Answer:
[tex]y = \frac{3}{4}x -3[/tex] --- Slope intercept
[tex]4y - 3x =- 12[/tex] --- Standard form
Step-by-step explanation:
Given
The attached linear graph
Required
The equation
Select any two points on the line
[tex](x_1,y_1) = (0,-3)[/tex]
[tex](x_2,y_2) = (4,0)[/tex]
Next, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{0 --3}{4 - 0}[/tex]
[tex]m = \frac{3}{4}[/tex]
The slope intercept is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = \frac{3}{4}(x - 0) -3[/tex]
[tex]y = \frac{3}{4}(x) -3[/tex]
[tex]y = \frac{3}{4}x -3[/tex]
Multiply through bu 4
[tex]4y = 3x - 12[/tex]
Subtract 3x from both sides
[tex]4y - 3x =- 12[/tex] --- Standard form

Answer:
(a) 1
Step-by-step explanation:
For large variable magnitude, the value of a rational function approaches the ratio of the highest-degree terms of the numerator and denominator*. Here, that is ...
x/x = 1
f(x) approaches 1 as x approaches infinity.
__
* The function approaches the line or curve defined by the quotient. (The remainder is ignored in this case.) Here, f(x) = 1 + 3/(x-3), so the quotient is the constant 1.

Step-by-step explanation:
The coordinate point of point B (x₁, y₁) will be (−4, 10). Then the correct option is D.
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
Point A is located at (2, 6), and point M is located at (−1, 8). If point M is the midpoint of segment AB.
Then the coordinate of the point B(x₁, y₁) will be
We know that the mid-point formula
[tex]\rm (x, y)= \left ( \dfrac{x_1+x_2}{2}, \ \dfrac{y_1+y_2}{2} \right )\\\\(-1, 8)=\left ( \dfrac{2+x_2}{2}, \ \dfrac{6+y_2}{2} \right )\\\\ \dfrac{2+x_2}{2}=-1 \\\\2+x_2=-1\times 2\\\\x_2=-2-2\\\\x_2=4\\\\\dfrac{6+y_2}{2} =8\\\\6+y_2=8\times 2\\\\6+y_2=16\\\\y_2=16-6\\\\y_2=10[/tex]
Then the coordinate point of B (x₁, y₁) is (−4, 10).
Hence, the coordinate point of point B (x₁, y₁) will be (−4, 10). Then the correct option is D.

There are 80 new houses being built in a neighborhood. Last month 2/5 of them were sold. This month, 1/8 of the remaining houses were sold. How many houses are left to be sold?
Answers
Answer:
41 houses
Step-by-step explanation:
Given the following data;
Total number of house = 80 houses
Fraction sold in the 1st month = 2/5
Fraction sold in the 2nd month = 1/8
To find the number of houses left unsold;
Number sold in the 1st month = 2/5 * 80
Number sold in the 1st month = 160/5
Number sold in the 1st month = 32 houses
Numbers of houses left = 80 - 32 = 48 houses
Number sold in the 2nd month = 1/8 * 48
Number sold in the 2nd month = 48/8 = 7 houses
Number of houses left = 48 - 7 = 41 houses

a. must
b. might or might not
c. must not
Answers
Answer:
b. might or might not
Step-by-step explanation:
Theorem:
If f is a continuous function in a bounded interval, it must have an absolute maximum.
In this question:
The interval is 2x^4+6y^2 >= 152, which goes to infinite, meaning it is not bounded, and so the function might or might not have an absolute maximum, and the correct answer is given by option b.
Answer:
b. might or might not

The Martian monetary system uses colored beads instead of coins. A blue bead is worth 3 Martian credits, and a red bead is worth 7 Martian credits. Thus, three blue beads are worth 9 credits, and a blue and red bead together are worth 10 credits, but no combination of blue and red beads is worth 11 credits. Using Induction, prove that for all n ≥ 12, there is some combination of blue and red beads that is worth n credits. Clearly state the type of Induction you have used to prove the problem
Answers
Answer:
"a" is showing the number of blue beads
"b" represents the number of red beads in a combination
let "n" show the number of credits.
We get the following equation:
n = 3a + 7b.
Now, we want to prove that for all n ≥ 12, there is some combination of blue and red beads that is worth n credits, there are a, b in N such that:
n = 3a + 7b
Hence we will prove this by induction.
Base Cases: n = 12.
Applying the formula clearly 12 = 3*4+7*0.
n = 13
Applying the formula clearly 13 = 3*2+7*1.
n = 14.
Applying the formula clearly 14 = 3*0+7*2.
Induction Step: Assume that for all 12<=k<n there are x, y in N such that
k = 3x + 7y. We will now prove that there are a, b in N such that n = 3a + 7b.
By the induction hypothesis we know that there are x, y in N such that n-3 = 3x + 7y.
Hence n = n - 3 + 3 = 3x + 7y + 3 = 3(x + 1) + 7y, so choosing a = x + 1
and b = y we see that n = 3a + 7b.
Therefore by induction, the claim is true for all n ≥ 12
