What's the slope of (-11,9) and (-7,9)

Mathematics
1 answer:
Fynjy0 [20]3 years ago
7 0

Answer:

\boxed {m = 4}

Step-by-step explanation:

Use the <u>Slope Formula</u> to help you find the slope of the two given points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

First Point: (x_{1}, y_{1})

Second Point: (x_{2}, y_{2})

-Apply the two given point onto the formula:

First Point: (-11, 9)

Second Point: (-7, 9)

m = \frac{9 - 9}{-7 + 11}

-Solve for the slope:

m = \frac{9 - 9}{-7 + 11}

m = \frac{0}{4}

\boxed {m = 4}

Therefore, the slope is 4.

What 2 numbers equal to 8 when multiplied and 6 when added
expeople1 [14]
2 nuumbers multiply to 8 an addd to 6
factor 8 and add teh factor pairs
1,8
2,4


8+1=9
2+4=6


numbers are 2 and 4

if you were to solve it the
xy=8
x+y=6

y=6-x
x(6-x)=8
6x-x^2=0
0=x^2-6x+8
facotr
0=(x-2)(x-4)
set each to zero
x-2=0
x=2

x-4=0
x=4

x=2 or 4 and since they are interchangable, the numbes are 2 and 4

A solid shape is made by joining two cones. Each cone has the same radius. One cone has The other cone has slant height = 2x rad
pshichka [43]

The given area of the shape of 57.8·π cm², and length of the slant sides

being a factor of the radius, gives the length of the radius as <u>3.4 cm</u>.

<h3>How can the length of the radius be calculated?</h3>

Given;

Radius of the two cones are equal.

Slant height of one cone = 2 × Radius

Slant height of the other cone = 3 × Radius

Surface area of the shape = 57.8·π cm²

The curved surface area of a cone = π·r·l

Required:

The radius of the cone.

Solution;

Surface areas of the cones are therefore;

π·r × 2·r, and π·r × 3·r

The total surface area is therefore;

π·r × 2·r + π·r × 3·r = 57.8·π

5·r²·π = 57.8·π

Which gives;

r² = 57.8 ÷ 5 = 11.56

r = √(11.56) = 3.4

  • The radius of the cones, r =<u> 3.4 cm</u>
