mash [69]3 years ago
7 0

Answer:

x=10

Step-by-step explanation:

first substitute y with the value (-5)

2x+5(-5)=-5 which is simplified to 2x+-25=-5

add 25 to -5 which gives you 2x=20

then divide 20 by 2 which makes x=10

The graph highlights two other points on the trend line. Use them to find another equation for the trend line shown for this sca
frutty [35]

Option A:

The equation for the trend line is y = 82x + 998.

Solution:

The points on the line are (2, 1162) and (11, 1900).

Here, x_1=2, y_1=1162, x_2 = 11, y_2=1900

Slope of the line:

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

$m=\frac{1900-1162}{11-2}

$m=\frac{738}{9}

m = 82

Point-slope formula:

y-y_{1}=m\left(x-x_{1}\right)

y-1162=82\left(x-2\right)

y-1162=82x-164

Add 1162 on both sides of the equation.

y=82x+998

The equation for the trend line is y = 82x + 998.

Hence Option A is the correct answer.

Find the surface area of a cone with radius 5 ft and height 21 ft substitute pi for 3.14​
Kryger [21]

Answer:

<u>417.4ft^2</u>

Step-by-step explanation:

Surface area of a cone = πr(r+√r²+h²)

r is the radius

h is the height

Substitute

Surface area of a cone = π(5)(5+√5²+21²)

Surface area of a cone = πr(5+√25+441)

Surface area of a cone = π(5)(5+21.59)

Surface area of a cone = 3.14*5*26.59

Surface area of a cone <u>= 417.4ft^2</u>

<u>Hence the surface area of the cone is 417.4ft^2</u>
