Answer:
y=1/3 x -6, y equals one third x minus 6
Step-by-step explanation:
The equation will look like -5/3 - -8/-6 since we're finding the slope. That equals 3/9 or 1/3, the slope is 1/3. But since we also need to find the y-intercept, we need to solve another equation, y-y1=m(x-x1). Now we just need to put in the values. y-(-5)=1/3(x-3) this becomes y+5=1/3 x - 1, subtract 5 to isolate y, y=1/3 x -6.

The number of minutes need to complete a set of tasks varies directly with the number of tasks and inversely with the number of people working on the task. if it takes 91 people 2 minutes to complete 13s task, how long, in minutes, will it take two people to complete 4 tasks
Answer:
28 minutes
Step-by-step explanation:
y =kz/x where k is the constant of variation
y = number of minutes and x is people involved and z is the number of tasks
2 = k * 13/91
2 = k * 1/7
Multiply each side by 7
2*7 = k * 1/7 *7
14 =k
y =14 z/x
y = 14 * 4/2
y = 28

Abby is adopting kittens from the pet store. if there are 18 kittens, how many ways can she choose 2 kittens? **the answer isnt 9 or 32**
Answer:
153 ways.
Step-by-step explanation:
The answer is the number of combinations of 2 from 18
= 18! / 2! (18-2)!
= 18! / 2! 16!
= 18*17*16! / 2! 16!
= 18 * 17 / 2*1
= 9 * 17
= 153 ways.

A quadratic equation is an equation whose leading coefficient is of the second degree. The correct option is C.
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
Its roots are given as:
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
The second-degree polynomial function that has roots –3 and 5 are,
f(x) = (x+3)(x-5)
f(x) = x² + 3x - 5x -15
f(x) = x² - 2x - 15
Now, it is needed that the polynomial's leading coefficient should be 2. Therefore, the polynomial should be multiplied by 2. Thus, the polynomial will be,
f(x) = 2x² - 4x - 30

Find the value of x in each case:
Answer:
X = 11
Step-by-step explanation:
To solve this, we need to find all the angles within the triangle. We know one angle (f) is 33 degrees because 147 + f = 180 = f = 33. Next we need to set up two more formulas to solve for x:
4x + y = 180
x + y + 33 = 180 => x + y = 147
Next, we can isolate one of the variables in one of the formulas and plug it back into the other:
x + y = 147 => y = 147 - x
4x + y = 180 => 4x + 147 - x = 180 => 3x + 147 = 180 => 3x = 33 => x = 11
I hope this helps!

The required measure of x in the angles is 11.
Given that,
To determine the value of x in the measure of angles.
The angle can be defined as the one line inclined over another line.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Alternate corresponding angles
∠GFB = ∠FBA
∠FBA = 147°
Alternate corresponding angles
∠DEB = ∠EBC
4x = x + ∠CBF
∠CBF = 3x
Now,
∠CBF + ∠FBA = 180
3x + 147 = 180
3x = 180 - 147
3x = 33
x = 11
Now
∠DEB = 4x = 44°
Thus, the required measure of x in the angles is 11.

A survey of Micki's customers showed that 1,800 out of 2,200 of the customers buying carrots would buy organic carrots if the carrots were placed near the front of the store. In the first month, 1,500 of those 2,200 customers actually bought the organic carrots. What was the percent error in the survey estimate of the number of people buying organic carrots?
Answer:
13.63%
Step-by-step explanation:
The computation of the percent error is shown below;
= (Showing amount - first month amount) ÷ (Actual purchased)
= (1,800 - 1,500) ÷ (2,200)
= (300) ÷ (2,200)
= 13.63%
Hence, the percent error is 13.63%
We simply applied the above formula so that the correct percent error could come and the same is to be applied
Answer:
83.3%
