, we can now solve for angle b:

b + 21° = 180°

b = 180° - 21°

b = 159°

Angle c: Angles b and c are vertically opposite angles, which means they are equal in measure. So, we have:

c = 159°

Angle a: We already know the measure of angle a:

a = 21°

Answer:

h = 6 cm

Step-by-step explanation:

Given that,

The area of a trapezoid, A = 66 cm²

The sum of the lengths of the two bases of a trapezoid is 22 cm.

We need to find the height of the trapezoid.

The area of a trapezium is given by :

[tex]A=\dfrac{1}{2}\times (\text{sum of parallel sides})\times \text{height}[/tex]

Substitute the values,

[tex]h=\dfrac{2A}{\text{sum of parallel sides}}\\\\h=\dfrac{2\times 66}{22}\\\\h=6\ cm[/tex]

So, the height of the trapezoid 6 cm.

Answer:

Let x = BC

Answer:

268

Step-by-step explanation:

Answer:

The number that goes in the box is 268

Step-by-step explanation:

Equations

We are given an incomplete identity:

___ + 308 - 126 = 450

And it's required to fill the space with the number that makes the identity true.

Let's fill the space with a variable x:

x + 308 - 126 = 450

Solving for x implies doing inverse operations as shown on the left side.

We must add 126 and subtract 308:

x = 450 + 126 - 308

x = 268

The number that goes in the box is 268

Answer:

the jar will last for 15 days

Given:

The equation is [tex]xy=7[/tex].

To find:

Whether the given equation is a direct variation or inverse variable.

Solution:

Direct variation: y is directly proportional to x.

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

Inverse variation: y is inversely proportional to x.

[tex]y\propto \dfrac{1}{x}[/tex]

[tex]y=\dfrac{k}{x}[/tex]

Where, k is the constant of proportionality.

We have,

[tex]xy=7[/tex]

Divide both sides by x.

[tex]y=\dfrac{7}{x}[/tex]

It is in the form of inverse variation.

Since [tex]y=\dfrac{7}{x}[/tex] and it is inverse variation, therefore the correct option is (d).
