Answers

Answer 1

Answer:

J (-4 , 1) -> J' (1 , 4)

K (-2 , 1) -> K' (1 , 2)

L (-2 , 5) -> L' (5 , 2)

Step-by-step explanation:

clockwise rotation 90°: (x,y) -> (y,-x)

J (-4 , 1) -> J' (1 , 4)

K (-2 , 1) -> K' (1 , 2)

A _____________ ratio in any proportional relationship.

Answers

Answer:

a proportional relationship is look at the different values that the variables take on when one variable is one value, and then what is the And then take the ratio between them. and you see y to x, or y divided by x-- the ratio of y to x

If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

We have to get ratio of the two quantities for all the given values. If all the ratios are equal, then the relationship is proportional. If all the ratios are not equal, then the relationship is not proportional.

Writing an Equation to Represent a Proportional Relationship. An expression of equality of ratios is called a proportion. The proportion expressing the equality of the ratios A:B and C:D is written A:B = C:D or A:B::C:D. A is to B as C is to D.

Step-by-step explanation:

Proportions are the same ratios written in different forms. A proportional relationship is states that they are the same. For example, 1/2 and 6/12 have a proportional relationship, which means they are the same.

A submarine starts at 0 units and has groups of 3 floats and groups of 4 anchors attached.
Using these groups of floats and anchors, write as many different expressions as you can that would make the submarine's final position -5 units.
write three expressions

Answers

Answer:

-12

Step-by-step explanation:

The three equivalent expressions of the final position are:

-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

From the question,

Each float takes a step of 5 unitsEach group takes a step of 2 units

So, the final position of the submarine is:

Final = -(5)(3) - (2)(4)

The minus "-" sign implies that the submarine moves downwards i.e. it sinks

The equivalent expressions of the final position are:

-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

1. If kwame eats 3 slices and the family eats 18 slices thats a total of 21 slices. Each pizza is cut into eighths so there has to be 8 slices to each pizza. There are 3 slices left over for a total of 24 when the eaten slices are added to the left over slices. 24 divided by 8 is 3 pizzas.

Anita incorrectly wrote the equation z = w – 18 to describe the pattern in the table.

D Anita only compared the values in the row for z.

The best description for Anita's error is z = 9w.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an expression.

We have,

From the table,

The pattern that describes the table.

Let the pattern be z = mw + c

Now,

(3, 27) and (5, 45)

m = (45 - 27) / (5 - 3) = 18/2 = 9

Now,

(3, 27) = (w, z)

27 = 9 x 3 + c

27 - 27 = c

c = 0

Now,

The pattern for the table.

z = 9w

Thus,

The patter for the table is z = 9w.

Answer: there are eight blocks hidden in the cup.

Step-by-step explanation:

seeing that we don’t know how many blox are in the cup The cup would be a variable in this situation.

x + 4 = 12 cubes

to find your answer you would’ve solve for X, a.k.a. the cup.

x + 4 = 12 cubes

first you would do the inverse operation of addition so instead of adding four  you subtract four from four, so that it cancels out.  Whatever you do to one side you have to do to the other side so you would have to subtract 4 from The previous 12 cubes.

X = 12 - 4

and your final answer would be 8 cubes

x = 8

there are eight blocks/cubes hidden in the cup

1. N= 16 because like the base are equal so you have to multiply the 8*2

2.N=16 because like the bases are identical but the 2*8 they multiply

Answer:

n = 10 and n = 16

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then

[tex]4^{8}[/tex] × 4² = [tex]4^{(8+2)}[/tex]

= [tex]4^{10}[/tex] , thus n = 10

---------------------------------------------

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then

[tex](3^2)^{8}[/tex]

= [tex]3^{2(8)}[/tex]

= [tex]3^{16}[/tex] , thus n = 16
