Help me solve for 16 and 17
Makovka662 [10]

Answers:

16. 6-x= 10

move +6 to the other side

sign changes from +6 to -6

6-6-x= 10-6

-x= 4

Mutiply both sides by -1

(-1)(-x)= (-1)(4)

x= -4

17. 4a+3= -9

move +3 to the other side

sign changes from +3 to -3

4a+3-3= -9-3

4a= -12

divide both sides by 4

4a/4= -12/4

a= -3

Write an equation in slope intercept form of a line passing through the given point (8,5) m=3
Zepler [3.9K]

If m(slope)=3, you can start to set up the equation as y=3x+b.

Using y=3x+8, you can plug in the given point being (8,5).

y=5

x=8

5=(3*8)+b

5=24+b

b=-19

The equation would be y=3x-19

Joey wants to build a rectangular garden. He plans to use a side of a river for one side of the garden, he will not place fencin
jonny [76]

We let x and y be the measures of the sides of the rectangular garden. The perimeter subtracted with the other side should be equal to 92.

<span>                                                       2x + y = 92</span>

The value of y in terms of x is equal to,

<span>                                            y = 92 – 2x</span>

The area is the product of the two sides,

<span>                                                                        A = xy</span>

Substituting,

<span>                                                            A = x (92 – 2x) = 92x – 2x2</span>

Solving for the derivative and equating to zero,

<span>                                                            0 = 92 – 4x  ; x = 23</span>

Therefore, the area of the garden is,

<span>                                                            A = 23(92 – 2(23)) = 1058 yard<span>2</span></span>
