Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Substitute in y:                   -10x = -7x + 6Add 10x to both sides:      0 = 3x + 6Isolate x term:                    -6 = 3xIsolate x:                             -2 = xRewrite:                              x = -2

Step 3: Solve for y

Define equation:                    y = -10xSubstitute in x:                       y = -10(-2)Multiply:                                  y = 20

Answer:

x = -2

y = 20

Step-by-step explanation:

y = -7x + 6

y = -10x​

y = -10x

-7x + 6 = -10x

3x = -6

x = -2

y = -7x + 6

y = -7 ( -2 ) + 6

y = 14 + 6

y = 20

Drag and drop the answers into the boxes to correctly complete the statement.

A sequence of transformations that maps △DEF to △D′E′F′ is a _____ followed by a ________.

Answers

Answer:

Step-by-step explanation:

△D′E′F′ is reflection of △DEF across y = - 1.

The transformation of the △DEF to △D′E′F′ is as follows; The △D′E′F′ is a reflection of △DEF across y = - 1.

What is the transformation of a graph?

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

As per the given triangle △DEF with vertices D (1, 2) , E (2, 0) , and F (−1, 0) .

The plot of the above triangle has been plotted below,

As per the given triangle △D′E′F with vertices D′ (1, −4) , E′(2, −2) , and F′ (−1, −2) .

The plot of the above triangle has been plotted below,

It is clear that △DEF is reflected and how much is reflected can be known by making equal distance.

Since it equals apart from y = -1 thus it will be a reflection of y = -1.

Hence "The transformation of the △DEF to △D′E′F′ is as follows; The △D′E′F′ is a reflection of △DEF across y = - 1".

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 400 feet. Determine the​ flag's length and width if the length is 80 feet greater than the width.

Answers

Answer:

Length-140 ft

Width-60 ft

Step-by-step explanation:

I tried many different combinations

Answer: 120 ft

Step-by-step explanation:

So the equation we start off with is

2l+2w=400 in this situation

Since we know one length is 80,

2l would be 160.

So now we have 160+2w=400

Now we can use the perimeter to find the width now that we know the 2l.

400-160=2w

2w=240

240÷2

W=120
