Answer:

x = $\frac{y-4}{7}$

Step-by-step explanation:

Given

y = 7x + 4 ( subtract 4 from both sides )

y - 4 = 7x ( divide both sides by 7 )

$\frac{y-4}{7}$ = x

Answer:

x = (y - 4)/7

Step-by-step explanation:

Subtract 4 from both sides to get:

y - 4 = 7x

Then, divide both sides by 7 to get:

(y - 4)/7 = x

Find the circumference of the circle. Use pi = 3.14

kotegsom [21]

Answer:

the answer is the option B

$18.84\ m$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

In this problem we have

$r=3\ m$

$\pi=3.14$

substitute the values

$C=2(3.14)(3)=18.84\ m$

What are all the possible rectangles with whole-number side

11111nata11111 [884]

Answer:

So (L,W) possibilities are:

(1,4),(4,1),(2,3),(3,2)

That makes 4 possibilities.

Step-by-step explanation:

The perimeter of a rectangle is P=2L+2W where L is the length and W is the width.

We have that P=10, so 10=2L+2W.

10=2L+2W

10=2(L+W) By factoring using the distributive property.

2(5)=2(L+W) I factored 10 as 2(5).

If 2(5)=2(L+W), then 5=L+W.

Whole numbers are {0,1,2,3,4,5,6,7,8,9,10,...}. They are your counting numbers and 0.

I think they want natural numbers {1,2,3,4,...}. This is also just called the counting numbers. The reason I think they want this because if one of the dimensions is 0, we won't actually have a rectangle.

So now looking for numbers from this set that satisfy: L+W=5.

L+W=5

1+4=5

4+1=5

2+3=5

3+2=5

So (L,W) possibilities are:

(1,4),(4,1),(2,3),(3,2)

That makes 4 possibilities.

What is the General form of this equation? (x- -1)^2 +(y-1)^2 =225.0

KATRIN_1 [288]

General Form is the most basic form of an equation and is used as a template to form equations designed to solve a specific problem.

The equation given is "(x- -1)^2 +(y-1)^2 =225.0".

The general form of this Equation would be presented as

·X (+/-) Y = Z
·X^2 (+/-) Y^2 = R1
