What The Answer And How You Got It -2x/7=3x-46 (2024)

Answer: y = (x-2)/3

This is equivalent to y = (1/3)x - 2/3

=================================================

To get this answer, we need to swap x and y in the original equation. Then solve for y to get the inverse.

y = 3x+2

x = 3y + 2 ... x and y swapped

x-2 = 3y

3y = x-2

y = (x-2)/3

y = x/3 - 2/3

y = (1/3)x - 2/3

This final equation has slope 1/3 and y intercept -2/3

Answer:

1X10^6

or

1.04x10^6

Step-by-step explanation:

You start by multiplying 5.2x10^4 by 20 because there are 20 petri dishes with this amount growing, and you get 1,040,000. Now we need to convert it to scientific notation. We know that 1,000,000 is 10^6, so we would move the decimal to the left 6 places and get 1.04x10^6. This is in scientific notation, but we need to keep in mind significant figures (sig figs), so your final answer would be 1x10^6, if that is not what your instructor is looking for, try 1.04x10^6.

Answer:

-1

Step-by-step explanation:

To visualize this on a number line you are moving four spots over to the left of 3 (since it is to the left, it is a negative four). 3 to 2 is the first movement to left, 2 to 1 is the 2nd movement, 1 to 0 is the third movement, and 0 to -1 is the fourth movement to the left.

Answer:

-1

Step-by-step explanation:

It's basically 3-4

Let's say you have to make 4 pies by 4:00 but only make 3. You'd be missing 1.

-8 3/4 + -11 1/3

I would do this problem by changing each mixed number into an improper fraction

-8 3/4 = -35/4
-11 1/3 = -34/3

Then I would find the common denominator

-35/4(3/3) = -105/12
-34/3(4/4) = -136/12

The interval notation given to us means that x is between negative infinity and 5, excluding both endpoints.

So we can write [tex]-\infty < x < 5[/tex] which shortens to [tex]x < 5[/tex]

The graph will have an open hole at 5 on the number line, and shading to the left to indicate all points smaller than 5.

Step-by-step explanation:

first you'll wanna take 23 divided by 2 which will be 11.5

next you multiply 11.5 by 13

Answer: 4/15

For fraction multiplication, multiply the numerators and then multiply the denominators

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 12 and 45 using

GCF(12,45) = 3

Therefore: it's 4/15

Answer:

x = 0

Step-by-step explanation:

x+\frac{6}{2}+5-4\cdot \frac{x}{3}-8-\frac{x}{6}=0

x+3+5-4\cdot \frac{x}{3}-8-\frac{x}{6}=0

x+3+5-\frac{4x}{3}-8-\frac{x}{6}=0

x-\frac{4x}{3}-\frac{x}{6}+3+5-8=0

x-\frac{4x}{3}-\frac{x}{6}=0

x\cdot \:6-\frac{4x}{3}\cdot \:6-\frac{x}{6}\cdot \:6=0\cdot \:6

6x-8x-x=0

-3x=0

\frac{-3x}{-3}=\frac{0}{-3}

Answer:

y = 2x - 3

Step-by-step explanation:

The graph is a straight line, thus linear with equation

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 3) and (x₂, y₂ ) = (6, 9) ← 2 points on the line

m = [tex]\frac{9-3}{6-3}[/tex] = [tex]\frac{6}{3}[/tex] = 2 , thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 3 ), then

3 = 6 + c ⇒ c = 3 - 6 = - 3

y = 2x - 3 ← equation relating x and y

The equation whigh relates x and y points on the graph can be expressed in slope-intercept form as y = 2x - 3

The general form of a slope - intercept equation is :

y = bx + cb = slope ; c = intercept

Slope, b = Rise / Run

Rise = 9 - 3 = 6 Run = 6 - 3 = 3

Slope, b = 6/3 = 2

Taking a pair of point on the graph :

(3, 3)

3 = 2(3) + c

3 = 6 + c

3 - 6 = c

c = - 3

Therefore equation can be expressed thus :

y = 2x - 3

I think 4/10 pizza he had ate .

