What is 2x + 3y + 5 = 0 in the form of y = mx + c? please kindly explain in detail.
Answer:
3y = -2x - 5
Step-by-step explanation:
y = mx + c-----(i)
2x + 3y + 5 = 0
collect like terms to match that of (i) following where x and y are
3y + 5 = -2x
3y = -2x - 5
y = mx + c

what does 118=k+70 answer?
[tex]118 = k + 70 \\ 118 - 70 = k \\ 48 = k[/tex]
Answer: 48
Step-by-step explanation:
You do opposite operations, so instead of adding 70, you subtract subtract it- 118-70=k+70-70. You do it to both sides to keep the equation balanced. Simplify to get 48=k.
Your friend wants to sell painted rocks. He spends $10.00 on startup costs, and each painted rock costs him $0.75 to make. A store offers to pay your friend's startup costs and buy his painted rocks for $0.75 each. How many painted rocks does your friend need to sell to make a profit?
1 rock
10 rocks
14 rocks
Your friend will never make a profit.
Answer:
10 rocks
Step-by-step explanation:
The cost on startup is $10 and each painted rock cost around $0.75 to make. A store pays startup cost and buy painted rocks for $0.75 each there no profit because the cost price and selling price is the same.
Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyramid. Each side of the base of the pyramid is 9 cm and the height of the pyramid is 10 cm. To get the wax for the candle, Devin melts cubes of wax that are each 4cm by 4 cm by 4 cm. How many of the wax cubes will Devin need in order to make the candle? Show Your Work. ( Will Mark Brainliest if answered correctly and Honestly).
Answer:
5
Step-by-step explanation:
Pyramid
[tex]\textsf{volume of a square based pyramid} =\frac{1}{3} a^2h[/tex]
(where [tex]a[/tex] = base edge, and [tex]h[/tex] = height)
Given:
base edge = 9 cmheight = 10cm[tex]\implies \textsf{volume} =\frac{1}{3} \times 9^2\times10=270 \ \mathsf{cm^3}[/tex]
Wax cubes
volume of a cube = w³, where w is the length of one edge
⇒ volume = 4³ = 4 x 4 x 4 = 64 cm³
Solution
To calculate how many wax cubes are needed, divide the volume of the pyramid by the volume of a wax cube:
⇒ 270 ÷ 64 = 4.21875
⇒ 5 wax cubes are needed to make the candle
We need to round this up to 5, since we need to know the number of whole wax cubes. (If we rounded down to 4, there would not be quite enough to fill the pyramid as 4 x 64 = 256 < 270)
What is 2 5/12 divided by 3/4
Answer:
2 20/36.Step-by-step explanation:
Given equation:
2 5/12 ÷ 3/4Solve:
2 5/12 ÷ 3/4= 2 5/12 * 4/3= 2 5*4/12*3= 2 20/36.A book publisher publishes both fiction and nonfiction books. Let F represent the number of words, per chapter, for fiction books, and let N represent the number of words, per chapter, for nonfiction books. The standard deviation of the total amount, S = F + N, is 195.3 words. What is the interpretation of this value?
The mean number of words per chapter will vary from book to book.
On average, there are 195.3 words total in a typical chapter of either genre of book.
This publisher can expect the total number of words per chapter to vary by approximately 195.3 words from the mean.
If we combine the fiction and nonfiction books from this publisher, the average number of words per chapter will change by 195.3.

The elevator of a hotel has a maxirnurn weight capacity of 2,000 pounds. If there are 3 people on the elevator that have a combined weight of 460 pounds, write AND SOLVE an inequality expressing the possible weights that may be added to the elevator, Use "W" to represent weight.
Answer:
W=460+460+460
W=1380
2000≠1380
2000-1380=620
2000=1380+620

bonds be worth at the end of 4 years?
O $4,734.40
O $2,387.25
O $2,411.20
O $211.20
Answer:
$2,411.20
Step-by-step explanation:
Use the simple interest formula: A = P(1 + rt)
A = Final amount (?)
P = Starting amount (2200)
r = Rate (0.024)
t = Time in years (4)
A = 2200(1 + 0.024 · 4)
A = 2200(1.096)
A = 2411.2

Find the distance between the points (6, 4) and (10, 7).
Answer:
5 units
Step-by-step explanation:
Use the distance formula [tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2[/tex] where [tex]d[/tex] is the distance between points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].
Given that [tex](x_1,y_1)\rightarrow(6,4)[/tex] and [tex](x_2,y_2)\rightarrow(10,7)[/tex], then:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(7-4)^2+(10-6)^2}\\\\d=\sqrt{3^2+4^2}\\\\d=\sqrt{9+16}\\\\d=\sqrt{25}\\\\d=5[/tex]
This means that the distance between (6,4) and (10,7) is 5 units

Answer: 2295 ft ^2, 255 yd^2
Step-by-step explanation:
The area of the field is the length times the width.
Since there are 3 feet in 1 yard, 15 yards = 45 feet.
So the area in square feet = 45*51 feet^2 = 2295 ft ^2
Since there are 1/3 yard in 1 feet, 51 feet = 17 yards
So the area in square yards = 15*17 yard^2 = 255 yd^2

Answer:
the period of this graph is 2[tex]\pi[/tex]
Step-by-step explanation:
The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.
Let's look at the peaks (maximums).
One is at x = 0 and the next is at x = 2[tex]\pi[/tex]
2[tex]\pi[/tex] - 0 = 2[tex]\pi[/tex]
Therefore, the period of this graph is 2[tex]\pi[/tex]

hello againn
okay, so lets see how 32 can become 20. We can subtract 12, so that is possible. Lets check with our other inputs.
if all inputs - 12 = the output, that is the function.
14 - 12 = 2. 2 is our output, so that is a very good sign.
We cant check the third one, so lets skip that for now.
-2 - 12 = -14, which is our output. (yay!!!)
And we cant fill in the last one, which is okay.
So now we know our function is y = x - 12.
Now we fill in the question marks.
The third one. -6 + 12 = 6. The input for 3. is 6.
Last one, 10 - 12 = -22.
Function: y = x-12
Fill ins, third = 6
Last = -22.

Find the exponential function that contains the points (2,40) and (3,8).
Answer:
Moving from point A (2,40) to point B (3,8) , you move 32 units down and one unit right, meaning your slope is 32x.
Your y-intercept is 104.
Altogether, your function (in y = mx + b format) will look like this:
y = -32x + 104
