if y varies directly with x and x increases by 2 , is it possible to determine by how much y increases or decreases . yes or no and why

Answers

Answer 1
Yes

Since it varies directly, you would have to find what percentage of x the value 2 is and increase y by the same percent
Answer 2

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

y ∝ x

y = kx

Where k is a constant and it can be any integer.

If y varies directly with x.

Yes, it is possible to determine by how much y increases or decreases as x increases.

If x increases by 2 then y also increases by 2.

What is an equation?

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

We have,

y varies directly with x.

This can be written as an equation,

y ∝ x

y = kx

Where k is a constant and it can be any integer.

Now,

If x increases by 2.

y = 2k

If k = positive integer

Then y will increase by 2k.

If k = negative integer

Then y will decrease by -2k

So,

Yes, it is possible to determine by how much y increases or decreases.

Thus,

If y varies directly with x.

Yes, it is possible to determine by how much y increases or decreases as x increases.

the addition property of equality and then the multiplication property of equality
the subtraction property of equality and then the division property of equality
the subtraction property of equality and then the multiplication property of equality

Answers

Answer:

The right answer is:

the addition property of equality and then the division property of equality

Step-by-step explanation:

Given equation and steps to solve it are:

Step 1: –3x – 5 = 13

Step 2: –3x = 18

Step 3: x = –6

In step two, -5 has to be removed from left hand side of the equation so additional property of equality will be used i.e. adding 5 on both sides

Similarly in the third step, to remove -3 with x , division property of equality will be used i.e. dividing both sides by -3

Hence,

The right answer is:

the addition property of equality and then the division property of equality

Answer:

A) the addition property of equality and then the division property of equality

How many soap cakes can be placed in a box of size 56 cm x 0.4 m 0.26 m, if the size
of a soap cake is 7 cm x 5 cm x 2.5 cm?​

Answers

Answer:

length of box = 56cm

breadth = 0.4m = 40cm

height = o.25m = 25cm

Volume of Box = Volume of soap × n

n = number of soaps.

LBH = lbh × n

56 × 40 × 25 = 7 × 5 × 2.5 × n

n = 56×40×25/35×2.5

n = 56000/87.5

n = 640

so, 640 soaps can be placed in the box.

So the base points of that triangle are both 47, to find the angle of BYC, you just do:

180 - 47 - 47 = 86

and then since x is on a line with 86, and angles on a straight line add up to 180:

180 - 86 = 94

solve as multi-step eqaution 24(34 + r) = 1200

Answers

The value of 'r' in the expression 24(34 + r) = 1200 is 16.

What are the basic properties of arithmetic laws of operations?

There are three types of basic arithmetic laws of operation.

Commutative law for addition and multiplication states,

a + b = b + a.

a×b = b×a.

Distributive law states,

a(b ± c) = ab ± ac.

Associative law states,

a + (b + c) = (a + b) + c.

Given, An expression 24(34 + r) = 1200.

First, we'll distribute LHS,

24×34 + 24×r = 1200.

816 + 24r = 1200.

24r = 1200 - 816.

24r = 384.

r = 384/24.

r = 16.
