Answer:

x = 1 , y =− 2

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of  

x  opposite.

( − 4 ) ⋅ ( − 7 x − 8 y ) = ( − 4 ) ( 9 ) ( 7 ) ⋅ − 4 x + 9 y ) = ( 7 ) ( 22 )

Simplify.

y=-2

x=1

Use my head for most numbers. Sorry

Answer:

There are many to do this, but the simplest way is to put the fractions into a calculator (16*14)+9 ÷ 16 = 14.5625 . and (16*11)+13 ÷16 = 11.8125

If they are looking for which one is higher?  The birdhouse.  

If they want the difference? Subtract one from the other = 2.75 units

Answer:

Triangle 1 - 4

Triangle 2 - 10

Step-by-step explanation:

To find the missing side lengths of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem states that: a² + b² = c². In this equation, a and b are legs, and c is the hypotenuse.

Using this to solve triangle 1, you get the equation: a² + 3² = 5² or a² + 9 = 25. To solve for a², you subtract 9 from both sides to get a² = 16. To solve for a, find the square root of 16, which is 4.

Using the Pythagorean Theorem to solve for triangle 2, you get the equation: 6² + 8² = c² or 36 + 64 = c². Add 36 + 64 to get 100 = c². Find the square root of 100 to solve for c. The square root is 10.

Answer:

[tex]x^{2}[/tex]-25

Step-by-step explanation:

formula for areas of rectangles= width x height

width=x-5

height=x+5

(x-5)(x+5)= [tex]x^{2}[/tex]-5x+5x-25

since the 5x's cancel out each other

              =[tex]x^{2}[/tex]-25 will be the answer

The area of rectangle is [tex](x^{2} -25)[/tex] unit square.

The area of rectangle is product of length and width.

         [tex]Area = length*width[/tex]

Given that length is [tex](x+5)[/tex] and width is [tex](x-5)[/tex].

    [tex]Area=(x+5)*(x-5)\\\\Area=x^{2} -5x+5x-25=x^{2} -25[/tex]

Hence, the  area of rectangle is [tex](x^{2} -25)[/tex] unit square.

Answer:

5x-3

Step-by-step explanation:

This is linear because the numbers are changing at a constant rate (of 5)

We can also see that when x=0 y= -3 which means that in our equation

y=mx+b

-3 =b

I said prior that the rate of change is 5 which means that our slope is 5

which means that our equation looks like

Answer: 10 and a half For ivy For Hayden 8 half

Step-by-step explanation: because ivy gave Her mother 2 each and her father half and for her brother

Answer:

Given to father by Ivy: 12/2=6

Given to father by Hayden: 10/2=5

Now,

Chocolates given to mother by Ivy: 2

Chocolates given to mother by Hayden: 2

Now total chocolates given by Ivy to mother and father: 6+2 = 8

Now total chocolates given by Hayden to mother and father: 5+2=7

Now total chocolates left  with Ivy 12-8=4

Now total chocolates left with Hayden: 10-7= 3

Thus ivy and Hayden has  4&3 chocolates respectively

Answer:

only Katie is right

Step-by-step explanation:

first, find the nth rule using the equation n = a + (n - 1)d

a = first term (here, it's 22)

n = the position of a term

d = the constant difference between each term (here, it's -5 since each term reduces by 5)

put these in and then simplify:

n = a + (n - 1)d

n = 22 + (n - 1)(-5)

n = 22 - 5n + 5

n = -5n + 27

this can be rewritten as n = 27 - 5n, which means therefore that only Katie is right. hope this helps!

Answer: Only Katie

Reason: Only Katie is correct!
