Answer:

The slope for line a is 3/4 and for line b is 5/6.

Step-by-step explanation:

Slope formula: y2-y1/x2-x1

A: (-3,1) and (-7,-2)

x1=-3   y1=1   x2=-7     y2=-2

-2-1/-7-(-3)=-3/-7+3=-3/-4=3/4

B: (2,-1) and (8,4)

x1=2  y1=-1  x2=8   y2=4

4-(-1)/8-2=4+1/6=5/6

Hope this helps you:)

Given the expression 12 over 12 to the third power.
4vir4ik [10]
<u><em>Part 1:</em></u>
<u>Before we begin, you need to remember the following rule:</u>
\frac{x^a}{x^b} = x^{a-b}

<u>The given expression is:</u>
\frac{12}{12^3}

Since the base is the same in both numerator and denominator, we can apply the above rule. <u>This means that:</u>
\frac{12}{12^3} = 12¹⁻³ = 12⁻²

<u><em>Part 2:</em></u>
<u>Before we begin, you need to remember the following rule:</u>
x⁻ᵃ = \frac{1}{x^a}

Now, <u>from part 1</u>, we simplified the expression into 12⁻²
Since the power is negative, we can apply the above rule.
<u>This means that:</u>
12⁻² = \frac{1}{(12)^2} =  \frac{1}{12*12} = \frac{1}{144}

Hope this helps :)

My brain small so could you plz anwser his 6/11+ 2/ 3
Lena [83]

Answer:

1 7/33

Step-by-step explanation:

6/11 + 2/3 --> We need a common denominator

--> 11 x 3 = 33

33 is our common denominator

6 x 3 = 18

2 x 11 = 22

18/33 + 22/33 = 40/33

Convert to a mixed number

=> 1 7/33

Thus, we have our answer.

How can subtracting the equations help you solve the system?
devlian [24]

System of equations subtraction method

In the addition/subtraction method, the two equations in the system are added or subtracted to create a new equation with only one variable. ... Substitute the variable back into one of the equations and solve for the other variable. Check the solution--it should satisfy both equations.

Answer:

15.13cm

Step-by-step explanation:

From that above question:

We are told that:

Lateral surface area of a right circular cone : πr√r² + h²

We are give the following parameters:

Lateral surface area = 236.64cm²

Radius = 4.75cm

We are to find the height

Making h the subject of the formula

h = √[(A/r)² - πr²]/π

h = √[(236.64/4.75)²- π ×4.75²]/π

h = 15.12975 cm

Approximately to the nearest hundredth = 15.13cm
