Solve for x:2/5 (x - 2) = 4x
Answer:
x= -2/9
Step-by-step explanation:
2(x-2)/5=4x
2(x-2)=4x*5
2(x-2)=20x
x-2=20x/2
x-2=10x
-2=10x-x
9x= -2
x= -2/9

Explain how to determine if you have a direct variation or proportional relationship
given a graph
Answer:
straight line that passes through the origin
Step-by-step explanation:
Two variables are said to have a direct variation or proportional relationship if it can be represented by y = kx, where k is a constant.
Comparing this with the equation of a straight line y = mx + b, where m is the slope of the line and b is the y intercept (value of y when x = 0), We can tell if the say that the graph of a direct variation or proportional relationship is a straight line with no y intercept (b = 0, that is it passes through the origin).
How many moles of mercury, Hg is in a sample of 505 grams?
Answer: 2.52Hg
Step-by-step explanation:
First and foremost, we should realize that:
1 moles Mercury = 200.59 gram
Therefore, the number of moles of mercury, Hg is in a sample of 505 grams would be calculated as:
= 505/200.59
= 2.52
Given a polynomial f(x), if (x + 5) is a factor, what else must be true?
f(0) = 5
Ob
f(0) = -5
Ос
f(5) = 0
Od
f(-5) = 0
Answer:
As
[tex]p(-5) = 0[/tex]
Thus, the correct option is 'd'.
Step-by-step explanation:
We know that the special theorem of remainder states that:
if
[tex]x-k[/tex] is a factor of [tex]p(x)[/tex]
then
[tex]p(k) = 0[/tex]
so
[tex]x+5 = x-(-5)[/tex]
[tex]k = -5[/tex]
Thus,
[tex]p(k) = 0[/tex]
[tex]p(-5) = 0[/tex]
Thus, the correct option is 'd'.

5x-3>7 or -2x+4>6 inequality solution
Answer:
its 83
Step-by-step explanation:
A jar contains 3 blue marbles, 7 red marbles, and 5 green marbles. you pick one without looking. whats the probability that the marble will not be red?
Probability of not picking up a red marble = 8/15
No of red marbles = 7
No of green marbles = 5
No of blue marbles = 3
Total sample space = 3+7+5 = 15 marbles
Probability of picking out blue marble = 3/15
Probability of picking out red marbles = 7/15
Probability of picking out green marbles = 5/15
Probability of not picking up a red marble = 1 - 7/15 = 8/15

Answer:
4/8 in simplist for would be 1/2
Step-by-step explanation:
Evaluate f(x) = 5* when x = -3.
If you're trying to say find f(x) = 5ˣ when x = -3
The answer would be [tex]\frac{1}{125}[/tex]
A negative exponent means to put that value in the reciprocal. So the reciprocal of 5 is [tex]\frac{1}{5}[/tex] . and the 3 means to multiply it 3 times like [tex](\frac{1}{5})(\frac{1}{5})(\frac{1}{5})[/tex] to get [tex]\frac{1}{125}[/tex]

a -foot piece of string is cut into two pieces so that the longer piece is longer than twice the shorter piece. find the lengths of both pieces.
The length of longer piece is 2L/3 and shorter piece is L/3;
Let the length of string be 'L';
Let the longer piece be 'L₁' and shorter piece be 'L₂';
L₁ + L₂ = L; -(i)
According to question;
L₁ = 2L₂; -(ii)
Using (ii) in (i);
3L₂ = L;
L₂ = L/3;
L₁ = 2L/3;

Thank You!!!
Answer: B and C
Step-by-step explanation: To start off, you subtract 3 from both sides, to get 4<z/2, then multiply both sides by 2, you get z>8. Now it's greater than 8, so it can't equal 8, so the answers would be B and C, since they are both greater than 8, and you have to select multiple choices.

if the diameter of a circle double, the circumference of the larger circle is how many times the circumference of the original circle?
The circumference of the larger circle is 2 times the circumference of the original circle.
What is the circumference and area of a circle?Let r be the radius of the circle.
Then the area of the circle will be
A = πr² square units
The circumference of the circle will be
C = 2πr units
If the diameter of a circle doubles, the circumference of the larger circle.
Let d be the diameter of the circle.
Then the diameter of the small circle is d and the diameter of the other circle is 2d.
Then the ratio of the circumference of the circles will be
⇒ 2πr₂ / 2πr₁
⇒ 2r₂ / 2r₁
⇒ 2d / d
⇒ 2
The circumference of the larger circle is 2 times the circumference of the original circle.
