Answer:  [tex]w^2+4w-36=0[/tex]

Step-by-step explanation:

Let w = width of the base of the shoebox.

As per given ,

Length = 8+2w centimeters

Area of base = 72 square centimeter

Area of rectangle =  Length x width

[tex]\Rightarrow\ 72=w(2w+8)\\\\\Rightarrow\ 72= 2w^2+8w\\\\\Rightarrow\ 2w^2+8w-72=0\\\\\Rightarrow\ w^2+4w-36=0[/tex]

Required equation: [tex]w^2+4w-36=0[/tex]

13y+12,6y−9=y

2 Switch sides.

y=13y+12,6y-9y=13y+12,6y−9

3 Break down the problem into these 2 equations.

y=13y+12y=13y+12

y=6y-9y=6y−9

4 Solve the 1st equation: y=13y+12y=13y+12.

y=-1y=−1

5 Solve the 2nd equation: y=6y-9y=6y−9.

y=\frac{9}{5}y=

Answer:

y = 1/4

Step-by-step explanation:

Yo no comprehendo espanol mucho, but I'll try

12y + 15 + y - 36y - 9 = y

Rearrange

12y + y (-y) + 15 (-15) - 36y - 9 (+9)= y (-y) (-15) (+9)

12y - 36y = - 15 + 9

-24y = - 6

Divide both sides by - 24 (Take note of the signs (+) (-))

-24y/-24 = - 6/-24

y= 1/4

Answer:

I'm getting

y=-7x+8

The 7 is negative for me..You should maybe try yourself too and see what you get I might have made a mistake

Step-by-step explanation:

I'm guessing you live somewhere in the U.S. so I'll use the equation you use there

Equation:

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

[tex]m = \frac{y1 - y2}{x1 - x2} [/tex]

first pick two points

I'll pick (0,8) and (1,1)

[tex]m = \frac{8 - 1}{0 - 1} = \frac{7}{ - 1 } = - 7[/tex]

this means that the slope is -7

So far the equation will look like this

[tex]y = - 7x + b[/tex]

to get b pick one point, I'll pick (0,8) and replace y and x

[tex]8 = - 7 \times 0 + b[/tex]

when you solve this you'll get b

[tex]b = 8[/tex]

So the equation will look this

[tex]y = - 7x + 8[/tex]

Answer:

17) 3   18) 3

Step-by-step explanation:

Answer:

17. C

18. C

Step-by-step explanation:

The greater the negative number, the less the number values. -10 is smaller than -8 because -10 is farther away from the number line to the left.

Go in terms of the tenths place. If its smaller than the number will be less than the bigger numbers. 0.227 is bigger than 0.18 because it has a 2 in the tenths place.

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Answer: 12 only

Step-by-step explanation:

The value of f(0) from the graph of f(x) is (a) 12 only

Functions are used to represent graphs, equations, ordered pairs and relations.

To interpret the value of the function, we start by reading the graph.

From the graph, the value of the function when x = 0 is 12

This means that:

[tex]f(0) = 12[/tex]

Hence, the value of f(0) from the graph of f(x) is (a) 12 only

Answer:

7 Units.

Step-by-step explanation:

First of all, you could just count the units, but that's not really too effective. Otherwise, you could start from the coordinates of the "C" point, and see how it's at -Y = -5. Therefore, to get to the line separating the two points, you would have to subtract 5 from 5 to get to the line. Now, you look at point "A". It's Y coordinate is 2. Therefore, adding 5 and 2 together gives you 7 units.

Answer:

The friends split the bill at 15.32$

Step-by-step explanation:

So to find how much each paid you would take the bill total and divide it by the amount of people in this case three

And for the equation it would be 45.96/3=15.32$

The equation to model the solution to the problem would be; 3x = 45.96. the friends split the bill at 15.32 dollars.

An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.

Given that the dinner for Lorenzo and his 3 friends costs $45.96.

To determine how much each paid would take the bill total

Therefore, we will divide it by the number of people in this case three

3x = 45.96

x = 45.96/3

x  = 15.32$

And for the equation would be; 3x = 45.96
