The solution of the equation 70 = 1.4y is 50.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 70 = 1.4y.

Seventy equal to one point four y.

In the given equation the variable is y.

We need to solve for the y.

70 = 1.4y.

Divide both sides by 1.4

70/1.4=y

Seventy divided by one point four equal to y

50=y

The value of y is fifty.

Hence, the solution of the equation 70 = 1.4y is 50.

∠7 = 180 - 90

∠7 = 90°

see image below

Answer:

90°

Step-by-step explanation:

angle 7 is supplementary to the angle next to itself which has a measurement of 90° and since the sum of two supplementary angle would be 180° we can say that m<7 = 90° as well

Answer:

-160

Step-by-step explanation:

All you have to do is substitute -2 for all values of x!

Is that last x raised to the power of 4 (looks like [tex]x^4[/tex])?

If so, the equation is:

[tex]f(-2)=2(-2-3)(-2)^4[/tex]

2(-5)(16)

-10(16)

Explanation:

f(3) means the value of f(x) when x = 3.

Locate 3 in the x column. The value just next to this is 9.

Therefore, f(3) = 9.

Answer:

y= -6x-4

Step-by-step explanation:

As two lines are parallel, their slope is same which is -6

Now, use:y-y1=m(x-x1)

y-(-4)= -6(x-0) (y1=-4,x1=0, cause the equation of y axis is x=0)

So,y= -6x-4

Answer: BBBBBB

Step-by-step explanation:

The correct option is,

"Yes because all the elements of set R are in set A"

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given the following sets;

U = {x | x is a real number}

A = {x | x is an odd integer}

R = {x | x = 3, 7, 11, 27}

Hence, The elements of the set A are,

⇒ A = {1, 3, 5, 7, 9, 11...}

R ⊂ A can be interpreted as R is a subset of A

i.e all the elements of R can be found in A.

Since, all the elements of R are all odd integers and can be fi=ound in A, hence R ⊂ A is TRUE.

The correct option is "Yes because all the elements of set R are in set A"

Answer:

Gopi made a loss in the deal

Step-by-step explanation:

To solve this question, we'll analyse each statement in the question one after the other.

From Roy to Mohan,

[tex]Selling\ Price = Ro.\ 60[/tex]

The profit of [tex]Ro.\ 10[/tex] goes to Roy

Mohan spent [tex]Ro. 27[/tex] on polish and repairs.

So, the cost price of the cupboard becomes

[tex]Cost\ Price = Ro.60 + Ro.27[/tex]

[tex]Cost\ Price = Ro.87[/tex]

He sells at a profit of [tex]Ro.8[/tex]. to Gopi

So, the selling price is:

[tex]Selling\ Price = Ro.8 + Ro.87[/tex]

[tex]Selling\ Price = Ro.95[/tex]

At this stage, the cost price of the cupboard to Gopi is:

[tex]Cost\ Price = Ro.95[/tex]

and

[tex]Selling\ Price = Ro.90[/tex]

Profit is calculated as:

[tex]Profit = Selling\ Price - Cost\ Price[/tex]

[tex]Profit = Ro.90 - Ro.95[/tex]

[tex]Profit =- Ro.5[/tex]

Because; the profit is negative, then it is a loss.

[tex]Loss = Ro.5[/tex]

Gopi made a loss in the deal
