To draw a graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of ___, a second point by going over 3 and up ___, and then draw a line through the points
Answers
At least that’s what I got
For drawing the graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of __7_, a second point by going over 3 and up __8.25__, and then draw a line through the points.
How to know if a point lies in the graph of a function?All the points (and only those points) which lie on the graph of the function satisfy its equation.
Thus, if a point lies on the graph of a function, then it must also satisfy the function.
For this case, the equation given to us is:
\(y = \dfrac{3}{4}x + 7\)
Any equation of the form \(y = mx + c\) where m and c are constants and x and y are variables is the equation of a straight line.
For a straight line to be characterized, only two points are sufficient.
For x = 0, the y-coordinate would be such that it would satisfy the equation \(y = \dfrac{3}{4}x + 7\)
Putting x = 0, we get:
\(y = \dfrac{3}{4} \times 0 + 7 = 7\)
Thus, y-coordinate of the point on this line whose x-coordinate is 0 is 7. Thus, (0,7) is one of the point's coordinate on the considered line.
Putting x = 3, we get:
\(y = \dfrac{3}{4} \times 3 + 7 = 9.25\)
Thus, y-coordinate of the point on this line whose x-coordinate is 0 is 9.25 . Thus, (0,9.25) is another of the point's coordinate on the considered line.
Thus, for drawing the graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of __7_, a second point by going over 3 and up __8.25__, and then draw a line through the points.

Find the least positive integer, written only by numbers 0, 1 and 2, which is divisible by 225.
Answers
9514 1404 393
Answer:
1,222,200
Step-by-step explanation:
A search using a computer program found ...
5432 × 225 = 1,222,200
__
1000 mod 225 = 100
4 × 225 = 900
This suggests that if we have some number of thousands whose digits total 9, that we will have the number of interest. Of course, we can add 200 to some number of thousands with a digit total of 7. The smallest such digit total will be had with the number 1222 using the specified digits {0, 1, 2}. This gives rise to the result above: 1222×1000 +200 = 1,222,200. It also explains why moving the 1 to the right will also give a multiple of 225.

You have 12 coins. Some quarters and dimes. You have a total of $2.40, how many of each coin do you have?
Answers
Answer:
8 quarters and 4 dimes
Step-by-step explanation:
4 quarters = 1 dollars
4 quarters = 1 dollars
4 dimes = 40 cents
2.40$
============================================
Work Shown:
d = number of dimes
q = number of quarters
1 dime = 10 cents
d dimes = 10d cents
1 quarter = 25 cents
q quarters = 25q cents
d+q = 12 since we have 12 coins total
q = -d+12 after solving for q
10d+25q = total value in cents
10d+25q = 240
10d+25(-d+12) = 240 ... plug in q = -d+12
10d-25d+300 = 240
-15d+300 = 240
-15d = 240-300
-15d = -60
d = -60/(-15)
d = 4
q = -d+12
q = -4+12
q = 8
Since d = 4 and q = 8, this means we have 4 dimes and 8 quarters
-----------------------------
Check:
4 dimes = 4*10 = 40 cents
8 quarters = 8*25 = 200 cents
(4 dimes) + (8 quarters) = (40 cents) + (200 cents) = 240 cents
240 cents = 240/100 = $2.40
We have 4+8 = 12 coins total

If the daily overhead charge is Rs. 2600, find the profit function. Also find the profit if 360 units of an item are produced and sold daily?
Answers
Answer:
Y(x) = 10x - 2600
Profit= RS. 1000
Step-by-step explanation:
Amount sold per item=RS. 50.
Cost of manufacturing= RS. 36.5
Distributor charges= Rs 3.5
Daily over head charge= RS.2600
Profit function Y (x)
Y (x) =x(50) -36.5(x) -3.5(x)-2600
Y(x) = (50-36.5-3.5)x-2600
Y(x) = 10x - 2600
If x= 360
Profit Y = 10(360) - 2600
Profit Y = 3600-2600
Profit = 1000

=======================================================
Explanation:
Use the two given angle measures (Y and Z) to find angle X.
X+Y+Z = 180
X+141+25 = 180
X+166 = 180
X = 180-166
X = 14
Angle X is 14 degrees.
-----------
Now use the law of sines to determine side length z.
Make sure your calculator is in degree mode.
z/sin(Z) = x/sin(X)
z/sin(25) = 830/sin(14)
z = sin(25)*830/sin(14)
z = 1449.9438
z = 1449.9 cm is the final answer.
The solution is : the length of z, to the nearest 10th of a centimeter is, 1449.9 cm.

A line segment has endpoints P (1, -1) and Q (-9,-6). What are the coordinates for point R, also on the segment, that will place point R 3/5 of the distance from P to Q?
Answers
A line segment has the following endpoints
\(P(1,-1)\: and\: Q(-9,-6)\)We are asked to find the coordinates of point R, such that the point R will be 3/5 of the distance PQ.
Let us first find the distance from P to Q.
The distance between two points P and Q is given by
\(PQ=\sqrt[]{\mleft({x_2-x_1}\mright)^2+\mleft({y_2-y_1}\mright)^2}\)Let us substitute the given points into the above distance formula
\(\begin{gathered} PQ=\sqrt[]{({-9_{}-1_{}})^2+({-6_{}-(-1)_{}})^2} \\ PQ=\sqrt[]{({-9_{}-1_{}})^2+({-6_{}+1_{}})^2} \\ PQ=\sqrt[]{({-10})^2+({-5})^2} \\ PQ=\sqrt[]{100^{}+25^{}} \\ PQ=\sqrt[]{125} \\ PQ=11.18 \end{gathered}\)Now let us find the coordinates of point R such that R is equal to 3/5 of PQ.
So the ratio is m:n = 3:5
\(R_x=\frac{nx_1+mx_2}{n+m},R_y=\frac{ny_1+my_2}{n+m}\)Let us substitute the given values into the above formula
\(\begin{gathered} R_x=\frac{5\cdot1+3\cdot(-9)}{3+5},R_y=\frac{5\cdot(-1)+3\cdot(-6)}{3+5} \\ R_x=\frac{5-27}{8},R_y=\frac{-5-18}{8} \\ R_x=\frac{22}{8},R_y=\frac{-23}{8} \\ R_x=\frac{11}{4},R_y=\frac{-23}{8} \end{gathered}\)Therefore, the coordinates of the point R is
