1/2(7x-8)+2x =2-(10x+4

1 answer:

8 0

<span>1/2(7x-8)+2x =2-(10x+4)
Distribute
(7x-8)/2 + 2x = 2 -10x -4
combine like terms
(7x - 8)/2 + 2x = -10x - 2
Multiply both sides by 2
7x - 8 + 4x = -20x -4
Combine like terms
11x - 8 = -20x - 4
add 8 to both sides
11x = -20x + 4
add 20x to both sides
11x + 20x = 4
combine like terms
31x = 4
divide both sides by 31
x = 4/31 or </span><span>0.129.

Hope this helps :)</span>

Which of the following equations is the formula of f(x) = x^1/3 but shifted 4 units to the left and 4 units up?

nlexa [21]

Answer:

Hence correct chcie is C.

$f\left(x\right)=(x+4)^{\frac{1}{3}}+4$

Step-by-step explanation:

Given function is $f\left(x\right)=x^{\frac{1}{3}}$

Now it says that function is shifted 4 units to the left and 4 units up.

We need to find about which of the given choice is correct for the given transformation.

When f(x) is shifted "h" units left then we write f(x+h)

So $f\left(x\right)=x^{\frac{1}{3}}$ will change to

$f\left(x\right)=(x+4)^{\frac{1}{3}}$

When f(x) is shifted "h" units up then we write f(x)+h

So $f\left(x\right)=(x+4)^{\frac{1}{3}}$ will change to

$f\left(x\right)=(x+4)^{\frac{1}{3}}+4$

These 3 questions pleaseeee!

Sergio039 [100]

Answer:

1. m<T =72 , m<U =54

2. EF= 18 in. , m<F=134'

3. x=4

Step-by-step explanation:

1. <s=<u , there is 180' in a triangle total so 180- <S - <U = <T

180 - 54 - 54 = 72

2. ef = gf

180 - 23 - 23 = 134

3. since bottom 2 angles are = , the 2 sides are also =

A 12,000-lb killer whale might eat as much as 14,000 lb of fish per month (assume a 30-day month). If the average weight of a ce

brilliants [131]

Answer:

2196 fish

Step-by-step explanation:

Weight of fish that the killer whale might eat in a month (30 days) = 14,000 lb

Weight of the fish that killer whale might eat in a day = $\frac{14000}{30} = \frac{1400}{3}$ lb.

Average weight of the fish that killer whale eats = 3.4 oz

Since,

1 pound(lb) = 16 ounces(oz)

So,

Weight of the fish that killer whale might eat in a day in ounces(oz) = $\frac{1400}{3} \times 16=\frac{22400}{3}$ oz

Since, a certain fish weighs 3.4 oz, in order to find the number of fish that killer whale must eat, we must divide the total weight in ounces by 3.4 ounces.

So, the number of fish that killer whale would eat = $\frac{22400}{3} \div 3.4 = 2196$ fish

Thus, the killer whale needs to eat 2196 fish.

C=2m+d solve for m plz

Pavel [41]

Isolate the m, go backwards for PEMDAS.

C = 2m + d
C (-d) = 2m + d (-d)
C - d = 2m
(C - d)/2 = 2m/2
m = (C - d)/2

m = (C - d)/2 is your answer

hope this helps
