because the other options are the same as 10^ -3/5

Answer:

It would be  10^-3

Step-by-step explanation:

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:

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.

Answer:

Than it's a good measure must be a good thing

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

Now

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.

Hope this helps!

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:

C 10 in

Step-by-step explanation:

side of P is [tex]\sqrt{36}[/tex] = 6

side of Q is [tex]\sqrt{64}[/tex] = 8

for missing side use Pythagorean theorem

[tex]r^{2}[/tex] = [tex]6^{2} + 8^{2}[/tex]

r^{2} = 36 + 64

r^{2} = 100

r = 10 in

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:

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.
