i really don't understand this yall

Answer:

C) y=x^2+x-6

Step-by-step explanation:

Looking at the first picture, the equation is way too high, thus A is incorrect

Looking at the second picture, the equation is also too high, thus B is incorrect

Looking at the third picture, the equation is at the graph, thus C is correct

Looking at the fourth picture, the equation is more at the right than at the left thus the equation is incorrect

Hope this helps!

Answer:

a. = x > 3

b. = x < 2

c. = x > -5

d. = x > 10

Step-by-step explanation:

Solve means to find x.

a.

3x - 3 > 6

+3 each side

3x > 9

Divide by 3 each side

x > 3

b.

24x + 4 < 52

-4 each side

24x < 48

Divide by 24 each side

x < 2

c.

-2x - 2 < 8

+2 each side

-2x < 10

Divide by -2 each side (Causing the inequality sign to flip, dividing or multiplying by a  negative causes it to.)

x > -5

d.

10x - 100 > 0

+100 each side

10x > 100

Divide by 10 each side

x > 10

Answer:

a = 28.14 (Estimated)

Step-by-step explanation:

7a + 50 = 247

=> 7a = 197

=> a = 28.1428571429 (Using Calculator)

=> a = 28.14 (Estimated)

Hoped this helped.

Answer:

a= 190

Step-by-step explanation:

7a+50=247

=7a = 247-50

= a = 197-7

= a = 190

Answer:

C. y=3x+5

Step-by-step explanation:

It is at a growing rate of 3cm a month.

x = centimeters a month

y = total amount

She can read 70 pages in 3 hours.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We are Given:

Giovanni can read 210 words per minute and, books contain 540 pages

So, she can read the portion of book

=210/540

= 21/54 per minutes

= 21/54  x 60

= 23.3 pages in one hour

and in 3 hours she can read

= 23.3 x 3

= 70 pages in 3 hours

Answer:

4 feet I think

Step-by-step explanation:

We want to find the total number of people that Annette surveyed given that we know a percentage and the number that the percentage represents.

We will find that the number of people that Annette survey is 480.

To get the solution:

Let's assume that she surveyed a total of X people.

Then we can write the equivalence:

100% = X

We know that the 37.5% is equivalent to 180 people, then we can write:

37.5% = 180

The two equations are:

100% = X

37.5% = 180

Now we can take the quotient between these two equations to get:

(100%/37.5%) = X/180

Solving for X we get:

(100%/37.5%)*180 = X = 480

So the total number of people surveyed is 480.

Answer:

480 people

180/X × 100 = 37.5%

180 × 100 = 37.5 × X

18000 ÷ 37.5 = 37.5 × x ÷ 37.5

480 people = x

Answer:

12/5

Step-by-step explanation:

His fish tank is 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. So you need to find out how many gallons you can pour in 1 minute. You can eliminate A (5/12) because he is filling more than 1 gallon per minute. You can divide   4.5 (4 1/2) by 1.875 (1 7/8). You get 2.4. Convert it back to a fraction, and you get 2 4/10. Simplify the fraction 2/5. Now convert it to an improper fraction. 12/5.

SORRY IF IT'S WRONG

Answer:

x = 10

Step-by-step explanation:

if there 2 same triangle then they are right triangle

By using Pythagorean theorem for 1 of right triangle, we have

[tex]\sqrt{74} ^{2}[/tex] = [tex]7^{2}[/tex] + [tex](\frac{x}{2}) ^{2}[/tex]

74 = 49 + [tex]\frac{x^{2}}{4}[/tex]

74 - 49 = [tex]\frac{x^{2}}{4}[/tex]

25 = [tex]\frac{x^{2}}{4}[/tex]

therefore, x = [tex]\sqrt{25*4}[/tex] = [tex]\sqrt{100}[/tex] = 10

Answer:

Green is with C, Blue is with A, Orange is with D, Purple is with B

Step-by-step explanation:

Hi!

So, it's been a while since I've done math like this, so the way I solved this was simply by doing the equations themselves and seeing which one matches. I'm sure there is an algebraic way to find which ones match, but this is all I know how to do :)

(By the way...I got the decimals by doing the fraction itself. 1 divided by 4(1/4th)=.25, as an example)

1(left)-7/1/4 is the same as 7/ .25. This is 28.

2(left) 2/3/ 4/5 is the same as .6666666/ .8. This is .83333repeating

3(left) 4/5 / 3/2 is the same as .8/1.5. This is .53333repeating

4(left) 1/4 / 1/7 is the same as .25/.143. This is 1.74(approx.)

1(right) 2/3 x 5/4 is the same as .66666 x 1.25 This is .8333 approx.

2(right) 1/4 x 7 is the same as .25*7. This is 1.75

3(right) 7*4 is 28.

4(right) 4/5 x 2/3 is the same as .8x.66666. This is .533

Now, we can match.

Green is with C.

Blue is with A

Orange is with D

Purple is with B

Hope I could help!

Answer:

40 nickels

Step-by-step explanation:

1 2/5 to 2 1/3 = 7/5 : 7/3

                      = 21/15 : 35/15

21/15 = 24

35/15 = x

(35/15 * 24) / 21/15

∴ 56 ÷ 21/15

= 40 nickels

Answer:

Exponential decay.  Your growth factor is 1/8, which is between 0 and 1.  Thus, the value is decreasing exponentially.

If the growth factor is greater than 1, you have exponential growth.  Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.
