Hey, Its the same person. This is Algebra 2. Please Help!

Answers

Answer:

first option

Step-by-step explanation:

Given

f(x) = [tex]\frac{2x^2+5x-12}{x+4}[/tex] ← factorise the numerator

     = [tex]\frac{(x + 4)(2x-3)}{x+4}[/tex] ← cancel (x + 4) on numerator/ denominator

     = 2x - 3

Cancelling (x + 4) creates a discontinuity ( a hole ) at x + 4 = 0, that is

x = - 4

Substitute x = - 4 into the simplified f(x) for y- coordinate

f(- 4) = 2(- 4) - 3 = - 8 - 3 = - 11

The discontinuity occurs at (- 4, - 11 )

To obtain the zero let f(x) = 0, that is

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

There is a zero at ( [tex]\frac{3}{2}[/tex], 0 )

Thus

discontinuity at (- 4, - 11 ), zero at ( [tex]\frac{3}{2}[/tex], 0 )

56 first-graders and 24 other students attended a school assembly. What percentage of the students at the assembly were first-graders?

Answers

Answer:

80%

Step-by-step explanation:

We can write the ratio of first graders to students as 56:24.

We have to find the total amount of students so we add those two up and we get 70

Out of 70, there are 56 first graders, so we can write that as a fraction which will be 56/70

To get this to a percent, we have to get it so the denominator is 100, I can do some weird thing, multiplying a decimal over decimal to get to the answer, but that isn't what you would most likely do

The best thing to do in this scenario is to simplify this equation so it has a denominator of 10, so we do divide by 7 on the bottom, divide by 7 on the top, and we get the more simplified fraction, 8/10. And 8/10 is also equal to 80/100 which makes the percent 80%

a handful of coins has the value of 1 dollar and 79 cents there are 3 times as many dimes as quarters and 5 more pennies than dimes if there are only 3 types of coins how many of each type of coin are there

Answers

Answer:

3 Quarters 9 dimes 14 pennies

Step-by-step explanation:

so dimes are x, quarters are y, and pennies are z. Next we know that x*3 y is what dimes are and 5 more pennies then dimes so z+5. Now we do 3 quarters since thats about 100  but less then 3*3=9 so 190 we have 90+75 cents now then we add 14 the cursed number lol but we add 14 because 9+5 is 14 and there are 5 more pennies then dimes.

How many pages did Juan read if he read 1 3/4 times as many pages as Rosa. Lee read 140 3/4 pages which was 36 1/3 pages more than the number of pages that Rosa read

Answers

Answer:

[tex]182\frac{35}{48}[/tex]

Step-by-step explanation:

To find the number of pages Rosa read subtract 36 1/3 from 140 3/4

140 3/4-36 1/3= 104 5/12

Then multiply 1 3/4 to that to get how many pages Juan read

The answer will be [tex]182\frac{35}{48}[/tex]

Jeff spends half of his paycheck he gives 1/3 of the remaining money to the charity and put the rest in the bank what fraction does he put in the bank

Answers

Jeff put 1/6 into his bank. You first make the fractions into common denominators. The nearest number that works would be 15. 1/3 changes into 5/15, 1/2 becomes 7.5/15.

7.5/15 + 5/15 is 12.5/15. Simplified is 5/6.

6/6 minus 5/6 gives you 1/6, therefore the answer is 1/6. Hope this helps!

The difference between 10 and the product of a number and 9 is -73

For this type of problem, just convert the words to math

The difference means "A-B"

The product means "B*C"

So, put those together.

10 - 9x = -73

Then solve for x.

-9x = -83

x = 83/9

LMNP is a rectangle. Find the value of x and the length of each diagonal.
LN = 7x + 11 and MP = 9x-5
X= ???

Answers

Answer:

Step-by-step explanation:

The diagonals of a rectangle are congruent, thus

MP = LN , substitute values

9x - 9 = 7x + 9 ( subtract 7x from both sides )

2x - 9 = 9 ( add 9 to both sides )

2x = 18 ( divide both sides by 2 )

x = 9

LN = 7x + 9 = (7 × 9) + 9 = 63 + 9 = 72

MP = 9x - 9 = (9 × 9) - 9 = 81 - 9 = 72

HELP SOON MARKING BRAINLIEST

Answers

Answer:

What are the choices and what grade level going to 4th-12th

Step-by-step explanation:

The speed is the distance covered by an object at a particular time. It will take 1 and seven-tenths of the day to reach San Francisco.

What is speed?

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

Speed = Distance Covered / Time taken

Given that the speed during the entire journey is 60 miles per hour and you drive for 8 hours per day. Therefore, the distance that you can cover in a day is,

Distance covered in a day = Speed × Time

                                            = 60 miles per hour × 8 hours per day

                                            = 480 miles per day

Now, by road the distance between Washington, DC, and San Francisco, California is 812.5 miles. Therefore, the number of days it would take to reach San Francisco is,

Number of days

= Total Distance to be Covered / Distance covered in a day

= 812.5 miles / 480 miles per day

= 1.7 days

Hence, it will take 1 and seven-tenths of the day to reach San Francisco.

HI, can someone help me? volume of the square

Answers

Answer - 288

Step-by-step explanation:

i use the formula V=a2 h/3

Hello!

Answer:

The volume of the square pyramid shown is 288 inches cubed.

Step-by-step explanation:

We can solve this by using the formula, V = A(h/3), where V is the volume, and A is the area of the base, and h is the height.

We know that the area of a square is S^2, S being the side length, so to find the area of the base, we do 6 x 6, and that's 36.

Now, plug the numbers into the formula V = A(h/3)

V = 36(24/3)

V = 36(8)

V = 288
