I WILL LITERALLY GIVE OUT 50 POINTS FOR THIS!!!!

Answer:

Step-by-step explanation:

y = ax + b

we will obtain a and b values, based in f(6)=8 and f(9)=3

f(6)=8 ⇒ 8 = a 6 + b ⇒ b = 8 - 6a

f(9)=3 ⇒ 3 = a 3 + b (sustituing b by above expression) ⇒ 3 = 3a + 8 - 6a

⇒ 3 = -3a + 8 ⇒ a = 5/3

b = 8 - 6 . 5/3 ⇒ b = 8 - 10 ⇒ b = -2

so, the linear function is:

f(x) = 5/3 x - 2

---- I'm sorry, f(9)=3 does not match /// there must be an error somewhere in my calculations /// hope can help. cheers!

Answer:

D) There were 176,400 samples of the orchestra music taken every second

Step-by-step explanation:

Just did the test

Answer:

A theorem stating that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other sides. It is mathematically stated as c2 = a2 + b2, where c is the length of the hypotenuse and a and b the lengths of the other two sides.

Step-by-step explanation:

Answer:

a stands for one of the sides opposite the hypotenuse

Step-by-step explanation:

The Pythagoras theorem is

c^2 = a^2 + b^2

which states that the square of the hypotenuse is equal to the sum of the squares of the two opposite sides.

Answer:

−12s2+11st−2t2

Step-by-step explanation:

Hope this helps!

Answer:

-12s - 2t

Step-by-step explanation:

First simplify the like terms.

-3s * 4s = -12s

(-12s + 2t)(-t)

Simplify the like terms again.

2t * (-t) = -2t

-12s - 2t.

Or

12s + 2t. (You can get this by multiplying the equation by -1)

Answer:

3.) Choice B

4.) Choice A

Step-by-step explanation:

Question #3:

You can find the equation by doing the y divided by the x and you'll get 4 every time so that's why it's Choice B.

Question #4:

A proportional equation is always a straight line that goes through the origin. So the answer is Choice A because it's the only one without a y-intercept because if the equation had a y-intercept it wouldn't go through the origin. For example, Choice B would go through (0,5) and Choice C would go through (0,-1) but we need it to go through (0,0).

The correct length of the court is 1126.8 inches.

You can find this value by taking 31.3 yards times 36 to equal 1126.8 inches.

Answer:

Step-by-step explanation:

divide 10 dollars by 6 avacados to get your unit rate, and then multiply that by 12 to get your cost.

10/6 is 3/2

3/2 times 6 is 18

so 18 dollars for 12 avacados

Answer: $20 if six avocados are $10 add 10+ 10= 20

Answer:

10a+6b

pls mark as brainliest.

Step-by-step explanation:

I think you mean 4a+6(a+b)?

We need to multiply out the the 6(a+b) first.

4a+6(a+b)

=> 4a+6a+6b

Then, we can add the like terms, which in this case are 4a and 6a:

=> 10a+6b

got it right on the test

Answer:

Step 2 : The error started at this step, when the student took 2x and 3x [Instead of 3x and 3x]. This is because 3x and 3x multiply to 9x^2 and sum up to 6x;whereas 2x and 3x multiply to 6x^2 and sum up to 5x.

Answer:

28) slope -3 y intercept -13

29) slope -4 y intercept 37

30) slope 4 y intercept -6

Answer:

[tex]\frac{3}{1}[/tex] or 3

Step-by-step explanation:

To find the slope find two coordinates and set up the equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0. [tex]\frac{8_{}-2_ }{2-0_ }[/tex] you have to do subtraction first. 8-2 = 6 and 2-0 = 2

Now we have the equation [tex]\frac{6}{2}[/tex]

this can be simplified to  [tex]\frac{3}{1}[/tex]

Answer:

lbs of the cheaper chocolate => x = 6.6 pounds(Ibs)

lbs of the expensive chocolate => y = 4.5 pounds(Ibs)

Step-by-step explanation:

Let's the :

lbs of the cheaper chocolate => x

lbs of the expensive chocolate => y

You would like to have 11.1 lbs

Hence:

x + y => 11.1

x = 11.1 - y

You have one type of chocolate that sells for $6.00/lb and another type of chocolate that sells for $9.70/lb. of a chocolate mixture that sells for $7.50/lb.

Hence:

$6.00 × x + $9.70 × y = $7.50 × 11.1

6x + 9.7y = 83.25

Hence, we substitute 11.1 - y for x

6(11.1 - y) + 9.7y = 83.25

66.6 -6y + 9.7y = 83.25

-6y + 9.7y = 83.25 - 66.6

= 3.7y => 16.65

y = 16.65/3.7

y = 4.5 pounds

x = 11.1 - y

x = 11.1 - 4.5

x = 6.6 pounds

Hence:

You will need 4.5 lbs of the cheaper chocolate and 6.6 lbs of
