Which of the following is the solution to the equation 5/6 x= -1/6?
-1/5
1/5
-5
5
given f(x)=-x-1 find (6)
Answer:
[tex]{ \rm{f(x) = - x - 1}} \\ \\{ \rm{f(6) = - 6 - 1}} \\ \\ { \rm{f(6) = - 7}}[/tex]
Answer:
f(6) = -7
Step-by-step explanation:
It is given that x = 6. Plug in 6 for x in the given equation:
f(x) = -x - 1
f(6) = -(6) - 1
Note that when you are subtracting two negative numbers, you are really adding the two numbers:
f(6) = -(6) - 1
f(6) = -7
When x = 6, f(x) = -7

What is the distance between the points (1,6) and (-7,3) on a standard coordinate plane?
39
73
173
55
Step-by-step explanation:
I think you are missing the square root signs or so in the answer options.
the distance between 2 points is calculated by using Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse of the triangle and the distance between the points, which are the end points of the Hypotenuse.
a and b are the legs and enclose the 90 degree angle. they are the differences of the x and y coordinates between the 2 points.
so,
distance² = (1 - -7)² + (6 - 3)² = 8² + 3² = 64+9 = 73
=>
distance = sqrt(73)
The money used in Jordan is called the dinar. The exchange rate is $3 to 2 dinars. Find how many dollars you would recieve if you exchanged 22 dinars
Answer:
He would have received $33 if he exchanged 22 dinars
Step-by-step explanation:
In the equation 3x - 5 = 22,
where "x is the cost of a sandwich"
Diana said that "the sandwich cost $9."
Victor's answer is $5.
Who is right? Support your claim with math evidence or reasoning.
Answer:
Diana said that "the sandwich cost $9
Step-by-step explanation:
3x - 5 = 22
3x = 22 + 5
3x = 27
x = 27 / 3
x = 9

1 cup of mango and 3 cups of strawberries. And 2 cups of mango and 6 cups of strawberries are they equivalent
Answer:
Yes
Step-by-step explanation:
First off, let's use an example with the same equivalence:
[tex]\frac{12}{36} =\frac{16}{48}[/tex]
If you divide the denominator by the numerator you have to get 3, otherwise, it's not equivalent.
The constant of proportionality between the denominator and the numerator, if we use x and y, is:
[tex]y=3x[/tex]
So, just like the example and explanation I used, 3 divided 1 is 3 and 6 divided by 2 is 3.
Answer:
Yes, the 2 cups of mango and 6 cups of strawberries are equivalent.
Step-by-step explanation:
The question is based on ratios. Ratios are basically the quantitative relation between two amounts showing the number of times one value contains or is contained within the other. In this instance, you're altering the quantity by 2. So the 1 cup of mangoes becomes 2 cups of mangoes and the 3 cups of strawberries becomes 6 cups.
Another example of this could be:
In the store, for every 1 man there are 4 women. So if you change the amount of men in the store from 1 to 2, the quantity of women would go from 4 to 8.
Write the expression as a single logarithm.
log₄ 2x - log₄ 6y
Answer:
[tex]log_{4}(\frac{2x}{6y})[/tex]
Step-by-step explanation:
According to the Quotient Rule (Logarithmic Property):
[tex]log_{a}x - log_{a}y = log_{a}(\frac{x}{y})[/tex]
Therefore, you could combine the logarithmic expressions as:
[tex]log_{4}2x - log_{4}6y = log_{4}(\frac{2x}{6y})[/tex]
Optional:
If ever you're required to simplify it further, [tex]log_{4}(\frac{2x}{6y})[/tex] will be:
[tex]log_{4}(\frac{2x}{6y}) = log_{4}(\frac{x}{3y})[/tex]

How to solve 35 divided 10?
Answer:
Here we will show you step-by-step with detailed explanation how to calculate 35 divided by 10 using long division.
Before you continue, note that in the problem 35 divided by 10, the numbers are defined as follows:
35 = dividend
10 = divisor
Step-by-step explanation:
ywy
The solution to the expression 35 divided by 10 is 3.5
Given data:
The first number is represented as p.
The value of p = 35
The second number is represented as q.
The value of q = 10
Now, the expression is 35 divided by 10
So, [tex]A=\frac{p}{q}[/tex]
To solve 35 divided by 10, yu perform the division operation as follows:
Divide 35 by 10:
35 ÷ 10 = 3.5
Hence, 35 divided by 10 equals 3.5.

Answer: 3.5 years
Step-by-step explanation: Let A be the salaries earned from company A for x years and B for company B for the same years.
A = 31000 + n*3000
B = 38000 + n*1000
To find the case where A = b, set them to each other and solve for n, the number of years.
31000 + n*3000 = 38000 + n*1000
2000n = 7000
n = (7000/2000) = 3.5 years.

CAN ANYONE PLZ HELP ME WITH THIS WORKSHEET .. I’ll mark as brainliest
Answer:
Step-by-step explanation:
1)
We know that if [tex]x^2=9[/tex], then [tex]x=\pm \sqrt{9}[/tex], so [tex]\boxed{x=3,-3}[/tex]
2)
We know that if [tex]x^3=8[/tex], then [tex]x=\sqrt[3]{8}[/tex], so [tex]\boxed{x=2}[/tex]
3)
[tex]x^3=\frac{1}{8}[/tex] means that [tex]x=\sqrt[3]{\frac{1}{8}}=\frac{\sqrt[3]{1}}{\sqrt[3]{8}}=\frac{1}{2}[/tex].
So, [tex]\boxed{x=\frac{1}{2}}[/tex].
4)
[tex]x^3=27[/tex] means that [tex]x=\sqrt[3]{27}=\sqrt[3]{3^3}=3[/tex].
So, [tex]\boxed{x=3}[/tex].
5)
[tex]x^2=25[/tex] means that [tex]x=\pm \sqrt{25}=\pm \sqrt{5^2}=\pm 5[/tex].
So, [tex]x=5,-5[/tex].
6)
We know that the side length of the square will be [tex]\sqrt{\frac{9}{16}}=\frac{\sqrt{9}}{\sqrt{16}}=\boxed{\frac{3}{4}}[/tex].
7)
[tex]6x^2=54[/tex] means that [tex]x^2=9[/tex], which means that [tex]\boxed{x=3,-3}[/tex].
8)
[tex]2x^2+25=75[/tex] means that [tex]2x^2=50[/tex], which means that [tex]x^2=25[/tex], which means that [tex]\boxed{x=5,-5}[/tex]
