Answer:

24

Step-by-step explanation:

To calculate the output substitute x = - 3 into f(x), that is

Answer:

<h2>A = 37 cm²</h2>

Step-by-step explanation:

Look at the picture.

We have two rectangles:

15cm × 2cm and 7cm × 1cm.

Calculate the areas:

A₁ = 15 · 2 = 30 cm²

A₂ = 7 · 1 = 7 cm²

The area of the figure:

A = A₁ + A₂ → A = 30 cm² + 7 cm² = 37 cm²

Randy rented a rectangular storage shed with the volume of 357 ft does it sheds height is 8 and 1/2 ft and the width of is 6 ft
ollegr [7]

Answer:

7 feets

Step-by-step explanation:

Volume of shed, V = 357 feet³

Height of shed, H= 8 1/2 fts

Width of shed, W = 6 ft

Using the relation :

Volume = Length * width * height

357 = L * 6 ft * 17/2 feets

357 feets³ = L * 51 feets²

L = 357 feets³ / 51 feets²

Length, L = 7 feets

Point A (-6, 2) and B (4, k) lie on a line that has a slope of 3/5 Determine the value of K
____ [38]

Answer:

k=8

Step-by-step explanation:

We can solve using the slope formula

m= (y2-y1)/(x2-x1)

3/5 = (k-2)/(4- -6)

3/5 = (k-2)/(4+6)

3/5 = (k-2)/10

Multiply each side by 10

10*3/5 = (k-2)/10 *10

6 = k-2

Add 2 to each side

6+2 = k-2+2

8 = k
