The slope of -6 means that the battery reduces by 6% each hour
What is the linear equation?
Linear equations are the equations of degree 1. It is the equation for the straight line. The standard form of linear equation is ax+by+c =0, where a ≠ 0 and b ≠ 0.
The slope of -6 means that, the battery reduces by 6% each hour and the equation is B = -6t + 48
The points
The points on the graph are represented using the following ordered pair (1, 42) and (5,18)
The slope
Start by calculating the slope (m) using:
m = (B2 - B1)/(t2 - t1)
So, we have:
m = (18 -42)/5-1
m = -24/4
m = -6
The equation
The equation is then calculated as:
B = m(t - t1) + B1
This gives
B = -6(t - 1) + 42
B = -6t + 6 + 42
B = -6t + 48
Hence, The slope of -6 means that the battery reduces by 6% each hour

Explain how you can compare the cost of two items that are different sizes.
Answer:
You could compare the ounces or weight, the price per unit, or overall quality.
Step-by-step explanation:
You could use the ounce/weight to check which weighs more, or has more in it. Then figure out which is more reasonable. You could use the price per unit, and the ounce/weight because the price per unit/ price per ounce could be more expensive, or less expensive and make more sense to buy. Or you could just use overall quality. You can have an item with more in it, but have lower quality contents, when you could have a smaller amount with better quality contents, which might cost a little more.\

How do you determine the coordinates of a point after a reflection in the y-axis?
The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.
A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.
When a point is reflected across the Y-axis, the Y-coordinates remain the same, and the X-coordinates are transformed into their opposite signs.
Therefore, the reflection of the point (x, y) across the Y-axis is (-x, y).
A reflection of a point, a line, in the Y axis reflects the image over the Y axis to create a mirror image. In this way, the Y axis would be called the axis of reflection.

What is the height of a triangle if its base is 24 cm and its area is 216 cm2?
The height of a triangle is calculated to be 18 cm if its base is 24 cm and its area is 216 cm².
Given that,
Base = 24 cm
Area = 216 cm²
Height = ?
The formula to find out the area of the triangle is given by,
Area A = 1/2 × Base b × Height h
A = 1/2 × b × h
Making h as subject, we have,
h = (2 A)/b = (2× 216)/24 = 18 cm
Thus, the required height of a triangle is calculated to be 18 cm if its base is 24 cm and its area is 216 cm².

Your answer Daryl finds a pair of pants for $17.00. If the pants are on sale for 35% off, what is the sale price of the pants?
Answer:
$11.05
Step-by-step explanation:
First, you make the percent into a decimal
35% - 0.35
Next, you multiply 17 and 0.35
17* 0.35= 5.95
Then, you subtract the discount which is $5.95 from $17
17-5.95= 11.05
So, the answer is $11.05
Hope this helps :)
Answer: $11.05
Step-by-step explanation:
First how much 35% of 17:
35% = 0.35
0.35 x 17 = 5.95
Next, subtract this discount off of the total:
17 - 5.95 = 11.05
Now adding the dollar sign makes it $11.05

Select the correct answer. What is the slope of the line represented by this equation? -3x + 8y = 12 a. B. C. D.
With the help of the given equation, we know that the required slope is (A) 3/8.
What is a slope?In math, the gradient of a line is a number that tells you how steep it is and in which direction it goes in.
The point-slope form is a way of writing equations (y-y₁=m(x-x₁)) to emphasize the slope and a point on the line that isn't the y-intercept.
To highlight the same line's slope and y-intercept, you can rewrite the equation in slope-intercept form (y=mx+b).
So, we have the equation:
-3x + 8y = 12
Calculate the slope as follows:
We need to change it into a more general format.
-3x+8y=12
⇒ 8y = 3x+12
⇒ y = 3x/8+12/8
⇒ y = 3x/8+3/2
If you look at it in terms of y = mx+c, the m would be 3/8.
Therefore, with the help of the given equation, we know that the required slope is (A) 3/8.

So the possible values of (z+1/z) are 6 and 0 for z=5 and z=-1 respectively.
Define Algebric expression.An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.
What is variables and constants ?A constant has a fixed value and does not vary over time. For instance, the size of a shoe, a piece of clothing, or any other article of clothing will never alter. x+y = 8 is an algebraic equation, and 8 is a constant that cannot be altered. Variables are concepts that change or fluctuate throughout time.
We can start by multiplying both sides of the equation by (z+1/z) to get:
(z-1/z)(z+1/z) = 6(z+1/z)
This simplifies to:
z^2 - 1 = 6z + 6
We can then solve for z by isolating it on one side of the equation.
z^2 - 6z - 5 = 0
(z-5)(z+1) = 0
So the solutions to this equation are z = 5 and z = -1
Now we can substitute the value of z back into the original expression to find the value of (z+1/z)
For z = 5, (z+1/z) = (5+1/5) = 6
For z = -1, (z+1/z) = (-1+1/(-1)) = 0
So the possible values of (z+1/z) are 6 and 0.

How to express ratio in simplest form?The United States Department of Transportation Federal Highway Administration said that the average driver traveled 12,724 miles in 2020. That's down from 14,263 average annual miles in 2019. The 2020 average equates to 1,060 miles per month per driver, or about 35 miles per day.Although it's possible, you cannot drive 1000 miles in a day safely with a single driver. This would involve approximately 16 hours of driving before accounting for traffic and rest stops. Assuming a total travel time of 20 hours, you would need to depart in the early hours and share the driving.Often, 100,000 miles is considered a cut-off point for used cars because older vehicles often start requiring more expensive and frequent maintenance when mileage exceeds 100,000.The average American spends 18 days driving per year, with an average of eight hours and 22 minutes per week, a OnePoll study conducted on behalf of Cooper Tire found.Number of miles driven by each person in a week:
Valeria = 7
Taub = 21
Ruby = 35
Number of miles driven by Taub : Number of miles driven by Valeria
