ok well the simplified equation would be -y+9 so the coefficient front the variable term would be -1 because there is an implied 1 in front of the variable but it is negative because of the negative sign.

Answer:

-1

Step-by-step explanation:

The only variable term in 6 − y + 3 is y, and the coeff. of y is -1 (first possible answer).

Answer: second option

Step-by-step explanation:

The equation of the line in slope-intercept form is:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

Rewrite the expression as:

[tex]3x+y=10[/tex]

Solve for "y":

[tex]y=-3x+10[/tex]

You can identify that:

[tex]m=-3\\b=10[/tex]

Therefore, the line intersects the y-axis at the point (0,10)

For the graphs of inequalities with [tex]\geq\ and\ \leq[/tex] the line must be solid.

The inequality given is [tex]3x+y\geq 10[/tex] and it can be written as [tex]y\geq -3x+10[/tex]

Then, the shaded region must be above the solid line. Therefore  it does not include the origin (Observe the graph attached).

18 ÷ 2.5 = 7.2.

But since cake can't be exactly that we can estimate to 7 since it is the closest so, the answer is 7 pieces of cake.

Answer:

-25

Step-by-step explanation:

if you are multiplying x by -2/5 you have to divide each side by it to get

x = 10 ÷ -2/5

and if you change it to (10/1)/(-2/5)

                                    =(10/1) • -5/2

and whene you multiply them you get -50/2

which is -25/1 or -25

There is no exercise. I cannot answer it without an exercise.

For this case we must find the value of the variable "x" of the following equation:

[tex]y = 10^{x}[/tex]

We rewrite the equation as:

[tex]10 ^ {x} = y[/tex]

We take the logarithmic base 10 from both sides of the equation to remove the variable from the exponent.

[tex]log (10 ^ {x}) = log (y)\\x (log (10)) = log (y)[/tex]

The logarithmic base 10 of 10 is 1.

[tex]x * 1 = log (y)\\x = log (y)[/tex]

“Jesse bought 10 more pencils than erasers”       means    P = 10 + E

 “A pencil costs $0.15”   means that     $0.15*P was spent on pencils

 “an eraser costs $.22”    means that    $0.22*E was spent on erasers

 “He paid a total of $4.46”    means that   $0.15*P + $0.22*E = $4.46

15*(10+E)   +   22*E    =   446

                       150 + 37E = 446

                          37E = 296

                              E = 8   Jesse bought 8 erasers

Jesse bought 8 erasers. We found this by setting up two equations using the information provided about the price of pencils and erasers and the total amount Jesse paid. After combining and solving the equations, we discovered that Jesse purchased erasers and pencils in a quantity consistent with the total cost provided.

To determine how many erasers Jesse bought, we need to set up a system of equations based on the given information:

We can express this as two equations:

Solving for e (number of erasers):

Answer:

B

Step-by-step explanation:

Use the equation for the area of a parallelogram.

[tex]A=bh[/tex]

Now solve for [tex]h[/tex].

[tex]h=\frac{A}{b}[/tex]

Plug in.

[tex]h=\frac{450}{15}[/tex]

450/15 = 30

15h/15 = h

h = 30

the solution to the word problem is B, 30 inches

Answer:

She decorated 4 faces.

Explanation:

A rectangular pyramid has 5 faces in total. There are 4 lateral faces and a base. If the baker only decorated the lateral faces, then she decorated 4 faces.

Rectangular Pyramid:

Answer:

perimeter of a children's playground, area of a house, volume of a glass of orange juice.

Step-by-step explanation:

Certainly! Here are some real-world examples for each of the geometric concepts:
**Perimeter**: The perimeter is the total distance around the edge of a two-dimensional shape. A real-world example of perimeter would be the total length of fencing required to enclose a backyard garden. If you wanted to put a fence around your garden and your garden is a rectangle, you would measure the lengths of all four sides and add them together to find out how much fencing you need.
Area: Area refers to the size of a surface. It is measured in square units (like square meters, square feet, etc.). A real-world example of area could be the amount of paint needed to cover a basketball court. If you wish to repaint the surface, you need to calculate the area of the court to determine how much paint to buy. The area is the product of the length and the width of the basketball court.
**Volume**: Volume measures the amount of space within a three-dimensional object; it is expressed in cubic units (like cubic meters, cubic inches, etc.). A real-world example of volume is the amount of water needed to fill a swimming pool. To determine how much water you need, you would calculate the volume of the pool by multiplying the pool's length, width, and depth. The result would tell you how much water is required to fill the pool to the brim.

Answer:

Step-by-step explanation:

Definition of absolute value:

|a| = a if a ≥ 0

|a| = -a if a < 0

Examples:

|2| = 2

|-2| = -(-2) = 2

|0.45| = 0.45

|-0.45| = -(-0.45) = 0.45

|1000| = 1000

|-1000| = 1000

Therefore

|12| = 12

The side length of one square would be X, then the side of the second square would be 2X ( twice as long as the first one.)

Area of a square is side x side

The area of the first square would be x times x which becomes x^2.

The area of the second square would be 2x x 2x , which becomes 4x^2.

Now the sum of the two equals 45.

Now you have x^2 + 4x^2 = 45

Simplify to get:

5x^2 = 45

Divide both sides by 5:

x^2 = 45/5

x^2 = 9

Take the square root of each side:

x = √9

x = 3 cm.

The first square has side length x = 3 cm.

The second square was 2x = 2 *3 = 6 cm.
