Answer:
x = -2
Step-by-step explanation:
y = -4
2x -3y = 8
Substitute the first equation into the second equation
2x - 3(-4) = 8
2x +12 = 8
Subtract 12 from each side
2x+12-12 = 8-12
2x = -4
Divide by 2
2x/2 = -4/2
x = -2

Add f(x)=2x^3 and g(x) = log(x+4) + 100
The sum of the given function is 2x^3 + log(x+4) + 100
Sum of functionsGiven the following functions
f(x)=2x^3 and;
g(x) = log(x+4) + 100
Take the sum of the functions
f(x) + g(x) = 2x^3 + log(x+4) + 100
Hence the sum of the given function is 2x^3 + log(x+4) + 100

2. George went to the store for a sale on designer socks. Each pair was $3 off. She bought 6 pairs for $31.20. How much was the original price of the socks?
Answer:
a. 8 years
b. $49.20
Step-by-step explanation:
The computation is shown below:
a. The mark age is
Given that
232 is 8 times of the sum of mark and his sister ages
And, his sister is 21
So,
Let us assume the mark age be x
now
8(x + 21) = 232
x + 21 = 29
x = 29 -21
x = 8
b. The original price of the socks is
As each pair get $3 off
And she bought 6 pairs for $31.20
= $31.20 + 6 × $3
= $31.20 + 18
= $49.20

A bag contains 9 and 54 blue marbles. If a representative sample contains 3 white marbles, then how many blue marbled would you expect to contain? Explain
Answer:
There should be 18 blue marbles in the representative sample.
Step-by-step explanation:
Given that a bag contains 9 white and 54 blue marbles, if a representative sample contains 3 white marbles, to determine how many blue marbles would you expect to contain the following calculation must be performed:
9 = 3
54 = X
54 x 3/9 = X
162/9 = X
18 = X
Therefore, there should be 18 blue marbles in the representative sample.

Just find the figure of the rectangle plss
Answer:
x= 21
y= 3
z= 21
Step-by-step explanation:
Let the center be O,
=> Triangle AOD is an Isosceles triangle so AO≅DO, "21 = x"
=> Line AC is divided in two equal parts by the center so if AO= 21 then
7y = 21, and thus "y = 3"
=> BOC is also an Isosceles triangle so CO ≅ BO, if CO = 21 (7y → 7*3) then so will be BO. Therefore "z = 21"

Answer:
volume of hemisphere = 452.16 ft³
volume of cylinder = 2260.8 ft³
total volume = 2712.96 ft³
1/3 full = 904.32 ft³
Step-by-step explanation:
volume of hemisphere = 1/2(4/3)(3.14)(6³) = 452.16 ft³
volume of cylinder = (3.14)(6²)(20) = 2260.8 ft³
total volume = 452.16 + 2260.8 = 2712.96 ft³
1/3 full = 2712.96/3 = 904.32 ft³

what is the equation of a line perpendicular to y=-1/3x+1 and passes through the point (1,-1)
Answer:
y = 3x - 4
Step-by-step explanation
If the line is perpendicular, then it means that the slope will be opposite. So if it's -1/3 then it will become 3.
y = 3x + b
-1 = 3(1) + b
-1 = 3 + b
-4 = b
The equation is y = 3x - 4

The range of the function f(x) = -4|x + 1| − 5 is (-∞, -5). The correct option is A.
What are a domain and range?The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f. (x). A function's range is the set of values that the function can take. This is the set of values that the function returns after we enter an x value.
The given function is f(x) = -4|x + 1| − 5. Plot the function on the graph and it is observed that the range of the function varies from -∞ tp 5.
The graph of the function is attached with the answer below. The absolute function has the vertex at (-1,-5).
Therefore, the range of the function f(x) = -4|x + 1| − 5 is (-∞, -5). The correct option is A.

Answer: Z = 83
X = 7
Step-by-step explanation:
Z = 83 because the opposite side is also 83 and they are the same angle. X = 7 because the whole thing equals 360 and 83 +83 = 166 and 360 - 166 = 194 and 194 divided by 2 equals 97 and 15 x 7 - 8 = 97 and the other side is also the same because the angles are the same
