Given
f(x) = - x² - 9x - 7
f(3) = -( 3) ² - 9 * 3 - 7
= - 9 - 27 - 7
= -43
Hope it will help :)
f(3) = -(3)^2 - 9(3) - 7
f(3) = -43

What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related. They can answer geometrical problems because it gives them geometrical aspects of algebra. In this area of geometry, a pair of ordered numbers is used to describe the location of points on a plane.
As per the given data:
Coordinates of point V = (3, -7)
Rotation to be given = 180° (clockwise)
For drawing the image of point V (3, -7):
Step 1: Draw a line passing through the origin and V (3, -7) extending through 2nd and 4th quadrant.
Step 2: Change sign of x and y coordinates as rotation is of 180° and mark the point in the 2nd quadrant.
Image of the point V is V' = (-3, 7) as shown in the graph below.
Hence, the image of the point V is V' = (-3, 7).

A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45. Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42. What is the value of each grocery coupon and each drug store coupon?
Answers
Answer:
The value of each grocery store coupon is $6
Then the value of each drugstore coupon is $3.
Step-by-step explanation:
Let's define:
G = value of a grocery store coupon.
D = value of a drugstore coupon.
We know that:
"A welcome kit contains 3 grocery store and seven drugstore coupons. The coupons are worth $45"
We can write this as:
3*G + 7*D = $45
And we also know that:
"Another welcome kit contains three grocery store coupons and six drugstore coupons worth $42"
We can write this as:
3*G + 6*D = $42
Then we have the system of equations:
3*G + 7*D = $45
3*G + 6*D = $42
To solve this, we can isolate the term "3*G" in one of the equations (because it appears on both of them)
Let's isolate it on the second equation:
3*G = $42 - 6*D
Now let's replace this on the first equation:
($42 - 6*D) + 7*D = $45
$42 + D = $45
D = $45 - $42 = $3
Then the value of each drugstore coupon is $3.
And we also have the relation:
3*G = $42 - 6*D
We can just replace the value of D to get:
3*G = $42 - 6*$3 = $42 - $24 = $18
G = $18/3 = $6
The value of each grocery store coupon is $6
Common factor between 6 and 15

If each unit on the grid represents 300 miles, what is the approximate distance between Phoenix and Atlanta?
Explain how you could find the distance between a point and its reflection across the y-axis.
Answers
Answer:
I think it is 150 miles between Phoenix and Atlanta
Step-by-step explanation:
(2.9,-4.2)-(2.4,-4.2)=(0.5,0)

When placed near a second charge, a 60-μC charge experiences a force of 0.30 N. What is the electric field strength at the location of the 60-μC charge? What is the strength of the electric field at the location of the test charge?
Answers
Answer:
[tex]E=5000N/C[/tex]
Step-by-step explanation:
From the question we are told that
Charge [tex]q= 60 \mu C[/tex]
Force [tex]F_=0.30N[/tex]
Generally the equation for electric field strength is mathematically given as
[tex]E=F/q[/tex]
[tex]E=\frac{0.30}{60*10^-^6}[/tex]
Therefore
[tex]E=5000N/C[/tex]

for a person who understands natural logs (ln) vs logs. Why do we use (ln) to inverse an equation when there is no e in the original equation?
Answers
Answer:
Because e is used so commonly in math and economics, and people in these fields often need to take the logarithm with a base of e of a number to solve an equation or find a value, the natural log was created as a shortcut way to write and calculate log base e. ... So ln(x) = loge(x). As an example, ln(5) = loge(5) = 1.609.

The number of cell phones that employees at a factory can assemble is directly proportional to the number of hours the employees spend assembling cell phones. The employees can assemble 1,576 cell phones in 8 hours. If these employees continue to work at the same rate, how many cell phones will they assemble in 53 hours?
Answers
Answer:
10,441
Step-by-step explanation:
The number of cell phones the employees can assemble in 53 hours will be 10441.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
1,576 cell phones in 8 hours.
Number of cell phones sells per hour or rate of change,
1576/8 = 197 cell phones/hour.
The number of cell phones sells in 53 hours,
197 cell phones/hour x 53 = 10441 cells phones.
Hence "The number of cell phones the employees can assemble in 53 hours will be 10441".

Igor and sally both tan the same distance. Igor completed The distance in two hours. His average speed was 6 mph. Sally completed the distance in four hours. What with Sally is average speed for the journey? Give your answer in miles per hour
Answers
Answer: 3mph
Step-by-step explanation:
Speed is calculated as Distance/Time.
Igor's distance = Speed × Time
= 6 × 2
= 12m
Since they ran same distance, Sally also ran 12m
Sally's speed = Distance/Time
where,
Distance = 12m
Time = 4 hours
