Step-by-step explanation:
since c/4 = 139 is the equation, c/4 is a fraction. To get rid of the denominator you have to multiply the denominator in both sides.
If it was x/2 = 4. then multiply 2 on both sides to get 8.

Critique the the reasoning of others. Connor determines the slope between (-2,4) and (3,-3) by calculating 4 -(-3)/ -2 - 3. April determines the slope by calculating 3 - (-2) / -3 - 4. Explain whose reasoning is correct.
Answer:
Connor's
Step-by-step explanation:
According to the slope formula, it is (y2 - y1)/(x2 - x1)
Connor uses the y-values first and put them on the numerator, and that is what you are meant to do, unlike, April. She puts the x-values on top and the y-values on the bottom.

the pdf attached has the answers to all the questions on you assignment
Answer:
f(4) = 7x
Step-by-step explanation:
As we are to be writing the function in function notation this simply means in terms of f(x).
With the value of having 4 hours, you would input this number in terms of f(x).
This would then give you the solution of:
f(4) = 7x because he is working for 4 hours and is paid 7 dollars an hour.

What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change.
Then the cost of the ticket will be
Cost = ($50 - $23) / 2
Cost = $27
If Tristan used a coupon for 25% off. Then the original price for all tickets will be
Original cost = $27 / 0.75
Original cost = $36
Then the cost of each ticket will be
Cost of each ticket = $36 / 2
Cost of each ticket = $18

Suppose that you decide to buy a car for $57,000, including taxes and license fees. You saved $10,000 for a down payment. The dealer is offering you a choice between two incentives. Incentive A is $5000 off the price of the car, followed by a four-year loan at 6.06%. Incentive B does not have a cash rebate, but provides free financing (no interest) over four years. What is the difference in monthly payments between the two offers? Which incentive is the better deal? Use PMT= P r n 1−1+ r n−nt. The difference in monthly payments between the two offers is $nothing. (Round to the nearest cent as needed.)
Answer:
Following are the solution to this question:
Step-by-step explanation:
For incentive A
The car value = 57000
Calculating debt[tex]= 57000 - 10000[/tex]
[tex]= 47000[/tex]
Calculating the debt value after incentive [tex]= 47000 - 5000[/tex]
[tex]= 42000[/tex]
[tex]PMT = \frac{P(\frac{r}{n})}{(1 - (1 + (\frac{r}{n}))^(-nt))}[/tex]
[tex]= \frac{42000 \times (\frac{6.06 \%}{12})}{(1-(1+(\frac{6.06 \%}{12}))^{(-12 \times 4)})}[/tex]
[tex]= \frac{42000 \times (0.00505)}{(1-(1+(0.00505))^{(-48)})}\\\\= \frac{212.1}{(1-(1+(0.00505))^{(-48)})}\\\\=\frac{212.1}{-1.74}\\\\= - 121.89 \ \ or \ \ 121.89[/tex]
For incentive B
The car value = 57000
Calculating the debt value [tex]= 57000 - 10000[/tex]
[tex]= 47000[/tex]
Calculating the monthly payment =[tex]\frac{47000}{(12*4)}[/tex]
[tex]= \frac{47000}{(48)}\\\\= \frac{47000}{(48)}\\\\=979.166[/tex]
difference:
[tex]=121.89 - 979.166\\\\ = - 854.276[/tex]

Answer:
Step-by-step explanation:
"A rectangular room measures 3.8 meters in length and 4.9 meters in width. Jana multiplies both numbers together. Which expression would be best for her to use to check the reasonableness of her decimal multiplication?"
given that
the length is 3.8m long and,
width is 4.9m wide
The expression for the area is
Area= length * width
Area= 3.8*4.9
Area= 18.62 m^2
Therefore the expression best for her to use to check the reasonableness of her decimal multiplication is the area which is 18.62 m^2

A line passes through the point (8,-1) and has a slope of -3/2
Answer:
y = -3/2 x +11Step-by-step explanation:
[tex](8,-1) = (x_1,y_1)\\\\m = -\frac{3}{2}[/tex]
Substitute values into point-slope form
[tex]y-y_1=m(x-x_1)\\\\y -(-1)=-\frac{3}{2} (x -8)\\\\y+1 = -\frac{3}{2}x+12\\\\y = -\frac{3}{2}x +12-1\\\\y =-\frac{3}{2}x +11[/tex]
The equation of line passes through the point (8, -1) will be;
⇒ y = - 3/2x + 11
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (8, - 1).
And, The slope of the line is,
⇒ m = - 3/2
Now,
Since, The equation of line passes through the point (8, -1).
And, Slope of the line is,
⇒ m = - 3/2
Thus, The equation of line with slope - 3/2 is,
⇒ y - (-1) = - 3/2 (x - 8)
⇒ y + 1 = - 3/2 (x - 8)
⇒ y + 1 = - 3/2x + 12
⇒ y = - 3/2x + 12 - 1
⇒ y = - 3/2x + 11
Therefore, The equation of line passes through the point (8, -1) with slope - 3/2 is,
⇒ y = - 3/2x + 11

4x+2=4 if x satisfies the equation above, what is the value of 2x+1
Answer:
2
Step-by-step explanation:
4x + 2 =4 => 4x = 2 => x = 0,5
if x =0,5 => 2x + 1 = 0,5.2 + 1 = 2
The values of "2x+1" will be "2".
The expression,
→ [tex]4x+2=4[/tex]
By subtracting "2" from both sides, we get
→ [tex]4x+2-2=4-2[/tex]
→ [tex]4x=2[/tex]
→ [tex]x = \frac{2}{4}[/tex]
→ [tex]x = 0.5[/tex]
By putting the value of "x" in the expression "2x+1", we get
→ [tex]2x+1 = 2(0.5)+1[/tex]
→ [tex]= 1+1[/tex]
→ [tex]= 2[/tex]

Step-by-step explanation:
Ok, so in a standard equation, there can’t be any fractions, so you would have to multiply everything by 3, making the equation 3y+3=2(x-8) (p.s. don’t multiply the parentheses, leave the numbers in them alone for now). Then, you would go through with the equation process: 3y+3=2x-16. You move the 3 over to the right to make 3y=2x-19. Move the x to the left, -2x+3y=-19. But, there is a problem. The first term of this equation can’t be negative(yes, in standard form, x has to come first). So, you have to multiply everything by -1, resulting in the answer 2x-3y=19. I hope this helps!(The format for a standard form equation is: Ax+By=C).
