Find the slope of the line that passes through (4,7) and (1,8)
1. Identify the slope and y-intercept of the following equation: y = 9x - 3
Answer:
Step-by-step explanation:
Hey :)
Keep in mind:
y = mx + b
Where m = slope and b = y-intercept
Since we are told:
y = 9x - 3
This means m = 9 and b = -3
Therefore the slope is 9 and y-intercept is at (0,-3)

what inequality represents each verbal expression?
a. all real #'s x greater than 2
b. 6 more than a # k is less than or equal to 12
Answer:
I think the answer is B
Step-by-step explanation:
The inequality that represents "all real number's 'x' greater than 2" is [tex]x > 2[/tex] and the inequality that represents "6 more than a number 'k' is less than or equal to 12" is [tex]6 + k \leq 12[/tex].
a)
Given :
All real number's 'x' greater than 2
So, the inequality that represents the given verbal expression is given below:
[tex]x > 2[/tex]
where 'x' is the real number.
b)
Given :
6 more than a number 'k' is less than or equal to 12.
So, the inequality that represents the given verbal expression is given below:

A number is written with a base and an exponent. What is
another name for the exponent?
-rational number
-base
-exponent
-power
Answer:
power
Step-by-step explanation:
The another name for the exponent is power, the correct option is D.
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
Given;
A number is written with a base and an exponent
Now,
n exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself and exponent is also called index or power.
Therefore, the answer will be exponent.

Fuji apples grown at a certain orchard have a mean weight of 5.2 ounces with a standard deviation of 0.8 ounces. Suppose the scale the orchard owner uses systematically underweighs apples by 0.2 ounces and also weighs the apples in grams, rather than ounces. What would the mean and standard deviation of these apples' weights be as determined by this scale? (Note: 1 ounce ≈ 28 grams).
Answer:
Mean 140 grams
Standard deviation 22.4 grams
Step-by-step explanation:
What would the mean and standard deviation of these apples' weights be as determined by this scale? (Note: 1 ounce ≈ 28 grams).
Mean = 5.2 ounces.
First step would be to convert from ounces to grams
1 ounce = 28 grams
5.2 ounces =
5.2 ounces × 28 grams
= 145.6 grams
He underweighs by 0.2 ounces
We convert this too
1 ounce = 28 grams
0.2 ounce =
0.2 ounce × 28 grams
= 5.6 grams.
The new mean weight of the Fuji apples is grams = 145.6 grams - 5.6 grams = 140 grams.
Standard Deviation = 0.8 ounces.
Even though he underweighed that apples by 0.2 ounces, there has minimal effect on the standard deviation of the apples.
Hence, the standard deviation if the apples in grams =
1 ounce = 28 grams
0.8 ounce =
0.8 ounce × 28 grams
= 22.4 grams

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.
