Step-by-step explanation:

please mark brainliest ☺♦

The equation represents a line which is parallel to the line 7y−x=−28 is y=1/7 x.

The given equation is 7y-x=-28.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Here, equation can be rewritten as x-7y-28=0

So, slope of line = 1

As we know, slope of parallel lines are equal. If the slopes of two parallel lines are represented as m1, m2 then we have m1 = m2.

Now, m1 = m2 = 1

Find the slope of the original line and use the point-slope formula y−y1=m(x−x1) to find the line parallel to 7y−x=−28.

y=1/7 x

Therefore, the equation represents a line which is parallel to the line 7y−x=−28 is y=1/7 x.

Answer:

14 pieces of candy

Step-by-step explanation:

Junior's candy tax is working great for him. When any other student buys candy from the student store,

We are told that Junior's tax =

Junior takes two pieces for himself for every five pieces the student buys.

If his friend George bought 35 pieces of candy, how many pieces will go to Junior?

The tax is represented as :

Junior : George

2 : 5

Hence:

2/5 = x/35

Cross Multiply

5x = 2 × 35

x = 70/5

x = 14

Hence, if George buys 35 pieces of candy, 14 pieces of candy goes to Junior

Answer:

The triangle ABE and DCE are congruent because they are the same size and same shape meaning they are congruent.

For two figures to be congruent they must be the same size and shape or one could mirror the other since they mirror each other and are the same size and shape they are congruent.

Answer:

a

Step-by-step explanation:

To draw a scaled copy of the polygon using a scale factor of 1/3, just multiply the given sides of the polygon with 1/3 and the outcome is the new polygon with a scale factor of 1/3.

You shall specify the extent of the shape's enlargement when describing one. The scaling factor refers to this. A scale factor of 2, for instance, indicates that the new shape is twice as large as the previous shape.

The size of the shape reduces when the scaling factor is a fraction, yet we still refer to this as an enlargement. A scale factor of 1/4 therefore indicates that the new shape is 1/4 as large as the old one.

Make sure you never confuse the scale factor. One might mistake a scale factor of 2 for a scale factor of 12, or a scale factor of 4 for a scale factor of 14.

Answer:

The equations are;

a -b + c = 5

c = -4

16a + 4b + c = 0

Step-by-step explanation:

Generally, the equation of a quadratic formula can be written as;

y = ax^2 + bc + c

From the graph, we have three points and we want to form equations from these points

These points are;

(-1,5) (0,-4) and (4,0)

To get the equation from each point, we make a substitution for both x and y

For the first;

5 = a(-1)^2 + b(-1) + c

5 = a-b + c

For the second;

-4 = a(0)^2 + b(0) + c

c = -4

For the third;

0 = a(4)^2 + b(4) + c

0 = 16a + 4b + c

The perimeter and area of the rectangle shown are 22 centimeters and 30 centimeters square respectively.

From the diagram shown, we have that the each point measures 1 centimeter

The length of the rectangle measures 5 pints which is 5 centimeters

The width of the rectangle measures 6 points which is 6 centimeters.

The formula for perimeter of a rectangle is expressed as;

Perimeter = 2 ( length + width)

substitute the values into the equation

Perimeter = 2 ( 5 + 6)

Perimeter = 2(11)

Perimeter = 22 centimeters

Area = length × width

Area = 6 × 5

Area = 30 centimeters square

Thus, the perimeter and area of the rectangle shown are 22 centimeters and 30 centimeters square respectively.

Answer:  (- 0.3636, - 0.2727)

Step-by-step explanation:

2x + y = - 1

3x - 4y = ​0

X= - 0.3636

Y=  - 0.2727

Therefore, for 1 bag of chips, he used 4 bags of Cheetos.

Given that 1/2 bag of chips is used for every 2 bags of Cheetos.

Now we have to determine how many bags of Cheetos did he use if he used 1 bag of chips as

1/2 bag of chips  = 2 bags of Cheetos

1 bag of chips = x

1/2 / 1 = 2 / x

By cross multiplying we get

1/2 x = 2

x = 2 / 1/2

x = 2 * 2

x = 4

Therefore, for 1 bag of chips, he used 4 bags of Cheetos.
