-1/2 (10x-4) -( 4x-2)

From these problems, we have that:

Hence the algebraic expression is: 10 + 9y.

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the expression is:

(10 - 3y) - 1.

When y = 3:

(10 - 3 x 3) - 1 = 1 - 1 = 0.

The quotient between two amounts a and b is given by a divided by b. For example, the quotient between 10 and 2 is:

10/2 = 5.

Answer:

Breadth of stamp=3 cm

Length of stamp=4 cm

Area of stamp = Area of rectangle = l*b = 3*4 = 12 cm^2

Side of square card = 12 cm

Area of card = Area of square = side^2 = 12^2 = 144 cm^2

No. of stamps that can be filled in card

= Area of card / Area of stamp

= 144/12

= 12

:. 12 stamps can be filled in a card of side 12 cm.

Answer: The answer will be in the explanation

Step-by-step explanation:

In step 2 she made the mistake of not dividing the 12/2 and replacing 5 with -13. In step 4 she made the mistake of removing the coefficient. The correct way to do it is this way. Look below on how to do it correctly!

(\sqrt[3]{125}-12/2)(4-6)^2

Step-by-step explanation:

Let f(y)=x.

[tex]x=-\frac{1}{2}\sqrt{y+3} \\ \\ -2x=\sqrt{y+3} \\ \\ 4x^2=y+3 \\ \\ y=f^{-1}(x)=\boxed{4}x^2-\boxed{3}[/tex]

The domain of the inverse is the same as the range of the original function. For the original function, we know that it is decreasing, so the range is

[tex]y\leq -\frac{1}{2}\sqrt{-3+3}=0[/tex]

and hence the domain of our inverse is

[tex]x \leq 0[/tex]

Answer:

[tex]y=-(x+6)^2[/tex]

Step-by-step explanation:

Shifting 6 units left, we get:

Reflecting over the y-axis. we get:

[tex](x+6)^2 \longrightarrow -(x+6)^2[/tex]

So, the final equation is

The required length of the hose is 20 feet.

Given,

a = 16 feet

b = 12 feet

c = ?  (the required length of hose)

we can use the formula

c = √(a²+b²)

⇒  c = √(16²+12²) feet

        = 20 feet.

The area can be defined as the amount of space covered by a flat surface of a particular shape. It is measured in terms of the "number of" square units (square centimeters, square inches, square feet, etc.) The area of a rectangle is the number of unit squares that can fit into a rectangle. Some examples of rectangular shapes are the flat surfaces of laptop monitors, blackboards, painting canvas, etc. You can use the formula of the area of a rectangle to find the space occupied by these objects. For example, let us consider a rectangle of length 4 inches and width 3 inches.

The area occupied by a rectangle within its boundary is called the area of the rectangle.

Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

In geometry, a line segment is defined as two different points on a line. In contrast, a line segment is a piece of a line that connects two points. A line has no endpoints and runs indefinitely in both directions, whereas a line segment has two fixed as well as definite endpoints.

Yes. A ray is not the same as a line segment. A ray has one endpoint, but a line segment has two. The ray's one end extends indefinitely, whereas the endpoints of a line segment are always specified and fixed.

When E = 4 on the number line, then F can either be 11 or be 19 to make EF as 15 units.

We are given that:

E and f are the points on a number line.

We are also given that the distance between E and F is:

EF = 15 units

Now, we know that E lies at 4

E = 4

We need to find the location of the point F

Now, since we also know that:

EF = F ± E

Substituting the values:

15 = F ± 4

We get that:

15 = F + 4   or   15 = F - 4

F = 15 - 4    or   F = 15 + 4

F = 11           or   F = 19

Therefore, we get that, when E = 4 on the number line, then F can either be 11 or be 19 to make EF as 15 units.

Answer:

h = -13

Step-by-step explanation:

Use PEMDAS to solve this problem.

11h - 5(h + 3) = -63

~Use distributive property to simplify [ a(b + c) = ab + ac ]

11h - 5h + 15 = -63

~Combine like terms

6h + 15 = -63

~Subtract 15 to both sides

6h = -78

~Divide 6 to both sides

h = -13

Best of Luck!

Answer:

Step-by-step explanation:

11h - 5(h + 3) = -63

-Multiply parenthesis so

-5(h) + -5(3) = -5h - 15

New equation: 11h - 5h - 15= -63

                                   +15  +15

(add 15 to both sides)

The percent of the computer programmer’s salary deducted for income tax is 17%.

What is percentage of a number?

A percentage is a ratio or number that can be expressed as a fraction of 100. In order to calculate a percentage of a number, we must divide it by 100 and then multiply the resulting number by 100. The proportion therefore denotes a component per 100. A percentage of one hundred is what is meant by the word "percent."

Given, weekly wage is $1350 and deduction amount for income tax is $229.50.

The percent of deduction is

[tex]\frac{229.50}{1350} \times 100\\=0.17 \times 100\\=17[/tex]
