How is the graph if y=2x^2 -9 different from the graph of y=2x^2+8

Answer:

a = 51 , b = - 7

Step-by-step explanation:

Expand and simplify left side , then compare like terms on both sides.

4(9x + 11) + 5(3x + b) ← distribute parenthesis

= 36x + 44 + 15x + 5b ← collect like terms

= 51x + 5b + 44

Compare terms with right side ax + 9

Compare x - terms

51x and ax

For these terms to be equal then

a = 51

Compare constant terms

5b + 44 and 9

For these terms to be equal , then

5b + 44 = 9 ( subtract 44 from both sides )

5b = - 35 ( divide both sides by 5 )

b = - 7

Answer:y=2/5x+5

Step-by-step explanation:

Answer:

y=x/4

Step-by-step explanation:

slope =y2-y1/x2-x1

=1-0/4-0=1/4

Answer: slope intecept form: y = 1/4x

Step-by-step explanation: first we need to find the slope:

Since we have the coordinates (0,0) and (4,1), we can find the slope, which we find 1/4. We can double check this by seeing if the next point is found +4 to the right and up 1.

We have y = 1/4x + b right now, so we need to find the y intercept, in which case is zero because it goes through the origin.

So your final answer is y = 1/4x + 0, or y = 1/4x for short.

Answer: y-int = 2

Step-by-step explanation:

set x=0

so 18(0) + 5y = 10

solve for y by dividing both sides by 5

5y/5 = 10/5

y=2

Answer:

The function to represent the revenue received  by the club is

Step-by-step explanation:

Given:

Total members in the Online shopping Club = 13,500

Membership Charge per month =  $8

Increase in the Membership  charge per month = $1

For each $1 monthly increase in membership fee, the club loses approximately  = 500 members

To Find :

The function to represent the revenue received  by the club when x is the price increase

Solution:

For Each month $1 increased is every month which leads to decrease in the members by 500

For 1 month , one dollar  the decrease  is  

for 2 month , 2 dollar increase will lead to decrease of  = 1000  members

So for x months

The decrease in the members  = = 500x

Also the increase in the membership fee will be 8 + x

Answer:

B

Step-by-step explanation:

Answer:

B) There were N people on the beach at 10:00a.m.

Step-by-step explanation:

As stated, "t" represents the hours past midnight. So the first part states that it is 10 hours after midnight. Since we know its ten hours after midnight, aka 10am, what we don't know is how many people are on the beach. therefore we know the answer is B.

Answer:

1. 4.5 x 10^5

2. Reflection

3. 10^16

4. t = 4

5. 230

6. 0

7.  1/2x^2

Step-by-step explanation:

1. There are 4 zereos in the number, and in order to convert something to scientific notation, there has to be a decimal that is less than 10, so you would convert the 45 to 4.5. The number of places to move over from the decimal in 4.5 to the end of the number 450,000 is 5, so it would be 10 to the 5th power (10^5).

2. A reflection is when a shape is flipped across an invisible line. Imagine a vertical line. If you took the triangle on the left and flipped it over the line, you would get the triangle on the right, so it's a reflection.

3. When multiplying two powers of 10 like this, you just add the exponents. So your answer would be 10^(7+9) = 10^16.

4. Start by multiplying both sides by 5.

t + 16 = 20

Then subtract 16 from both sides. And you get...

t = 4

5. 4.4 + 0.2 = 4.6 so then divide that number by 0.02. Remember, when dividing a number by another number that is less than one, the answer will be bigger than the original number. 4.6 / 0.02 = 230

6. Exponents represent the number of times you multiply the original number. So 5^1 is just 5 since you don't multiply it by 5 again. 3^2 = 3 * 3 = 9. 4^0 is 1 because all numbers to the 0th power are 1. Take all of these numbers and add/subtract accordingly. Remember PEMDAS, so the 5*3 is multiplied before it is subtracted.

5 + 9 + 1 = 15

15 - (5*3) = 0

7. The two x^3 on the bottom can be added together to create 2x^3. Then you can cancel out x^2 from both the top and bottom.

x^2/(2x^3) = 1/2x^2

Hello studentUnion!

[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]

Solve the equation-

[tex] \frac{5}{x - 3} - \frac{4}{x + 4} = \frac{1}{x} \\ [/tex]

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex] \frac{5}{x - 3} - \frac{4}{x + 4} = \frac{1}{x} \\ [/tex]

Let's multiply both the sides of the equation by x (x - 3) & (x + 4) which is the LCM of (x - 3), (x + 4) & x. We can't solve it directly without taking the LCM first as the denominators are not equal to each other. Then do cross multiplication. After all these steps, you'll get an equation as..

[tex]x\left(x+4\right)\times 5-x\left(x-3\right)\times 4=\left(x-3\right)\left(x+4\right) \\ [/tex]

Now, use the distributive property & simplify it.

[tex]x\left(x+4\right)\times 5-x\left(x-3\right)\times 4=\left(x-3\right)\left(x+4\right) \\ \left(x^{2}+4x\right)\times 5-x\left(x-3\right)\times 4=\left(x-3\right)\left(x+4\right) \\ 5x^{2}+20x-x\left(x-3\right)\times 4=\left(x-3\right)\left(x+4\right) \\ 5x^{2}+20x-\left(x^{2}-3x\right)\times 4=\left(x-3\right)\left(x+4\right) \\ 5x^{2}+20x-\left(4x^{2}-12x\right)=\left(x-3\right)\left(x+4\right) \\ 5x^{2}+20x-4x^{2}+12x=\left(x-3\right)\left(x+4\right) \\ x^{2}+20x+12x=\left(x-3\right)\left(x+4\right) \\ x^{2}+32x=\left(x-3\right)\left(x+4\right) \\ x^{2}+32x=x^{2}+x-12 \\ x^{2}+32x-x^{2}=x-12 \\ 32x=x-12 \\ 32x-x=-12 \\ 31x=-12 \\ \boxed{ \boxed{ \bf \: x=-\frac{12}{31} }}[/tex]

Use Cross multiplication

Answer:

whats the question

Step-by-step explanation:

Answer:

When a line is parallel to another line, they have the same slope. So far the equation would be, y=4x+b. To find the value of b, substitute the given point into the equation.

8=4(-1)+b

8=-4+b

b=12

So, the equation of the line is y=4x+12.

y=4x-2

Answer:

45o

Step-by-step explanation:

Angles 1 and 2 form a linear pair and are supplementary. So to find m∠2, subtract m∠1 from 180o. m∠2 = 180o - 135o = 45o.

Answer: 90

Step-by-step explanation:

You can write "the measure of angle 1" as m ∠1. ∠1 and ∠2 are complementary, and m ∠2 = 32. Find m ∠ 1. m ∠1 + 32 = 90 Substitute 32 for m ∠2.