The amount of the pizza he ate will be 9 / 40.

What is Algebra?

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

There are ten pieces of pizza.

Anthony ate 1/8 of the pizza for dinner.

Then the amount of pizza left will be

⇒ 1 – 1/8

⇒ (8 – 1) / 8

⇒ 7/8

He ate 3/10 for a bedtime snack.

Then the amount of the pizza will be

⇒ 7/8 – 1/10

⇒ 31/40

The pizza has he eaten in all.

Then the amount of the pizza he ate will be

⇒ 1 – 31/40

⇒ 9 / 40

Then the amount of the pizza he ate will be 9 / 40.

Answer:

(1/3)x+ x-20+ x-10+40= 360

Step-by-step explanation:

(1/3)x+ x-20+ x-10+40= 360

x+3x-60+3x-30+120=360*3

7x+30= 1080

7x= 1050

x= 150

The sum of the angles = 360.

Add the 4 angles together so they equal 360:

1/3x + x-20 + x-10 + 40 = 360

Combine like terms:

2 1/3x - 30 + 40 = 360

Continue combining like terms:

2 1/3x +10 = 360

Subtract 10 from both sides:

2 1/3x = 350

Divide both sides by 2 1/3:

x = 150

Answer:

2/14, 4/28, 5/35, 7/70 or just 2/14

Step-by-step explanation:

Multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14

And multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21. So 2:14 and 3:21 are two ratios that are equal to 1:7.

Answer:

z= 23°

y= 120°

Step-by-step explanation:

For z, the measures of the angles are alternate interior angles, they equal each other. So, the equation would be:

66= 3z-3

Step 1- Add 3 to both sides.

66= 3z-3

+3 +3

69= 3z

Step 2- Divide both sides by 3.

69= 3z

3 3

z= 23°

For y, the measures of 66 and y are alternate exterior angles, they sum up to 180 degrees. So, the equation would be:

180= 60+y

Step 1- Subtract 60 to both sides.

180= 60+y

-60 -60

y= 120°

Answer:

Step-by-step explanation:

On the first day, Ben (B) starts with 10 tubs and Winston (W) starts with 0 tubs.

After the first day, Ben sells 8 tubs per day while Winston sells 9 tubs per day.

Therefore we can write the following equation: (Where d = number of days)

B = 10 + 8d

W = 0 + 9d = 9d

We are told that eventually they will sell the same amount which means

B = W

This means we can say,

10 + 8d = 9d

If we subtract 8d from both sides we get

10 = d

Therefore it will take 10 days for them to sell the same amount of cookie dough.

Answer: 10 days

10 + 8 x 10 = 90

9 x 10 = 90.

It will take 10 days for Ben and Winston to sell the same amount of cookie dough.

The area of the floor required to cover using carpet is equal to 24 square yards .

To calculate the area of the room in square yards,

convert the dimensions from feet to yards and then find the product of the length and width.

1 yard (yd) = 3 feet (ft)

Room length in yards

= 18 feet / 3 feet/yd

= 6 yards

Room width in yards

= 12 feet / 3 feet/yd

= 4 yards

Now, find the area of the room in square yards:

Area = Length × Width

Area = 6 yards × 4 yards = 24 square yards

Therefore, 24 square yards of carpet area required to cover the floor of the room.

Answer:

The answer is

[tex] \huge \boxed{y = - \frac{1}{2} x - 8 }[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is (0,-8) and slope - 1/2

We have

[tex]y + 8 = - \frac{1}{2} (x - 0) \\ y + 8 = - \frac{1}{2} x \\ y = - \frac{1}{2}x - 8[/tex]

We have the final answer as

[tex]y = - \frac{1}{2} x - 8 \\ [/tex]
