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!
PLEASE HELP!!!!!!!! THANKS!!!!!!!!!

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.

6 avacodos is 10$. How much is it for 12
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:
[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]
What is the product? (-3s+2t)(4s-t)
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)
You have one type of chocolate that sells for $6.00/lb and another type of chocolate that sells for $9.70/lb. You would like to have 11.1 lbs of a chocolate mixture that sells for $7.50/lb. How much of each chocolate will you need to obtain the desired mixture? You will need ______ lbs of the cheaper chocolate and ______ lbs of the expensive chocolate.
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

4 7 + 4 6
Explanation:
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

Using π = 3.14, find the area of a circle with a radius of 5.6. Round your answer to the nearest hundredth.
Answer:
98.47
Step-by-step explanation:
A = πr²
A = (3.14)(5.6)²
According to PEMDAS exponents come before multiplication. 5.6² is 31.36
The next step is to multiply this answer by pi (3.14)
3.14*31.36 = 98.47

In the Pythagorean Theorem, what
does the "a" stand for?
a2 + b2 = c2
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.

can someone help me again? asap
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).
