plzzzzzz help meeeee
Answer:
Step-by-step explanation:
For A, 7x=21, it is asking, 7 multiplied by what number is 21? We can try to figure it out. Let's start with 0.
7(0)≠21
Then 1.
7(1)≠21
7(2)≠21
7(3)=21
Therefore, for question a, the answer is 3.
For question b, it's asking 6 minus what is 2.
With this one, we can say it is 4, since 6-4=2.
Now moving on to B.
a) 2x+4=16
We need to isolate x in order to find it's value.
So we can begin with subtracting 4 from both sides, getting us:
2x=12
Then, if we divide both terms by 2, we get x.
x=12/2
x=6.
b)
3 x (z/4)=9
Again, we need to isolate z.
So, we multiply both sides by 4, getting us
3z=36
then we divide by 3
z=36/3
z=12
c) 16-x=2
Here we simply subtract 16 from each side, then flip the signs to get positive x.
So, 16-x=2
-x=-14
x=14
d) 4k=20
This is essentially asking, 4 times what number is 20?
So we can divide both sides by 4 and get
k=20/4
k=5

Answer:
25 ft^2
Step-by-step explanation:
In direct variation, if y varies directly with x, then the equation has the form
y = kx,
where k is the constant of proportionality. y is proportional to x.
Let's call the area y and the distance x.
Here, the area varies with the square of the distance, so the equation has the form
y = kx^2
Here, y is proportional to the square of x.
We can find the value of k by using the given information.
y = kx^2
When x = 20 ft, y = 16 ft^2.
16 = k(20^2)
k = 16/400
k = 1/25
The equation of the relation is:
y = (1/25)x^2
Now we use the equation we found to answer the question.
What is y (the area) when x (the distance) is 25 ft?
y = (1/25)x^2
y = (1/25)(25^2)
y = 25
Answer: 25 ft^2

Find the inverse function in slope-intercept form (mx+b)
f (x) = x - 16
f^-1 (x) =
Answer:
[tex] \rm y = x + 16 [/tex]
Step-by-step explanation:
A function is given to us and we need to write the inverse of the function in slope intercept form . The given function is ,
[tex]\rm\implies f(x) = x - 16 [/tex]
Let ,
[tex]\rm\implies y = f(x)[/tex]
So that ,
[tex]\rm\implies y = x - 16 [/tex]
Interchange x and y ,
[tex]\rm\implies x = y - 16 [/tex]
Solve for y ,
[tex]\rm\implies y = x + 16[/tex]
Now replace ,
[tex]\rm\implies y = f^{-1}(x) [/tex]
We have ,
[tex]\rm\implies f^{-1}(x) = x+16 [/tex]
And in slope intercept form ,
[tex]\rm\implies \boxed{\pink{\frak {y = x +16}}}[/tex]

Choose the correct description of the graph of the compound inequality: (5 points) 3x + 1 > 7 and 4x less than or equal to 24
Answer:
A number line with an open circle on 2, a closed circle on 6, and shading in between
Step-by-step explanation:
Given:
3x+1 > 7 → inequality A
4x ≤ 24 → inequality B
Step 1
Solve inequality A
3x+1>7
3x>7-1
x>2
the solution is the interval------> (2,∞)
Step 2
Solve inequality B
4 x ≤ 24
4 ≤ 6
the solution is the interval------> (-∞,6]
Step 3
Find the solution of the compound inequality
Solution A ∩ Solution B
(2,∞) ∩ (-∞,6]=(2,6]
therefore
The answer is A number line with an open circle on 2, a closed circle on 6, and shading in between
Answer:
Your answer would be a number line with an open circle on 2, a closed circle on 6, and shading in between.
Step-by-step explanation:
i.e. it could also be written as:
3x + 1 > 7
3x > 7 - 1
3x > 6
x > 2
And the second inequality is:
4x < 24
4x < 6
Hence, the compound inequality could be represented as:
x>2 i.e. (2,∞)
and x≤6 i.e. (-∞,6]
Hence, the feasible region or the region that is common to both the inequalities is:
(2,6]
Hence, there will be a number line with open circle at 2 since 2 is not included in the domain and a closed circle at 6 and shading in between

Answer:
4 + y < 6
see attached for a graph
Step-by-step explanation:
The English description "the sum of A and B" is written symbolically as ...
A + B
The symbol for "is less than" is <.
Then "the sum of 4 and y is less than 6" will be written ...
4 + y < 6
__
The solution to this is found by subtracting 4 from both sides of the inequality:
4 +y -4 < 6 -4
y < 2 . . . . . . . . . simplified solution
The graph of this is a number line with an open circle at y=2, and shading to the left of that point, where values on the number line are less than 2.
true or false, when graphing a linear Inequality in two variables, the inequality symbol " < " states to use a broken line.

Answer:
The answer is 2/9
Step-by-step explanation:
I got it right on the test
p(x) = 3(x + 10x + 5) - 5(x - k)
In the polynomial p(x) defined above, k is a
constant. If p(x) is divisible by x, what is the value
of k?
First, you should simplify the function expression.
3(x2 + 10x + 5) - 5(x-k) = 3x2 + 30x + 15 - 5x + 5k = 3x2 +15x +15 +5k
In order for the polynomial to be divisible by x, all terms need to divide by x with no remainder. The first two terms clearly divide by x. However, the last two do not. In order for this to work out where k is constant, 5k would have to cancel out the +15 term, leaving nothing to divide by x.
So: 15 + 5k = 0
5k = -15
k = -3
