How to solve your question

Solve for y:

-y = 3 y

Subtract 3 y from both sides:

-y - 3 y = 3 y - 3 y

-y - 3 y = -4 y:

-4 y = 3 y - 3 y

3 y - 3 y = 0:

-4 y = 0

Divide both sides of -4 y = 0 by -4:

(-4 y)/(-4) = 0/(-4)

(-4)/(-4) = 1:

y = 0/(-4)

0/(-4) = 0:

Answer: | y = 0

Answer:

The coordinates are (-1,4)

Step-by-step explanation:

To get the coordinates, we use the internal division formula

Mathematically, that will be;

(nx1 + mx2)/(m+n) , (ny1 + my2)/(m + n)

In this case;

m = 5

n = 3

(x1,y1) = (-6,9)

(x2,y2) = (2,1)

Substituting these values, we have that;

(3(-6) + 5(2)/(5+3) , (3)(9) + 5(1))/(5 + 3)

= (-18 + 10)/8 , (27+5)/8

= -8/8,32/8

= (-1,4)

Answer:

The equation of a line:

The graph of the line is attached below.

Step-by-step explanation:

Given the points

Finding the slope between (3,-4) and (3,-1)

(x₁, y₁) = (3,-4)

(x₂, y₂) = (3, -1)

Using the slope formula

m = y₂-y₁ / x₂-x₁

    = -1-(-4)) / 3 - 3

    = -1 + 4 / 0

m  = ∞

The slope of the line is undefined, then, by definition, the line would be a vertical line.

As the line that passes through the points (3,-4) and (3,-1)

Thus, the equation of a line:

The graph of the line is attached below.

Answer:

The correct options are;

1) How many grams of fat are in 1/2 cup of cheese = [tex]6 \div\dfrac{1}{4} \cdot \dfrac{1}{2}[/tex]

2) How many cups of cheese will the chef need to make 13 small pizzas = [tex]\dfrac{1}{2} \cdot 13[/tex]

3) How many small pizzas could the chef make if he has 3/4 cup of cheese is given as follows;

[tex]\dfrac{3}{4} \div \dfrac{1}{2}[/tex]

Step-by-step explanation:

1) How many grams of fat are in 1/2 cup of cheese

The number of grams of fat per 1/4 cup of cheese = 6 grams

Therefore;

The number of grams of fat per kilogram of cheese = 6/(1/4)

The number of grams of fat per 1/2 kilogram of cheese = 6/(1/4) × 1/2, which can be written as follows;

[tex]6 \div\dfrac{1}{4} \cdot \dfrac{1}{2}[/tex]

2) How many cups of cheese will the chef need to make 13 small pizzas

The number of cups of cheese per small pizza = 1/2 cup of cheese

Therefore, the number of cups of cheese in 1 small pizza = 1/2 × 13, which can be written as follows;

[tex]\dfrac{1}{2} \cdot 13[/tex]

3) How many small pizzas could the chef make if he has 3/4 cup of cheese is given as follows;

Given that 1/2 cup of cheese can make one small pizza

(1/2)/(1/2) = 1 cup of cheese can make 1/(1/2) small pizza

3/4 cup of cheese can make 3/4 × 1/(1/2)  = (3/4)/(1/2) small pizza, which can be written as follows;

[tex]\dfrac{3}{4} \div \dfrac{1}{2}[/tex]

Answer:

6 plants per row

Step-by-step explanation:

270 divided by 45 gives you 6, which is your individual value per row

Answer:

6 plants per row

Step-by-step explanation:

This is a fraction equal to

270 Plants ÷ 45 Rows

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 45

270 Plants ÷ 45

45 Rows ÷ 45

=

6 Plants

1 Row

=

6 Plants

Row

= 6 Plants per Row

Answer:

-8

Step-by-step explanation:

3/4x=-18+12

x=-6×4/3

x=-8

Answer:

x = -8

Step-by-step explanation:

[tex] \frac{3}{4} x - 12 = - 18[/tex]

i) multiply both sides of equation with 4

[tex] 4(\frac{3}{4} x - 12) = 4( - 18)[/tex]

[tex](4 \times \frac{3}{4} x) + (4 \times ( - 12)) = - 72[/tex]

[tex]3x - 48 = - 72[/tex]

ii) move -48 to the right-hand side and change its sign

[tex]3x = - 72 + 48[/tex]

iii) calculate the sum

[tex]3x = - 24[/tex]

iv) divide both sides of equation with 3

[tex] \frac{3x}{3} = \frac{ - 24}{3} [/tex]

[tex]x = - 8[/tex]

What is the answer u want dude

Step-by-step explanation:

Answer:

whats the answer

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

A function is any graph that the x values do not repeat.

You can check this by using this vertical line test

Run your finger or a pencil down a specific vertical (top to bottom) line on the graph, if you can see that it intersects into the graph more than once, then it's not a function.

Answer:

y = -2x - 3

Step-by-step explanation:

-solve for y: y = 1/2x + 2

-perpendicular equals opposite slope: -2

-plug in the point: (1) = -2(-2) + b

                               1 = 4 + b

                                b = -3

put it all together: y = -2x - 3

Answer:

  non-proportional y-value: 16.5

  corresponding proportional y-value: 18

Step-by-step explanation:

Each y-value is 4 times the corresponding x-value except for (x, y) = (4.5, 16.5).

The correct proportional values would be (4.5, 18).
