constant of proportionality: 2equation is: c = 2a==================================================
Explanation:
a = number of apples purchased
c = cost in dollars
The equation is in the form c = ka, where k is the constant of proportionality. It tells us what to multiply 'a' by to get the cost c. In more realistic practical terms, the value of k is the cost per apple (aka unit cost).
To find this unit price, we divide the given price by the given number of apples: k = c/a = 28/14 = 2. Each apple is $2. The constant of proportionality is 2.
We'll update the equation from c = ka to c = 2a
Note that if we bought a = 14 apples, then it costs us c = 2a = 2*14 = 28 dollars as expected.
Answer:
c=2a
Step-by-step explanation:
c=2a

A line passes through the point (0, -3/2) and has a slope of 1/2. what is the eqaution of the line?
Answer:
y = 1/2x - 3/2
Step-by-step explanation:
We apply our knowledge of slope intercept form:
y = 1/2 x + b
therefore, we plug in the values for x and y getting
-3/2 = 0 + b
so b = -3/2, plug it back into the equation getting
y = 1/2x - 3/2

Does this graph represent a function? Why or why not?
D. Yes, because it is a curved line.
O A. No, because it fails the vertical line test.
• B. No, because it is not a straight line.
O C. Yes, because it passes the vertical line test.
Answer:
c
Step-by-step explanation:
C, because a vertical line will only hit the function on one point at a time.
Answer:
C. Yes, because it passes the vertical line test.

Answer:
Step-by-step explanation:
Can someone help me solve This. Use photo as context. In exponential growth functions , the base of the exponent must be greater than 1. How would the function change if the base of the exponent were 1? How would the exponent change if the base of the exponent were between 0 and 1?
Answer:
If the exponent was 1, the function would remain constant but if the function was between 0-1 it would decrease towards the x-axis.

· Jessica has 5x - 3 magazines while Kenya has 4x + 2 magazines. How many
magazines do they have altogether?
Answer:
9x-1
Step-by-step explanation:
solution - jessica has 5x-3 magazines
kenya has 4x+1 magazines
so, magazines do they have together = 5x-3+4x+2
= 9x-1
hence, magazines do they have together = 9x-1

A car's value depreciates by 18% in its first year and is now worth £6789.
What was the original price of the car?
Answer:
£8279.27
Step-by-step explanation:
The given relationship is ...
(original price) × (1 - 18%) = £6789
Dividing by the coefficient of the original price, we find it to be ...
original price = £6789/0.82 = £8279.27
The original price of the car was £8279.27.
Find the factorization of the polynomial below. 81X2 - 18x+1
A. (18x-1)2
B. (9x-1)2
C. (9x + 1)2
D. (18x + 1)2
Answer:
B.(9 x -1)^{2}
Step-by-step explanation:
Rewrite the expression into the form of a^2\pm 2ab+b^2:(9 x)^{2} - 2 \times 9 x + 1^{2}
Factor the expression using a^{2}\pm 2ab+b^{2}=(a\pm b)^{2}:(9 x -1)^{2}
we have 81x^2 - 18x+1 = (9x)^2 -2.9x + 1 = (9x -1)^2

2.5x+6=0.5x+46
subtract 0.5x from both sides
2x+6=46
subtract 6 from both sides
2x=40
divide both sides by 2
x=20

A garden swimming pool with a cuboidal shape is 8m long and 4m wide and 150 cm deep. The pool which is partially filled has 40m cube of water in it. What is the height of the water level in the pool
Answer:
the pool with 40m³ of water in it is 1.25m deep
Step-by-step explanation:
first convert 150 cm to 1.5m
2nd 8m l × 4m w × 1.5m d = 48m³
3rd divide 40m³ by 8m l × 4m w or 32m²
40m³/32m² = 1.25m deep

Select the correct answer. The probability that Ashley drives faster than the speed limit (event A) is 0. 34, and the probability that he gets a speeding ticket (event B) is 0. 22. The probability that he drives faster than the speed limit, given that he has gotten a speeding ticket, is 1. Are events A and B dependent or independent? A. Dependent B. Independent C. Insufficient data D. Depends on the other events in the sample space.
Answer:
Depends on other factors, although I'm not certain, so to speak.
Step-by-step explanation:
We don't know the probability of Ashley getting a speeding ticket when he is not speeding. [It happens].
Otherwise, event B is dependent on event A. Speeding must occur to initiate event B.
