Answer:

by using distributive property

4( 1 + 9 x) = 4.1 + 4.(9 x)

Step-by-step explanation:

Step :- 1

Explanation :-

The distributive property of multiplication states that when a number is multiplied by the sum of two numbers , the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.

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

Given 4 + 36 x = 4(1+9 x)

by using distributive property

4 .( 1+36 x ) = 4.1 + 4.(9 x)

= 4.1+4.9(x)

12. (r - 5)3 + r2 ifr= -3 and s= -4

Natasha2012 [34]

Answer:

-503

Step-by-step explanation:

the statement tell us:

(r - 5)^3 + r^2

r= -3

so we have:

(-3 - 5)^3 + (-3)^2

(-8)^3 + 9

-512+9 = -503

Identify the slope and y-intercept of the line whose equation is given. write the y-intercept as an ordered pair. y = negative 2

PSYCHO15rus [73]

The line having the equation, y = -2x + 5, has a slope = -2, and y-intercept = (0, 5). Thus, option A is the best choice.

The slope of a line is the tangent of the angle that the line makes with the positive side of the x-axis.

The y-intercept of a line is the point at which the line intersects the y-axis.

The standard form of a line is y = mx + b, where m represents the slope of the line, and b represents its y-intercept.

In the question, we are asked to identify the slope and the y-intercept of the line whose equation is y = -2x + 5.

Comparing the given equation of the line, y = -2x + 5, with the standard equation of a line, y = mx + b, we can say that,

m = -2, and b = 5.

Representing b as an ordered pair, we get (0, 5), as b represents the y-intercept which is a point on the y-axis, where the x-coordinate is always equal to zero.

Thus, we get the slope = -2, and the y-intercept = (0, 5).

The option representing the answer is option A.

What is the slope of the line through (6,9) and (7,1)

suter [353]

Slope of (6, 9) & (7, 1)

To find the slope, we use the equation : m = y₂-y₁ / x₂-x₁

**Remember : m = slope**

Let's say that (6, 9) is our first set of points, and (7, 1) is our second.

If those are our first and second points, then we now know this :

x₁ = 6, x₂ = 7, y₁ = 9, y₂ = 1

Now that we know that, we can simply plug those points into our slope equation.

m = y₂ - y₁ / x₂ - x₁

m = (1 - 9) / (7 - 6 )

Simplify.

m = -8 / 1

Simplify.

m = -8

So, our slope is -8.

~Hope I helped!~
