Write a linear function f with f(0)=3 and f(−6)=3
Answer:
y = 3
Step-by-step explanation:
Slope = 0/-6 = 0
y-int. = 3
The linear function [tex]f[/tex] with [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex] is [tex]y = 3[/tex].
Given two distinct points on cartesian plane, we can determine the linear function associated to those points as follows:
[tex]y = m\cdot x + b[/tex] (1)
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] (2)
[tex]b = y_{1}-m\cdot x_{1}[/tex] (3)
If we know that [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex], then we have the linear function below:
[tex]m = \frac{3-3}{0-(-6)}[/tex]
[tex]m = 0[/tex]
[tex]b = 3 - 0\cdot (0)[/tex]
[tex]b = 3[/tex]
The linear function [tex]f[/tex] with [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex] is [tex]y = 3[/tex].

What is the value of x in the equation x + 5.1 = 0
Answer:
-5.1
Step-by-step explanation:
x + 5.1 = 0
- 5.1 -5.1
x + 0 = -5.1
x = -5.1
The value of x is -5.1
Given,
x + 5.1 = 0
We need to find the value of x.
How do we find the value of a variable in an expression?We always keep the required variable on one side and keep all the other variables on the other side of the equation.
Example:
x + b + n = 2 + 2x
We need to find x.
Since we have two x terms
We will keep both the terms on one side.
b+ n - 2 = 2x - x
2x - x = b + n -2
x = b + n - 2 is our x value.
We have,
x + 5.1 = 0
Subtracting 5.2 on both sides.
x + 5.1 - 5.1 = 0 - 5.1
x = - 5.1
Thus the value of x is -5.1

The question is incomplete. Here is the complete question.
the batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius. what is the batting thermal conductivity when w/cm•c
Given
K = 0.03W/m°C
Required
Convert K to W/cm°C
Since 1m = 100cm,
K = 0.03w/1×100cm°C
K = 3×10^-2w/10² cm°C
K = 3 × 10^-2w/10² cm°C
K = 3w× 10^{-2-2}cm°C
K = 3w×10^-4cm°C
K = 0.0003w/cm°C
Answer:
0.0003
Step-by-step explanation:
DID IT ON KHAN
and Since 1m = 100cm,
K = 0.03w/1×100cm°C
K = 3×10^-2w/10² cm°C
K = 3 × 10^-2w/10² cm°C
K = 3w× 10^{-2-2}cm°C
K = 3w×10^-4cm°C
K = 0.0003w/cm°C

The graph represents the rate of two machines that fill water barrels. One machine has already filled 30 water barrels before the faster machine starts. According to the graph, the two machines will have filled a certain number of water barrels at about the same time. What is that number of barrels?
A) 45 barrels
B) 50 barrels
C) 80 barrels
D) 90 barrels
According to the graph, the number of barrels that the two machines would have filled at about the same time is; Option B; 50 Barrels
We are told that;
- Two machines fill water barrels
- One machine had filled 30 barrels before the faster machine started
- At a certain tile, they would have filled a number of water barrels at about the same time.
Now, from the graph, we see that;
The red line indicates the slower machine while the blue line indicates the faster machine.
Thus, the number of barrels they would have filled at about the same time is the number of barrels that corresponds to the point where both lines intersect each other.From the graph, the number of barrels at intersection point is 50 barrels.

a common mistake people make when working with exponents is to multiply the base by the exponent instead of raising the base to the power of the exponent. For instance, they would mistakenly say that 2^3 is 6 (because 2x3=6) when the correct answer is actually 8 (2x2x2=8) are there any pairs of numbers for which this mistake in thinking actually gives the correct answer? In other words are there any solutions to the equation a^x=a X what are the?
Answer:
The pair of number are (2 and 1), (2 and 2)Step-by-step explanation:
The pair of number that makes the expression [tex]a^x = ax[/tex] true are 2 and 2 as shown:
where a = 2 and x =2
2² = 2*2
2² = 4
and:
2*2 = 4
Hence 2² = 2(2) = 4 making the expression [tex]a^x = ax[/tex] true for both pair of numbers
Also the number pair 1 and 2 makes the expression correct as shown:
[tex]2^1 = 2(1)\\2 = 2 (true)[/tex]

Martin is an after school math tutor . He noticed that 6 people still needed help on 2/5 of the tutoring session time was left.Scince each person was given an equal amount of time, martin wrote the expression below to find the fraction or the toutoring session each person who still needed help would be allotted. 2/5 divided by 6 which expression is equivalent to martins expression?
Answer:
6/15 ÷ 6
Step-by-step explanation:
Martin is an after school math tutor
He noticed that 6 people still needed help on 2/5 of the time that was left
Martin wrote the expression
2/5 ÷ 6
This expression can be used to determine the number of persons who still need help
Therefore the expression that is equivalent to Martin's expression is
= 6/15 ÷ 6
Using 3 to divide both 6 and 5 will give
2/5 ÷ 6
Hence the expression which is equivalent to Martin's expression is 6/15 ÷ 6
