Answers
Answer:
Option d) : Neither A nor BStep-by-step explanation:
To determine if it is a function, check if any x value repeated. For it to be a function, every x value should only be paired with one value
In both the table you can see that values are paired with more than one value meaning they aren't function...

If the perimeter of a square is 4x - 24, what is the
area of the square?
Answers
Answer:
A = (x - 6)² sq. units or
A = (x² - 12x + 36) sq. units
Step-by-step explanation:
P = 4s, where s is the side.
4s = 4x - 24
s = x - 6
A = s²
A = (x - 6)² sq. units or
A = (x² - 12x + 36) sq. units

Caesar gets coffee from his local coffee shop when he has time in the morning. The coffee shop sells a ceramic refill mug for $8.95. Each refill costs $1.50. Last month Caesar spent $26.95 on a mug and refills.
Write an equation that you can use to find the number of refills Caesar purchased.
a.8.95r + 1.50= 26.95
b.8.95 + 1.50r= 26.95
c8.95 + 1.50 = 26.95r
How many refills did he buy? Solve the equation
Answers
Now we going to solve it
To find how many refills he bought
8.95 + 1.50(r) = 26.95
-8.95 = -8.95 1. subtract $8.95 from
———————————- both sides.
1.50(r) = 18.00 2. The $8.95 cancels
——— = ——— out.
1.50 1.50 3. Bring the equation
R = 12 down.
4. Now you divide 1.50
on both sides.
Final answer R= 12

For a data consisting of 9 observations, the sum of 9 values is 360 and the sum of squares of deviation taken from the mean is 288. Find the mean and variance of the observation.
Answers
Answer:
4 ; 32
Step-by-step explanation:
Given that :
Number of observations, n = 9
Let observations = X
ΣX = 360
The mean, (m) is calculated using the formula :
m = ΣX / n
m = 360 / 9
m = 4
Σ(X - m) = 288 (sum of square of deviation )
Variance is calculated using the formula :
[Σ(X - m) / n]
Variance = Sqrt(288 / 9)
Variance = 32

The length of a planet's orbit around a star is approximately 29,870,000 km.
It takes the planet about 1670 Earth days to complete a full orbit.
What is the planet's average speed in kmh-' to 3sf?
Answers
Answer:
745 k/hr
Step-by-step explanation:
mathematically, 1 day = 24 hours
1670 days = 1670 * 24 = 40,080 hours
The speed is thus;
(29,870,000)/40,080 = 745.259
= 745 km/h

Jasmine is buying cakes for a party. One chocolate cake costs $7, and one lemon cake
costs $5. If Jasmine needs to buy 18 cakes and has $110 to spend, how many lemon
cakes can she buy?
Set up and solve a system of linear equations to model how to determine the number
of lemon cakes Jasmine can buy for the party.
Answers
Answer:
Step-by-step explanation: Am not sure if this is the answer you guys are looking for but my in 9th grade and this is how my math teacher taught me how to do it.
one chocolate cake=?=x
one lemon cake=?=y
$270 spent
need to buy total of 18 cakes
1-chocolate cake =$7
lemon cake = $5
cakes 18=x+y
money $110=$7x+$5y
When i graphed it on the demos calculator i got (10,8).
So 10= the number of chocolate cake brought and 4= the number of lemon cake brought
At a local gardening store, there is a small group of plants located near the gardening
supplies, and the remainder of the plants are arranged in equal-sized rows in the field
behind the store. The function 9(x) = 18x+23 represents the total number of plants at the
gardening store if there are x rows of plants in the field. What is the value of g(27)), the
total number of plants when there are 27 rows?
Answers
Answer:
uuuuuuuuu
Step-by-step explauuuuuuuuuuu
The required number of plants from the function is 509 when there are 27 rows.
Given that,
The function g(x) = 18x+23 represents the total number of plants at the gardening store if there are x rows of plants in the field. What is the value of g(27) is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Number of plants,
g(x) = 18x+23
Since the number of rows is 27
Now, the number of plants,
g(27) = 27 * 18 + 23
g(27) = 486 + 23
g(27) = 509
Thus, The required number of plants from the function is 509 when there are 27 rows.

£600 is invested into a savings account paying
5% compound interest per year. How much is in
the account after three years
Answers
Answer:
£694.575
Step-by-step explanation:
Using the formula for calculating the compound interest expressed as;
A = P(1+r)^t
P is the principal = £600
r is the rate = 5% = 0.05
t is the time = 3 years
Substitute into the formula;
A = 600(1+0.05)^3
A = 600(1.05)^3
A = 600(1.157625)
A = 694.575
hence the amount in the account after 3 years is £694.575
