Can you help me fill in the table using this function rule?

OlgaM077 [116]

Answer:

5, 1 , -3 ,-7

Step-by-step explanation:

When x = -1

y = - 4 * (-1) + 1

= 4 + 1

= 5

When x = 0

y = - 4 * 0 + 1

= 0+ 1

= 1

When x = 1

y = - 4 *1 + 1

= - 4 + 1

= - 3

When x = 2

y = -4 * 2 + 1

= - 8 + 1

= - 7

Using the formula for the area of a triangle, , write an expression for the area of ΔABC. Base your answer on the work you did i

Montano1993 [528]

Answer:

$Area = \frac{1}{2} * AC * D$

Step-by-step explanation:

From the complete question, we have:

Length D to be perpendicular to side AC

So, the area of the triangle is:

$Area = \frac{1}{2} * Base * Height$

Since:

Length D is perpendicular to side AC

Then:

$Base = AC$

$Heigjt =D$

So:

$Area = \frac{1}{2} * AC * D$

If DC=6x and DA=4x+18, find the value of x then, find AD

shepuryov [24]

The value of x is 9 and AD is 54.

<u>Step-by-step explanation:</u>

From figure, if DC = AD, we can solve for value 'x'

DC = AD

Given:

DC = 6 x

DA = 4 x + 18

Equating the values of both, we get

6 x = 4 x + 18

6 x - 4 x = 18

2 x = 18

x = 9

So, the value of x is 9. By using this value of x, find AD

AD = 4 (9) + 18

AD = 36 + 18

AD = 54
