Answer:
Rate of change = -12
Step-by-step explanation:
y − 3 = −12(x + 4)
Expanding, we have;
y - 3 = -12x - 48
y = -12x - 48 + 3
y = -12x - 45
Now, formula for rate of change is;
Rate of change = (y(x + h) - y)/h
y(x + h) is; y = -12(x + h) - 45
This gives;
Rate of change = (-12(x + h) - 45 + 12x + 45)/h
Rate of change = (-12x - 12h - 45 + 12x + 45)/h
Rate of change = -12h/h
Rate of change = -12

A math test is made up of 7 problems each worth 10 points. There is no partial credit. Every test taker receives 30 points for taking the test. Enter a function to describe the test score determined by the number of correct answers. Then, graph the function.
f(x)=_____
Answer:F(x) = 10x+30
Step-by-step explanation:
X=3
The function which represents the test score determined by the number of correct answers is f(x) = 30 + 10x.
What is the linear equation in two variable?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.
According to the given question
We have
Total number of problems in a math test = 7
Total points given to each problem if it is correct = 10
Every text taker receives points for taking a test = 30
Let x represents number of correct answers given by the test taker and f(x) be the total score earned by the test taker.
Now, the function or linear equation in two variable which represent the given scenario is
f(x) = 30 + 10x
Hence, the function which represents the test score determined by the number of correct answers is f(x) = 30 + 10x.

Answer:
MP ⊥ LO ⇒ proved
Step-by-step explanation:
In the given figure
∵ m∠LPM = m∠MNO ⇒ given
∵ m∠MNO = m∠MPO ⇒ given
→ If the measure of an angle equals the measures of another two
angles, then the two angles must be equal in measures
∴ m∠LPM = m∠MPO ⇒ proved
∵ P ∈ line LO
∵ ∠ LPM and ∠MPO are adjacent angles
∴ ∠LPM and ∠MPO formed a pair of linear angles
→ The measure of the linear pair angles is 180°
∴ m∠LPM + m∠MPO = 180°
∵ m∠LPM = m∠MPO
→ That means the measure of each one is 180° divided by 2
∴ m∠LPM = m∠MPO = 180° ÷ 2
∴ m∠LPM = m∠MPO = 90°
∵ MP intersect LO at P and formed right angles at P
→ That means MP is perpendicular to LO
∴ MP ⊥ LO ⇒ proved

There are about 1.61 kilometers in 1 mile. Let LaTeX: xx represent a distance measured in kilometers and LaTeX: yy represent the same distance measured in miles. Write two equations that relate a distance measured in kilometers and the same distance measured in miles.
Answer:
1.61 x km= y miles
x km= y/ 1.61 miles
Step-by-step explanation:
Let x represent the distance in Kilometers and y represent the distance in miles then
1.61 x km= y miles
Now if we have 5 miles then
1.61(5) km = 5miles
8.05 km = 5 miles
Similarly if we want to express 1 km in miles the equation would be
x km= y/ 1.61 miles
So for 5 km the miles would be
5 km = 5/1.61 miles
5 km = 3.1055 miles

Find the equation of the linear function represented by the table below in slope-intercept form.
x: 0,1,2,3,4
y: -6,4,14,24,34
Answer:
y = 10x - 6
Step-by-step explanation:
If we know the function is linear then we can use any two coordinate pairs to find the slope of the line.
Note that the first pair is (0, -6) and the last pair is (4, 34). The 'run' is from x = 0 to x = 4, a 'run' of 4. The 'rise' is from -6 to34, a 'rise' of 40. Thus, the slope of this line is m = rise / run = 40/4 = 10.
Again using the coordinate pair (0, -6), along with the slope-intercept form of the equation of a straight line, we get:
-6 = 10(0) + b, so we know that b = - 6 and that the equation of this line must therefore be:
y = 10x - 6
The required slope-intercept form of the function is y = 10x - 6.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
m = (y₂ - y₁) / (x₂ - x₁)
Substitute 2 pairs from the table in the above equation,
m = (4 + 6)/(1-0)
m = 10
Now put the slope and one pair in the slope-intercept form of the equation
y - y₁ = m (x - x₁)
y + 6 = 10(x - 0)
y = 10x - 6
Thus, the required slope-intercept form of the function is y = 10x - 6

