Number 1 Right

Number 2: Since it's an absolute value you'll have 2 solutions:
I x+2 I = 5 ===> x = -3
& - I x+2 I = 5  ==> ===> x =7

Number 3: I r-7 I < = 5, r < = 12 & -I r-7 I < = 5 , = -r+7 < = 5 or r> = 12

& so on & so forth. Never forget that an absolute value may have 2 answers, the first one you take the positive value of the equation & the 2nd one you take the negative value & you solve

vlabodo [156]

If the surface area of the stand to be 35 ft². The number of ropes purchase is 45.3125ft and  Percent of stand area is 83%.

<h3> Number of ropes  and Percent of stand area</h3>

Given:

Base area=3ft²

Height=3.2 feet

Surface area=35ft²

a. Number of ropes

Surface area=2×Base area×Base perimeter×Height

Base perimeter(BP):

35=2×3+BP×3.2

35=6+3.2BP

Collect like term

3.2BP=35-6

3.2BP=9

Divide both side by 3.2BP

BP=29/3.2

BP=9.0625ft

Number of ropes=5×9.0625ft

Nimber of ropes=45.3125ft

b. Percent of stand area:

Percent of stand area=(9.0625ft×3.2)÷35ft²

Percent of stand area=29ft²÷35ft²×100

Percent of stand area=82.857ft×100

Percent of stand area=83% (Approximately)

Therefore the number of ropes purchase is 45.3125ft and  Percent of stand area is 83%.

If f(x)=-5^x-4 and g(x)=-3x-2,find (f+g) (x)
ASHA 777 [7]

Answer: (f-g)(x) = - 5^x + 3x - 2

Step-by-step explanation:

if f(x) = -5^x - 4 and g(x)= - 3x - 2,find (f-g)(x)

(f-g)(x) = -5^x - 4 - (-3x - 2)

(f-g)(x) = -5^x - 4 + 3x + 2

(f-g)(x) = - 5^x + 3x - 2
