Graph the equation to solve the system. y=2x+7 1/2y=x+7/2

Mathematics

Given equation is y=2x+7 and \frac{1}{2}y=x+\frac{7}{2}

Let's simplify the 2nd equation \frac{1}{2}y=x+\frac{7}{2} before we can start graph so that calculation will be easy

\frac{1}{2}y=x+\frac{7}{2}

multiply both sides by 2 to cancel out fractions

2*\frac{1}{2}y=2*x+2*\frac{7}{2}

y=2x+7

which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.

y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.

8 books cost \$19.60$19.60dollar sign, 19, point, 60.
snow_tiger [21]

Answer: C=[ (10) x (19.60)÷ (8)]

Step-by-step explanation:

Given , The cost of 8 books = $ 19.60

Then, By UNITARY method , the cost of one book = ( Cost of 8 books ) ÷ ( 8)

i.e. The cost of one book = ($19.60) ÷ ( 8) ...(i)

Now , cost of 10 books = (10) x (Cost of one book)

From (i) , we get

Cost of 10 books =$[ (10) x (19.60)÷ (8)]

Let C be the cost of 10 books ( in dollars) .

So , the equation would help determine the cost of 10 :

C=[ (10) x (19.60)÷ (8)]

Answer:

the answer is 11%

Step-by-step explanation:

this is because

4x+15=6x-5 solve for x
hram777 [196]

Answer:

x = 10

Step-by-step explanation:

Breaking down the equation

4x+15=6x-5\\4x+15-15=6x-5-15\\4x=6x-20\\4x-6x=6x-20-6x\\-2x=-20\\\frac{-2x}{-2}=\frac{-20}{-2}

Simplification

\frac{-2x}{-2}\\=\frac{2x}{2} (\frac{-x}{-y} = \frac{x}{y})\\\frac{2}{2} = 1 = x\\\\\frac{-20}{-2}\\=\frac{20}{2}\\\frac{20}{2}\\=10

What happens to the diagonal of a rectangle when the rectangle is reflected across a line of symmetry? What does this suggest ab
SIZIF [17.4K]

When you reflect a diagonal over a line of symmetry, the diagonal will land perfectly on the other diagonal (and vice versa). This suggests that one diagonal is a mirror copy of the other.

Another way to put it: The vertex points of the rectangle will swap when we reflect over a line of symmetry. A diagonal is simply the opposite vertex points joined together. So this is why the diagonals swap places (because the vertices line up perfectly when you apply the reflection).