Circle A has a diameter of 8 inches, a circumference of 25.12 inches, and an area of 50.24 square inches. The diameter of circle B is 3 inches, the circumference is 9.42 inches, and the area is 7.065 square inches.
Part A: Using the formula for circumference, solve for the value of pi for each circle. (4 points)
Part B: Use the formula for area and solve for the value of pi for each circle. (4 points)
Part C: What observation can you make about the value of pi for circles A and B? (2 points)
The value of pi is about 3.14, and it is the same when using both the area and circumference.
How to calculate circumference?The circumference is given by:
Circumference = π * diameter
For circle A:
25.12 = π * 8
π = 3.14
For circle B:
9.42 = π * 3
π = 3.14
The area is :
Area = π * diameter² / 4
For circle A:
50.24 = π * (8²)/4
π = 3.14
For circle B:
7.065 = π * (3²)/4
π = 3.14
The value of pi is about 3.14, and it is the same when using both the area and circumference.

The bar that represents the bar that would be the largest in a histogram would be 2/15.
How to identify the bar that would be largest in a histogram?To identify the bar that would be the largest in a histogram we must take each of the options and perform the division to obtain a decimal number. Once we have all the decimal numbers, we must identify which is the largest of them and thus we will know which one would represent a larger bar in a histogram. Here is the procedure:
1 / 10 = 0.11 / 15 = 0.061 / 30 = 0.032 / 15 = 0.13According to the above, the one that represents a larger bar would be 2 / 15 = 0.13

Round 34.4678 of to two decimals
Answer:
34.47
Step-by-step explanation:
When you need to round it off to the second decimal, you must look at the 3rd decimal place.
In this case, it's 7. If it's a number greater than 5 or 5, you must round off to the next value and if it is less than 5 or 5.
Since it is 7 in the third decimal place, the answer would be 34.47
Answer:
34.47
Step-by-step explanation:
Round to the nearest thousandths place.=> 34.4678 [Unit place is 8, so it will round up.]
=> 34.468
2. Round to the nearest hundredths place.
=> 34.468 [Tens place is 8, so it will round up.]

Answer:
x = 57
Step-by-step explanation:
1. Look at the expression (x + 22). It's measurement the upper side of the lines. We know that if we add up all sides, we will get a full circle, or a value of 360. We know that if I extend the blue line to the left on the upper parallel line, it would equal 180 degrees.
We can express this as x + 22 = 180. Now lets look at the bottom equation, notice that the 2x - 13 is the missing side of x + 22. So we know:
x + 22 + 2x - 13 = 180
3x + 22 - 13 = 180
3x + 9 = 180
3x = 171
x = 57
2. We can check this by plugging it into our formula. x + 22 and 2x - 13. so 57 + 22 = 79 and 2(57) - 13 = 101. Add them together: 79 + 101 = 180.
3. We know this is true because both angles combined will be to form 180 degrees. For a better understanding, view the image I sent you. 1 = 3, and 4 = 2. Opposite angles are equal. In your equation, we have 3 and 8. we KNOW that 8 = 2. And we also know that adding up 2 + 3 MUST equal 180 degrees.

Jason had $6 in his lunch account at school on Monday. He spent $2 on lunch on Tuesday, deposited $7 on Wednesday and brought lunch from home. He bought lunch on Thursday for $5 and on Friday, he bought lunch again for $4. How much does Jason have on Friday AFTER he bought lunch?
Answer:
$2
Step-by-step explanation:
Credits:
Jason initial amount in his account = $6
Amount deposited for the week = $7
Total credit = $7+$6
Total credit = $13
Debit:
Cost of lunch bought on Tuesday = $2
Cost of lunch bought on Thursday = $5
Cost of lunch bought on Friday = $4
Total cost of lunch for the week = $2+$5+$4 = $11
Amount debited = $11
Balance left after he bought lunch on Friday = amount credited - amount debited
Balance = $13-$11
Balance = $2
Hence Jason had $2 balance left after buying his Friday lunch.

The school band is going to buy candy bars for $430 and sell them at school for $1.50 each. The band has to raise $1,350 to help pay for a trip. Write and inequality that represents how many candy bars x the band has to sell to make enough money for the trip.
Answer:
x = 900 or 1.50 * x = 1,350 (Though I advise you to use x = 900)
Step-by-step explanation:
Divide 1,350 by 1.50 to see that they need to sell exactly 900 bars. We can fact check by using a calculator to do the equation 1.50 * 900 = 1,350.
