Answer:
C. log7 36....................................
The given logarithmic expressions together can be written as log₇ 36
What is a logarithmic function ?The logarithmic function is an expression which we can write as, y = logₐx, where a>0 & x>0, It is the inverse of exponential function.
Formulae for logarithmic function are,
LogAB = LogA + LogB
Logₐaᵇ = b
Given that,
= log₇(2 x 6) + log₇3
= log₇ 36
We have the result
log A + log B = log AB
Here the question is log₇(2 x 6) + log₇3.
Using the property of logarithm we will get,
= log₇(2 x 6) + log₇3
= log₇(2 x 6 x 3)
= log₇ 36
So, log₇(2 x 6) + log₇3 = log₇ 36

Answer:
f(-2) = 2f(0) = 4Step-by-step explanation:
a) Locate the point -2 on the x-axis. Follow the line up until it meets the blue curve. Follow that grid line to the right to see where it meets the y-axis. It is y=2. That means f(-2) = 2.
__
b) Locate y=4 on the y-axis. Notice that the curve intersects the y-axis there, so x=0.
x = 0 is the only value of x for which f(x) = 4.
will a one variable equation always have only one solution
Answer:
Every linear equation that is a conditional equation has one solution. However, not every linear equation in one variable has a single solution. There are two other cases: no solution and the solution set of all real numbers. ... Therefore, the equation is always true.
Step-by-step explanation:
We want to see if a one-variable equation always has only one solution.
This is false, as one-variable equations can have no solutions or more than one solution.
So we start with the statement:
"A one-variable equation always has only one solution".
We need to find a counterexample to prove that this is false, and there are really easy counterexamples, like:
x^2 - 4 = 0
This is a one-variable equation, and solving it we have:
x^2 = 4
x = ± √4 = ±2
So here we have two solutions, 2 and -2, thus the statement is false.

The length of a bed would be about
Answer:
2 yards.
Step-by-step explanation:
We know that a length of a bed is DEFINITELY not 2 miles, and it isn't 2 inches either, because they're both too big and too small. However, 2 feet is also pretty small, too, because 2 feet is about the size of a crib. So what's left is 2 yards, so a bed is about 2 yards.
Answer:
2 yards
Step-by-step explanation:
The question is asking what the length of a bed would be.
To answer this question, it's basically common sense, how long is a bed usually, it would be about 5 to 10 feet, big enough to fit a human with no uncomfortability.
So with this info, we can scratch D and B. As for A and C, let's convert them into feet.
1 yard equals 3 feet, meaning two yards would be 6 feet.
1 mile is 5280 feet, this is obviously wrong.
A is our answer.

Estimate 0.95% of 700
Answer:
6.65
Step-by-step explanation:
0.95% of 700
= 0.0095*700
= 6.65
The value of 0.95% of the number 700 is 6.65.
The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the number 700 is 0.95%. The number will be calculated as below,
Number = 0.95% of 700
Number = 700 x 0.95/100
Number = 6.65
Therefore, the value of 0.95% of the number 700 is 6.65.
