Hey there!
Let's think of both of these functions as two different slope-intercept equations (y=mx+b). Don't let all of the fs and gs confuse you; those are just showing that they are two different functions!
Our function f has an equation of y=x, which is a diagonal line that passes through the origin and goes across each small grid on the graph diagonally.
Our function g has an equation of y=-1/3x+2, which means that it will intersect with the y-axis at two units above the origin and for every three whole steps it goes to the right, it will have gradually gone down one whole step as well.
Attached to my answer is what a graph of it would kind of look like. Sorry if the lines don't look too much like a line it's a bit difficult to draw with a mouse haha!

Answers
We have been given an expression [tex]\left( 4^{-2} \cdot 4^{-3} \right)^{3}[/tex]. We have been given steps how Chris tried to solve the given expression. We are asked to choose the correct option about Chris's work.
Let us simplify our given expression.
Using exponent property, [tex]a^m\cdot a^n=a^{m+n}[/tex], we cab rewrite our given expression as:
[tex]\left( 4^{-2+(-3)} \right)^{3}[/tex]
[tex]\left( 4^{-5} \right)^{3}[/tex]
Now we will use exponent property [tex](a^m)^n=a^{m\cdot n}[/tex]to further simplify our expression.
[tex]\left( 4^{-5} \right)^{3}= 4^{-5\cdot 3}[/tex]
[tex]\left( 4^{-5} \right)^{3}= 4^{-15}[/tex]
Therefore, Chris made mistake in step 2.
What is the arc length of the shaded region to the nearest tenth?
Answers
Answer:
285
Step-by-step explanation:
The total amount of degrees in a circle is 360, we know that the un-shaded portion of the circle is 90 degrees this means that the shaded portion has 270 degrees.
We also know that the area of the circle is [tex]\pi r^{2}[/tex] but we are finding a portion of that, therefore we would need to multiply it by [tex](\frac{270}{360} )[/tex]. The radius is also given which is 11.
Area of the shaded region = [tex](\frac{270}{360}) * \pi 11^{2}[/tex] = 285

A manufacturer claims that its cleaning product is best because over half of the cleaning services surveyed used the product. Which BEST decreases the validity of the claim? A.Only 50 cleaning services were surveyed. B.Cleaning services were selected at random. C.A well-known company conducted the survey. D.Only one cleaning product was asked about in the survey.
Answers
Answer:
D. Only one cleaning product was asked about in the survey.
Any given company can use more than one cleaning product or even use a combination of different cleaning products. The question was not specific enough, since it should have probably asked which cleaning products are used and which ones are used more frequently.
Step-by-step explanation:
the other options are wrong because:
A. Only 50 cleaning services were surveyed. ⇒ This actually would increase the validity of the claim because it satisfies the the condition for a valid confidence interval [np and n(1 - p) are larger than 10]-B. Cleaning services were selected at random. ⇒ This actually would increase the validity of the claim. C. A well-known company conducted the survey. ⇒ This actually would increase the validity of the claim.Solve the equation shown for x.

Step-by-step explanation:
2(x-4)=4x+3x+6=
2x-8=7x+6
Subtract 2x from both sides
-8=5x+6
Subtract 6 from both sides
-14=5x
x=-2.8
Answer:
-14/5
Step-by-step explanation:
when opening the RHS bracket.
we will get 2x-8
further solving,
2x-8= 7x+6
then rearranging,
2x-7x= 6+8
-5x=14

A shipment of fifteen smartphones contains seven with cracked screens. If sold in a random order. What is the probability that exactly five of the first nine sold have cracked screens
Answers
Answer:
29.37% probability that exactly five of the first nine sold have cracked screens
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the smartphones are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
5 with cracked screens, from a set of 7.
9-5 = 4 with good screens, from a set of 15-7 = 8.
So
[tex]D = C_{7,5}*C_{8,4} = \frac{7!}{5!(7-5)!}*\frac{8!}{4!(8-4)!} = 1470[/tex]
Total outcomes:
Nine phones, from a set of 15. So
[tex]T = C_{15,9} = \frac{15!}{9!(15-9)!} = 5005[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1470}{5005} = 0.2937[/tex]
29.37% probability that exactly five of the first nine sold have cracked screens
David&dan share a lottery win of £9900 in the ratio 3:2 David then shares his part between himself,his wife and their son how much more does his wife get over their son
Answers
Answer:
Step-by-step explanation:
The question is incomplete. The complete question is:
David & Dan share a lottery win of £9900 in the ratio 3 : 2. David then shares his part between himself, his wife & their son in the ratio 4 : 4 : 2. How much more does his wife get over their son?
Solution:
David & Dan share a lottery win of £9900 in the ratio 3 : 2. The total ratio is 3 + 2 = 5
The amount that David got would be
3/5 × 9900 = £5940
Therefore, £5940 was shared in the ratio of 4 : 4 : 2. The total ratio is 4 + 4 + 2 = 10
The amount that his wife gets is
4/10 × 5940 = £2376
The amount that his son gets is
2/10 × 5940 = £1188
The amount that his wife gets over their son is
2376 - 1188 = £1188
There are 20 marbles in a jar. There are 6 red marbles, 3 green marbles, and the rest are purple. What is the probability of getting a purple marble if you take a marble out of the bag
Answers
Answer:
55% probability of getting a purple marble if you take a marble out of the bag
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
20 marbles.
6 are red.
3 are green
The rest(x) are purple.
So
6 + 3 + x = 20
x = 11
20 marbles, of which 11 are purple.
11/20 = 0.55
55% probability of getting a purple marble if you take a marble out of the bag

Jacobs pizza parlor sells pizza for $10 each, with a $20 delivery fee. Ashley's pizza parlor has a $12 delivery fee and sells pizza for $12 dollars each. At what point do the pizza parlors cost the same to deliver pizza?
Answers
Answer:
The pizza parlors cost the same when delivering 4 pizzas.
Step-by-step explanation:
For each store, the total price is
cost of pizzas + cost of delivery
The cost of delivery is just a fixed number for each store, $20 or $12.
The cost of the pizzas is the price of a pizza multiplied by the number of pizzas.
Let x = number of pizzas
The cost of the pizzas is
Jacob's: 10x
Ashley's: 12x
Jacob's total cost (pizzas + delivery):
10x + 20
Ashley's total cost (pizzas + delivery):
12x + 12
We want the total costs to be the same, so we set our two total cost expressions equal and solve for x.
12x + 12 = 10x + 20
Subtract 10 from both sides.
2x + 12 = 20
Subtract 12 from both sides.
2x = 8
Divide both sides by 2.
x = 4
Answer: The pizza parlors cost the same when delivering 4 pizzas.

Answers
Answer:
81
Step-by-step explanation:
-9^2, or -9 times -9 equals 81, the negatives cancel each other out
Your answer would be 81.
The calculation the question is asking us to do is y², but substitute in y for -9. This gives us (-9)². We know that 9² = 81, but (-9)² also equals 81 because when you multiply 2 negative numbers together, the negative sign cancels out.
