At Jeff's pizza restaurant, the cooks mix 2 kilograms of Parmesan cheese and 16 kilograms of mozzarella. Which restaurant uses a lower ratio of Parmesan to mozzarella?Brian's restaurant
Jeff's restaurant
neither; the ratios are equivalent

Answers

Jeff's Restaurant uses less because if you simplify both of the ratios you get 1/9 and 1/8

What do the graphs of multiplicative patterns have in common?

Answers

Multiplicative patterns are the patterns in which when a constant value (apart from zero) is multiplied by a given input value to know the output value.Hence the graphs of multiplicative pattern have in common that they are repetitive for the same value. The multiplicative pattern graph for the above equation is attached below.

What is multiplicative pattern graph?

Multiplicative patterns are the patterns in which when a constant value (apart from zero) is multiplied by a given input value to know the output value. Such patterns are multiplicative pattern as they are repeating the values for variables with the same number.

Let a function of variable x for a line as,

y=4x

The value for variable y will be different for the different values of the variablex. For the given function when the value of x is 0 then

y=4*0

y=0

When the value of x is 1 then

y=4*1

y=4

When the value of x is 2 then

y=4*2

y=8

when the value of x is 3 then

y=4*3

y=12

Thus the values for the function is in the form of multiple of four. Such patterns are multiplicative pattern as they are repeating the values for variables with the same number.

Hence, the graphs of multiplicative pattern have in common that they are repetitive for the same value. The multiplicative pattern graph for the above equation is attached below.

Answer:

-125/27

Step-by-step explanation:

(-3/5)^-3= 1÷(-3/5)³

=1÷(-3³/5³)

=1÷(-27/125)

=1×(125/-27)

=-125/27

Answer:

-  (125)/(27)

make

( { ( - 3)/(5) })^( - 3)

the exponent postive by flipping the fraction around

( { (5)/( - 3) })^(3)

then simpify and you get

- 4 (17)/(27)

or for a single fraction

-  (125)/(27)

Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function Y=2x^2+12x+13
axis of symmetry:
vertex:

Answers

Answer:

Axis of symmetry: –3

Vertex: (–3, –5)

Step-by-step explanation:

For a quadratic function in standard form, the axis of symmetry is a vertical line x=-(b)/(2a). Therefore:

x=-(b)/(2a)=-(12)/(2(2))=-(12)/(4)=-3

For the vertex, –3 is the x-coordinate and we solve for y to find the y-coordinate:

y = 2x² + 12x + 13

y = 2(–3)² + 12(–3) + 13

y = 2(9) + 12(–3) + 13

y = 18 – 36 + 13

y = –5

Therefore, the vertex is (–3, –5).
