Answers

Answer 1

Answer:

caroline types 3500/50=70 words in 1 minute

natasha.............4550/70=65..................................

krutika................2400/40=60...............................

so the answer is A

Step-by-step explanation:

Answer 2

Answer:

A) Caroline

Step-by-step explanation:

To find this, simply divide the amount of words they type by the amount of minutes they type:

To solve Caroline's do:

3500/50=70

Caroline types 70 words per minute.

To solve Natasha's do:

4550/70=65

Natasha types 65 words per minute.

To solve Krutika's do:

2400/40=60

Krutika types 60 words per minute.

Since Caroline has the highest wpm, we can safely say that Caroline types the fastest rate of words per minute.

Mary is buying tickets for a movie.
• Each adult ticket costs $9.
• Each child ticket costs $5.
• Mary spends $110 on tickets.
• Mary buys 14 total tickets.
How many adult tickets, and how many child tickets, does she buy?
Please explain your work! I will mark brainliest if you do :)

Answers

adult ticket = 10

child ticket = 4

Step-by-step explanation:

for example…

adult ticket = xchild ticket = y

so that we get a system of equations

9x + 5y = 110…Equation 1

x + y = 14…Equation 2

solve the system of equations, this time I will use the Elimination and Substitution method

9x + 5y = 110

x + y = 14 (multiplied by 5)

↓↓↓↓↓↓↓

9x + 5y = 110

5x + 5y = 70

___________ _

4x = 40

x = 10

to find value of y subtitute x to one of Equation. for example from second Equation…

x + y = 14

10 + y = 14

y = 14 - 10

y = 4

∴ So, the number of each ticket was she bought is 10 adult ticket and 4 child ticket.

4(6x^2-2x-9x-3)

Then find the common factor for both pairs

4(6x^2-2x-9x-3)

Answers

Answer:  7m³ - 2y²  

Step-by-step explanation:

Answer = (9m³ + 5m² - 3y²) - (2m³+2m²) - (3m² - y²)     [expand the brackets]

            = 9m³ + 5m² - 3y² - 2m³- 2m²-3m² + y²           [group like terms]

            = 9m³- 2m³+ 5m²- 2m²- 3m²- 3y²+ y²             [simplify]

Step-by-step explanation:

The range is all of the y values that make a function true. Our graph here starts at y=-2 and then goes up for infinity. This means the range is y ≥ -2. The domain is [0, ∞) because our x values start at 0 and go to infinity. This means the domain is restricted so A is not true, B is not true because the graph does not exist at x = -2.

7/8 - 4/5 what is the answer to this thing because i don't know it at all duhhhh

Answers

7/8-4/5. When subtracting two fractions, we must have a common denominator. A common denominator is a factor in which goes into both 8 and 5.

1.) Common factor: 45. 45 goes into and 8 and 5. If we list out all the factors of 8 and 5, 45 will be the lowest common factor.

2.) We need to multiply by a number to get 45 for each denominator. We can a one-step equation to figure out what we need to multiply 8 by and 5 by to get 45.
X=the factor of 8 that will get us 45.
8x=45
8x/8=45/8
x=5.625.
Y=factor of 5 that will get us 45.
5y=45
5y/5=45/5
y=9.

3.) We now know that we need to multiply 8 by 5.625 and 5 by 9 in order to get 45 as the denominator for both fractions.
7/8x5.625-4/5x9
7/45-4/45.

4.) Whatever is done to the denominator must be done to the numerator.
7x5.625/45-4x9/45
39.375/45-36/45

5.) We now have common denominators, so we simple subtract the numerators ONLY. We DO NOT subtract the denominators.
39.375/45-36/45=3.375/45.

Therefore, 3.375/45 is your answer.

hello! again... im so confused on this. could someone please help me figure out the answer + explanation? tysm!

Answers

Let’s first start with what is the parent function of a quadratic: f(x) = x^2.

Then, to get to x^2 + 1, the parent function was basically moved up by 1 on a graph.

To go from that equation to the h(x) function just follow the rules. Anything inside of a parentheses followed by a square is the opposite of what it actually is. So if you have (x - 8)^2, you’re moving the parent function 8 units to the right, instead of the left. If it’s (x + 8)^2, you are moving to the left 8. Anything outside of the parentheses that is being subtracted or added is moving the parent function down or up, respectively. Therefore, when it tells you + 5 at the end, that just means, up 5. Then if there is a negative out in front of the entire equation like you see there, it is being reflected over the x - axis. Then, the number being multiplied—in this case 3/4– is either a vertical compression or a vertical stretch. If the number is bigger than 1, it is a vertical stretch. If the number is smaller than one, it is a vertical compression.

All in all:

Vertical compression of 3/4
Vertical translation 4 units up
Reflection across the x - axis
Horizontal translation 8 units right
