HELP ASAP! What are the slope and y-intercept of the linear function that is represented by the table?
A. The slope ls -2, and the y-intercept is 6.
B. The slope ls -2, and the y-intercept is 12.
C. The slope is 2, and the y-intercept is 6.
D. The slope is 2, and the y-intercept is 12.
Answers
Answer:
A
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use two points and find slope initially so,
(-3,18) (0,12)
18-12=6 , -3-0= -3
so the slope is 6/-3 = -2 so by this answer is either a or b .
further apply y =mx + c as it linear to find c
y= -2x + c
0 = -2x6 + c
c = 12
so slope is -2 , c is 12

What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
You have a budget of $1,900 per week for employees.
Employees are paid $11 per hour and work 40 hours per week.
That means,
11 x 40 = $440 per week.
The number of employees = 1900/440

What is the equation for
7x - 4/y =10
in the form y = mx + b?
Answers
Answer:
Step-by-step explanation:
assume the equation is (7x-4)/y=10
10y= 7x-4 didvide both sides by 10
y= (7/10)*x - (2/5)
m=7/10
b=-2/5
The equation for 7x - 4/y =10 in the form y = mx + b . The equation in the form
[tex]\(y = mx + b\) is: \[y = \frac{4}{7x - 10}\][/tex]
To rewrite the equation in the form we need to [tex]\(y = mx + b\),[/tex] isolate the term involving y on one side of the equation. Here's the step-by-step process:
Step 1: Add [tex]\(\frac{4}{y}\)[/tex] to both sides of the equation to isolate the 7x term on the left side:
[tex]\[7x = 10 + \frac{4}{y}\][/tex]
Step 2: Get rid of the fraction by multiplying both sides of the equation by y:
[tex]\[7xy = 10y + 4\][/tex]
Step 3: Now, we want to express y alone on one side. To do this, subtract 10y from both sides:
[tex]\[7xy = 10y + 4\][/tex]
Step 4: Factor out y on the left side:
[tex]\[y(7x - 10) = 4\][/tex]
Step 5: Finally, divide both sides by to solve for [tex]\((7x - 10)\)[/tex]
[tex]\[y = \frac{4}{7x - 10}\][/tex]
Now, the equation is in the form where [tex]\(y = mx + b\), \(m\)[/tex] is the coefficient of x and b is the constant term. In this case,[tex]\(m = \frac{4}{7x - 10}\) and \(b\)[/tex] is equal to 0.

Mixed Fractions
Mixed fractions are made of an integer part followed by a proper fraction.
Some examples of mixed fractions are:
3 1/2, -4 5/8, 2 2/3
Between two consecutive integers a and a+1, there are infinitely many fractions. The centered number is a 1/2. Any number with its improper fraction part less than 1/2 is closer to a than to a+1.
In our problem, Jayne bought between 2 and 3 pounds of granola. We need to provide a mixed number that is closer to 2 pounds than to 3 pounds.
We can select any number with integer part 2 and a proper fraction less than 1/2.
Examples could be :
2 1/3, 2 1/4, 2 3/7
All of them are less than 2.5
A storage company designs a rectangular box with an open top that has a volume of 220 in3. Each box has a length that is three times its width. Calculate the minimum surface area of one of these boxes. Round your answer to three decimal places.
Answers
Answer:
191.016 in²
Step-by-step explanation:
Let the volume of the cube be V = lwh where l = length of box, w = width of box and h = height of box.
Now l = 3w.
So, V = lwh = (3w)wh = 3w²h
h = V/3w²
Since the rectangular box is open at the top, its total surface area is A = lw + 2lh + 2wh
substituting l = 3w, we have
= (3w)w + 2h(l + w)
= 3w + 2h(3w + w)
= 3w² + 2h(4w)
= 3w² + 8wh
substituting h = V/3w²
= 3w² + 8w(V/3w²)
A = 3w² + 8V/3w
Differentiating A with respect to w and equating it to zero, we have
dA/dw = d[3w² + 8V/3w]dw
dA/dw = d3w²/dw + d(8V/3w)/dw
dA/dw = 6w - 8V/3w²
dA/dw = 0
6w - 8V/3w² = 0
6w = 8V/3w²
6w³ = 8V/3
w³ = 8V/(3 × 6)
w³ = 4V/9
w = ∛(4V/9)
substituting V = 220 in³, we find the minimum value for the width
w = ∛(4 × 220 in³/9)
w = ∛97.7778
w = 4.607 in
To determine if this is a minimum value of width which gives minimum area, we take the second derivative of A. So,
d²A/dw² = d(6w - 8V/3w²)/dw
= 6 + 16V/3w³
substituting w³ = 4V/9, we have
d²A/dw² = 6 + 16V/3(4V/9)
= 6 + (16 × 9)/(3 × 4)
= 6 + 4 × 3
= 6 + 12
= 18
Since d²A/dw² = 18 > 0 , w = ∛(4V/9) = 4.607 in gives a minimum for the surface area.
So, we calculate this area by substituting w = 4.608 in. So,
A = 3w² + 8V/3w
= 3 × (4.607 in)² + (8 × 220 in³)/(3 × 4.607 in)
= 63.6733 in² + 1,760 in³/13.821 in
= 63.6733 in² + 127.3424 in²
= 191.0157 in²
≅ 191.016 in² to three decimal places.

Number of boys = 30
The president must be a girl and the vice president a boy
To find:
Number of ways to choose a president, vice president, and secretary.
Solution:
The president must be a girl and the vice president a boy. So, out of three students 1 is girl and 1 is boy. Third student can be a girl or a boy.
Total number of ways = Selecting 2 boys and 1 girl + Selecting 1 boy and 2 girls

Answers
Answer:
no
Step-by-step explanation:
Answer:
Yes, if you are referring to proportionality in general. No if you are referring to a direct proportionality.
Step-by-step explanation:
y = -2x is negatively proportional so it is not directly proportional because y or one quantity decreases when x or another quantity increases. In a directly proportional relationship, as one quantity increases another quantity must increase at the same rate, in other words both must increase thus be positive. When something is proportional it has a constant ratio, and relation.
Direct proportionality or variation is represented by y ∝ x, where ∝ is the symbol used to represent proportionality.
y = kx where k is the constant of proportionality.
Where k = y/x.
